How To Instal A Septic Tank Filter Outside The Tank? (TOP 5 Tips)

  • Common installation involves connecting the effluent filter within the tank system. However, another option is to install the septic filter outside the tank in a separate chamber that’s close to the septic tank. The outside chamber must be installed close to the septic tank, upstream from the drain field.

Where does the filter go on a septic tank?

Most septic tank filters are located inside of the baffle of the tank. For this reason the filters are very important, since they help regulate the flow to the area of drainage. The septic tank filters are very important in situations where waste is actually being delivered from the septic tank to the drainage area.

Where does an effluent filter go?

Effluent filters go in the tank and take the place of the exit baffle. Any water leaving the tank must first go through this filter. Effluent filters are designed to prevent larger solids from leaving the tank and plugging up the drainfield.

Are septic tank filters necessary?

Proper septic tanks should be fitted with an effluent filter or tank outlet filter. This is installed in the outlet of the tank and helps prevent anything other than liquid getting into the leach field (or clogging the outlet pipe).

Does a septic tank need an inlet baffle?

Inlet baffles are needed for proper performance of the septic tank. Raw sewage from the residence is directed by the baffle downward into the middle zone of the septic tank. This means the effluent follows a tortuous path through the tank, which provides the necessary detention time for the larger solids to settle out.

How do you know if your septic tank has a filter?

Watch for signs that it might be time for cleaning. If the drains in your home seem sluggish or there is a gurgling noise coming from drains around your house, it could be the effluent filter. It may also be a sign that its time to have your septic tank pumped and cleaned if it has been a while.

Do all septic tanks have filters?

First, not all septic tanks have a filter, especially the older septic tanks. Now many government agencies require or recommend a filter when a septic tank is installed. Cleaning a septic tank filter is different than pumping out a septic tank and cleaning it.

How often do you need to clean a septic tank filter?

As a rule of thumb, you should always clean the septic tank filter when doing your routine pumping. But since this will typically be after a couple of years, you should inspect the filter twice a year – just before winter and right after winter. It is best to use a filter that has an alarm.

What is an effluent filter for septic tank?

Effluent filters are devices that can be affixed to outlets of septic tank and grease trap as pictured at right (Figure 1). The filter is a primary screening barrier designed to reduce the volume of solids passing out of the tank and through to the soil absorption system (SAS).

What does a Zabel filter do?

Zabel’s patented filter design reduces and traps solids in the filter by allowing them to slough off and fall back into the tank for further digestion. Slots rather than mesh screens provide less surface area for solids to attach and promote the sloughing action.

Building and retrofitting a septic tank effluent filter

Tuxtalk, photographs, e-cards, and an online store may be found at home|electronics|toolbox, science club, and online shop. Septic systems are biological waste water treatment systems that are installed on-site. People who live in urban areas have a tendency to believe that their water treatment systems are inferior than municipal water treatment systems. This is not correct. They have the potential to be more effective and cause less pollution of rivers than municipal water treatment plants.

You’ll need a little breathing room.

You are aware that it is your obligation to keep it in good condition.

I have a system that dates back to the 1950s and it has been operating without issue for many years.

  • Bacteria metabolize solid waste, transforming it into water, carbon dioxide, dead cell mass, and mineral ash as waste products.
  • These bacteria perform a critical function in your body.
  • The septic tank has the following appearance: septic tank, concrete, older design, 1950s This is a tank from the 1950s, a time when plastic pipes were not widely available.
  • The chambers in my tank are divided by wall pieces of varying heights, with lighter items such as oils and soaps accumulating at the top and heavier materials accumulating at the bottom of each chamber.
  • For every unit of water that goes into the tank from the left, the same quantity of water flows out of the tank from the right.
  • As a result, you may expect a tiny quantity of solids to be discharged from this sort of tank.
  • Modern tanks, in addition to having an effluent filter, also include an input baffle to prevent the floating scum layer from clogging the inlet pipe; however, this is not possible with this earlier type since the inlet pipe is significantly higher than the exit pipe.

It is not essential to include an input baffle of this type.

Just before pumping and cleaning the septic tank, the second chamber was pumped and cleaned.

Although the layer is relatively thin, it has the ability to leak out of the pipe and into the septic drain field, where it might block the system over time.

It was for this reason that I created my own filter, which consisted of a finestainless steel mesh.

The filter is contained within a tee-pipe that has been expanded slightly to the bottom.

The filter is just a role that is closed at the bottom of the hierarchy.

Please see below a few photographs of the filter that I created.

At the very top of the pipe, it seals the area between the filter and the inside of the pipe.

Everything, including the handle that is used to remove the filter, is constructed of stainless steel.

I took advantage of the chance to fix some of the cement wall as well.

After the tank had been pumped and the water level had been reduced, I applied a specific re-surfacing cement to the surface.

This is necessary in order to achieve appropriate bonding.

Despite its age, the tank remains in superb condition. A new 4-inch plastic pipe had been installed in 1997 to replace the outgoing line, which had originally been constructed of ceramic material. As a result, installing this plastic tee in conjunction with the filter was straightforward.

