How Can You Get To Pass The Test Of Septic Tank? (Solved)

  • Perform the actual test – Fill the hole with water to a level 12 inches above the gravel; then time how long it takes for the water to fall to a level 6 inches above the gravel. Some authorities require you to perform this test three times on each hole, and even if yours doesn’t, it’s a good idea to do it anyway.

How do you pass a septic system test?

You can also use these when preparing for the inspection.

  1. Pump septic every 2-3 years as mentioned above.
  2. Inspect around the pump every year for leaks or other issues.
  3. Keep records of maintenance and pumping.
  4. Use low flush toilets, low flow showerheads.
  5. Clean lint regularly from the washing machine.

What does a failed septic dye test look like?

As popular as the septic dye test method is, its usefulness is highly limited. Dye test failures are rare, and when a system does fail, it’s usually already showing signs of leaks or clogs, such as backed up toilets and drains, sewage odors, and standing water around the tank and drain field.

What does a septic dye test show?

Septic Dye Testing is a non-invasive procedure that is used to determine the condition of the components of a home’s waste system. A septic dye test can expose obvious leaks and inadequacies in the system and indicate the need for repairs or alterations.

How do you fail a septic system?

A septic system can also fail due to unseen physical damage to the drain field. While not very common, a septic system can also fail due to broken, or crushed, or clogged pipes in the drain field. This could happen when large vehicles drive over the ground above the drain field, or by large nearby tree roots.

What are signs of septic tank problems?

7 Warning Signs Your Septic System Is Failing

  • Gurgling Pipes. They would occur when you run water in the house (e.g. when using the sink or shower) or flush the toilet.
  • Bad Odours. It’s never a pleasant experience when this occurs.
  • Water At Ground Level.
  • Green Grass.
  • Slow Drainage.
  • Blocked Pipes.

How do I check my septic tanks sludge level?

To measure the sludge layer:

  1. Slowly lower the tube into the septic tank until it touches the bottom of the tank.
  2. As the device is slowly pulled out of the water, the check valve closes capturing a liquid/solid profile of the septic tank water. The thickness of the sludge layer can be measured.

Why would a dye test fail?

Should the water in the sanitary sewer be the dyed color you used, then you’ve failed the test. A failed dyed test means you cannot sell your home. Before you can sell your home, you need to have the outside drainage line re-located so it is properly connected to the combined sewer.

How long is a dye test good for?

An approved dye test is good for three years. Refinancing does not require a dye test.

How long does a home dye test take?

DYE TESTING The test takes approximately one hour and can detect a slew of concerns.

How do you test a septic drain field?

In order to test the overall health and liquid capacity for your leach field, it is necessary to perform a hydraulic load test. This is done by running water at a certain rate over an allotted period of time. A failure occurs when water back-drains to the source before that allotted time period is up.

How much water is used in a septic dye test?

Volume of Liquid Septic Dye to Use: 1.6 oz (liquid) per 1,000 gallons of septic tank volume.

How long does it take to get dye test results?

If a dye test is needed, the timeline is dependent upon multiple factors. PWSA will reply to the Dye Testing Results Form within 10 business days of receipt as well. In other words, this time period will be longer if the property requires a dye test or corrective actions.

What is the most common cause of septic system failure?

Most septic systems fail because of inappropriate design or poor maintenance. Some soil-based systems (those with a drain field) are installed at sites with inadequate or inappropriate soils, excessive slopes, or high ground water tables.

How do you tell if the leach field is clogged?

Stay vigilant for five signs your drainfield does not drain correctly anymore.

  1. Slowing Drainage. Homeowners first notice slower than usual drainage from all the sinks, tubs, and toilets in a home when they have a compromised drainfield.
  2. Rising Water.
  3. Increasing Plant Growth.
  4. Returning Flow.
  5. Developing Odors.

How do I know if my drain field is failing?

The following are a few common signs of leach field failure:

  1. Grass over leach field is greener than the rest of the yard.
  2. The surrounding area is wet, mushy, or even has standing water.
  3. Sewage odors around drains, tank, or leach field.
  4. Slow running drains or backed up plumbing.

How to Get a Septic System to Pass Inspection: A Complete Guide

It is recommended that you engage a professional to examine your tank in order to get an accurate reading; but, if you are comfortable doing it yourself, you may save money by using this technique. It is also possible to save money by reducing the amount of accumulation in your tank and extending the intervals between pumping sessions with the help of Septic Maxx.

Need A Septic Service Provider To Help Repair or Replace Your Failed Septic System?

