InspectAPedia does not allow any form of conflict of interest. The sponsors, goods, and services described on this website are not affiliated with us in any way. Equipment for finding septic tanks: A septic tank may be located with the use of several basic instruments and technologies, which are described in this paper. This article explains how to locate a septic tank when the position of the tank is not previously known or when the location of the septic tank is not readily apparent from the surrounding area.

ToolsEquipmentto Find theSeptic Tank

The following section discusses sewage tank finding tools and equipment. If you have not already done so, please read our more basic method to locating your septic tank by visual inspection: SEPTIC TANK, HOW TO FIND. Remember to use caution while probing or excavating a septic tank, drywell, or cesspool, especially if you are not convinced that the installation has a safe and secure cover. Probing or excavating over a failing septic tank or cesspool, or even drywall, can cause the system to collapse, which is potentially lethal.

Some inspectors or septic service firms use a basic septic tank finding probesuch, instrument as a 1/4″ steel rod or a heavier steel wrecking bar, to probe the earth around a suspected septic tank site. Keep an eye out for: An oversized wrecking bar driven into the ground can perforate a steel septic tank lid or shatter a terra cotta septic drain line
OrORANGEBURG PIPEseptic drain line. These approaches, on the other hand, can be beneficial if applied with caution in soft or moist soils. A wrecking bar was used in a similar septic application, the inspection of septic fields, to make holes in a drainfield, but not directly across a drain line, in order to examine soil conditions. A failed septic system may cause wastewater to rise to the surface through an opening of this nature.)

Using a shovel is a low-tech and high-sweat technique of locating any buried thing, provided that you have a basic concept of where the object is hidden. Our contractor utilized a backhoe to “discover” the sewage tank when we conducted our first septic tank search in 1969. He “discovered” it by driving over and collapsing an old steel septic tank, which he had been looking for. I wished we’d begun with a shovel a little more slowly
Using a metal detector, you may locate certain septic tanks that have steel tank tops or manhole covers that have been utilized to cover the entry port to the tank. Drain Pipe with Electronics To locate the septic tank, use your senses: The septic tank may be pinpointed with pinpoint accuracy using technological means: Some plumbing contractors can locate the precise position of the septic tank at this stage by inserting a special plumbing snake into the main home drain pipe and running it through the house. In either case, the plumbing snake is placed into the drain line from a suitable point and then stretched until it encounters an impediment, which might be an obstruction in the drain line or it could be that the snake has extended into the septic tank and struck it. The metal plumbing snake receives an electrical signal that is supplied into it. The signal from the plumbing snake may be detected by a receiver located outside. The precise course of the snake in the underground drain line may be traced all the way to the tank by passing the receiver, which functions as a type of electronic metal detector, over the surface of the land. More information may be found atDRAINFIELD PIPE LOCATION, PRECISE
For the purpose of locating the septic tank, ground scanning radar was used: Hidden septic tanks, underground oil tanks, and other items beneath the surface of the earth can be detected using radar. Many of the companies who provide underground oil tank finding services are also capable of delivering this (more expensive) service.

Warning about using metal detectors or electronic pipe sensors to find Septic Tanks

Metal detectors or probes that indicate the course of an underground pipe are great and quick methods of locating buried drain and septic system components, as well as other buried infrastructure. However, on an older property, we’ve had an odd problem that may have been quite disastrous. If your property is old, it may contain numerous generations of underground cables and pipes, which can cause errors in the readings from sensors such as those for buried pipe or buried septic tank monitoring.

After attaching a transmitting unit to a pipe at the gas meter, the technician proceeded to paint a yellow line over our (at the time frozen) earth with a paintbrush.

We started digging 18 inches deep using a jackhammer to break through frozen earth in order to locate a water pipe “a safe distance away from the yellow line indicating the gas line As one might expect, we came across the gas line itself while we were excavating!

Keep an eye out for: Excavation equipment such as backhoes, wrecking bars, and jackhammers should not be used in areas where potentially dangerous utilities are underground.

Why Use GPR for Septic Tank Locating?

The 19th of August, 2016 Finding tanks and drums with GPR is simple, quick, and accurate. If your septic tank becomes blocked, you’ll be left with nothing but a headache on your hands. Clearing the blockage might be a simple process, but locating the tank in the first place can be a time-consuming undertaking. If your tank is buried behind concrete, there is no manual method to locate it without the use of ground penetrating radar. The use of GPR is preferable even when septic tanks are buried in yards beneath layers of dirt since it is more accurate, faster, and dependable than other techniques of identifying septic tanks.

