How To Cut A Hole In A Concrete Septic Tank? (Best solution)

  • its the concrete debree that will fall in the tank i would atach a peice of unistrut, with drop in anchers and bolts, to over span the hole, then cut it out, and lift the peice up and away

Can you drill hole in concrete septic tank?

You can’t. You have to connect to the pipe from the house. Most septic tanks have a 6″ baffle pipe that the house sewer feeds into. Making a second inlet hole anywhere in the tank would bypass that baffle and create a lot of problems with the tank in the future.

How thick is a concrete septic tank?

The exterior walls of the septic tank are made of concrete, normally 4 inches thick. The concrete is either a minimum of 4,000 or 5,000 PSI concrete. A 1,200-gallon tank can weight as much as 8,000 pounds, so these are not items a homeowner can install on his own.

Can you repair a cement septic tank?

To repair large cracks, your septic repair technician will pump out and clean the tank. They will let it thoroughly dry and then apply concrete crack filler to the cracks. Finally, once cured, then the tank can safely be used again.

How deep should a hole be for a septic tank?

Whatever the case may be, knowing the depth of your septic tank can be a difficult thing given the circumstances, especially if you don’t know where the lids are. The general rule of thumb is that most septic tanks can be buried anywhere from four inches to four feet underground.

How long do cement septic tanks last?

Inspectapedia estimates that a steel tank baffles will rust out in 15 to 20 years and may collapse if driven over, but a concrete tank will last 40 years or more as long as the wastewater is not acidic. It’s important to consider the life expectancy of a drain-field, too.

How much does a 1000 gallon concrete tank cost?

A 1,000-gallon precast concrete tank — adequate for a 3-bedroom home — generally costs $600 to $1,000.

How often should a 1000 gallon septic tank be cleaned?

For example, a 1,000 gallon septic tank, which is used by two people, should be pumped every 5.9 years. If there are eight people using a 1,000-gallon septic tank, it should be pumped every year.

Can you repair the top of a septic tank?

If it is not rusted, you can replace the rusted top with a heavy-duty plastic or concrete lid. Concrete septic tank covers are heavy but strong and durable. Plastic covers offer faster access to the septic tank and are much easier to install.

How do you maintain a concrete septic tank?

Follow these tips to maintain your septic tank system and keep it working properly:

  1. Once you’ve found your septic tank, record the location for future reference.
  2. Have your septic tank inspected regularly.
  3. Pump out your septic tank every three to five years.
  4. Use biodegradable toilet paper that breaks down easily.

How far below the surface is a septic tank?

Septic tanks are typically rectangular in shape and measure approximately 5 feet by 8 feet. In most cases, septic tank components including the lid, are buried between 4 inches and 4 feet underground.

How deep are drain fields buried?

A typical drainfield trench is 18 to 30 inches in depth, with a maximum soil cover over the disposal field of 36 inches.

septic tank connection
Author:tpc1 (TN)I am building a detached garage which has a sink in it.The septic tank is between the house and the garage.I have plumbed a drain line through the brick to drop down and run directly to the septic tank. The drain from the house is on the other side of the septic tank.Is there a hole on all four sides of a septic tank to run a line through?Can I simply drill through the top side wall of the septic tank?How can I connect this drain to my septic tank without going around to the other side? Please help.Any information is greatly appreciated.

Re: septic tank connection
Author:Septic Tank Yank (CO)tpcl,Typically, precast concrete septic tanks have one 4-inch inlet hole and one 4-inch outlet hole.For the installation of this new sink drain to be perfectly correct, you should go ahead and dig the trench that additional 10 feet or so, and then connect the new drain pipe to the 4-inch sewer pipe coming from the house.Cut in a 4-inch wye fitting into the 4-inch sewer pipe and then use the appropriate reduction fittings to accept the new drainpipe.Use a 4-inch Fernco coupling and a close nipple to insert the wye into the existing sewer pipeline.This approach is easier than trying to punch a small hole through the 3 or 4-inch thick concrete sidewall.Depending upon the condition and quality of the concrete in your tank, you may end up making a larger hole than needed.Pounding on the side of the tank with a hammer and chisel or even an impact hammer-drill could collapse the sidewall.If this happens, you will find yourself in “deep do do.”You may have to replace the septic tank.This is a lesson that was learned the hard way.If you decide to punch a hole in the side of the tank to insert the new drainpipe and if your septic tank has two compartments, be sure to locate the new hole so that the water will enter the first compartment of the tank.Good Luck!Post Edited