It goes without saying that every one of your prospective purchasers will want to make sure that everything is up to code. It is critical to verify that your septic tank has been totally drained and cleaned thoroughly so that all poisonous and hazardous materials have been removed and that the waste has been allowed to cycle properly in order to be prepared for a Title Five inspection. Preserve in mind the following aspects that are often and completely examined throughout an aseptic inspection: Sludge.

If this thick layer is not taken out by frequent pumping and is allowed to develop to dangerous levels, it has the potential to create a major problem for the entire system.

When fats, oils, and grease enter your septic tank, they float to the top, forming a lighter layer known as scum that collects on the surface.

Flow.

The smallest interruption to the regular flow mechanisms inside your tank can result in backups or blockages, which can cause significant damage to your pipes and plumbing systems.

  1. Put an end to the use of any bleach products or other harsh chemicals. In the process of cleaning your sinks, tubs, and toilets with such items, you might be eliminating beneficial microorganisms from your septic tank. In order for waste stuff to be digested effectively, this bacterium is very necessary. The effective decomposition of waste within your septic tank helps considerably to the prevention of difficult obstructions and back-ups in the plumbing system of your house. Furthermore, bleach can harm the cement framework of your septic tank and can gouge holes into the tank’s structure over time, depending on how often you use it. Because of the structural damage, you may have to replace the complete tank. Initiate the use of all-natural cleaning solutions, especially when you anticipate an inspection by the local regulatory agency for your septic system.
  • Avoid overloading your system with excessive water consumption. In order to ensure that your septic system is correctly emptying into the drainfield, your Title 5 Inspector will likely flow water through it. As a result, it is critical that you do not overload your system with excessive water, especially within a week or two of your scheduled inspection. High levels of water in your drainfield will hinder the inspector’s test water from properly absorbing, which will result in a failed inspection in the end. This can be accomplished by reducing the number of laundry loads each week or spreading them out across many days. Overburdening your septic system with a large amount of laundry at one time might result in clogged drains and other problems. Neither your septic system nor your Title 5 inspection will benefit from this situation.
  • Leaks in your plumbing should be addressed as soon as possible. Even the smallest, apparently insignificant leaks may accumulate and become an expensive problem over time.
  • Use your waste disposal device as little as possible. A septic system is not intended to break down food that has been disposed of through a waste disposal unit. If you are unable to avoid purchasing a waste disposal unit, be sure that the equipment does not discharge into your septic tank by following the manufacturer’s instructions. Garbage disposal machines generate garbage that might be overwhelming to your septic system, resulting in drain obstructions practically all of the time.
  • Pay close attention to your surroundings. Maintain as much distance as possible between your septic system and trees or vegetation. It is another typical problem that you would like to prevent with your septic tank system, which is the penetration of tree roots into the system itself. Naturally, tree roots are attracted to the high concentrations of nutrients and wet waste found in septic tanks and sewer lines. When tree roots progressively encroach on and into your septic tanks and pipes, the roots can encroach on little leaks and cracks, eventually worsening the leaks and cracks as time goes on. If tree roots do become entangled in a pipe, a machine can be used to chop the roots out of the pipe. The problem is that if you don’t get the tree removed, your pipes will ultimately become stuck again
  • Make a schedule for routine septic pumping and stick to it. Have your tank pumped every 3 to 5 years to keep it running well. Even though draining out your septic system is not a requirement of the Title 5 Inspection process, doing so will help to ensure a smooth and successful inspection procedure. A clean septic tank is considerably easier to check since it eliminates any “proof” of any indicators of abuse that may have occurred (like non-septic safe items or substances). The simple rule of thumb is that nothing that cannot be organically broken down or digested should ever make its way into a septic tank and be visible to your inspection. or at any point in the future

Other Points to Keep in Mind Before Getting a Septic Inspection

Check: For:
Conventional Systems
ü Date of last pump out Sludge level. Sludge accumulates on the tank’s bottom and should not occupy more than 1/3 of the tank’s total volume or rise to the level of the baffles.
ü Septic tank and drainfield location Ample distance from wells, streams, and other water sources. Water lines should be at least 10 feet from all components of the septic system.
ü Tank Size Sufficient capacity. Ensure that your septic tank is large enough for the facility that it serves. A four-bedroom home, for example, typically needs a 1,200-gallon tank. The more occupants, the larger the tank required.
ü Ground Surface Liquid waste that may have seeped out. This indicates that your system is overloaded. Ensure that your tank is watertight so wastewater does not contaminate your groundwater, and groundwater does not flow into the tank, causing it to overfill.
ü Riser Lids Cracks or breakage. Ensure that these are securely placed.
ü Baffles Any signs of damage or displacement. Ensure that these are securely connected to tank’s inlet and outlet pipes.
ü Drain Lines Even flow. Drain lines should each receive the consistent volumes of wastewater. Check your distribution box. If the box becomes tipped or clogged, it will allocate effluent disproportionately, potentially flooding sections of your drainfield.

