Table on Septic Systems and Drinking Water

Bathrooms and Kitchens |
Wastewater is the water that comes from toilets, sinks, showers, and other appliances, and it can be damaging to human health. If wastewater gets into touch with your drinking water well, it can include hazardous bacteria, viruses, and nutrients that can make you sick.
Make sure your septic system is appropriately treating the wastewater and that your drinking water well is at the proper distance (setback) from your and your neighbor’s systems. Other chemicals or drugs should not be flushed down the drain or toilet since they may contaminate your drinking water supply. |
Septic Tank |
Your home’s waste water drains into a septic tank via a drainage line. Sewage is collected and treated in the septic tank, which is an underground, watertight container. When fat, oil, and grease are added to the mix, they float to the top (scum).
Sludge is broken down by microorganisms, which also eliminate some of the pollutants found in wastewater. In order to ensure that your septic tank is running properly, it should be repaired and pumped often. |
Drain Field |
A drainfield is indeed a deep, enclosed trench dug in your garden’s soil.
The septic tank’s partly cleaned effluent flows out all the drainfield, filters downward through to the earth, and into the groundwater. The drainfield will flood whether it is overwhelmed with liquid or clogged with solids, causing sewage to surface in your lawn or right back inside the house. |
Wastewater Treatment in Soil |
Most bacteria and viruses (also known as pathogens) are removed as well as some nutrients when wastewater is filtered through the soil.
While soil can cure a variety of pollutants, it cannot eliminate them altogether (e.g., medicines, some cleaning products, other potentially harmful chemicals). Untreated wastewater may pollute your drinking water if it collects in the yard due to an unsecured well cover or fractures in the well casing. Because medicine and chemicals might pollute your drinking water, it’s vital to avoid flushing them into your wastewater. |
Water Table |
Whenever you drill a hole through into earth, you’ll find the water table where you would have struck water. |
Groundwater |
Groundwater is the water below the water table.
Any residual pollutants discharged from the septic system are captured by groundwater running beneath a drainfield. If a drinking water well is in the route of groundwater flow under a septic system, it is more likely to get polluted. |
Drinking Water Well |
To pump water to the surface, a drinking water well is drilled or excavated into the groundwater.
deep wells that are further away from a septic system and are not in the course of the septic system’s groundwater flow are the least likely to be polluted. Drinking water wells should be checked on a regular basis to verify that the water in your house is safe to drink. |
Setback Distance |
A certain horizontal distance (or setback) between a septic system and a drinking water well is required by most states and municipal governments.
If you reside in a sandy or porous area, you may want to put your well further away than the minimum distance necessary. The farther a well is from a septic system, the less likely it is to get contaminated. |
Could My Well Be Affected? |
Under some circumstances, your septic system might pollute your drinking water well or a neighbour well.
Remember to test your well’s drinking water on a regular basis and take corrective measures if necessary. The farther away your well and septic system are, the lower the danger of pollution to your well. If the well is in bedrock or below a specified layer of silt or clay, the deeper it is. When your septic system is regularly drained and maintained. Your well is at a higher risk of contamination: if the well is shallow and surrounded by porous soil if the septic system is downgradient from the well (i.e., if the groundwater flows from the septic system towards the well). if there are a lot of residences with septic systems close to the well if the well and/or septic system were built or maintained improperly (i.e., contaminants can enter a cracked drinking well casing from ground or surface water). Returning homeowners may have concerns about their drinking water and septic systems if their homes were damaged by fire. People who have private wells should be worried about the safety of the water they drink. To verify the water is safe, get it analysed at a recognised environmental testing laboratory. |

Septic System |
Drinking Water System |
| A septic tank that is watertight. | Proper well construction and upkeep. |
| A soil treatment area is generally a drainfield or a mound with adequate soil conditions for wastewater treatment. | Proper installation, back syphon protection, and maintenance of distribution systems, including water treatment equipment, water lines, and fixtures. |
| Proper operation entails using less water and cleansers. | Maintaining separation distances from contaminating sources. |
| Maintaining the proper level of care requires a review at least every three years. | Fixtures and pipelines that are leaking or dripping |
| When a septic system fails, sewage can back up into the residence or rise to the surface. Failing systems are more prone to leak CECs as well as potentially hazardous bacteria, viruses, and other microbes into the environment. | Wells in pits
Uncased shallow wells. Unused wells that have not been sealed. Wells with damaged casing or apertures
|
| There may be cracked tanks, seepage pits, and drywells since the tanks aren’t waterproof. | Cross connections between water lines and possible sources of contamination without a protective plumbing device or an air gap |
| Under the soil treatment area, there aren’t the necessary soil conditions. | Contamination sources that are stored or mismanaged near your well |
| A qualified septic system maintainer/pumper should inspect and clean septic tanks at least once every three years (state law).
Every year, go for a walk around the drainfield to make sure it’s in good working order. Make sure the soil treatment area isn’t too compacted. Keep plants in good shape. |
If a baby will drink (dry formula), the water should be tested for manganese at least once.
Inspect your wellhead on a regular basis. Any fractures or holes in the well casing, corrosion, loose wires, or soil settling are examples of damage. Is the well cap firmly connected to the well casing? Is it damaged or missing? Connections: Protect your well by ensuring that the electrical conduit and other connections are waterproof. |
| Leaky faucets and toilets should be repaired (or replaced).
In the toilet, only human waste and toilet paper should be flushed. Wipes, feminine products, cotton balls, and other items are prohibited. Cleaners should be used with caution: Use only as much cleaning as you need, and stay away from hazardous substances labelled “poison or danger.” Antibacterial products should not be used. They also destroy beneficial microorganisms. Use local take-back programmes to properly dispose of hazardous trash and unwanted medications. |
Keep the top of the well at least one foot above the ground.
Use, store, or dispose of possible contaminants away from your well. Unused wells should be sealed. Keep water treatment equipment in working order. Look for and fix leaks and drips.

Frequently Asked Questions (FAQs):
High Water Table Septic Systems
And you work your way out let the water fill the sump pump it and pump it out certain your ‘suck. Start on the discharge. Line that’s what you want have a discharge line and a pump in pumping.
Septic Systems for High Water Table Areas
An Alternative Septic System That Features an Intermediary Filtration System Can Help Address Problems Associated with a High Water Table. the Most Common Type of Filtration System Used Is a Sand Filtration System. Wastewater Passes Through a Sand Filter After the Septic Tank Discharges It.
Septic Systems and Drinking Water
Septic systems provide wastewater treatment for many homeowners who also often get their drinking water from private wells. If a septic system is not working properly or is located too close to a drinking water well, contaminants from the wastewater can end up in drinking water.
Septic Tank Drinking Water
Make sure that your downpipes and drains that carry rainwater are not connected to your septic tank. This could wash out the contents of the tank before it is broken down, and could cause pollution and health hazards.
