- Septic Tank Lateral Line Installation Step 1. Install each lateral line into the inlet holes in the junction box. The end of the pipes must be flush with the Step 2. Inspect the height of the pipes by measuring the distance from the bottom of the box to the bottom of each inlet Step 3. Place
How deep should septic laterals be?
A typical drainfield trench is 18 to 30 inches in depth, with a maximum soil cover over the disposal field of 36 inches.
Can I install my own leach field?
You may also need to pull a permit to put in a new leach field. A leach field is an important part of a septic system. It disperses fluid from the septic system over a large area of soil adjacent to the building it services. Building your own leach field is physically difficult, but it can save you lots of money.
What do you use for lateral lines?
The most common replacement pipe is polyvinyl chloride (PVC plastic). Historically, the water service line was typically buried with the sewer lateral in the same trench.
What are lateral lines septic system?
Septic tank lateral lines are also known as percolation pipes. These are the perforated pipes that extend from the outlet of the septic tank below ground into the soil. The purpose of these lateral lines is to provide a network of pipes that the effluent from the septic tank runs through.
Can you drive over lateral lines?
In sum, driving over the leach field in any vehicle larger than a child’s bicycle is a bad idea. Heavy vehicles may actually crush buried leach field lines, or they may compress the soils around the leach field, either of which leads to failure. Driving on or parking on leach fields will destroy them.
How much fall should a leach line have?
In a conventional gravity system, the pipe from the house to the septic tank, and the outlet pipe from the tank to the distribution box or leach field, should both slope downward with a minimum slope of 1/4 in. per ft. (1/8 in. per ft.
What is the slope for septic lines?
A typical septic tank has a 4-inch inlet located at the top. The pipe that connects to it must maintain a 1/4-inch-per-foot slope toward it from the house. This means that for every 10 feet of distance between the tank and the house, the inlet must be 2 1/2 inches below the point at which the pipe exits the house.
Can you have a septic tank without a leach field?
The waste from most septic tanks flows to a soakaway system or a drainage field. If your septic tank doesn’t have a drainage field or soakaway system, the waste water will instead flow through a sealed pipe and empty straight into a ditch or a local water course.
How do I calculate the size of my septic drain field?
- The size of the drainfield is based on the number of bedrooms and soil characteristics, and is given as square feet.
- For example, the minimum required for a three bedroom house with a mid range percolation rate of 25 minutes per inch is 750 square feet.
Can a leach field be on a slope?
1. The maximum slope allowed for leach line trenches is 40% (2-1/2:1 slope). 2. All leach lines on steep slopes shall be installed in five-foot deep trenches with 12 inches of leach rock below the leach pipe or with approved chambers or other gravel-less system.
How deep should a leach field be?
Septic drainfield trench depth specification: A typical septic drainfield trench is 18 to 30 inches in depth, with a maximum soil cover over the disposal field of 36″; or per the USDA, 2 feet to 5 feet in depth.
What type of pipe is used for leach field?
Leach pipes are usually made of perforated PVC pipe. To encourage the final product to trickle into the soil, the pipes are bedded in gravel and sand or sometimes are covered with plastic septic chambers.
Do drain field worms work?
Their burrowing near the surface actually helped the septic wastewater spread through the soil more evenly, resulting in better cleansing of the water. Had they been nightcrawlers, the worm burrows might have drained the trenches so fast that it would bypass the soil filtering.
Septic Tank Lateral Line Installation
A sewage disposal vehicle will be dispatched by our pumping crew. It is our responsibility to connect that truck to your septic tank, switch on the pumps, and remove the trash and sludge that has accumulated there. A couple of hours is generally plenty, while the precise time required will depend on how much sewage you have and whether or not we meet any difficulties along the route. The majority of the time, though, we are in and out in no time! Make contact with WasteWater Logistics right once to book a septic pumping service.
It won’t take long before your septic tank is back in tip-top form!
- 4-inch PVC perforated pipe
- A shovel
- A backhoe
- A bubble level
- Rosin paper
- And a tape measure
Dump the dirt onto the rosin paper slowly so that the rosin paper does not shift while you’re doing it.
Townships are in charge of enforcing their own building regulations. Check with your local building inspector to see whether or not a permit is required.
- Each lateral line should be inserted into one of the intake holes in the junction box. A quarter inch overhang into the junction box is required at each end of the pipes
- Otherwise, they must be flush with the side of the junction box
- The height of the pipes should be checked by measuring the distance from the bottom of the box to each input pipe’s bottom. Placing cement around the exterior of each pipe will help to keep the pipes connected to the junction box. Build a wall of stones around all four sides of the junction box until there are 10 to 12 inches of stone beneath the pipes. Gradually lower the stones until the slope is sloping down one-quarter inch per foot
- Install perforated pipes from the junction box to the absorption field, extending them in a parallel fashion across the absorption field. A quarter inch per foot of pipe spacing is required, with the pipes sloping down away from the junction box at a rate of one-quarter inch per foot of pipe spacing. Your township may be able to provide you with particular lengths based on your local construction rules. Fill the area surrounding the pipe and on top of it with stones to ensure that the pipe does not move. The pipe should be covered at least two inches above the top of the pipe. Placing red rosin paper on top of the stones will prevent dirt from being incorporated into the stones. Fill in the remaining earth into the drain field on top of the rosin paper to complete the drainage system.