If you are the party who is purchasing a piece of real estate, the same due diligence requirements apply. You never really know what the previous residents of the property have flushed down the toilet or what may be in the septic tank until you open the door to the property. If you are a prospective buyer, it is in your best interests to urge that the septic system be tested before any acquisition is closed, particularly if it has not been done lately. In addition, even if you are the sole owner of the property and have no plans to sell it, your septic system should be tested at least once a year.

A successfully completed Title Five Inspection will only increase the value of your property while also assisting you in avoiding any liability concerns that may arise as a consequence of a malfunctioning septic system.

What Happens During a Septic Inspection?

If you own a property that is serviced by a septic tank system, it is critical that you keep up with the necessary septic tank maintenance on a consistent basis. You should also arrange a septic tank check as soon as you see any indicators of a problem with your septic tank to ensure that the problem is properly diagnosed. Any problems with your system’s operation should be discovered and diagnosed by your contracted septic expert during the course of a septic inspection. A competent septic tank care firm should be able to give you with a complete range of inspection and repair services, as well as a variety of other services.

  • Consultation.
  • When your septic inspector arrives, one of the first things he or she will do is speak with you to learn more about your septic system’s maintenance history as well as any present problems you may have seen.
  • Inspection by sight only.
  • Mirrors and cameras, among other instruments, will be used by the inspection professional to obtain a visual of the inside of the septic tank and filter system.
  • Drainage Field Examination Immediately following the completion of the visual examination, the drainfield test will be performed as the next part of the septic system inspection.

Upon inspection, if it is discovered that the holes contain standing water, this is a sign that the septic system need maintenance or repair. A septic system check might assist you in identifying a minor problem before it becomes a costly one to deal with.

How Much Does a Septic Inspection Cost?

It is critical to be aware of when it is necessary to have your septic tank drained out. Wastewater collected and processed in septic tanks contains both solid and liquid wastes, and the effluent is discharged into a drainfield once it has been processed. Solid wastes accumulate in the tank over time and must be pushed out to prevent it from becoming clogged. It is possible that if the solid debris in the tank is not removed, it will be driven out of the tank and block the drainfield, causing it to malfunction.

  • The cost of having your septic system tested can range from $100 to $250, depending on the location of your home or business.
  • (more, if service charge is by the gallon).
  • You may either do it yourself or pay the pumper to do it for you, which is the more recommended option.
  • However, on any given day, these are still significantly better sums as compared to the expense of having to repair your drainfield, which may range from $2,500 to $10,000.

Are Septic Inspections Necessary?

Even though they are not necessary, septic inspections are highly recommended. In the event that you are a buyer or renter in the market for an apartment or a house, you will want to examine and ensure that the toilets flush properly and that the drains are properly clogged. As a renter, you are unlikely to be concerned about the septic tank; but, as a homeowner, you will own both the property and the septic tank beneath it, which means that you will be totally liable for anything that occurs on the grounds.

  • Final say on whether you should have your septic system checked is ultimately up to you, but there are a few variables to consider before making that decision.
  • But it’s always a good idea to have your septic system checked out even if everything else checks out fine.
  • Simply said, even though a septic system looks to be in good working order, it is necessary to have it examined on a regular basis.
  • Although, on average, every three to five years is a healthy interval between pumping.
  • Septic systems require periodic monitoring and maintenance to ensure that they are operating correctly and that they will never constitute a health or environmental danger to the public or the environment as a result of contaminants in the wastewater and groundwater from the property.
  • Sewage can back up into your facility or surface to your groundsoil when the capacity of your septic system or soil absorption field exceeds its maximum capacity.

If all of the information presented thus far hasn’t convinced you that you should have your septic system inspected, consider the following: Furthermore, failed septic systems can diminish the value of your home and potentially increase the likelihood of a lawsuit against you in the future.

Septic Questions to Ask When Buying a Property

Keep in mind that if you’re in the market for a new house or commercial property and you’re visiting a facility, you should bring up the topic of the septic tank. You’d be wise to inquire:

  1. Whether or not it has been properly maintained throughout time
  2. Whether or not the septic tank has been properly inspected by a professional
  3. Whether or not the current septic system has recently been subjected to an open pit test

While you’re walking around the outside grounds of the property you’re contemplating, keep an eye out for any strange odors that could be in the air. Do not be afraid to question about anything that smells odd if you come across something unusual. Also keep an eye out for any areas of grass or plants that appear to be greener or more lush than the rest of the area. If water collects exactly above the ground where your septic tank is located, this might be an indicator of sewage leaks, which can be a major issue.

