It’s “ten feet”. That’s the suggested distance if a potable water line and a sewer line are parallel to each other; the distance is measured horizontal from edge to edge.
- • The septic system needs to be at least 200 feet from any public potable wells that are currently being used to service non-residential or residential establishments that have a greater total daily sewage flow of 2,000 gallons or more. • The OSTDS is not allowed to be placed under any buildings.
How far should a septic tank be from a water source?
The distance between the septic tank and borewell is 15 ft and the dimension of the septic tank is 11X6X7 ft.
What would be the minimum distance between sewer line and water lines?
The underground water service pipe and the building sewer or drain shall be kept at a sufficient distance not less than 2 meters apart so as to prevent contamination of water.
How far is ad box from septic tank?
The D-box is normally not very deep, often between 6″ and two feet to the top of the box. You may also see a pattern of parallel depressions, typically about 5 feet apart, that mark the individual drainfield leach lines. The D-box will at or near end of the drainfield area that is closest to the septic tank.
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 far apart are leach field lines?
The minimum separation between the bottom of any leaching device and seasonally high groundwater shall be: 5 feet where the leaching device is between 50 and 100 feet from a stream, spring, or other waterbody.
Can you run sewer and water in the same trench?
PLUMBING (SEWER AND WATER) Water pipes shall not be run or laid in the same trench as building sewer or drainage piping constructed of clay or materials that are not approved for use within a building unless the following conditions are met (CPC 609.2):
Are water and sewer lines the same?
In your home the sewer lines are referred to as “building drains” and outside the home as “house drains”. Or from a shower or lavatory drain. All of these different types of waste water can be classified as sewage and are required by State Plumbing Codes to be transmitted for treatment by the sewer lines.
What is the minimum vertical separation between a water service pipe and a sewer pipe regardless of soil type?
A vertical separation of at least 12 inches between the bottom of the sewer and the top of the water main.
How do you find a buried septic tank?
Tips for locating your septic tank
- If the septic tank lid is underground, you can use a metal detector to locate it.
- You can use a flushable transmitter that is flushed in the toilet and then the transmitter is tracked with a receiver.
Does my septic system have a distribution box?
If your layout consists of a rectangular and level drain site, your distribution box is likely to be located near the edge of the drain field, closest to the septic tank. You can also look for a depression in the ground between the septic tank and drain field a couple of feet in diameter.
Is a septic distribution box necessary?
The distribution box is a major part of the septic system being able to function properly is very important. If the distribution box isn’t working the right way you will soon be dealing with leach field failure.
What can I use instead of a septic tank?
Alternative Septic Systems
- Raised Bed (Mound) Septic Tank Systems. A raised bed drain field (sometimes called a mound) is just like what it sounds.
- Aerobic Treatment Systems (ATS) Aerobic systems are basically a small scale sewage treatment system.
- Waterless Systems.
What is the alternative to a septic tank?
Mound systems work well as alternatives to septic tanks when the soil around your home or building is too dense or too shallow or when the water table is too high. Although they are more expensive and require more maintenance than conventional systems, mound systems are a common alternative.
What is the difference between a septic tank and a leach field?
The septic tank stores solid waste products that are not reduced to liquid effluent until you have them pumped out and disposed of properly. The leech field is a series of perforated pipes that provide an effective means for disposing of contaminates without endangering animals or contaminating the ground water.
What is the recommended distance between a private water well and a septic tank?
| What should not be flushed through a septic system? |
- Grease, oils, or fats from cooking
- Pesticides
- Paints and paint thinners
- Solvents
- Disinfectants and other household chemicals
Setback Distance From Septic to Drinking Water Well – Drinking Water and Human Health
To treat and dispose of wastewater, or sewage, many rural people install on-site wastewater treatment systems (also known as individual septic systems) on their property. Among the impurities found in residential wastewater include disease-causing bacteria, contagious viruses, common household chemicals, and excess nutrients. By designing, installing, and maintaining a septic treatment system appropriately, the danger of contaminating the drinking water supply with these toxins is reduced significantly.
- A septic tank and soil absorption system is a wastewater treatment technology that is allowed in a number of jurisdictions.
- Alternative technologies may also be permitted in some cases.
- When it comes to protecting a private drinking water supply from pollution, while minimal setbacks are important, higher separation lengths are frequently preferable in many cases.
- The minimum setback requirements in Nebraska will be utilized as an example.