6 month later, Oct. 19, 2019

It was six months later that I opened the tank again to check on the filter’s performance. As a result of the tank lid not being immediately over the filter, I did not have the option of installing a longer filter, which would have been more appropriate. In order to do this, the filter has to be short enough to be able to enter and remove it both quickly. However, it appears that the capacity is only sufficient for a period of less than six months. Despite the fact that the filter was extremely “dirty,” it was still allowing water to pass through.

  • As soon as I removed the filter, I observed that there was an increase in the amount of water flowing.
  • It was not a free-flowing stream.
  • The filter was constructed entirely of stainless steel, with the exception of the handle bar at the top, which was constructed of a different stainless steel than the filter mesh.
  • It was created by using a stainless steel cooking utensil for the handle bar.
  • Organic debris coated in black anaerobic bacteria on the filter might explain the black color of the particles on the filter.
  • As predicted, the system is performing as planned and is safeguarding the septic field.
  • It’s possible that I’ll create a filter that can bend a little bit when it’s inserted and removed.

Update, Nov. 24, 2019

I’ve created a new filter with a flexible part in the middle that may be adjusted as needed. This enables me to make it longer despite the fact that the tank cover is in an inconvenient place. Here’s a comparison of the old and new filters side by side. The longer filter should be able to withstand significantly longer cleaning cycles. Despite the fact that we have already received some snow, it was still able to open the septic tank. Old filter, taken on the 22nd of November, one month after the prior cleaning.

As can be seen, the older (shorter) filter did not acquire a significant amount of organic material in such a short period of time.

I have no clue, but I will look into it over the course of the next few months.

In its place, I have a filter that is twice as long and should be large enough to keep me comfortable throughout the winter, as there will be no convenient way to get to the tank for at least the next four months. A 3-5-foot layer of snow will blanket the ground.

Update, March 28, 2020

Although there is still some snow in the rear, the area surrounding the tank is clear of snow, and the temperature is a pleasant +3 degrees Celsius. This implies that I can use the garden hose and that I can open the tank to examine how the longer filter is doing in comparison to the shorter filter. From left to right: no rising water levels with this filter, the filter is now brown rather than black (winter? ), glue dots reacting with something in the water, and the filter is no longer black.

  • This indicates that it is not blocking the flow of information.
  • There is no longer any black dirt on the filter; instead, there is brown dirt.
  • I used some 100 percent waterproof glue to keep the thread that holds the bottom cover in place.
  • Some sort of chemical interaction with anything in the water is suspected, or the glue may not be waterproof in the first place.
  • This is a fantastic outcome, and I am quite pleased with it.

Update, Apr 11, 2020

I’ve been attempting to determine how much water is passing through this filter because the amount of water should be exactly related to the size of the filter required. No irrigation water is utilized in the garden during the winter months. As a result, the amount of freshwater eaten equals the amount of water that passes through this filter. Because we have four people living in the house, we use a total of 108 gallons of water each day, which is equal to 408 liters per day. This is equivalent to 102 liters each day and per person.

You may use this information to determine if a comparable filter should be constructed in a larger or smaller size based on your water use.

Update, Sep. 26, 2020

The filter is in fine functioning order. I’m cleaning it today because I’ll be removing the garden hose for the winter in the near future. When compared to the outflow, the water level in the tank is not significantly higher. I was unaware that I had uneven grass growth over my septic field until I installed this filter, and now that I have had it for about two years, I can report that the grass growth is more even than it was before. In other words, it is possible that some organic muck was retained within the pipes in the field, and the field has since recovered.

Update, Oct. 26, 2021

The tank had been drained earlier this year, in the springtime. I did not completely clean the filter at that time; instead, I sprayed it with the garden hose from the side while it was still in the tank to give it a little cleaning. Now that it’s October, I’m cleaning the filter in preparation for the onset of the winter. It’s quite jammed. In this case, the water level was somewhat higher (1 1/2 inch), and the material on the filter was a dark gray hue. Even with its larger capacity, proper filter cleaning is still necessary every 6 months at the very least.

  1. What is the significance of the color black?
  2. Is it connected to the fact that the tank was drained out in the spring season?
  3. It undergoes some transformation.
  4. Unless I cover them with with dirt, they will not be completely air tight.
  5. This closes the valve, preventing oxygen from entering the tank.
  6. It’s possible that some oxygen gets taken into the tank, which alters the biological process.
  7. It’s only a hypothesis.

The filter continues to meet my expectations. It appears to be effective in keeping the field clean. Getting back to “No preservatives were used” 2004-2022 Guido Socher is an Italian actor and director.

Septic tank effluent filter kits for any home sewage tank system<

It is mandatory that every greywater or septic tank system be equipped with a filter in order to prevent particle matter from entering the leach field. Particulates aggregate over time to produce a black sludge ‘bio-mat’ layer at the bottom of your leach field, which can be seen in the photo above. It clogs the soil, impairs percolation, and finally causes complete failure, resulting in sewage backing up into the home. Septic tanks with two compartments and a septic filer on the outlet side of the second compartment are considered best practice.