  • It is both your right and your obligation to do so.
  • Septic systems are designed to collect, treat, and dispose of wastewater and solid waste generated by a home’s or establishment’s plumbing system, to summarize.
  • Effluent is discharged from the tank on a regular basis and flows into a drainfield, where it is naturally filtered by bacteria before being reintroduced into the groundwater.
  • As previously said, septic system checks should be conducted once a year to verify that the system is operating properly.
  • For a list of local septic service providers, please see our State Directory.

The Guidebook to Passing a Septic System Inspection

Not everyone realizes how critical their septic system is until something goes wrong and they require professional assistance to repair it. Many people are also ignorant that when it comes to septic systems in Florida, there are certain regulations and laws that must be adhered to. It is critical to adhere to these standards and guidelines in order to pass inspection. Brownie’s SepticPlumbing is fully aware of the restrictions that apply to our industry. We make it a point to educate homeowners and business owners on the regulations they must follow in order to guarantee that their septic systems pass inspection.

Installing a New Septic System

The law requires that any individual or firm that wishes to do any type of work on a septic system be registered and approved by the state. This indicates that the training has been completed and that licensed persons can have their registration renewed on an annual basis if they choose.

Anyone planning to begin work must file an application to the Department of Health before they may get started. Any needed fees, soil/percolation testing, and sit plans must be included with the application, as well as all other applicable standards and documentation.

What Gets Inspected

While following all applicable rules for septic tank location, licensing, and other aspects of the system might be beneficial, the inspection will place a strong emphasis on the tank itself and the overall effectiveness of the system. This entails ensuring that the septic tank is in excellent working order in order to safeguard the home and its plumbing. When purchasing a property, potential buyers will want to know that everything is in working order, therefore inspections are often done during the buying process.

Some items that are frequently checked are listed below.

This is a dense lawyer who may become a significant problem if there is an excessive quantity of sludge in the system.

A properly functioning septic tank will avoid any backups or obstructions that might cause harm to the pipes and plumbing systems in the home.

Why Inspection Is Important

What the former owner of a property flushed down the toilet and what may be in the septic tank are things that can never be known for certain. It is critical to guarantee that the septic tank is thoroughly drained and cleaned in order to ensure that any potentially hazardous particles are removed and that the waste may flow freely.

Perc Testing and Soil Testing – What You Need to Know

This Article Discusses If you don’t have a perc, you don’t have a house. Test with a Deep Hole Testing with Percs SetbacksClearances Alternatives in the Event of a Site Failure View and post commentsQuestions Septic System Frequently Asked Questions SEPTIC SYSTEM articles can be found here. Traditional septic systems can only function well if the soil in the leach field region is sufficiently porous to allow the liquid effluent flowing into it to be readily absorbed by the soil. A failure to do so will result in untreated wastewater backing up and pooling on the surface.

  • It is in this soil layer that the majority of the treatment takes place.
  • This happens less frequently.
  • Depending on the municipality, particular criteria may differ, however any of these qualities may exclude the installation of a basic gravity-fed septic system.
  • A percolation test (often referred to as a “perc test” or “perk test”) is necessary to assess if a construction site is appropriate for a septic system installation.

NO PERC, NO HOUSE

A failed perc test on a rural site without municipal sewage services implies that no home may be built, which is why you should make any offer to acquire property contingent on the site passing both the soil and the perc tests before proceeding with the purchase. Percolation or perc tests are becoming increasingly popular in rural areas as prime building sites become increasingly uncommon (or prohibitively costly) in many sections of the country. Rural sites that do not pass the percolation or perc test are becoming increasingly common.

  • Soils are often classified as either coarse sand and gravel particles or microscopic silt particles, with minuscule clay particles — the tiniest – making up the majority of their composition.
  • Before investing time and money in testing, dig down to the lighter soil beneath the first few inches of topsoil (loam) and get a handful of it to have a good notion of what you’re dealing with.
  • It shows that the soil has a high clay content and that it may fail a typical perc test if you are able to construct a ribbon of dirt 2 inches or longer in the ribbon test.
  • Testing requirements differ significantly from state to state and frequently from town to town, since most governments let small municipalities to develop their own laws within the framework of state regulations.

a. Though not all of these tests require the services of a certified professional, it’s a good idea to engage a seasoned expert with extensive local knowledge because many of these tests have some wiggle space.