- A residential lagoon must be at least 100 feet away from a private drinking water well in order to be allowed to operate.
- Always verify your local legislation to ensure that the minimum setback distances are met in your neighborhood.
Septic Systems and Drinking Water
| 1. Bathrooms and Kitchens | Water from toilets, sinks, showers, and other appliances is called wastewater and can be harmful to human health. Wastewater contains harmful bacteria, viruses, and nutrients that could make you sick if it comes in contact with your drinking water well. Make sure the wastewater is properly treated by your septic system and that your drinking water well is located at the appropriate distance (set back) from your and your neighbor’s system. Avoid flushing other chemicals or medications down the drain or toilet since they could also contaminate your drinking water well. | |
| 2. Septic Tank | Wastewater generated in your home exits through a drainage pipe and into a septic tank. The septic tank is a buried, water-tight container that holds wastewater for separation and treatment. The solids settle to the bottom (sludge) and fats, oil and grease float to the top (scum). Microorganisms act to break down the sludge and destroy some of the contaminants in the wastewater. Your septic tank should be serviced and pumped on a regular basis to make sure it’s working properly. | Learn more about how your septic system works. |
| 3. Drainfield | The drainfield is a shallow, covered trench made in the soil in your yard. Partially treated wastewater from the septic tank flows out through the drainfield, filters down through the soil and enters the groundwater. If the drainfield is overloaded with too much liquid or clogged with solids, it will flood and cause sewage to surface in your yard or back up into your home. | |
| 4. Wastewater Treatment in Soil | Filtering wastewater through the soil removes most bacteria and viruses (also known as pathogens) and some nutrients. While soil can treat many contaminants, it cannot remove all of them (e.g., medicines, some cleaning products, other potentially harmful chemicals). If untreated wastewater surfaces in the yard, wastewater may contaminate your drinking water through an unsecured well cap or cracks in the well casing. It’s important to avoid flushing medication and chemicals into your wastewater since it could contaminate your drinking water. | |
| 5. Water Table | The water table is found where you first hit water if you dig a hole into the ground. | |
| 6. Groundwater | The water below the water table is called groundwater. Groundwater flowing underneath a drainfield captures any remaining contaminants released from the septic system. A drinking water well is at greater risk of becoming contaminated if it is in the path of groundwater flow beneath a septic system. | |
| 7. Drinking Water Well | A drinking water well is drilled or dug into the groundwater so water can be pumped to the surface. Deep wells located farther away from a septic system and not in the path of the groundwater flow from the septic system are least likely to be contaminated. Drinking water wells should be regularly tested to ensure your home’s water is safe to drink. | Learn about private water wells. |
| 8. Setback Distance | Most states or local governments require a specific horizontal distance (or setback) between a septic system and a drinking water well. If the soil where you live is sandy, or porous, you may want to place your well farther away than the minimum required distance. Contamination is less likely the farther apart a well is from a septic system. | Consult your local health department about required setback distances in your area. |
| 9. Could my well be affected? | Your septic system could contaminate your drinking water well or a nearby well under certain conditions. Remember to test the drinking water from your well regularly and take corrective action as needed.The contamination risk to your well is LOWER: |
- The greater the distance between the well and the septic system
- The greater the depth of the well and whether it is on bedrock or below a specified layer of silt or clay
- And the greater the distance between the well and the septic system If your septic system is pumped and maintained on a regular basis, you can avoid this.
The following factors increase the danger of pollution to your well:
- The well is at a shallow depth and in permeable soil
- It is downgradient of the septic system (i.e., groundwater flows from the septic system towards the well)
- There are many homes on septic systems near the well
- Or the well and/or septic system have been poorly constructed or maintained (i.e., contaminants can enter a cracked drinking well casing from groundwater or surface water).
| Learn other ways to keep your private well safe from possible sources of contamination. |
How Much Distance Should Be Between My Septic Tank and My Well?