  • Due to the high cost of shipping such huge equipment, purchasing tanks from a local supplier will save a significant amount of money.
  • Tanks as little as 100 gallons and 4 feet tall are sufficient for a greywater or septic system, but in most parts of the nation, it is necessary to add a second compartment tank of at least 300 to 500 gallons.
  • However, the “self-cleaning” function of the single compartment septic tank may be hampered by the installation of the filter.
  • This includes a filter, a housing tee that fits Sch40 or SDR35 four-inch pipe, and a handle extension kit, among other accessories.
  • You will never have to replace this septic filter because it is designed to last a lifetime.
  • With a universal hub for use with either SDR35 thin-wall or Sch40 thick-wall 4 inch diameter pipe, our time-tested NSF/ANSI certified standard46 septic tank filter assembly is the perfect solution.
  • It has 80 lineal feet of filtration area and can handle a treatment volume of up to 800 gallons per day.

Instead of a mesh screen, a series of 1/16 inch horizontal filtering holes is used, which gives far less surface area for particles to attach themselves to.

Filter is equipped with a locking tab to prevent it from ‘floating’.

This low-maintenance septic filter design never needs to be replaced.

Please keep in mind that these PL-68 drop-tees may or may not be approved for use as inlet tees in your local jurisdiction.

Inspectors may grant permission to cut the PL-68 down to the required depth.

There are differences across counties and inspectors, but the bottom of the input pipe is usually 12 inches or less below the tank water level on a typical day.

The liquid surface is measured at the outflow pipe, which is lower in elevation than the entrance pipe. In order to avoid sewage back-up, the inlet hole is typically two inches higher than the outflow hole.

Filter housing is black ABS plastic so use ‘multi-plastic’ cement with white/green PVC pipe.Always purple primer all pipe joints first, before applying your solvent weld cement.

Each compartment should be checked annually, and the first compartment should be pumped before enough sediments collect in the first compartment to cause it to overflow into the second compartment. Typically, tanks are less than sixteen inches in diameter – check with the manufacturer of your tank. To examine the level of solids at the bottom of your septic tank, wrap a piece of white towel around the end of a long pole and poke it into it. If your septic tank is healthy and correctly proportioned, it may never need to be pumped.

  1. As a result of the accumulation of particles, grease, and sediments in the leach field percolation region, the ‘biomat’ ultimately fails and needs to be replaced.
  2. If you reside in a very cold environment, you should never have your tank pumped in the fall or winter; you should only have it pumped in the spring.
  3. After having your septic tank pumped, make sure to promptly refill it with water.
  4. When the earth is damp or when the tanks are not adequately bedded in lots of gravel, this is especially true (selective, draining backfill).
  5. An empty concrete and fiberglass tank may fracture and leak if subjected to significant pressure, and it will ultimately need to be removed and replaced.
  6. Larger particles are prevented from exiting the tank and jeopardizing the leach field by plugging soil pores and causing failure.
  7. Septic filters are a low-cost form of insurance that may be readily installed in the second compartment of your septic tank.
  8. Supplemental septic system additives are a complete waste of money, and virtually all of them are detrimental to the environment.
  9. In reality, this just permits smaller particles to flow past the septic filter (if you are fortunate enough to have one), where they re-unite and create a dense bio-mat in the leach field.
  10. None of these septic cleaning and/or maintenance products has received FDA approval since none of them has been shown to be effective.
  11. For me, the decisive element is whether or not you would wish to see these additions make their way into your drinking water from your well.

A correctly built septic tank (with two compartments and sufficient capacity) will function perfectly well without the use of chemicals. Avoid using any of the septic system chemicals that seem too good to be true on the market today.

  • You must immediately refill the water in your septic tank following the pumping.
  • When the earth is damp or when the tanks are not adequately bedded in lots of gravel, this is especially the case (selective, draining backfill).
  • They should always park at least 20 feet away from the tank.
  • During the annual tank inspection, install an effluent septic filter and clean it out.
  • Sieve filters also prevent smaller particles from exiting the tank (bio-mat).

It is important not to use SEPTIC TANK ADDITIVES in your system.

It is said that the use of septic system additives will help to break down fatty and solid materials in the septic tank.

The flushing of septic system chemicals into your septic tank is not recommended by us.

They will, at the at least, cause no damage to your septic system or the environment, and will just waste your time and money in the process.

Having something in one’s drinking water and consequently in one’s digestive system that has the potential to digest raw sewage should make one nervous.

In most cases, no chemicals are required in a well built septic tank (two compartments and a sufficient size). Avoid using any of the septic system chemicals that seem too good to be true that are now on the market.

What do I do if My Septic Alarm is Going Off?

In the event that your septic alarm goes off, it may surely create some anxiety and uncertainty; and if you happen to be experiencing this right now, then you’ve arrived to the correct location! Don’t be concerned; it does not necessitate urgent action. Instead, take your time to go through this full essay so that you will be prepared to act now or in the future if the situation arises. What Septic Systems Are and How They Work The alarm works in conjunction with the septic system to alert you when the water level within the pump tank has increased to an unsafe level or has decreased to an unsafe level.