DEEP HOLE TEST

The majority of studies begin with a deep hole test that is excavated by machine to a depth that is considerably below the bottom of the planned leach field – often 7 to 10 feet deep or more. High water tables, as well as the presence of rock ledges or impermeable soil that will prevent water from being absorbed, are sought for by the testers. In certain regions, testers are also looking for drainage features in the soil. It may not be necessary to carry soil samples back to the lab; instead, visual observations of the soil strata may be adequate.

  • It requires a trained eye to spot soil mottling, which is a sign of a seasonal high water table – at a depth of about 2 feet here, the water table is around 2 feet deep.
  • Actual observations are utilized to determine the “limiting zone,” which is the area of soil where the soil is unsuitable for sewage treatment.
  • The existence of a seasonal high water table may be visually determined by checking for “mottling,” which are splotches or streaks of color in the soil that indicate the presence of water on occasion.
  • For situations when the limiting zone is too close to the surface to be accommodated by a normal leach field, a mound or other alternate septic system may be necessary.
  • However, while the vast majority of soil specialists think that soil observation may offer sufficient information for the design of a functional septic system, most states now mandate perc testing to directly quantify the rate at which water percolates through the soil (perc testing).
  • The results indicate whether or not a septic system can be implemented in a given community, and the results are used by system designers to calculate the size of the leach field.

SEASONAL HIGH WATER TABLE

Under specific situations, certain towns may additionally require direct testing of the seasonal high water table to be performed. For example, this may be necessary for some types of alternative energy systems or in places where the water table is known to be high. The most common method is to dig tiny monitoring wells, which are also known as piezometers. The monitoring wells are simply plastic pipes that are screwed into holes that have been dug into the earth.

Water is monitored in the pipes during the wettest time of the year, which is between June and September. It is necessary to have appropriate clearance between the bottom of the drain field trenches and groundwater in order for a system to be certified by the city.

PERC TESTING

To conduct a perc test, first consult with a representative from the local health department. Requirements can differ significantly from town to town in terms of who can conduct the test, the minimum number of holes, the depth of the holes, the required absorption rates, and the time period during which the tests can be conducted. In general, tests cannot be performed in frozen or disturbed soil, and some regions only allow tests to be performed during specific months of the year – so prepare ahead of time.

  • If the test fails, you may be forced to invest in a more expensive alternative technology, or the site may be deemed unusable.
  • A typical perc test consists of two or more holes drilled around 30 to 40 feet apart in the planned drain field region, with the holes being approximately 30 to 40 feet apart (see illustration).
  • After that, either you or the technician should fill the bottom of the hole with 2 inches of clean gravel.
  • Remove any loose soil from the bottom of the hole with a sharp tool as well.
  • Continue to add water until there is approximately 12 inches of water in the hole for at least 4 hours.
  • The next day, carefully wipe away any loose dirt that has fallen to the bottom of the holes and gently fill each hole with water to a depth of 6 inches over the level of the gravel in each hole.
  • The timings are then meticulously recorded and used to compute the percolation rate, which is the amount of time it takes for one inch of water to descend into the ground.
  • When using a normal gravity-flow septic system, a 60-minutes per inch (MPI) rate is commonly used as the cutoff point, indicating that the water dropped one inch in 60 minutes.
  • Some municipalities demand extra “hydraulic” soil testing for locations that test higher than 30 minutes per inch in some instances.
  • Water absorbs too quickly below that level to be efficiently treated before it reaches the groundwater table.

The hole with the weakest performance is the one that matters. The presence of a town official to witness the test is required in certain communities. Perc test regulations differ significantly from one municipality to the next. The following are some general ranges for soil permeability:

  • Lower than 5 MPI: Extremely porous soil. Alternative systems, such as pre-treatment of effluent, pressured dosing, or the addition of denser soil surrounding trenches, may be permitted. A conventional leach field with a flow rate of 5 to 60 MPI is authorized. 60 – 120 MPI: Soil with a low water-holding capacity. Alternative systems, such as pre-treatment of effluent, pressurized dosing, improved treatment, mound systems, and other alternative systems, may be permitted. When the MPI is more than 120, the soil is said to be very low-permeable. It may be possible to use alternative technologies that provide improved wastewater treatment under certain situations.

In most circumstances, test findings are valid for two to five years, and in some cases they can be extended. However, like with all things perc, rules vary significantly from town to town, so don’t make any assumptions about what to expect. Always check with the local health department before embarking on a project.

OTHER SITE CONDITIONS

Septic system rules vary greatly from municipality to municipality, although the majority of municipalities demand that the leach field satisfy specified specifications in addition to passing the perc test. Some of the most typical stumbling blocks are as follows:

  • Slope with a lot of incline. Typically, the maximum permitted slope for a conventional system varies between 20 and 30 percent
  • Filled land Most of the time, native soils are necessary, while manufactured fill may be acceptable in rare instances. Wetlands and floodplains are two terms that are used to describe the same thing. This is not suitable for the leach field. Site drainage is important. During rain storms, the leach field should not be in the path of runoff, which might result in system erosion or flooding.