The Drip Cap
- It is critical to the overall operation of a septic system that the lateral lines be properly installed. Shovel stones around outside of the junction box until there is 10 to 12 inches of stone beneath the pipes. A quarter inch per foot of pipe spacing is required, with the pipes sloping down away from the junction box.
How to Install a Septic System
Documentation Download Documentation Download Documentation In rural regions of the nation where waste water treatment is not accessible, private on-site wastewater treatment systems (POWTS), also known as septic systems, are utilized largely to treat waste water. Gravity fed/conventional systems are divided into two broad categories: 1. gravity fed/conventional systems and 2. alternative (pump) systems, which include aerobic treatment units (ATUs.) In most cases, electric pumps are used in alternative systems.
However, in many health jurisdictions across the United States, it is still feasible for an individual property owner with heavy equipment operation skills to utilize a backhoe to establish a septic system on their land.
- 1 Make a plan and design for your system. Performing a site survey and conducting a percolation (soil) test on the area where the POWTS is to be placed are both required initial steps in any septic system installation. In order to create a system, it is necessary to first gather information from surveyors and conduct a soil test. It is then possible to submit an application for the necessary permissions and approvals.
- 1 Organize and plan your system’s components. Performing a site assessment and conducting a percolation (soil) test on the area where the POWTS system is to be placed are two of the initial steps in any septic installation. In order to develop a system, it is necessary to first gather information through surveys and soil tests. Permits and permissions can then be sought for the project, if necessary.
- 1 Plan and develop your system from the ground up. Before beginning any septic system installation project, a site study and percolation (soil) test on the area where the POWTS will be installed should be completed. According to the findings of the survey and the results of the soil test, a system can then be designed. Following that, the necessary permissions and approvals may be sought
- The following are examples of soil test findings that have an impact on the design:
- The soil type and layering (sand, clay, rock, and where it is placed in relation to depth)
- The soil’s ability to drain and filter wastewater
- And the soil’s ability to drain and filter wastewater
- 2Wait for clearance before proceeding. The system may be deployed once all of the relevant permissions and approvals have been obtained. Make certain that all of the steps listed below are carried out in accordance with all applicable laws, plumbing rules, and building codes. Advertisement
Await confirmation of your request 2. The system may be deployed as soon as the required permissions and approvals are obtained. Make certain that you follow all applicable laws and plumbing and building rules while doing the tasks listed below. Advertisement;
- 1 Assemble the equipment and tools that will be used throughout the dig. You will require the following items:
- Backhoe, laser transit, and grade pole are all included. A 4″ Sch. 40 PVC pipe (and fittings, if necessary)
- A 4″ ASTM D2729 perforated pipe
- A 4″ASTM D3034 pipe and fittings
- A 4″ Sch. 40 vent cap and test cap
- PVC primer and adhesive
- A 4″ Sch. 40 vent cap and test cap The following tools will be required: Saw (either hand saw or cordless reciprocating saw)
- Hammer drill and bits (for drilling through walls if necessary)
- The following items are required: hydraulic cement (to seal surrounding pipe if pipe is going through wall)
- Stone measuring an inch and a half and cleaned (amount varies depending on system size)
- Tape measurements (both ordinary and at least a 100-foot-long tape)
- Septic fabric (cut to 3′ length or less from a roll)
- Septic tank and risers (concrete or plastic if allowed)
- Riser sealant such as Con-Seal (for concrete) or silicone caulk (for plastic)
- A septic filter (such as a Zoeller 170 or similar) if one is necessary
- A distribution box (either concrete or plastic, if more than two laterals are being run)
- And a septic tank.
- 2 Determine the location of the entrance to the building in relation to the location of the septic tank. Make an excavation at least 2 feet deep and drill a hole through the wall, or go deeper and drill a hole beneath the footing, depending on your preference or the need. Because this is precisely what a gravity-fed system is designed to accomplish, expect the flow to continue to flow downhill from here. When transferring waste from the tank to the drain field, it does not employ any mechanical methods other than gravity.
- The pipe should be 4″ Sch. 40 and should extend at least five feet outside the structure toward the tank, either through the wall or beneath it. Set it level where it will pass through a wall or under a footing, and from there, run it with approximately 1/8″ of pitch (slope) every foot of length toward the septic tank until it reaches the tank. If necessary, go even farther into the tank or all the way into the tank. If this is the case, switch to 4″ 3034 with the appropriate adaptor and pipe 3034 toward the tank.