Re: septic tank connection
Author:Septic Tank Yank (CO)Additional comment:hj is correct regarding the presence of the inlet baffle.Typically, modern concrete tanks are fitted with a 4-inch sanitary tee which acts as the inlet baffle.The importance of the inlet baffle in the performance of the septic tank, however, is a matter of debate.In my view, the only reason to install an inlet baffle is because most septic system regulations require an inlet baffle.I believe that directing the incoming sewage toward the bottom of the tank creates turbulance that resuspends already settled solids and therefor increases the suspended solids concentration in the effluent.If the inlet pipe just enters the tank horizontally above the scum layer, the scum layer dissipates the inrush turbulance and the sewage settles to the bottom of the tank gently.The septic tank that serves my home does not have an inlet baffle, and my system has been performing perfectly for 22 years.I removed the sanitary tee from the inlet pipe just as the health department inspector signed the final inspection line on my permit.He was aware of my action and was interested in knowing the validity, or lack thereof, of the theory.With the advent of septic tank effluent filters, the issue of the importance of the inlet baffle is moot.So if you wish to risk poking another hole into the side of the septic tank and create an additional sewage inlet in the first compartment, go for it.If you wish to comply with the septic system regulation in regard to the inlet baffle, then cement a tee on the end of the inlet pipe and then cement the pipe so that it extends 8 to 10-inches below the liquid level of the tank.Keep in mind that working inside of the septic tank is a nasty and dangerous proposition.

Author:tpc1 (TN)Thank you for all of your responses.I will run my drain around to the other side and connect it to the inlet line.

Re: septic tank connection
Author:hj (AZ)The purpose of the inlet baffle and it does not go down to the bottom of the tank is to create a “no flow” zone above that level. The influent enters the tank through the baffle and the heavier material settles to the bottom, but the lighter materials, i.e., grease and soap float to the top. The “clearer” water layer in the center is what will exit the tank as effluent. It is exactly like a very large grease interceptor, and the largest interceptors are actually a version of a septic tank.

Re: septic tank connection
Author:Septic Tank Yank (CO)hj, tpc1 has stated that he intends to connect his sink drain in the proper manner.Thank you tpc1 for acknowledging our responses and informing us of your intended course of action.I wish to continue our discussion of the importance and purpose of the inlet baffle in a septic tank.The original septic tanks, manufactured in the late 1800’s, mostly were single compartment tanks.Inlet baffles were designed for these tanks to prevent or reduce the potential for short-circuiting untreated sewage through the tank just as you have described.When two compartment tanks became the norm, the need for the inlet baffle became obsolete.The center baffle then provided and greatly expanded the “no flow” zone of which you speak.Single compartment tanks were the norm for many years so the requirement of the inlet baffle was important and was codified in The Manual of Septic Tank Practice, authored by engineers with the US Public Health Service (USPHS) in the 1940’s.Virtually all of the state septic system regulations are based on The USPHS Manual of Septic Tank Practice.When two compartment tanks became the required design, the “need” for the inlet baffle was removed but the “requirement” for the baffle remained in the regulations.I am aware that the bottom of the inlet baffle does not extend to the bottom of the tank, but when low profile tanks are used, the bottom of the inlet baffle is only 24-inches from the bottom of the tank.As the sludge accumulates, this distance slowly becomes diminished.As the sewage from a clothes washer, a dishwasher, a sewage ejector pump, or a modern large volume bathtub/spa flows into the septic tank, it will come into the tank at a greater velocity and volume than the sewage from toilets, showers, and lavatories.If the sewage is directed down toward the bottom of the tank through a 4-inch pipe, the inflow turbulence will resuspend already settled solids that will be carried into the second compartment of the tank, and possibly through the outlet tee of the tank. The suspended solids in the effluent will be applied to the leach field and will increase the formation of the clogging mat.If the leach field consists of a single trench or bed design, the leach field service life is quickly reduced.

Making Septic Tank Access Easier

Because of this, I don’t believe I’ll cut the culvert at an angle in the future. I believe that having a level lid simply looks better! When I initially noticed how near my access lids were to the tank’s exterior walls, I was a little concerned, but it turns out that was by design. The fact that a round riser would not fit exactly against the concrete top of the tank made me understand that a section of the round riser would have to extend out beyond the outer wall of the septic tank, with just earth beneath it, was something I had overlooked.