SETBACKSCLEARANCES

It is necessary to maintain a minimum distance between the septic tank and leach field and any structures, property lines, water pipelines, wells, or bodies of open water. In the case of tiny locations, a variance may be necessary in order to provide adequate space. It is possible that you will be required to find adequate area for both the current leach field and a replacement field, which will be used in 20 or 30 years after the original field has been depleted of its capacity. The number of clearances varies from one town to the next.

SEPTIC SYSTEM MIN. CLEARANCES (typ.)
Distance to Septic Tank Leach Field
House 10 ft. 10-20 ft.
Property line 10 ft. 10 ft.
Private well 50 ft. 50-100 ft.
Potable water piping 10-25 ft. 25 ft.
Open water(stream,pond, wetland, etc.) 50-100 ft. 100 ft.
Dry gulch/stream bed 10 ft. 25 ft.
Subsoil drains 10 ft. 25 ft.
Note:Always check with local codes

OPTIONS IF SITE FAILS

Even if your site fails a perc or deep-hole test, it is not always doomed to failure. It may be possible to “de-water” the drain-field area on sites with high water tables by strategically constructing gravel-filled trenches and subsurface drain pipes to divert water away from the drain-field region. To complete this project, you’ll need the services of a highly skilled earthwork contractor, as well as the assistance of a civil engineer or geotechnical engineer. Additionally, in recent years, a diverse range of alternative septic systems have been created for use on a variety of different types of sites.

  1. In general, these systems are more expensive, and many of them require additional components such as pumps, alarms, and other devices that necessitate more monitoring and maintenance than a normal sewage system.
  2. Building lots that were formerly considered unbuildable may become authorized building lots when alternative solutions become more prevalent and broadly recognized.
  3. Look for a contractor that has previous expertise installing the precise system you are considering as a second option.
  4. A clogged septic system is not a pleasant sight or scent to see.
  5. In order to do a perc test, who should I hire?

Perc Testing and What to Do If The Site Fails

It is only if the soil in the leach area is sufficiently porous that it can quickly absorb the liquid effluent flowing into it that traditional septic systems will function properly. There must also be at least a few feet of decent soil between the bottom of the leach pipes and the rock or impermeable hardpan below, or between the bottom of the leach pipes and the water table. A site can also fail because the soil is excessively porous, enabling the effluent to reach the groundwater before it has had a chance to be thoroughly treated.

Slopes that are too steep for a typical leach field are likewise inappropriate for them.

In rare instances, an alternate septic system that is more expensive may be permitted.

NO PERC, NO HOUSE

It is only if the soil in the leach area is sufficiently porous that it can quickly absorb the liquid effluent flowing into it that traditional septic systems will function well. There must also be at least a few feet of excellent soil between the bottom of the leach pipes and the rock or impermeable hardpan below, or to the water table, in order for the leach pipes to function properly. A site can also fail because the soil is excessively porous, enabling the effluent to reach the groundwater before it has had a chance to be thoroughly treated.

The use of a typical leach field is likewise not recommended on extremely steep slopes, as previously stated.

It may be possible to install a more expensive alternative septic system in some circumstances.

DEEP HOLE TEST

The majority of studies begin with a deep hole test that is excavated by machine to a depth that is considerably below the bottom of the planned leach field – often 7 to 10 feet deep or more. It may not be necessary to carry soil samples back to the lab; instead, visual observations of the soil strata may be adequate. In order to determine the drainage properties of the soil, the presence of a seasonal high water table, and the depth of the “limiting zone,” which is the area where the soil is unsuitable for sewage treatment, soil tests or observations are conducted.

The higher layer of the water table, as well as impermeable rock or soil, form the limiting zone of a body of water.

Typically, the water table or impermeable soil in the leach field must be at least 3 feet below the bottom of the trenches in order for the leach field to be effective.

The speed at which water drains into a standard-sized hole in the ground is measured by this test. The results indicate whether or not a septic system can be implemented in a given community, and the results are used by system designers to calculate the size of the leach field.

PERC TESTING

To conduct a perc test, first consult with a representative from the local health department. Requirements can differ significantly from town to town in terms of who can conduct the test, the minimum number of holes, the depth of the holes, the required absorption rates, and the time period during which the tests can be conducted. In general, tests cannot be performed in frozen or disturbed soil, and some regions only allow tests to be performed during specific months of the year – so prepare ahead of time.

However, like with all things perc, rules vary significantly from town to town, so don’t make any assumptions about what to expect.