Accurate

Ground penetrating radar is a type of radar that sends radio waves into whatever it is scanning with the use of a transmitter, a receiver, and a central computer. The waves are then reflected back to the receiver by whatever lies beneath the surface of the water or ice. The computer is then able to decipher the signals and create a three-dimensional representation of what lies under the surface.

Fast

Because the whole system is contained inside a single component, the results of a GPR scan may be printed and analysed by a qualified expert as soon as the scan is complete.

Other Methods

The most traditional method of identifying your septic tank is to use a probe to dig about in the earth until you locate your tank. Locate the sewage line from the installation documentation from when the tank was installed, and then follow the directions on the line. From the map, you should be able to make an educated guess as to where the tank could be hiding. If you weren’t the original owner, or if you acquired the tank from a prior owner, and you don’t have the necessary documentation, this might be a difficult task.

How do you know when you’ve finally made it to the gas station?

How Do I Find My Underground Septic Tank?

Because your septic tank is subterranean, it might be difficult to locate it when you need it. What is the best way to locate your underground septic tank? The best strategy is to rely on ground-penetrating radar to locate and destroy targets. GPR services provided by GPR Arkansas allow you to “see” underground, allowing you to pinpoint the exact location of your septic tank. Septic tanks are critical components in the wastewater and sewage treatment process for residences and properties that are not linked to a municipal sewage system.

According to the EPA, “septic tank-soil absorption systems are the most widely-used type of on-site home waste disposal.

It is, nevertheless, always crucial to be aware of the exact location of your septic tank in your home.

In the same way, if you’ve newly acquired a home, knowing the location of the septic tank is just as vital as knowing the borders of your new property.

Furthermore, for property owners who intend to excavate, being able to pinpoint the exact location of their underground tank will help to guarantee that they do not accidently damage or breach the system.

How do you find where your underground septic system is located?

Some hints might steer you in the correct way if you pay attention to them. In your basement, you should look for your sewer pipe. It can point you in the direction of the best septic system for your needs. A conventional septic tank, on the other hand, can be positioned anywhere from 5 to 25 feet away from the house. That is a significant amount of ground to cover in order to locate a precise location. Traditionally used metal detectors may have difficulty locating a septic tank due to the fact that they are frequently constructed of concrete, fiberglass, or plastic.

Even if you believe you have located the tank, it is possible that you have just uncovered a rock or other subsurface impediment.

The best way to find a buried septic tank is to use GPR

Ground-penetrating radar (GPR) is a cutting-edge technology that allows you to “see” underground. It’s been utilized by homes, companies, and towns all around the country as a proven method of locating underground utilities, storage tanks, pipelines, masonry, and other concealed things, and it’s now available to everyone. GPR makes use of high-frequency polarized radio waves to accomplish its mission. GPR cart (which seems to be a high-tech push lawnmower) is moved over the area that has to be scanned.

It is possible for radio waves to be reflected, refracted, or dispersed back to the surface when they come into contact with an object or a boundary between materials.

In the end, you’ll get a map of what’s below the surface of the water.

Ground Penetrating Radar to Map Septic Leach Field Drainlines

You have arrived to the following page: Ground Penetrating Radar to Map Septic Leach Field Drainlines | Case Studies | Home Pyramid Geophysical Services has used ground penetrating radar (GPR) to find and outline the extents of septic leach fields and septic drain lines at a number of different locations around the country. Typically, these drain field systems are formed by excavating trenches in the earth, into which perforated drain lines are installed, and then covering/encircling the entire system with gravel.

As a result, GPR anomalies that are obvious, discrete, and easily distinguishable are frequently observed between the native soil and the gravel/drain lines, which is typical of the situation.

When Pyramid used a GSSI UtilityScan DFradar equipment to map out the drainage pipe, it was discovered that it was around 2 feet below the ground surface.

However, due to the heavily compacted nature of the ground surface across the majority of the site, it was not possible to carry out any additional hand probes, leaving a high degree of uncertainty as to the locations and extents of the drainage lines.

All of the survey questions were answered in less than 2 hours. Click here to see a complete video outlining the steps involved in mapping septic drain fields using ground-penetrating radar (GPR).

Additionally, Three Oaks may plan and secure the necessary permits from the local health authority for septic system relocations for afflicted systems. The use of Ground Penetrating Radar (GPR) to locate septic systems and drainage pipes is performed by a licensed soil scientist.