  1. Sorry, but the tape measurements are a little difficult to read.
  2. This is one of the reasons I’m waiting doing anything as I think about it more thoroughly.
  3. However, I’d forego using the concrete anchor bolts since I’m concerned about damaging the concrete septic tank cover.
  4. As far as I can see, getting rid of the concrete lids has the advantage of requiring far less muscle to remove the plastic riser lid.

For this reason, filling the two holes with shipping popcorn or multiple layers of foam boards cut into 2′ x 2′ squares, and then covering with a decorative large diameter patio paver over each to mark the location and an inch or two of dirt or mulch (just sufficient to cover the foam), with the concrete tank lids still in place, is more appealing to me.

I believe it is intended for the purpose of filling gaps around windows and doors, rather than sealing concrete lids.

I agree with you that rain will not significantly increase the burden.

It is my intention to develop comparable instruments and to measure the scumsludge levels by removing simply the outlet lid (after all, it is closer to grade level and weights a lot less), so that I can determine whether the layers accumulate at the pace that requires my tank to be pumped on a regular basis (almost 6 years for a 1000 gallon tank and a household of 2 people).

  1. In addition, I have a filter on my washing machine that captures the majority of the lint from the machine’s waste water, preventing it from entering the septic tank.
  2. I need to create a compost pile in order to redirect the majority of our organic waste away from the drain; unfortunately, the majority of this garbage does not go down the drain but instead into the trash can.
  3. That had to be snipped out of the roof’s air stack with a snake!
  4. The fact that it was examined is a good thing, otherwise I can only picture the type of plumbing backlog that may have occurred.
  5. You might say that was part of the “new system”: a new tank, along with a new finger system.
  6. My system appears to be functioning normally in the absence of it.
  7. Isn’t it possible that the majority of the toilet paper and other “floaties” would accumulate in the baffle and cause the incoming stream to back up?
  8. Due to the fact that I had identified and dug up both of the pumpers, it only took 45 minutes for them to pump out my tank!

Thank you very much for all of your comments and suggestions! I’ll publish some photos of whatever it is that I decide to undertake ” (“official” riser, culvert and lid, bags of shipping popcorn or layers of 1″ foam board crowned with pretty patio pavers). Regards, Cuz.

How Your Septic System Works

Underground wastewater treatment facilities, known as septic systems, are often employed in rural regions where there are no centralized sewage lines. They clean wastewater from residential plumbing, such as that produced by bathrooms, kitchen drains, and laundry, by combining natural processes with well-established technology. A conventional septic system is comprised of two components: a septic tank and a drainfield, often known as a soil absorption field. It is the septic tank’s job to decompose organic matter and to remove floatable stuff (such as oils and grease) and solids from wastewater.

Alternate treatment systems rely on pumps or gravity to assist septic tank effluent in trickling through a variety of media such as sand, organic matter (e.g., peat and sawdust), constructed wetlands, or other media to remove or neutralize pollutants such as pathogens that cause disease, nitrogen, phosphorus, and other contaminants.

Specifically, this is how a typical conventional septic system works:

  1. All of the water that leaves your home drains down a single main drainage pipe and into a septic tank. An underground, water-tight container, often composed of concrete, fiberglass, or polyethylene, serves as a septic system’s holding tank. Its function is to retain wastewater for a long enough period of time to allow particles to sink to the bottom and form sludge, while oil and grease float to the surface and produce scum. Sludge and scum are prevented from exiting the tank and moving into the drainfield region by compartments and a T-shaped outlet. After that, the liquid wastewater (effluent) exits the tank and flows into the drainfield. The drainfield is a shallow, covered hole dug in unsaturated soil that serves as a drainage system. Porous surfaces are used to release pretreated wastewater because they allow the wastewater to pass through the soil and into the groundwater. In the process of percolating through the soil, wastewater is accepted, treated, and dispersed by the soil, finally discharging into groundwater. Finally, if the drainfield becomes overburdened with too much liquid, it can flood, causing sewage to flow to the ground surface or resulting in toilet backups and sink backups. Finally, wastewater percolates into the soil, where it is naturally removed of harmful coliform bacteria, viruses, and nutrients. Coliform bacteria are a kind of bacteria that may be found in the intestines of humans and other warm-blooded animals, with humans being the most common host. As a result of human fecal contamination, it is a sign of this.

The Guadalupe-Blanco River Authority has built an animated, interactive model of how a residential septic system works, which you can view here.

Do you have a septic system?