Septic system rules vary greatly from municipality to municipality, although the majority of municipalities demand that the leach field satisfy specified specifications in addition to passing the perc test. Some of the most typical stumbling blocks are as follows:

  • Slope with a lot of incline. Typically, the maximum permitted slope for a conventional system varies between 20 and 30 percent
  • Filled land Most of the time, native soils are necessary, while manufactured fill may be acceptable in rare instances. Wetlands and floodplains are two terms that are used to describe the same thing. This is not suitable for the leach field. Site drainage is important. During rain storms, the leach field should not be in the path of runoff, which might result in system erosion or flooding.

SETBACKSCLEARANCES

It is necessary to maintain a minimum distance between the septic tank and leach field and any structures, property lines, water pipelines, wells, or bodies of open water. In the case of tiny locations, a variance may be necessary in order to provide adequate space. It is possible that you will be required to find adequate area for both the current leach field and a replacement field, which will be used in 20 or 30 years after the original field has been depleted of its capacity. Clearances differ from one municipality to the next, so always verify with local codes.

OPTIONS IF SITE FAILS

Even if your site fails a perc or deep-hole test, it is not always doomed to failure. It may be possible to “de-water” the leaching region on locations with high water tables by strategically constructing gravel-filled trenches and subsurface drain pipe to direct water away from the leaching area. To complete this project, you’ll need the services of a highly skilled earthwork contractor, as well as the assistance of a civil engineer or geotechnical engineer. A broad variety of alternative septic systems have also been created in recent years for usage on a wide variety of different types of land.

In general, these systems are more expensive, and many of them require additional components such as pumps, alarms, and other devices that necessitate more monitoring and maintenance than a normal septic system.

When it comes to modern building technology, though, it’s important to seek for items and systems that have a proven track record on the job. Morse Engineering and Construction can be contacted for additional information. Source:buildingadvisor.com

All About the Percolation Test Required for a New Septic Tank

Septic systems enable you to construct a house or business on even the most distant of lands that are not already served by a sewer system. A septic tank’s suitability for a particular property, on the other hand, requires more than simply the owner’s willingness to spend the money to install one. Prior to granting approval for a permit for the installation of the system, your county will need that you do a percolation test, which is also known as a perc test. Learn everything you can about this test before it is conducted so that you are well prepared for the procedure.

  • A percolation test determines how well the earth drains in a specific area of a building’s foundation.
  • It may be necessary to conduct a number of percolation tests before determining the best site for a septic tank.
  • What is the procedure for testing percolation?
  • It is necessary to dig a hole of specific depth and fill it with water before measuring how long it takes for the water to completely drain into the surrounding soil in each test.
  • The soil’s water absorption rate will not be reliably measured if the holes are too small.
  • Contractors often dig at least two pits at opposing ends of the intended drainage system to ensure that the entire region drains at an appropriate rate during the project.
  • The majority of percolation tests are performed prior to the construction of a new septic tank.

In certain situations, relocating a system necessitates the performance of a percolation test as well, as the new location may have different soil drainage characteristics.

If you want to save money and learn more about your property’s drainage system before paying for any expert maintenance, you may dig your own percolation test pit.

If you decide to dig your own pit, make sure to slope all of the sides to both prevent the surrounding earth from collapsing and to allow you to escape if you do fall into the pit.

It is safer to slope all four sides of the task while doing it by hand with a shovel rather than using a machine.

If you fail a percolation test, you will be unable to construct a typical septic tank in the region where the test was conducted.

We at Walters Environmental Services invite you to schedule a professional percolation test with us now to determine whether your site is suitable for the installation of a septic system.

How to Do a Perk Test for Septic Tanks

Performing a soil percolation test will be required if you’re going to build a new septic system in accordance with local regulations. Depending on your jurisdiction, you may be able to do the exam yourself, but in certain cases (including some sections of California), you may need to hire a certified professional to perform the test. The percolation rate of the soil is determined in minutes per inch, and as long as it is within the limitations set by the local health authority, the test may be used to establish the size of the drain field that is necessary.

  • It is possible for groundwater to get contaminated if the soil is sandy and drains too rapidly.
  • However, if the soil contains a high concentration of clay and drains too slowly, raw sewage water will linger near the top and may pool there.
  • The majority of the time, it takes two days to complete a perk test.
  • Furthermore, you should never do a perk test on soil that is frozen or frosty.