If the well is at a shallow depth and in permeable soil; if the well is downgradient of the septic system (i.e., if groundwater flows from the septic system towards the well); if there are many homes on septic systems near the well; or if there is poor construction or maintenance of the well and/or septic system (i.e., contaminants can enter a cracked drinking well casing from ground or surface water);
Recommended Distances Between WellsSeptic Components
As a result of local rules or soil conditions, local authorities may mandate greater distances between a well and a septic component than those suggested by the Environmental Protection Agency. When property limitations or elevation changes are involved, components can be brought closer together in other circumstances. The following are the regulations for distances between wells and septic components in the state of Maryland for wells that are intended for water distribution: d) 100 feet from identifiable sources of contamination and designated subsurface sewage disposal areas if the proposed well will utilize an unconfined aquifer as a water supply source; e) 50 feet from identifiable sources of contamination and designated subsurface sewage disposal areas if the proposed well will utilize a confined aquifer as a water supply source; and f) 50 feet from any sewage gravity or force main, except as provided in B(3) of this regulation.
The Maryland Department of the Environment’s Regulation of Water Supply, Sewage Disposal, and Solid Waste, Chapter 04: Well Construction, is the source for this information.
Contamination of a well may occur if the distance between a septic system and a well is insufficient, or if there is a leak or a breakdown in a septic system’s component.
Possible Contaminants from Septic Systems
When a well is located too close to a septic system or other source of wastewater, a range of pollutants, such as the following, might infiltrate your well water:
- Salmonella and E. coli are examples of bactria. Viruses, such as norovirus or hepatitis A
- Bacteria
- And parasites detergents and soaps that include phosphorus. Chemicals derived from paint, drain cleaners, and other common home items
- Heavy metals, iron, and copper are examples of such materials.

Septic System Information and Care
When municipal sewer service is not available, a septic system that has been properly constructed and maintained is an excellent option for treating wastewater and protecting groundwater quality. A typical septic system is comprised of two key components: the septic tank and the drainfield (or leach field). Waste from toilets, sinks, washing machines, and showers is channeled into a septic tank, which is a holding tank that is typically constructed of pre-cast concrete or fiberglass and is proportioned according to the projected wastewater flow from a given-sized house or commercial establishment.
- In the first stage of wastewater treatment, anaerobic bacteria (bacteria that can survive in an oxygen-free environment) break down solids into liquids and generate gas that is vented through the building’s plumbing vent stack.
- The lack of oxygen inside the septic tank also has the added benefit of deactivating some of the disease bacteria that are prevalent in sewage.
- Because it allows aerobic (oxygen-using) bacteria to continue deactivating the disease germs that remain in the wastewater, the drainfield serves as a secondary treatment facility for sewage.
- Evaporation of water also occurs through the layer of soil that surrounds the drainfield.
- That way, enough permeable or unsaturated soil is available to filter the wastewater before the remainder of it gets into the groundwater table and underlying aquifer.
- In certain instances, modern wastewater treatment systems that “aerate,” or add oxygen to the wastewater, may be necessary to treat the effluent.
Others are equipped with chlorinating chambers or peat moss-based filtering chambers, which kill disease germs before they may infiltrate into groundwater supplies.
Septic System Care
Don’t flush cigarette butts, tampons, condoms, or any other indigestible things down the toilet or down the sink drain. Consequently, the exit filter or drainfield will become clogged. Never throw grease down the drain since grease cannot be digested by the septic system and will cause it to become clogged! rather than dumping it in the garbage, pour it into an empty container or bottle and throw it away. Make sure you don’t use excessive amounts of bleach or other cleaning agents in your septic tank since doing so will interfere with the bacterial operation inside the tank.
- Instead of doing numerous loads of laundry back-to-back, stretch your wash loads out over the course of the week to reduce the amount of water that the septic system has to treat (a normal wash load consumes between 60 and 90 gallons each load!).
- Roots from trees and plants will grow into the drainlines and cause them to get obstructed.
- Driving over your drainfield can cause the pipes to become crushed or the dirt surrounding them to become compacted, and driving over your septic tank can cause the lid to fracture or even fall apart!
- Consider the installation of water-saving showerheads, toilets, and other water-saving appliances in your home.
- Septic tanks should be pumped out every four to five years, according to the Florida Department of Health, in order to prevent the buildup of sludge in the tank over time.
- Stoppages and overcrowded drainfields are caused by leaking toilet flapper valves, which can allow hundreds of thousands of gallons of waste water to enter your septic system each day.
- In addition to providing you with many useful suggestions and information, our Environmental Health Professionals can also assist you extend the life of your existing septic system.