  • The timer is in charge of regulating the time intervals during which the pump is permitted to pump wastewater into the drainage system.
  • Thus, during periods of excessive water use, the drain field is kept from getting overflowing, which might cause damage to the drainage system.
  • A large amount of water is injected into the system in between pumping cycles for whatever cause, and the water has nowhere else to go but back into the system’s pump tank.
  • Depending on how much water was and continues to be put into the system and how the pump is set up to operate on a timer, it may take many pumping cycles until the water levels are returned to normal.
  1. If you’ve ever had your septic alarm go off, you know how much stress and uncertainty it can create. If you’re now experiencing this, you’ve come to the perfect spot! Don’t be concerned
  2. It does not necessitate urgent action. Instead, take your time to go through this full essay so that you will be prepared to act now or in the future if the situation warrants. What Septic Systems Are and How They Function In conjunction with the septic system, this alarm is designed to alert you when the water level within the pump tank has increased over a certain level or decreased below a certain level. All septic systems with pumps are required to have some type of timer installed. Using a timer, you may control how much wastewater the pump is permitted to pump into the drain field at different times of day. At certain periods of the day, these precise time intervals will occur. Thus, during periods of excessive water use, the drain field is prevented from getting flooded, which might cause damage to the drainage system. How Does a Problem Occur When There Is One? A large amount of water is brought into the system in between pumping cycles for whatever cause, and the water has nowhere else to go but back into the system’s storage tank. As a result, the water level within the pump tank will rise until the timer enables the pump to be turned back on. It may take many pumping cycles until the water level in the system returns to normal levels, depending on how much water was and continues to be injected into the system during the time intervals specified by the timer. Causes of the alarm going off that might occur
  1. Somehow, groundwater is making its way into the system. If there is an excessive amount of standing water surrounding the septic tanks, whether generated by rain or another source, the water may seep into the tanks and cause the internal water level to rise.
  1. It’s possible that one of the components of the septic system is malfunctioning. If anything goes wrong with your system — including the pump and floats — the alarm and timer will go off and the septic system will stop working correctly.

The Best Thing to Do If Your Alarm Goes Off Alternatively, if you hear an alert, you should press the red button or turn on the alarm box. The alarm will be turned off as a result of this action. There should be a red light and a green light on the alarm box, which should be situated someplace on the unit. The green light indicates that the alarm is operational and should be left on at all times. It is shown by a red light if the alarm is getting a signal from the pump tank indicating that the water level is increasing above or decreasing below what is expected.

  • If the breaker occurs to be tripped, look around the septic tanks to see if there is any standing water.
  • It is possible that the red light on the alarm box will go out on its own after allowing the septic system to operate for a couple of pump cycles (which should take approximately 10-15 hours).
  • If the red light turns off, it signifies that the system is operating properly and that it only needs to catch up with the extra water that has overflowed into the storage tank.
  • To be clear, an alarm signal from the septic system does not always imply that sewage is about to back up into the house right away.
  • Do you require septic system repair on a regular basis or emergency service?

How to Clean Your Septic System Filter

Have you found that your drains are slow to drain? Have you ever had water back up into your drains or toilets? It may be necessary to clean the filter in your septic system. A clogged filter makes it impossible for wastewater to exit your septic tank.

What is the Filter for, Anyway?

Septic tanks collect wastewater (effluent) that exits your house after it has been treated. Generally speaking, solid waste sinks to the bottom of the tank, while oils and grease float to the top. A system of T-shaped pipes, known as baffles, is installed at the tank’s entrance and exit. Baffles, sometimes known as “tees,” are devices that prevent solid waste from escaping a septic tank. Some solid waste, on the other hand, may still be able to escape. Your septic system features a filter, which is often located in the outflow baffle, that collects the solids that are departing.

Solids accumulate in the filter, which causes drainage to become sluggish or even cause water to back up into your home when the filter catches them.

How Do I Clean the Filter?

Water that exits your home is collected in a septic tank, which is used to treat the waste water. Floating oils and grease float to the top of the tank, while solid waste sinks to the bottom. Baffling is installed at the tank’s inlet and outlet, which are T-shaped pipes. Tees, or baffles, are devices that prevent solid waste from leaving a septic tank. Some solid waste, on the other hand, may still be able to get out. In order to capture the particles that are escaping from your septic system, it features a filter, which is normally located in the exit baffle.

Solids accumulate in the filter, which causes drainage to be slowed or even water to back up into your home as a result of the filter collecting them.

What size of septic tank do I need?

Probably one of the last things on your mind when you are constructing a new house is the location of your septic system. After all, shopping for tanks isn’t nearly as entertaining as shopping for cabinetry, appliances, and floor coverings. Although you would never brag about it, your guests will be aware if you do not have the proper septic tank placed in your home or business.

septic tanks for new home construction

The exact size of the septic tank is determined mostly by the square footage of the house and the number of people who will be living in it. The majority of home septic tanks have capacities ranging from 750 to 1,250 gallons. A 1000 gallon tank will most likely be required for a typical 3-bedroom home that is smaller than 2500 square feet in size. Of course, all of this is dependent on the number of people who live in the house as well as the amount of water and waste that will be disposed of through the plumbing system.