- Make sure you use a test cap on the end that will be entering the building. It is recommended that if you are going through a wall, you seal the area around the hole with hydraulic cement both inside and outside
- Do not run too much pitch out to the tank. If there is an excessive amount, the water will run away quicker than the sediments, resulting in the solids remaining in the pipe. Additionally, depending on the depth of your drain field and how close it will be to the tank’s outflow, there may not be enough pitch to get to the drain field.
- 3 Dig a hole large enough to accommodate the installation of the concrete aerobic tank below ground. Make use of the laser transit to “shoot” the top of the pipe that leads out to the tank with the laser. The distance between the top of the intake and the bottom of the tank is measured in feet and inches. To the number you fired off the top of the pipe, add this (go up on the grade pole) + 1 1/2″ to get the total. The depth of the grade pole has now been adjusted to the desired depth. Using this, continue to drill the hole to the desired depth
- Prepare your leech field by laying it out and excavating it according to the results of the test performed during the permit application procedure. Maintaining a good flow between the tank and the drain field should be considered when planning out and digging the tank.
- Using the results of the leech field test conducted as part of the permit application procedure, lay out and dig your leech field. Maintaining a good flow between the tank and the drain field should be considered when planning out and digging.
- A pump chamber after the septic tank should be installed The pump chamber, also known as a pressure tank or dosing tank, is where the electric pump is housed, which is responsible for transporting wastewater from one location to another and finally into the drain field for final disposal.
- Set up the pump chamber in the same manner as you would a septic tank. The effluent pump and floats are housed in the pump chamber, and they are responsible for pumping the effluent out to the drain field at predetermined or scheduled intervals. This is a hermetically sealed system. To ensure that the electrical installation complies with state standards, it is frequently necessary to hire a qualified electrician. It is important to remember that in places with high groundwater, the pump chamber or additional ATUs may remain essentially empty for long periods of time, and that these tanks may need to be safeguarded from floating by the installation of additional weight or other protective features.
- Secondly, all construction details, including the layout of all sewers outside of the home, the location and depth of all tanks, the routing and depth of pressurized effluent lines, and other system components, such as the drain field and any additional ATUs, must be consistent with the septic system plans approved by the local county health department. Cover the tank and pressurized lines once the inspector has given his final clearance and the system has been turned on. Advertisement

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

- Keep the perforated pipe for the leech field in a vertical position while installing it to avoid having the holes in the pipe turn downward. It is necessary to lay the perforated drain field pipe ASTM 2729 dead level, so that the printed line on the pipe is facing up. The perforations on both sides of the pipe are on both sides of the pipe. All of the sections of perforated pipe are cemented together, and the ends of each leach line are capped to complete the installation. So, when waste water enters the pipe, it will fill the pipe to the height of the perforations and overflow from ALL of the holes, utilising the whole leach field as a means of treatment. In certain health authorities, you can utilize waste water to water grass or decorative plants, trees, vegetable gardens, and fruit trees if you place the perforated pipe on a slope. However, the water must first be cleaned by the system (tertiary treatment includes disinfection) in order to prevent pathogens (germs) from the septic system from being discharged into the environment throughout the process. Make sure to check with your local health authority to verify if the practice known as “reuse” is permitted in your community.
Things You’ll Need
- The following tools are required: backhoe tractor, trencher, shovel, contractor’s laser level and rod, or a surveyor’s transit. Septic tanks
- PVC pipe with perforations
- Material for embedding
- PVC adhesive, PVC fittings, and a septic tank outlet filter are all included. Hand saw
- Course file

An underground trench below the level of the septic tank contains a perforated sewage pipe, which is often composed of PVC in modern systems. The sewer pipe is embedded in gravel in the trench. The pretreatment portion of your septic system is where microorganisms digest the sewage particles, which is where your septic tank is located. The tank allows partially processed liquids to travel down a closed conduit to the septic field, also known as the leach field, where they are disposed. Despite the fact that the septic field is at a lower elevation than the tank, the field and the pipe that runs through it must be perfectly level.
Before you can build a septic system, you must get approval from the permitting authorities in your county or city. The plan for the project will indicate the elevation and layout of the trenches for the perforated pipe, as well as the location of the perforated pipe.
- An underground trench below the level of the septic tank contains a perforated sewage pipe, which is commonly constructed of PVC in modern systems. The sewer pipe is embedded in gravel in the trench. The pretreatment portion of your septic system is when microorganisms decompose the sewage particles, which is where your septic tank comes in handy! The tank allows partially processed liquids to flow through a closed conduit to the septic field, also known as the leach field, and into the sewer system. The septic field is at a lower elevation than the tank, but it must be level in order for it and the pipe that runs through it to function properly. Before you can build a septic system, you must first obtain approval from the appropriate permitting authorities in your county or city. The project design will illustrate the elevation and layout of the trenches for the perforated pipe, as well as the location of the perforated pipe.