The Basic Idea Behind a Soil Percolation Test

The length of time it takes for water to drain is measured by a perk test. Pouring water over the earth would not be sufficient to determine this; thus, holes must be dug to collect the water. The majority of countries need more than one hole, with a minimum amount of space between each one. Keep in mind that the greater the number of holes you dig, the more accurate the test will be. This is especially true if the soil qualities vary greatly over the region of the planned drain field. After the holes have been excavated, scrape the sidewalls of the holes to remove any soil that has been compacted by the digging tool; then, pour gravel into the bottom of the hole to fill it.

Some governments in locations with damp soil demand deeper holes to be dug using a backhoe, which must be done by hand.

If you live in an area where smaller holes are needed, the size and number of holes you dig, how deep you cover the bottom of the hole with gravel, and how long you let the soil to absorb water are all limited by local regulation.

A General Procedure for Conducting a Perk Test

When digging the holes by hand, you’ll need a post-hole digger, a source of water, a timer, and a mechanism for properly measuring the depth of water in each hole starting at the top of each hole.

In addition to using a long ruler to measure with, you may also tie a little hollow ball to a rope and use it as a float to be more precise. You may attach the string to a pulley system and move the string up and down the length of a ruler while following a marking on the string.

  • Excavate the test holes – Most jurisdictions require the test holes to be 4 to 6 inches in diameter and sunk to a depth ranging from 18 to 36 inches. It is necessary to have at least two holes, but it is preferable to have more. When evaluating a plot for a prospective drain field, you should position the holes at a distance of more than 50 feet apart.
  • Make the test holes in advance– Scrape down the sidewalls of the holes with a knife or other pointed tool to create a natural interface for the water to seep through to the bottoms. Remove any debris from the hole and then fill it with 2 to 6 inches of gravel to form the bottom. If possible, line each hole with mesh to prevent soil from sliding down the edges of the hole and into the bottom of the hole. A perforated drainpipe is recommended by some contractors to be inserted into each hole to prevent dirt from falling through.
  • Prepare the soil by filling each hole with water and covering it with a lid, and then keeping it full for four hours. After you have completed this step, you must wait 18 hours before conducting the actual test. That means you’ll have to wait until the next day, so make sure you cover the holes overnight.
  • Carry out the real examination – Water should be filled into the hole to a level 12 inches above the gravel. Then, you should time how long it takes for the water level to drop to a level 6 inches above the gravel. Some authorities require you to repeat this test three times on each hole, and even if yours does not, it’s a good idea to do so as a precautionary measure anyway. Because of this, outcomes are more dependable.
  • It is a good idea to keep track of your results in a table with headers for the hole number, the depth of water when you started, and the depth of water when you finished your round. For each row of the table, the reading is represented by a different letter.

Interpreting the Test Results

You’ll need to translate each result to minutes per inch, which you can accomplish by dividing the number of minutes it took for the water level to drop 6 inches by the number of minutes it took for the water level to drop 6 inches. Please keep in mind that if it takes more than 6 hours for the water level to drop by this amount in any hole, the location is not ideal for a septic drain field, and you should terminate the test right then. If you dig less than five test holes, the percolation rate with the slowest percolation is the one you state on the septic permit application, even if you dig more.

Consider the following percolation rates, which you would want to keep track of:

  • 24.7 minutes per inch
  • 20.5 minutes per inch
  • 32.4 minutes per inch
  • 31.3 minutes per inch
  • 40.5 minutes per inch

There is an average percolation rate of 30 minutes per inch of depth, which is substantially greater than the lowest rate, which would be required to be reported if you just dug two holes. A higher percolation rate may allow for the installation of a bigger septic system.

Is the Site Suitable for a Septic Drain Field?

It is only one of the parameters that determines whether a site is appropriate for a drain field that soil percolation is measured. It is necessary to consider the height of the site, its placement relative to rivers, and the slope of the ground while calculating the equations.

  • Sites that are higher in elevation than the septic tank are typically inappropriate unless there is a significant amount of separation between the site and the tank itself. Choosing such a location will need the installation of a transfer pump in the tank.
  • It is not permitted to site drain fields in close proximity to wells, streams, or other waterways, although the exact distance between them is usually decided by the local health inspector.
  • In addition to the danger of roots infiltrating the leach field pipes, densely wooded locations are undesirable for this use.
  • Rocky terrain, as well as low-lying marshy places, are clearly inappropriate for this purpose.
  • Septic fields should not be built on steeply sloping terrain, especially if the area slopes toward a canal or an adjacent property
  • Instead, they should be built on flat land.

There are options available if your building site does not have a plot of ground appropriate for use as a septic drain field, including having a drainage system designed. You may also think about installing a sewage lagoon, in which the outflow from the septic tank is held above ground and cycled and aerated by a pump to keep the water clean. The use of this method may be appropriate in a rural, wooded environment with a high concentration of steep gradients and streams.