For the most accurate assessment of your septic tank needs, you should speak with an experienced and trustworthy sewer business representative. They can assist you in planning the intricacies of your septic system, including which sort of septic system will be most beneficial to you.

planning your drainfield

This is mostly determined by the square footage of the house and the number of people that will be living in it, as well as other factors. A typical household septic tank holds between 750 and 1,250 gallons of water. Typically, a 1000 gallon tank will be required for a three-bedroom home that is less than 2500 square feet in size. It goes without saying that the amount of water and garbage that is placed into the system is directly proportional to the number of people who live in the residence.

A reputable septic firm is the most dependable source for determining the appropriate size septic tank for your home.

  • Vehicles should not be allowed on or around the drainfield. Planting trees or anything else with deep roots along the bed of the drain field is not recommended. The roots jam the pipes on a regular basis. Downspouts and sump pumps should not be discharged into the septic system. Do not tamper with or change natural drainage features without first researching and evaluating the consequences of your actions on the drainage field. Do not construct extensions on top of the drain field or cover it with concrete, asphalt, or other materials. Create easy access to your septic tank cover by placing it near the entrance. Easy maintenance and inspection are made possible as a result. To aid with evaporation and erosion prevention, plant grass in the area.

a home addition may mean a new septic tank

Do not make any big additions or renovations to your house or company until you have had the size of your septic system assessed. If you want to build a house addition that is more than 10% of your total floor space, increases the number of rooms, or necessitates the installation of new plumbing, you will almost certainly need to expand your septic tank.

  • For a home addition that will result in increased use of your septic system, your local health department will require a letter from you that has been signed and authorized by a representative of your local health department confirming that your new septic system is capable of accommodating the increase in wastewater. It is not recommended that you replace your septic system without the assistance of a certified and competent contractor.

Your septic system is normally buried between four inches and four feet underground, depending on the climate.

How to Install a Septic System

Documentation Download Documentation Download Documentation In rural regions of the nation where waste water treatment is not accessible, private on-site wastewater treatment systems (POWTS), also known as septic systems, are utilized largely to treat waste water. Gravity fed/conventional systems are divided into two broad categories: 1. gravity fed/conventional systems and 2. alternative (pump) systems, which include aerobic treatment units (ATUs.) In most cases, electric pumps are used in alternative systems.

However, in many health jurisdictions across the United States, it is still feasible for an individual property owner with heavy equipment operation skills to utilize a backhoe to establish a septic system on their land.


  1. 1 Make a plan and design for your system. Performing a site survey and conducting a percolation (soil) test on the area where the POWTS is to be placed are both required initial steps in any septic system installation. In order to create a system, it is necessary to first gather information from surveyors and conduct a soil test. It is then possible to submit an application for the necessary permissions and approvals.
  • The following are some of the conclusions from the site survey that have an impact on the design:
  • Available space
  • Terrain
  • Intended purpose and projected water demand depending on the size of the residence or building that the system will serve
  • Location of the well and/or nearby wells
  • And other factors.
  • The following are examples of soil test findings that have an impact on the design:
  • The soil type and layering (sand, clay, rock, and where it is placed in relation to depth)
  • The soil’s ability to drain and filter wastewater
  • And the soil’s ability to drain and filter wastewater
  1. 2Wait for clearance before proceeding. The system may be deployed once all of the relevant permissions and approvals have been obtained. Make certain that all of the steps listed below are carried out in accordance with all applicable laws, plumbing rules, and building codes. Advertisement

Please keep in mind that the following procedure assumes that the system is being installed for the first time and not as a replacement.