Things You Will Need
- Geo-textile fabric
- Builder’s level (sometimes called a transit level) or a laser level
- PVC self-priming adhesive
- Avoid deviating from the plan that has been accepted by your permitting authority. If you do not adhere to the plan during the installation process, the county or city will not accept the finished product and may even order you to knock it down and start again. Planting trees or other plants with invasive roots on or near your drain field is not recommended. A tree’s roots can grow through perforated piping and follow it all the way up to your septic tank, causing the entire system to fail.
How to Install a Septic Tank and Field Line Sewer System
The installation of a septic tank is not a do-it-yourself activity. Image courtesy of Kwangmoozaa/iStock/Getty Images. You shouldn’t try to build a septic system yourself unless you are a heavy equipment operator or a professional. Even if you have heavy gear at your disposal and are familiar with how to use it, you will still require a significant amount of expert assistance. There are many professionals you’ll need: a soil expert to assess the site, an engineer to design an acceptable system, a plumbing contractor to construct and connect pipes, and maybe an electrician to assist with the installation of any pumps or timers that may be necessary.
Septic System Design Variations
A total of nine different types of septic systems are listed by the United States Environmental Protection Agency, and that doesn’t even include systems that are not gravity-fed and instead rely on a transfer pump. Septic tanks and a drain field sunk into the earth are the components of the traditional septic system. This is the system that most people envision, but it is only one of several options, and it is not necessarily the best one. It is possible that local health authorities will require an additional system, depending on the soil quality, topography, drainage conditions, anticipated usage, and other factors; in this case, it is necessary to hire an engineer who will work with the health authorities to design and obtain the necessary permits.
Installation Isn’t a Straight Shot
The designs are in hand, but it is not always a straight line from there to the actual installation for the homeowner who is working with an engineering firm. In actuality, Mr. To homeowners who are considering installing their own septic components, Rooter advises them to refrain from doing so. It is simply too risky to install a conventional system if it will result in poor drainage, ineffective plumbing in the house, or contamination of the local water table. However, if you are of the hardy do it yourself persuasion or if circumstances dictate that you do the job yourself, and you have access to an excavator and crane, the installation of a conventional system is relatively simple to understand and execute.
Installing a Conventional Septic System
A traditional septic installation begins with the excavation of a hole for the tank in accordance with the placement specifications provided on your approved plan. After putting the tank into the hole, you link it to the building sewer using 3- or 4-inch waste pipe, which must maintain a minimum slope toward the tank, and you run a drain pipe from the other end of the tank to a distribution box positioned in the drain field, as shown in the diagram. After that, you’ll need to dig a series of parallel trenches that will reach from this box all the way across the drain field.
Connect the pipes to the distribution box and cover the pipes with a sheet of plywood.
In order for a gravity-fed septic system to function properly, the building and drain field must be on a consistent downhill slope.
An alarm system that warns you if a fault occurs must be linked to the pump in addition to the power source.
Because maintaining the pump is a nasty endeavor, you’ll want to keep malfunctions to a minimum. For this reason, having the pump installed by a professional electrician who can guarantee the job is highly advised.
What Are Septic Tank Lateral Lines and Percolation Areas
Septic tank lateral lines are also referred to as percolation pipelines in some circles. Perforated pipes that extend below ground from the septic tank’s outflow and into the soil are referred to as leach lines. The goal of these lateral lines is to create a network of pipes via which the effluent from the septic tank may be sent and collected. After passing through these pipes, the effluent seeps out of the perforations in the pipes and infiltrates into the soil. The effluent eventually infiltrates into the ground through the lateral lines or percolation pipes of the septic tank.
An Essential Part of a Standard Septic System
The lateral lines of a septic system are critical components of the system. They can be found in both home and commercial septic systems, depending on the application. The proper operation of lateral lines is critical to the proper operation of any septic system. Septic tank effluent has nowhere to go when they are obstructed or not functioning correctly, resulting in a backup of sewage and the failure of the system.
UK 2020 Septic Tank Guidelines
Beginning in 2020, every basic septic tank system in the United Kingdom will be required to have septic tank lateral lines or a percolation area constructed. Stream and watercourse discharges will not be authorized directly into the environment. In order to comply with the regulations between now and 2020, everyone who has a septic tank that discharges directly into a stream or watercourse is required to create a soakaway or percolation area. A percolation area or soakaway following a septic tank installation in an existing landscape is not usually straightforward.
Installing a household sewage treatment system might be a viable alternative approach.
Compared to the installation of a huge percolation area, it is significantly more cost-effective to replace a septic tank with a sewage treatment plant instead.
When purchasing a sewage treatment plant, it is important to search for exceptional value in conjunction with a system that is certified to EN12566-3 specifications.
How to Install Lateral Lines Correctly
It is recommended that you get professional assistance when constructing your percolation area or lateral line configuration. The effluent ponding on the ground surface might be caused by a poorly built percolation region that is not functioning properly. Consequently, before you begin any work, consult with a professional, arrange for a site study, and then make certain that the septic tank installation you hire is skilled and adequately insured. The number of lateral lines placed is a function of the amount of space available.