It’s possible that you’re already aware that you have a septic system. If you are not sure, here are some tell-tale symptoms that you most likely are:

  • You make use of well water. In your home, the water pipe that brings water into the house does not have a meter. In the case of a water bill or a property tax bill, you will see “$0.00 Sewer Amount Charged.” It is possible that your neighbors have a septic system

How to find your septic system

You can locate your septic system once you have confirmed that you have one by following these steps:

  • Taking a look at the “as constructed” drawing of your house
  • Making a visual inspection of your yard for lids and manhole covers
  • Getting in touch with a septic system service provider for assistance in locating it

Failure symptoms: Mind the signs!

A bad odor is not necessarily the first indicator of a septic system that is failing to work properly. Any of the following signs should prompt you to seek expert assistance:

  • Water backing up into the drains of homes and businesses
  • It is especially noticeable in dry weather that the drainfield grass is bright green and spongy. The presence of standing water or muddy soil near your septic system or in your basement
  • A strong stench emanating from the area surrounding the septic tank and drainfield

Concrete septic tank lid conversion?

I even considered lifting one lid and forming a form around it, then pouring a new one into the form with a pipe nipple already in place. I’m a little concerned about the usage of what you refer to as a “pipe nipple.” That conjures up pictures of a hose fitting tightly or possibly something to which the hose may be attached. I believe it is advisable to provide lots of additional space around the hose. The “honey dipper” always used the extra space available in the suction hose (pump out is a 14″ square hole) to stick a pole into the tank to agitate it and use the hose to spray inside, keeping everything moving so that there was little if any residue left in the tank every time we had our tank pumped (1000 gal with a 250 gallon riser).

Personally, I’d check with the people who do the pump out; they’ll most likely be able to help you, or they’ll be able to recommend someone who can install a gasket and collar with lid for you.

Because you are their consumer and, in all actuality, make their work simpler, this shouldn’t be a significant burden for them to bear. Just my two cents. MikeC

3 Tips to Maintain Your Concrete Septic Tank – Septic Maxx

Septic tanks are available in a variety of shapes and sizes and are constructed of a variety of materials, including cement, steel, and plastic, each of which has its own set of pros and disadvantages. Tanks made of concrete:

  • Possess high effluent concentrations
  • Possess a low likelihood of rising to the surface Are authorized in every state (as opposed to plastic tanks), and are environmentally friendly.

The fact that a majority of Americans choose concrete septic tanks over tanks made of any other material is a testament to these advantages. However, despite all of these advantages, if you have a concrete tank, you should be aware that it is possible for your tank to break under harsh weather conditions. This might result in costly leaks, which would make maintaining a concrete septic tank very difficult. These straightforward suggestions may assist you in maintaining your concrete septic tank and preventing cracks.

Reuse of Concrete Tanks

A long time has passed since concrete septic tanks were employed because of their durability. Despite the fact that they are prone to cracking, many people choose to reuse existing tanks in order to decrease maintenance and installation expenses. Before reusing a concrete tank, it must first be properly evaluated to verify that it is structurally sound and free of defects. Following the examination, the concrete tank must be refitted with a liner that is attached to the interior of the vessel.

It can also help to prevent corrosion, which is a leading cause of septic system failures, which can be quite expensive.

Repair Minor Damages

You should take care of any little damage to your concrete tank as soon as possible. As a result, you may extend the life of your septic tank and avoid minor problems from becoming major problems. The following are examples of typical concrete septic tank damages:

  • Pipe inlets and outlets that have been worn out
  • Baffles that have been damaged

Regular Inspections

The maintenance of a healthy septic system is essential. Pumping and inspecting your septic tank on a regular basis are required to keep it in good condition. Pumping is the process of removing sludge from a tank, whereas inspections are the process of checking the overall operation of the system. Identifying problems early on can save you from having to pay for incredibly expensive repairs later on. The proper maintenance of your septic system might assist to extend the life of your septic tank.

Septic Maxx provides environmentally friendly septic tank solutions that may do this, as well as minimize unpleasant odors and prevent material build-up in the tank.

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

Here are some helpful hints for deciding where to locate your drainfield when you’re designing it.

  • 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

Vehicles should not be allowed on or near the drainfield. Planting trees or anything else with deep roots near the drain field’s bed is not recommended. Clogged pipes are frequently caused by the roots of plants; Downspouts and sump pumps should not be drained into the septic system; and If you want to tamper with or change natural drainage characteristics, do so after researching and evaluating the impact on the drain field. Do not construct extensions on top of the drain field or cover it with concrete, asphalt, or other similar materials.

Easy maintenance and inspection are made possible as a result of this; To aid with evaporation and erosion prevention, plant grass in the soil.

  • 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.