  1. Please keep in mind that the following procedure is predicated on the assumption that the system is being installed for the first time rather than being replaced.
  • Backhoe, laser transit, and grade pole are all included. A 4″ Sch. 40 PVC pipe (and fittings, if necessary)
  • A 4″ ASTM D2729 perforated pipe
  • A 4″ASTM D3034 pipe and fittings
  • A 4″ Sch. 40 vent cap and test cap
  • PVC primer and adhesive
  • A 4″ Sch. 40 vent cap and test cap The following tools will be required: Saw (either hand saw or cordless reciprocating saw)
  • Hammer drill and bits (for drilling through walls if necessary)
  • The following items are required: hydraulic cement (to seal surrounding pipe if pipe is going through wall)
  • Shovel
  • Stone measuring an inch and a half and cleaned (amount varies depending on system size)
  • Tape measurements (both ordinary and at least a 100-foot-long tape)
  • Septic fabric (cut to 3′ length or less from a roll)
  • Septic tank and risers (concrete or plastic if allowed)
  • Riser sealant such as Con-Seal (for concrete) or silicone caulk (for plastic)
  • A septic filter (such as a Zoeller 170 or similar) if one is necessary
  • A distribution box (either concrete or plastic, if more than two laterals are being run)
  • And a septic tank.
  • 2 Determine the location of the entrance to the building in relation to the location of the septic tank. Make an excavation at least 2 feet deep and drill a hole through the wall, or go deeper and drill a hole beneath the footing, depending on your preference or the need. Because this is precisely what a gravity-fed system is designed to accomplish, expect the flow to continue to flow downhill from here. When transferring waste from the tank to the drain field, it does not employ any mechanical methods other than gravity.
  • The pipe should be 4″ Sch. 40 and should extend at least five feet outside the structure toward the tank, either through the wall or beneath it. Set it level where it will pass through a wall or under a footing, and from there, run it with approximately 1/8″ of pitch (slope) every foot of length toward the septic tank until it reaches the tank. If necessary, go even farther into the tank or all the way into the tank. If this is the case, switch to 4″ 3034 with the appropriate adaptor and pipe 3034 toward the tank.
  • Make sure you use a test cap on the end that will be entering the building. It is recommended that if you are going through a wall, you seal the area around the hole with hydraulic cement both inside and outside
  • Do not run too much pitch out to the tank. If there is an excessive amount, the water will run away quicker than the sediments, resulting in the solids remaining in the pipe. Additionally, depending on the depth of your drain field and how close it will be to the tank’s outflow, there may not be enough pitch to get to the drain field.
  • 3 Dig a hole large enough to accommodate the installation of the concrete aerobic tank below ground. Make use of the laser transit to “shoot” the top of the pipe that leads out to the tank with the laser. The distance between the top of the intake and the bottom of the tank is measured in feet and inches. To the number you fired off the top of the pipe, add this (go up on the grade pole) + 1 1/2″ to get the total. The depth of the grade pole has now been adjusted to the desired depth. Using this, continue to drill the hole to the desired depth
  • Prepare your leech field by laying it out and excavating it according to the results of the test performed during the permit application procedure. Maintaining a good flow between the tank and the drain field should be considered when planning out and digging the tank.
  1. 4Use “inch-and-a-half cleaned drain rock” from a neighboring gravel dump to surround the pipe, which is required in most areas. This is necessary in order to keep the pipe stable. For further information on the size of embedment and gravel required, check with your local health department. Five-inch perforated pipe in a gravity drain field does not have a slope from one end to another and has capped ends
  2. Once you have received a green sticker from the health inspector, you must cover the pipe and tank. All places, subject to the restrictions of the local health authority, will be required to cover the drain rock with a specific filter fabric, newspaper, four inches of straw, or untreated construction paper before backfilling.

  1. A pump chamber after the septic tank should be installed The pump chamber, also known as a pressure tank or dosing tank, is where the electric pump is housed, which is responsible for transporting wastewater from one location to another and finally into the drain field for final disposal.
  • Set up the pump chamber in the same manner as you would a septic tank. The effluent pump and floats are housed in the pump chamber, and they are responsible for pumping the effluent out to the drain field at predetermined or scheduled intervals. This is a hermetically sealed system. To ensure that the electrical installation complies with state standards, it is frequently necessary to hire a qualified electrician. It is important to remember that in places with high groundwater, the pump chamber or additional ATUs may remain essentially empty for long periods of time, and that these tanks may need to be safeguarded from floating by the installation of additional weight or other protective features.
  1. Secondly, all construction details, including the layout of all sewers outside of the home, the location and depth of all tanks, the routing and depth of pressurized effluent lines, and other system components, such as the drain field and any additional ATUs, must be consistent with the septic system plans approved by the local county health department. Cover the tank and pressurized lines once the inspector has given his final clearance and the system has been turned on. Advertisement

Create a new question

  • Question I had a tank put, but it isn’t level with the ground. What will be the ramifications of this, and should it be leveled? It is necessary to keep the tank level. It is difficult to predict what it will have an impact on because we do not know which direction it is off level. Question Is it necessary to be concerned about tree roots growing into the drainage area when using a gravity flow kind of tank? Whether or whether you have lateral lines is dependent on the kind of trees that are growing close or above them. Tree species that tend to extend roots into the lateral lines and obstruct them are known as ramifications. Due to the fact that they are buried deep in the ground and surrounded by a pocket of gravel that allows waste water to drain out, they are rarely affected by grass, weeds, and shrubs. Question What is the maximum depth that a pipe may be lowered into the leech bed? The majority of systems require 12 volts “in the form of rock The perforated pipe should be suspended in the top area of the rock
  • It should not be touching the rock. Question Maintaining a lush green grass on or above your pitch is it safe, or is it a good practice? According to what I’ve heard, brown or dead grass is preferred so that your field can breathe more easily. It is necessary for your field to take a breath. The presence of green grass across your field indicates that it is functioning well. With lush grass covering your field, it will be able to breathe. There should be no planting of woody shrubs or trees over the leach field. Question What is the recommended distance between the septic tank and the house/boundary? A minimum of fifty feet is required. States have different laws, but this is the most common distance
  • Nonetheless, other states have stricter laws. Question What is the average amount of soil that goes into a residential leach field? It is dependent on how chilly it becomes. There are no less than 12 in the northern United States “in the leach field’s surface
  • Question Is it possible to build a septic system during the cold months? What you should do will depend on whether or not you reside in a place where the ground freezes. Question What amount of water should I put in the tank to get it going? None. A typical tank holds 1,000 gallons and will fill up quite quickly if used on a regular basis. When liquid effluent is discharged to the drain field, the goal is to catch and pre-treat particles that have accumulated. It is possible that a pump system will require water to prime the pump. Question There is a misalignment between my septic field’s underground line and the pipe on the tank. Is it OK to utilize a 90-degree elbow on my septic tank? As long as you have decent downhill flow, you should be fine. Instead of using a 90, I would use two 45s. Question If I’m installing a septic system, when should I contact an inspector? Immediately following system installation but before earth is used to cover the system in place Always check with the inspector ahead of time to verify that they can satisfy your inspection needs