- The number of people living in the house or structure
- The kind of soil in the region
- And the quantity of groundwater are all factors to consider.
How to Install a System Without Septic Tank Lateral Lines
Due to the fact that septic tank effluent is not treated to a high level of quality, lateral lines for septic tanks are typically necessary. A standard septic tank has a treatment level of roughly 30%, which is not very effective. A contemporary sewage treatment plant or aerobic sewage system, according to the contract, has a treatment efficiency of 95 percent or more. Systems such as the Biocell QuickOne achieve an even higher treatment level of 98 percent, resulting in effluent that is clean and transparent.
In other words, while an advanced sewage treatment system is more expensive than a standard septic tank, you save a significant amount of money by not having to add lateral connections.
Even if you do not have access to a stream or watercourse and you need to establish some lateral lines, you may install a lower number of lines after a sewage treatment plant since the effluent is much cleaner and it infiltrates into the ground much more easily after a sewage treatment facility.
Guide to Installing Septic Drainfield Piping on steep slopes
- Due to the fact that septic tank effluent is not treated to a high level of quality, lateral lines for septic tanks are commonly necessary. A normal septic tank only has a treatment level of roughly 30%, which is not sufficient for most applications. A contemporary sewage treatment plant or aerobic sewage system, according to the contract, has a treatment efficiency of 95 percent or above. Clean and transparent effluent is produced by systems such as the Biocell QuickOne which achieve an even higher treatment level of 98 percent. Having a sewage treatment system installed will often result in an approval from the local environmental agency and building control office to discharge directly into a stream or a waterway. As a result, while a sewage treatment system is more expensive than a conventional septic tank, you save a significant amount of money by not having to construct lateral connections. Even if you do not have access to a stream or watercourse and you need to establish some lateral lines, you may install a lower number of lines after a sewage treatment plant since the effluent is much cleaner and it infiltrates into the ground much more readily after a sewage treatment plant.

Apart from this text (which may be found below), readers interested in septic installation guidance for steeply sloping or rolling sites should study the following articles:
- THE INSTALLATION OF Sewage OR SEPTIC LINES ON STEEP SITES is a term that refers to the installation of sewer or septic line pipes connecting a structure to its septic tank or sewer main on steep sites that slope down substantially between the structure and the septic tank. SYSTEMS DE DOSAGE For hilly sites where the drainfield must be located either uphill or downhill from a septic tank or structure, PRESSURE is a term that refers to pressure dosing systems that may be beneficial for disposing of sewage. GRAVELLESS SEPTIC SYSTEMS – Other gravelless systems are capable of handling mild bends required to follow rolling slope lines
- However, some gravelless systems are not. Sewage pumps, sewage ejector pumps, grinder pumps, effluent pumps, sump pumps, septic pumping stations, and sewer pump alarms are examples of systems that will be required if the building or septic tank is located below the drainfield or sewer main. Installation of septic drainfields on steep or undulating terrain is described in detail in STEEP SLOPE DESIGNS(text found immediately below)
Guide to Installing Steep Slope Septic Drainfield Systems
The sketch at the top of the page illustrates one strategy for installing septic drainfields on a steep or rolling slope. Septic tank and seepage pit systems are seen in the photo above, which is placed in the flat region below the hillside and connected to a sewer line running down the steep slope. The question becomes, however, what to do when the septic effluent absorption system or soakbed itself must be placed down a steep hillside. Here are some details about the product.
- Septic systems with a D-box for steep slopes: When septic effluent is clarified, it is discharged from the septic tank (or an effluent pumping station) and directed into a big distribution box. A larger D-box with more connection ports will be required than those used for a standard flat-area drainfield since each effluent line that will be installed across the hillside will need to be connected directly to the D-box. Separate effluent lines for steep slope septics are required: Individual septic effluent drain lines are connected to the distribution box, and each of these drain lines is directed to a separate gravel trench and perforated drainfield. Feeder pipes for effluent lines in steep slope septic systems include the following: It is not perforated, but rather solid pipe that connects the distribution box to the drainfield trench. Effluent lines for hillside or rolling land drainfields are placed along the slope, not uphill or downhill, and sloping gently (1/8″ to 1/4″ per linear foot) from the inlet end of each drainfield trench to the lowest point of the drainfield trenches.
Installing Septic Drainfield Piping on Steep Slopes Located Downhill from the Septic Tank – Rolling Land
- For steep slope septics, flexible distribution pipe or gravelless systems are recommended: Because flexible effluent lines may be routed in a trench that must be curved in order to remain parallel to the fall line of the slope of rounded hilltops or rolling ground, flexible piping may be more convenient to construct than rigid pipe systems in areas where the land is rolling or contoured. Dosing with high pressure for steep slope septic systems: Septic effluent handling methods, such as pressure distribution systems, may be more forgiving of installation on steep or uneven sloping ground, and they may use rigid or flexible perforated pipe, depending on the application. Pressurized Septic Systems (also known as Pressure Dosing Septic Systems)
- For septic system effluent dispersal, drip lines—which employ flexible distribution piping—might also be effective on some steep locations. Some aerobic systems that dispose of effluent using drip systems or spray systems, or that feed drip irrigation systems, can solve the problem of steep slope septic effluent disposal, according to the manufacturer.