Additional Soils, Septic Systems, and Perc Testing Services

When it comes to septic systems, the most commonly used components are the tank and the field (also known as a leach field), or a cesspool, which is now considered outdated. It is a mechanism for disposing of human waste, notably that generated in the restroom or the bathroom. In general, the septic tank’s primary duty was to deposit solid waste, while the leach field’s primary role was to distribute waste water that passed through the septic tank. Concrete cuboids are the most often encountered septic tanks, as opposed to underground storage tanks (USTs), which are primarily steel cylindrical structures.

However, after being abandoned for a long period of time, it is occasionally covered with dirt or pavement.
The metal detector is the first instrument you should attempt if you want to locate a septic tank, in the hopes that there are steel manhole covers or that the tank is composed of reinforced concrete containing rebar.
Ground penetrating radar (GPR) is likely to be the most effective backup option if the first method fails.

The first approach for locating the septic/leach field would be to map the conductivity of the groundwater.
In certain cases, the change is really minor, yet it is still noticeable.

GPR may be used alone to detect a leach field in some cases, but it is more time consuming and difficult, and the results are not reliable if the soils in the searching region have been severely disturbed, as has been the case in some cases.

Find Buried Tanks with Ground Penetrating Radar (GPR)

When it comes to locating hidden things such as petroleum tanks, water pipes, sewer lines, and other subterranean objects, executing a Ground Penetrating Radar (GPR) survey is the most effective way available today. GPR surveys (also known as tank sweeps) are non-destructive evaluations of subsurface items. A hidden subterranean storage tank is represented by the white rectangle in the photograph (UST). Prior to the GPR scan, there were no evidence that the tank had been present. During a real estate deal, it was discovered that the property had previously been heated by oil.

GPR Applications and Their Uses

Locate buried tanks
Locate secret household oil tanks

Locate buried underground tanks Identify the location of previous tank excavations. finding the location of water and sewage pipes
Identify and locate metallic and nonmetallic pipelines, as well as utility cable. Pitstrenches holding metallic and nonmetallic material should be delineated. Distinguish between regions that have been previously excavated and backfilled Determine the presence of underlying barriers, such as rocks and ancient foundations.

GPR Overview

Q.What is GPR (Ground Penetrating Radar) and how does it work? As previously said, GPR is radar, and the system is installed on a cart (see photo below) that also holds the carry and GPR antenna. From the transmitting antenna, the antenna emits brief pulses of high-frequency EM energy into the ground, which is known as ground radiation. An electromagnetic wave is created when an EM energy (wave) encounters the interface of two materials with differing dielectric properties (for example, the interface between a tank and the ground).

Because GPR signals cannot pass through solid metal objects such as tanks or metal pipes, the GPR signal bounces off the item (reflects the EM signal) and returns to the surface, where it is read and logged, as explained earlier in this article.
The difference between these two readings is what allows a GPR specialist to distinguish between a buried object and typical soils in order to locate the buried object.
An picture such as the hump, mountain, or convex shape shown on the screen below is what alerts the GPR specialist that a tank is there.

A.Metal detectors and ground penetrating radar (GPR) are apples and diamonds, respectively.
When metal is detected, metal detectors generate beeping noises, and when GPR is used, a picture is sent.
All oil tanks will be discovered in the vicinity of a structure (a home), which will be distinguished by a metal signature.

Wire mesh or metal rebar can be embedded into concrete sidewalks and driveways to provide reinforcement.

Metal detectors will pick up on all of these sources of metal and provide false positive results.

A.The GPR system is installed on a wheeled carrier vehicle (about the size of a lawn mower) that is manually propelled by the GPR operator.

As the radar unit travels along the ground, the ground scans are gathered and evaluated by the radar unit’s controller.

What is the difference between a GPR and an X-ray?

No, x-rays and GPR scanning are two distinct types of scanning.

Q.How far can ground penetrating radar (GPR) penetrate or see below the earth?

In addition, higher frequency signals attenuate at a greater rate than lower frequency signals.

In order to locate a subsurface tank or a utility that is enclosed within a concrete floor, there are particular radar antennas that can be employed in certain situations.

Q.Does radar (GPR) have the ability to penetrate concrete and asphalt?

Due of the several benefits that GPR has over metal detectors, it is frequently utilized on commercial properties.

As a result of running the GPR unit over an area that contains subsurface information, the GPR technician captures the information, which includes the position and depth of the buried information.

The GPR survey can then proceed when the region has been indicated with a marker.

A Curren is a licensed tank removal and testing firm, which is correct.

