Maintaining Your Septic System

Eliminating unnecessary sources of surface water will help maximize your septic system's life. The disposal field is designed to treat a specific amount of wastewater each day. This is based on the number of bedrooms in the home and the number of occupants. Check to see if water from eavestrough, grass watering, plowed snow, parking lot drains or other sources is not draining on top of your septic field. A one inch rainfall will add 27,145 gallons of water to one acre of ground. The runoff from your roof can be as much as 400 gallons. There should be no need to water or fertilize the septic field.
Household water conservation will reduce the strain on the sewage disposal system and prolong it's life. Leaky toilets, faucets, and extended showers can easily tax the system beyond it's limits. Water softener recharge water can be diverted to a separate disposal area since it is not wastewater. Laundry can be spread out over several days to minimize the daily surge of wastewater to the system. Low flow shower heads and faucet aerators, along with low capacity toilet tanks can help lower the amount of wastewater a system needs to handle.
Landscaping the septic field should merely be grass or small vegetation. Large bushes or trees will clog the system's piping with roots. Grass will take up some moisture, as well as nutrients from the field. Never pave over a field, nor park heavy vehicles or machinery on top the system.
Shoreline residents need to pay particular attention to their wastewater disposal system due to the unique situation they have. Often, the soils around lakes and streams are not as well suited to sewage disposal as upland sites are. The disposal system should be situated as far away as possible from surface water (100 feet as per the Sanitary Code). Water conservation practices are especially important for these residents. The saturated soils encountered near lakes and streams will facilitate the movement of nutrients and contaminants toward the surface water. Many times, the system will appear to be working fine, but in reality, may well be leaking contaminants into the lake, pond, or stream. Look for signs such as excessive weed growth in isolated areas, an increase in infections or illnesses from swimmers, or unpleasant odors near the shoreline.