The Ins and Outs of Septic Systems in Pennsylvania
Septic systems on private land are used by approximately 26% of Pennsylvania houses for the treatment of domestic sewage. The majority of these residences also have their own private well for drinking water. If you have a septic system, be sure to operate it properly! If you understand how your system operates and how to maintain it, you will be able to do the following:
- Safeguard your drinking water supply and your health
- Maintain the longevity of your system—and prevent spending thousands of dollars for a new system
- Protect the value of your home
- And contribute to the protection of Pennsylvania’s groundwater, streams, rivers, and lakes
- And
Because of Pennsylvania’s geology, soils, land development patterns, and outdated septic systems, there is a danger that poor septic systems may contaminate our groundwater and surface waters—our streams, rivers, and lakes—as well as our groundwater and surface waters Surface waters that have been polluted with viruses and bacteria from sewage pose a greater risk of swimmers being ill with eye and ear infections, acute gastroenteritis, hepatitis, and other infectious disorders.
It is possible that groundwater contamination will poison your own and others’ drinking water supplies, resulting in the transmission of illness to humans and animals.
In 2020, the Pennsylvania Department of Environmental Protection stated that septic system failure was responsible for 202 impaired stream miles and 3,192 damaged lake acres in the state.
Septic system maintenance should be performed in accordance with industry standards to preserve your health, your money, and Pennsylvania’s waterways.
Who Has Oversight of Your Septic System?
In Pennsylvania, local governments (for example, boroughs and townships) are responsible for ensuring that private septic systems with a capacity of 10,000 gallons or less comply with Department of Environmental Protection (DEP) regulations. In the event that you have any queries regarding an existing septic system on your land, or about the construction of a new system on your property, you should contact your local government office first. Many towns have a Sewage Enforcement Officer who ensures that all septic systems are correctly sited, permitted, and inspected throughout their installation to verify that they follow all regulations.
Soil Is Your Best Friend: How Your Septic System Operates
Individuals with private septic systems of 10,000 gallons or less are responsible for ensuring that they comply with Department of Environmental Protection (DEP) regulations in Pennsylvania. The first port of call should always be your local government agency if you have any inquiries regarding an existing septic system or about installing a new system on your property. Local Sewage Enforcement Officers are employed by many communities, and they are responsible for ensuring that all septic systems are properly sited, permitted, and installed according to regulations.
Keep Things Moving Underground
It is believed that the typical lifespan of a septic system is between 15 and 40 years, although it may live much longer if it is properly maintained. Maintaining your septic system is similar to changing the oil in your automobile. It is a low-cost investment compared to the high cost of constructing a new system, which may cost up to $15,000 and more. Don’t overburden the commode with your thoughts when you’re at the sink. Take into consideration what you flush down the toilet and down the sink.
It is best to avoid utilizing common household objects that might clog your system or kill the bacteria underground that are necessary for wastewater treatment.
- D diapers, baby wipes (including those labeled as “flushable”), cat litter, cigarettes, coffee grounds, fats and grease, solids (including feminine hygiene items), and prophylactic devices are all examples of “system cloggers.” “TreatmentKillers” include household chemicals, gasoline, oil, pesticides, antifreeze, paint, and excessive concentrations of anti-bacterial soaps and detergents, among other things.
Don’t put too much pressure on your drain. The less water that you use, the less work your septic system needs to do to keep up with you. Use water-based appliances in small batches, install high-efficiency plumbing fittings, and address any leaks that may exist in your house. Protect your playing field. Keep anything that weighs more than your lawnmower away from your drainage field. Rain and surface water should be diverted away from it. Root clogging in the drainfield might cause the system to fail, therefore avoid planting trees or shrubs in close proximity to the drainfield.
It should be safeguarded and regularly inspected.
According to Pennsylvania laws, this should be done whenever the tank is more than one-third full of solids or scum.
Inspections and pumps may be required under the terms of your local sewage management program, which may be more strict.
For further information, contact the Sewage Enforcement Officer at the local government office where you live. It is important to be aware of the following warning signals of a failing septic system:
- Backing up or bubbling of wastewater into residential drains
- There is an unpleasant smell, or there is some black sludge surrounding the septic tank or drainfield. In the vicinity of your drainfield, you may notice bright green vegetation or spongy conditions.
If your sewage system is not operating properly, contact your local Sewage Enforcement Officer right away. It is important to respond quickly since the less pollution that occurs, as well as the lower the expense of repair work, the better. Your septic system will serve your house and contribute to the protection of Pennsylvania’s waterways for many years to come if it is operated and maintained properly.