Are you looking for information about Removal?

Yes, you should be concerned since it is possible that the tank has spilled, and this is a matter that has to be answered firmly.

The remediation of leaking tanks might cost thousands of dollars.

Those who live in houses with oil tanks How do you ensure the tank that was removed did not leak?

The tank closure or tank removal report would be a multi-page document confirming that the tank had been removed and that testing (laboratory analysis) had been completed, as well as a written declaration from the tank removal/testing business saying that the tank did not leak throughout the process.

You do not have the information you require to be positive that the tank has not leaked.

There is no need to be concerned if you have a record detailing the tank removal, as well as soil testing indicating that the tank did not leak.
Is that a sufficient permit?
The label above, which indicates that the tank has been removed and has been APPROVED, comes from the local building department.

Unlike environmental agencies such as the NJDEP in New Jersey or the PADEP in Pennsylvania, construction authorities are not regulated by the government.
If you are purchasing a home that was built between 1900 and 1990, there is a good chance that oil heat was utilized in the construction of the structure.
What if I told you that the number of tank sweeps has grown dramatically in the last ten years?
Consider the fact that, while you may not be concerned about an oil tank, the person to whom you sell the property may be, and if they discover a tank, you will be held liable for the tank’s maintenance.

Ground penetrating radar (GPR) is a non-destructive scanning technology for subsurface imaging that may be used in a variety of applications. It operates by giving out electromagnetic (EM) waves and then monitoring the EM waves that are reflected back to the source. Underground targets, such as buried pipes, are located by sending electromagnetic waves into the earth, where they are reflected back by the targets and revealed as their presence and position are revealed. As a rule, the horizontal location of subterranean targets can be quite accurate, but the depths of these targets can only be approximately determined.

As a result, GPR can identify both metallic and non-metallic objects in remarkable detail as a result of this improvement in sensitivity.
In both interior and outdoor contexts, GPR scanning may be used to gather information.
The use of GPR scanning at a project site causes minimum disruption to routine business activities on the job site.
The performance of GPR scanning is often greater when used to materials that are less electrically conductive.
Furthermore, because concrete slabs lose moisture over time and become less conductive, GPR often operates better over old rather than fresh concrete slabs, as an example.

Utilities infrastructure installation and maintenance specialists are familiar with the difficulties of traversing decades of unregulated and unmapped underground wiring. The locator requires a data collecting platform that can perform the following functions among a diverse set of tools:

The ability to operate in a variety of terrains and soil conditions. Visual data may be recorded using 3D imaging and mapping capabilities. Converting discoveries into actionable information is essential.

Ground-penetrating radar systems from US Radar are capable of meeting all three of these requirements and more. Self-calibrating antennas allow the systems to adapt to local soil conditions, and the devices’ sturdy hardware can survive physical damage over an extended period of time. Our software suite also enables the operator to convert discoveries into 3D photos and detailed maps, which may then be further processed using advanced post-processing techniques. The information about utility location captured by your GPR system might be further analyzed by the operator once it has been recorded.

This establishes a consistent point of reference for all contractors, allowing them to operate in unison to produce a safer and more efficient workplace.

Utility Locating Applications

Because ground penetrating radar (GPR) gives a comprehensive picture of the subsurface, it is an essential component of any infrastructure construction or maintenance operation that requires damage avoidance assurance. Discover items that one-call locators may or may not be able to locate, such as private utility lines, underground objects of various types, and more. Here are some examples of utilities that GPR can assist in identifying:

Missing valves
Water boxes
Abandoned lines
An illegal or unknown connection
Plastic or PVC
Clay pipes
Concrete pipes
Transite pipes
Metal pipes Conduit, water, wastewater, gas, electricity, CATV, telecommunications cable, fiber optic, septic tanks, voids, manholes, and more are all covered.

SEPTIC DECOMMISSIONING

In accordance with OAR 340-071-0185, septic tanks, cesspools, and seepage pits are required to be decommissioned when the systems are no longer needed to be in operation. In order to document the decommissioning and to record the location of the decommissioned septic system, a Decommissioning Permit is necessary. If the following conditions are met:A sewerage system becomes available and the facility it serves has been connected to that sewerage system;The source of the sewage is permanently eliminated (e.g.

a home, addition, garage, ADU, deck, etc.) is proposed within 10 feet of an abandoned system;A land division on a property with an abandoned system;A property line adjustment that will result in the closure of an abandoned system;A land division on Please keep in mind that septic decommissioning is NOT REQUIRED for a real estate closing.