  • The use of aerobic bacterial additions (which are available at most DIY stores) to maintain a healthy and well functioning system, as suggested by producers on a periodic basis, is contentious. The septic tank is an anaerobic (wet) environment in which the majority of yeasts and other additions will have little or no effect on the sewage being processed. When it comes to installing septic tanks, some old school installers believe that placing an additive, a shovel of muck, or even a dead cat in an empty tank will “start” the process. What naturally enters the tank serves as the only thing that is necessary. The aerobic (wet or dry) component of the system consists of hundreds of square feet of drain field, where additives will do little help even if they make it all the way to the end of the system. The use of chemicals in septic systems has not been the subject of an independent research that has been published in a respectable scientific publication anywhere in the world, including this nation. This will mostly certainly be confirmed by your local health department. Each phase of the building process will almost certainly include an examination by a health inspector before the work can be completed or covered up. On pressurized lines, the use of a sand embedment is recommended in order to reduce the amount of damage caused by moving soil that has a high concentration of clay. When pumps are turned on and off, pressurized lines might move as well. Four inches (10.2 cm) of sand bedding on all four sides of the lines will prevent sharp pebbles from the ground or backfill from wearing holes in the pipe over time

  • Keep the perforated pipe for the leech field in a vertical position while installing it to avoid having the holes in the pipe turn downward. It is necessary to lay the perforated drain field pipe ASTM 2729 dead level, so that the printed line on the pipe is facing up. The perforations on both sides of the pipe are on both sides of the pipe. All of the sections of perforated pipe are cemented together, and the ends of each leach line are capped to complete the installation. So, when waste water enters the pipe, it will fill the pipe to the height of the perforations and overflow from ALL of the holes, utilising the whole leach field as a means of treatment. In certain health authorities, you can utilize waste water to water grass or decorative plants, trees, vegetable gardens, and fruit trees if you place the perforated pipe on a slope. However, the water must first be cleaned by the system (tertiary treatment includes disinfection) in order to prevent pathogens (germs) from the septic system from being discharged into the environment throughout the process. Make sure to check with your local health authority to verify if the practice known as “reuse” is permitted in your community.

How does a septic tank work?

Mr. Fix-It-Up-For-Us. By understanding how a septic tank works—and what may go wrong with it—you will be able to save a lot of money on septic system maintenance in the future.

Understand that a septic system is a cafeteria for bacteria

Bacteria are responsible for the proper operation of a septic system. They decompose garbage, resulting in water that is clean enough to safely trickle down into the earth’s surface. The entire system is set up to keep bacteria healthy and busy at all times. Some of them reside in the tank, but the majority of them are found in the drain field. 1. The septic tank is the final destination for all waste. 2. The majority of the tank is filled with watery waste, referred to as “effluent.” Anaerobic bacteria begin to break down the organic matter in the effluent as soon as it enters the system.

  1. A layer of sludge settles to the bottom of the container.
  2. 4.
  3. Scum is mostly constituted of fats, greases, and oils, among other substances.
  4. Grease and oils float to the surface of the water.
  5. (5) A filter stops the majority of particles from reaching the exit pipe.
  6. The effluent is discharged into the drain field.
  7. Effluent is allowed to leak into the surrounding gravel because of holes in the drain septic field pipe.
  8. The garbage is completely decomposed by aerobic bacteria found in gravel and dirt.
  9. Potable water seeps into the groundwater and aquifer system from the surface.

Septic Tank Clean Out: Don’t abuse the system

Septic systems that have been correctly planned and constructed require just occasional ‘pumping’ to remove the sludge and scum that has built up inside the tank.

However, if you don’t understand how a septic tank works, you may unintentionally hurt or even destroy the system.

  • Drains are used to dispose of waste that decomposes slowly (or not at all). Cigarette butts, diapers, and coffee grounds are all known to cause issues. Garbage disposers, if utilized excessively, can introduce an excessive amount of solid waste into the system. Lint from synthetic fibers is emitted from washing machine lint traps. This substance is not degraded by bacteria in the tank and drain septic field. Bacteria are killed by chemicals found in the home, such as disinfecting cleansers and antibacterial soaps. The majority of systems are capable of withstanding limited usage of these goods, but the less you use them, the better. When a large amount of wastewater is produced in a short period of time, the tank is flushed away too quickly. When there is too much sludge, bacteria’s capacity to break down waste is reduced. Sludge can also overflow into the drain field if there is too much of it. Sludge or scum obstructs the flow of water via a pipe. It is possible for tree and shrub roots to obstruct and cause harm to a drain field. Compacted soil and gravel prevent wastewater from seeping into the ground and deprive germs of oxygen. Most of the time, this is caused by vehicles driving or parking on the drain field.