Graywater disposal systems also include designs that can assist with effluent of graywater GREYWATER SYSTEMS are discussed more below.
Why Drainfield Effluent lines need to be properly sloped
Septic drainfields that use gravity to treat and dispose of cleared wastewater effluent must be correctly pitched and never slope too steeply to ensure effective operation. If this is not done, effluent will flow too fast to the low end of the drainfield line and gravel trench, where it is likely to simply break out onto the surface of the land. If you need to build a traditional perforated pipe and gravel trench drainfield on a steep slope, you’ll need to run the trenches parallel to the fall line or down the slope itself, descending down the slope from trench to trench as you go.

Reader CommentsQ A
On the 25th of May in the year 2020, by (mod) – Is it possible to have the leach lines for a septic tank go uphill from the tank? Although it is possible to place the drainfield above the septic tank, an effluent pumping system will be required. This is an excerpt from the previous remark. This is where the leach line will be put, as opposed to the lower level, where the septic system is buried.

If none of these options work, we (and by we, I mean you) may have to resort to a raised bed or mound septic system.
The drain field is located on a level part of a hill with a width of around 60 feet.
Should a french drain be installed in the flat area uphill from a drain field in order to sort of isolate the drain field and make it more or less operate as a mound at that point in time?
Thank you, Kelly.
This will ensure that the bottom of your drain field or effluent disposal system has enough soil beneath it that the affluent does not simply hit rock and flow down The Rock and into the lake.
A septic system is being considered for installation on an island that is largely solidrock (Canadian Shield) and slopes into a body of water (Lake Superior) (5 percent to 25 percent gradient in places).
How dependable would a septic system be under these circumstances and what are the difficulties I should be aware of?
How long do you think this system will be able to work before it breaks down?
What is the highest topographic slope that may be accommodated in a septic field servicing a single family property in Frederick County, Maryland?
Thank you so much for your prompt answer.
Your solution requires me to install six drop boxes across a 100-foot distance!
A sewage pipe that is excessively steep may cause water to flow too quickly, leaving particles behind.
When using a stepped line method, it is preferable to make each turn through a D box to allow for easier cleaning access.
This is my problem: I’m putting a bathroom and kitchenette in my remote 2400 square foot woodworking shop, which I’m now in the midst of constructing.
I work as a carpenter, mason, and builder.
For the pre-existing septic tank, I have around 20′ of fall and approximately 100′ of run.
The house has been put on hold (waiting for more money).
I don’t live on the construction site, and it appears that it will be several years before I can begin construction on the house.
“the sewage line down to the septic tank should be laid out in a step-wise fashion?
Besides being built on granite bedrock, the septic tank and effluent pump to a drain field are situated on the property to fulfill both perc test criteria and to maintain a minimum distance of 100 feet from a river.
When not attached directly to bedrock, frost footings must have a minimum depth of 5′ to be considered.
Another concern is the presence of black water.
There will be a cleanout installed at the point where the pipe breaks through the foundation wall.
Steve, It’s amazing to hear about drainfields that are more than 50 years old and are still in good working order, though I’ve seen a few myself, including a complex system built on an estate around 1920.
When a system is “working,” it means that it appears to be successfully disposing of effluent – that is, there are no wet spots on the ground.
Nevertheless, in the absence of any failure data, almost no one would dig up and interfere with a drainfield.
It would be beneficial to include more specifics in this section.
Many of these were placed as long as 50 years ago and are still in good working order.
Diverse considerations, including the existence of impermeable strata, seasonal ground water, and slope stability, must be given careful attention.
This was quite beneficial.
It was, without a doubt, pricey.
I figured I’d best include this: Because the drainfield site will be well down-slope from the construction site and tank, a gravity-fed system or a syphon system may be used.
Standard drain fields are not permitted on slopes greater than 25 percent in my county.
This is excellent information.