What is an abandoned septic system?

An abandoned septic system is often comprised of a cesspool OR a septic tank connected to either a drainfield or a seepage pit, depending on the situation.

CESSPOOLS

Typically, cesspools are cylinders 3 to 4 feet in diameter and 15 feet deep, with perforations constructed of either brick or pre-cast concrete rings. Cesspools are used for a variety of purposes. Cesspools are often found east of the Willamette River, particularly in rural areas. Cemeteries were frequently built of brick until the 1950s, and they still are today. Cesspools were generally constructed of precast concrete rings beginning in the 1950s.

SEPTIC TANKS

Septic tanks are rectangular in design, and are typically 5 to 7 feet long by 5 to 7 feet deep, depending on the manufacturer. Concrete or metal septic tanks were used for septic systems.

Septic tanks are often found west of the Willamette River, especially in rural areas. Septic tanks discharge onto a drainfield or a seepage pit, depending on their design. (Decommissioning of the drainfields is not required; just the tank and/or seepage pit are required to be decommissioned.)

SEEPAGE PIT

Seepage pits are a type of cesspool that is preceded by a septic tank.

How do I determine whether a property has a septic system?

1. Septic systems were used in homes and buildings that were designed with plumbing and erected prior to the availability of a public sewage system. 2. Go to and type in the address of the property in the search box. PermitsZoning may be accessed by selecting the button and then selecting the Permits button. Take note of the year that was constructed on the Summary page.3. Click on Historic Plumbing at the bottom of the page, then on each ID link to access the plumbing records that are currently available through the Historic Permit Records Viewer.

A permission record may consist of numerous pages, depending on the circumstances. On the front of most plumbing documents is a table with a narrative description, and on the reverse is a representation of the system. For the sake of keeping the front and back pages together, it is advised that you print double-sided or two records per page. Plumbing record tables, narrative descriptions, and drawings may all contain references to septic systems. Most of the time, there will be no evidence of a septic system (see page 2 for information on how to identify one on site).

When there is no clear indication of DECOMMISSION FILLED in the data, the septic system has not been decommissioned.

Where is an abandoned septic system usually located?

The primary plumbing vent stack (typically 4″) coming through the roof should be identified; then picture a straight line running from the stack to the external foundation; finally, find and follow the original plumbing line to either the cesspool or the septic tank as follows: Sewage ponds are often located 10-12 feet directly out from the foundation, in line with the main plumbing vent stack on the roof.

Approximately 3 to 5 feet below ground surface (bgs) to the top of the building if the structure does not have plumbing in the basement, or approximately 8 to 10 feet below ground surface (bgs) if the building has.

Septic tanks are found in a variety of locations (may be 5 to 30 feet from the foundation).

**Please keep in mind that the most reliable method of locating the original sanitary sewer line is by digging for it and following it**

Replacement Cesspools

They are typically positioned roughly 10 feet away from the original cesspool, either straight out or offset at a 45° angle from the original cesspool (see diagram). A cesspool that is 22 feet away from a structure, for example, is very certainly a replacement cesspool, regardless of what the plumbing record narrative may or may not indicate. The same goes for situations in which a new cesspool was installed in 1971, but the house was built in 1943; two cesspools will need to be found, one made of brick and one made of concrete.

How do I decommission a septic system?

Complete and send a Sanitation Evaluation Application, along with the applicable payments, to the following address:

In person: Visit the Development Services Center, Trade Permits, 1900 SW 4th Ave., first floor, Portland, OR 97201, which is located at 1900 SW 4th Ave., first floor. Call 503-823-7310 and choose option 1 for hours of operation. For trade permits via mail, send a completed application together with a cheque made payable to the City of Portland to the attention of Trade Permits at 1900 SW 4th Ave. Suite 5000, Portland, OR 97201.

Step 2:

Determine the location of the tank and/or cesspool/seepage pit. A. Pump out any sewage that has accumulated in the system (if applicable)*. Any leftover solid and liquid wastes must be pumped out by a sewage disposal service who is licensed by the DEQ. Before the inspection may be approved, a copy of the pump receipt must be provided. For septic tanks that are water-tight, drill holes in the bottom to allow any ground water to drain through. B. Fill up the gaps with appropriate material (you cannot use ordinary soil or dirt).