Get your tank pumped…

Your tank must be emptied on a regular basis by a professional. Pumping eliminates the accumulation of sludge and scum that has accumulated in the tank, which has caused the bacterial action to be slowed. If you have a large tank, it may be necessary to pump it once a year; but, depending on the size of your tank and the quantity of waste you send through the system, you may go two or three years between pumpings. Inquire with your inspector about an approximate guideline for how frequently your tank should be pumped.

…but don’t hire a pumper until you need it

Inspections and pumping should be performed on a regular basis. However, if you’re not afraid of getting your hands dirty, you may verify the sludge level yourself with a gadget known as The Sludge Judge. It ranges in price from $100 to $125 and is commonly accessible on the internet. Once you’ve verified that your tank is one-third full with sludge, you should contact a professional to come out and pump it out completely.

Install an effluent filter in your septic system

Garbage from your home accumulates into three distinct strata. The septic filter is responsible for preventing blockage of the drain field pipes.

Septic tank filter close-up

The septic tank filter is responsible for capturing suspended particles that may otherwise block the drain field pipes. Obtain an effluent filter for your tank from your contractor and place it on the outflow pipe of your tank. (It will most likely cost between $50 and $100, plus labor.) This device, which helps to prevent sediments from entering the drain field, will need to be cleaned out on a regular basis by a contractor to maintain its effectiveness.

Solution for a clogged septic system

If your septic system becomes clogged and you find yourself having to clean the filter on a regular basis, you might be tempted to simply remove the filter altogether. Hold on to it. Solids, wastewater, and scum are separated into three levels in septic tanks, which allows them to function properly (see illustration above). Solids sink to the bottom of the container, where microbes breakdown them. The scum, which is made up of trash that is lighter than water, rises to the surface. In the drainage field, the middle layer of effluent leaves the tank and goes through an underground network of perforated pipes to the drainage field.

  • Gravel and soil operate as biological filters, purifying wastewater as it lowers into the earth (see figure above).
  • Waste particles might flow through the filter and clog the perforated pipes if the filter is not used.
  • The majority of filters don’t need to be cleaned until the tank is pumped, which happens every two to five years on average.
  • A garbage disposal will not be able to break down food particles sufficiently to allow them to flow through the septic tank filtration system.

In addition to flushing plastic waste, nonbiodegradable goods, and cigarettes will clog the system. For additional information on what should and should not be flushed down the drain, contact your local health authority. More information on removing lint from your laundry may be found here.

Get an inspection

The temptation to just remove the filter may arise if your septic system becomes blocked and you have to clean it on a regular basis. It should be preserved. Solids, effluent, and scum are separated into three levels in a septic tank, which allows waste to be separated into three layers (see illustration above). Microorganisms breakdown the particles that settle to the bottom of the tank. It is the scum that floats on top because it is made up of trash that is lighter than water. In the drainage field, the intermediate layer of effluent leaves the tank and is carried away by subterranean perforated pipes.

  • Your state’s health code mandates an effluent filter, so make sure it’s installed and functioning properly.
  • (This filter is not required by all regional regulations.) Waste particles might get through the filter and clog the perforated pipes if the filter was not in place.
  • On the other hand, your filter shouldn’t require cleaning every six months.
  • You may be flushing grease, fat, or food scraps down the drain, which can clog the filter.
  • In order for food particles to flow through the septic tank filter, they must first be broken down by the disposer.
  • In addition to flushing plastic debris, nonbiodegradable goods, and cigarettes will clog the system.

Alternatives to a new drain field

If an examination or a sewage backup indicate that your drain field is in need of replacement, the only option is to replace it completely. As a result, it’s important to talk with a contractor about other possibilities before proceeding with the project.

  • Pipes should be cleaned. A rotating pressure washer, used by a contractor, may be used to clean out the drain septic field pipes. The cost of “jetting” the pipes is generally around $200. Chemicals should be used to clean the system. A commercial solution (not a home-made one) that enhances the quantity of oxygen in the drain field should be discussed with your contractor before installing your new system. Septic-Scrub is a product that I suggest. A normal treatment will cost between $500 and $1,000. Make the soil more pliable. The practice of “terra-lifting,” which involves pumping high-pressure air into several spots surrounding the drain field, is authorized in some regions. Some contractors use it to shatter compacted dirt around the pipes. Depending on the circumstances, this might cost less than $1,000 or as much as $4,000 or more.

Protect your drain septic field from lint

Make sure the pipes are clean and free of debris. A rotating pressure washer, used by a contractor, can be used to clean out the drain septic field pipe. The cost of “jetting” the pipes is around $200. Chemicals should be used to clean the system up. A commercial solution (not a home-made product) that enhances the quantity of oxygen in the drain field should be discussed with your contractor before installation. Septic-Scrub is a product that I highly suggest. The average cost of a treatment is between $500 and $1,000.

Some contractors use this technique to shatter compacted earth around pipes. This might range from less than $1,000 to more than $4,000, depending on the circumstances.

Don’t overload the septic system

Reduce the amount of water you use. The volume of water that flows into your tank, particularly over a short period of time, can be reduced to avoid untreated waste from being flushed into your drain field. Replace outdated toilets with low-flow ones, install low-flow showerheads, and, perhaps most importantly, wash laundry throughout the week rather than just on Saturday mornings to save water.