I have a building site that is on a 24 percent to 30 percent slope. STEEP SITE INSTALLATION OF A SEWER OR SEPTIC LINE CONTINUES READING Alternatively, choose a topic from the closely related articles listed below, or browse the entireARTICLE INDEX. Alternatively, consider the following:
Steep Slope Septic System Articles
- By (mod) – posted on 2020-05-25 When installing a septic system, can the leach lines be run uphill from the septic tank? Although it is possible to have the drainfield above the septic tank, an effluent pumping system will be required. According to the previous comment. It will be installed here, as opposed to where the septic system will be buried in the lower level. As soon as you see the house, it will be located on top of this embankment on the right side of the house. Can a septic system be installed at ground level while the leach area is installed on an embankment behind the house? In this case, the embankment height corresponds to the top of the roof of the single-story house that is being constructed. Due to the fact that it is not built at a level like a typical septic system, will there be issues with this setup and how long will a pump last for this system. Because the leach area is located on a steep slope away from the septic system, how often will the pump need to be replaced and how expensive will this process be in the long run of owning your home? Can a septic system be installed at ground level while the leach area is installed on an embankment behind the house? In this case, the embankment height corresponds to the top of the roof of the single-story house that is being constructed. Due to the fact that it is not built at a level like a typical septic system, will there be issues with this setup and how long will a pump last for this system. Because the leach area is located on a steep slope away from the septic system, how often will the pump need to be replaced and how expensive will this process be in the long run of owning your home? That is, in fact, the subject of the article that appears above on this website. Essentially, you must maintain a slope of 1/8 to 1/4 inch per foot of horizontal run in order to prevent all effluent from immediately rushing to the end of the system and overloading it there. Having a leachfield that has some incline to it, are there any potential issues? Steve We are therefore discharging sewage into the environment during the winter
- I agree that diverting surface runoff away from the drainfield may be a viable solution. Both a swale to intercept actual surface runoff and an excavation trench with a depth greater than 24 inches may be required in some situations “buried below the bottom of the drainfield trenches in order to capture groundwater and transport it away from the field. Obtain daylight away from the field area in order to transport groundwater and surface water to it. It is possible that we (or you) will have to resort to a raised bed or mound septic system if none of the above methods proves effective for us. There is an appearance that runoff from a steep hill, including seep springs, is overflowing into the drain field, particularly during the winter months. On a hillside about 60 feet wide, there is a flat area where the drain field can be found. The problem is not an issue during the summer months. Is it a good idea to put a french drain just beginning in the flat uphill from the drain field in order to sort of isolate the drain field and make it more or less act as a mound at that point? Because the drain field is on the downhill side, runoff from the field is easily diverted away. Kelly has been extremely helpful. You will need enough space to ensure that your septic system meets the setback requirements from the water’s edge, and you will almost certainly need to bring in soil in order to construct a sufficiently elevated Mound system so that the bottom of your drain field or effluent disposal system has enough soil beneath it that it is not simply going to hit rock and then send the affluent Down The Rock and into the lake. Consider the possibility that, wherever you live, there will be an authority that will need to approve the specific septic design, necessitating the hiring of a septic design engineer who is familiar with both local regulations and the soil conditions on your Island in order to get the job done. A septic system is being considered for installation on an island that is largely solidrock (Canadian Shield) and slopes into a body of water (5 percent to 25 percent gradient in places). Setbacks from the lake would be between 30 and 40 meters in length according to the size of the lot in question. How dependable would a septic system be under these circumstances and what are the difficulties I should be mindful of? Attempting to do so, do you think, is a mistake? How long do you think this system will be able to keep up its performance before failing? Thanks. When it comes to a septic field that serves a single family property, what is the greatest topographic slope that can be approved in Frederick County, MD? What is the distance between each agg line? Your rapid response has been greatly appreciated – Just a thought: why would I install D Boxes when I can simply build a second cleanout in the middle of the run, which is less expensive and less obtrusive? I’m going to have to install six drop boxes over 100′ using your approach. That appears to be excessive, costly, and requiring a great deal of upkeep in my opinion. A sewage pipe that is excessively steep may cause water to flow too quickly, resulting in particles being deposited in the sewer. Despite this, I’ve seen straight shot steep lines from home to tank that have served their purpose for decades without fail. Each pass through a D box, which allows access for cleaning, will improve the effectiveness of a stepped line approach. Amazing website, I must say. What’s the problem? I’m in the process of building a 2400 square foot woodworking shop in the country, and I’m putting a bathroom and kitchenette (myself – for myself). My trade is that of a carpenter, mason, and builder, amongst other things. Even though plumbing is not my field of expertise, I have some basic knowledge of the profession. For the pre-existing septic tank, I have around 20′ of fall and about 100′ of run. In order to accommodate a dwelling, the tank was installed. It has been decided to put the house on hold (waiting for more money). The store has received permission to utilize the tank and field. As of today, it appears that it will be several years before I am able to begin construction on the site. Is it possible for me to run a four? “sewage line down to septic tank in a step-by-step fashion? In other words, horizontal runs number one “Continue in this pattern for approximately 15 feet, then drop to around 3 feet vertical drops, and continue in this manner until I reach the tank? Besides being built on granite bedrock, the septic tank