Materials that are appropriate for this project include: minus gravel (34 inch), masonry, or playground sand. Concrete slurry (concrete slurry)
If you’re using sand or gravel, fill in lifts that are 1 to 5 feet thick and wet down and/or tamp to ensure sufficient compaction before laying the foundation. Depending on whether a new foundation will be built within 10 feet of an existing septic system, the fill may need to be put as structural fill and compaction testing may be necessary. It is possible that you may need to consult with your engineer.

C. Leave the top 12-18″ of the cesspool empty and the original pipe leading to it exposed so that the inspector may see what type of material was used to construct the system, if possible.

Step 3:

Request the inspection following the completion of the filling process and before covering the system (Step 2C) Please keep in mind that an examination is necessary even if the system cannot be discovered. We must describe whether or not appropriate attempts were made, and whether or not further digging is necessary. All excavations should remain open.

A. Call the number 503-823-7000. (IVR Request Line) B. Request842 for a decommissioning examination

Maine Septic Services

The following are some of the most frequently asked questions about septic tanks.

If you don’t find your question answered on this page, please contact us and we’ll be happy to assist you further.

Q. How often should I have my septic tank serviced?

It is recommended that you replace your A/C system once every two to five years, depending on how often you use it and how many people are utilizing the system.

Q. Do you have to drive on my lawn to service my septic tank?

A. No, it is not our policy. We carry roughly two hundred feet of hose, which is generally more than enough for most residential applications. We may bring additional hose if necessary if we are given advance notice.

Q. Is it O.K. to use drain cleaners with a septic system?

A. Avoid using drain cleaners and other chemicals whenever possible. They have the potential to disrupt the naturally existing biological processes in the septic tank and leaching region of the property. One gallon of some hazardous compounds can damage twenty-two million gallons of ground water, according to the Environmental Protection Agency.

Q. Do I need to use additives in my septic system?

In order to maintain a healthy pH balance in your system and to encourage better sewage digestion, we recommend that you flush one cup of baking soda down the toilet once a week.

Q. What do you do with my septage once it is removed from my tank?

It is transported to a Maine DEP-licensed disposal facility, such as a Wastewater Treatment Facility, where it is disposed.

Q. How do I find my septic tank?

A. Here are a couple of approaches you may try.Septic tanks are normally rectangular in form, measuring around 4 x 8 feet.

You’ve probably come across a rectangular stretch of ground where the snow melts first in the winter and the grass burns first in the summer. An underground septic tank can be submerged to any depth between flush with the surface of the earth and more than 6 feet. When you look down in your basement, you can see where the sewer pipe exits through a hole in the wall. Take note of how far the pipe extends below the top of the foundation and whether or not it exits through the wall directly. When looking from the outside of the house, this will provide you with an approximate orientation for the pipe leading to the tank. To determine how far the tank is below grade, measure down from the top of the foundation wall to the ground’s surface and subtract that measurement from the inside measurement (also subtract another 6 because the top of the sewer pipe is usually 6 down on either side or end of the tank) to get a rough estimate of how far the tank is below grade. You can probe for the tank top using a steel bar or rod that you push into the earth. Keep in mind that you are searching for a flat rectangular space around 4 x 8 inches below the surface of the earth
Many septic systems are not gravity systems and require pumping to function properly. Excavation around your septic tank and/or pump tank should always be done with extreme caution since electrical lines can be hidden underground and are not usually marked, posing a possible electrical danger. Never fear if you can’t identify your septic tank
We have specialized equipment that can help us locate the tank if necessary
Just give us a call.

Q. Can my septic tank baffles be repaired?

A. Yes, we replace a large number of deteriorated concrete baffles with PVC baffles each year.

Q. Are septic tank filters any good, don�t they plug up frequently?

An absolutely necessary addition to your septic tank is the installation of a Zabel filter by our team. These filters help to keep particles down to one-sixteenth of an inch in the septic tank by trapping about 80% more solids. Over the years, we’ve discovered that the Zabel filters appear to be the most effective. It is just necessary to remove the clogged filter, wash it well and replace it when the problem arises. In most cases, filter maintenance is performed at the same time as septic tank maintenance.

Q. I hate digging up my septic tank and having the mess in my lawn every three years or so.What can we do to save all that mess?

The installation of a riser above the service cover is recommended. It is recommended that each of the access covers for the filter and pump be equipped with a riser as well. Risers are now required under the State of Maine’s Subsurface Rules. We choose to use Fralo risers because they may be erected in sloping grass areas and because they are simple to install flush with the ground surface.

Q. Do you have any other tips you can give me?

A. Without a doubt! View the State of Maine’s Ten Tips for Maintaining Your Septic System for more information.