and effluent pump to a drain field are situated on the property to fulfill both perc test criteria and the need of being at least 100 feet away from a river. It is mostly clay on granite, with a 3′ layer of clay on top. When not linked directly to bedrock, frost footings must have a minimum depth of 5′. A professional builder’s standard operating procedure is to run two (2) “over their water pipes with polystyrene Another problem is the presence of black water. When venting between the shop and the tank, will I need to vent halfway? There will be a cleanout installed at the point where the pipe enters the foundation wall. Those who can provide me with good practical aid will be much appreciated, and I will express my gratitude to them. Steve, Hearing about drainfields that are 50 years old and still in good functioning order is incredible, though I have seen a couple myself, including one that was erected on an estate in 1920 and is rather complicated. But I’d be on the lookout for anything unusual or suspicious. When a system appears to be “functioning,” it signifies that the effluent is being properly disposed of – that is, there are no damp spots on the surface. It is possible for a septic system to fail in a more covert manner, such as by overflowing onto an adjacent property’s yard, stream, or underground aquifer. Without any failure data, however, it is unlikely that anybody would dig up and interfere with a drainage system. Can you tell me more about the specific concerns you’ve learnt about septic systems on steep slopes? More specifics would be beneficial in this situation. It is possible to find septic leach fields with slopes of up to 80 percent in this area, and there are other leach fields with slopes as low as 50 percent that use regular leach trenches as well. Many of these were placed as long as 50 years ago and are still in good working order now. Site specific considerations must be taken into consideration when determining whether a steep slope is appropriate for septic effluent distribution. Diverse considerations, including the existence of impermeable strata, seasonal ground water, and slope stability, must be given due consideration. Please accept my thanks. I found this to be quite beneficial. B Page We were able to satisfy the code officials on a steep slope in Virginia many years ago by combining the type of across-slope trenching system you see at the top of the page with the sculpting of the slope into a terraced hill
- The wider flat areas of the terraced surfaces provided plenty of room for the drainline trenches. Of course, it was a costly endeavor. The excavator had to bulldoze what amounted to a roadway that zigzagged down the steep slope, and then the excavator had to operate backwards from the bottom up so that there was no concern about equipment running over finished drainfield trenches during the excavation. I thought it would be a good idea to provide the following information: Due to the fact that the drainfield location will be considerably down-slope from the construction site and tank, either gravity fed or a syphon system might be utilized. Anyone have any more advice for septic system design for steep slopes greater than 25%? Standard drain fields are prohibited on slopes more than 25 percent in my county code. Do you have any examples of designs that have been effective on these sorts of slopes? This is really useful information. Thanks.

May you tell me where I can receive help with local installation code, system designs, and technical concerns about products? Several installation choices and criteria are controlled by municipal rules that have been established by the health authority in your region. When in doubt, consult with your local health agency for specifics, and then adhere to their code recommendations as best you can. The Technical Services staff at Infiltrator Water Technologies may be reached at 1-800-718-2754, if you have any queries about design or installation that are not addressed here.
- A variety of septic leachfield and leach bed applications can benefit from the usage of EZflow.
- This comprises trenching, bed construction, and raised mound construction.
- How much of a reduction in the size of the leachfield can I expect if I install EZflow?
- The size of a wastewater treatment system is often determined by a mix of criteria, including the soil type and amount of wastewater to be treated (normally estimated using number of bedrooms).
- Check your local health codes for information on what is required in your region.
- Local regulations govern the spacing requirements for trenches, so check with your local health authority for more information.
- Infiltrator Water Technologies recommended that there be no gap between the sides of bundles when used in beds.
The majority of health rules prohibit the installation of septic leachfields beneath impervious surfaces such as roads and sidewalks.
Consult your local health department for information on the exact codes that apply in your region.
When it comes to minimum and maximum system cover, what is EZflow’s specification?
In a trench system, the maximum amount of cover allowed above EZflow is 96 inches.
Always check with your local health codes to see if there are any special requirements for coverage.
Yes. When it comes to contouring around existing impediments, EZflow has nearly limitless capabilities. In order to prevent soil from entering EZflow through the netting, what should be done? The dirt is prevented from entering the bundles by a geotextile mesh that is woven into the netting.

Each of these statements is theoretically valid, however there are more than eight different types and configurations of OWTS to choose from.
A soils morphology test is required in order to correctly design an OWTS system and submit a system permit application for the system.
When designing an OWTS system, soil conditions are critical since the soil serves as a filter, exchanger, and absorber in addition to other functions.
A septic tank offers initial treatment by separating particles from wastewater, ensuring that effluent entering the soil is purified before it is released into the environment.
In soils that are unable of supporting a simple OWTS system, a septic tank and surface lagoon can be used as an alternate solution.
Lagoons are a more cost-effective alternative to more complicated systems because of their size.
The system is comprised of a septic tank, a pumping chamber for pressure dosing, and a soil distribution piping system with a small diameter pipe diameter.
a few quick facts According to the Environmental Protection Agency, private on-site waste treatment systems are used by 20 percent of all houses in the United States to handle their garbage.
Septic or decentralized treatment systems are used to service about one-third of all new developments and single-family dwellings. Septic systems provide service to more than 60 million people in the United States.
