For example, don t run the dishwasher, do laundry and take showers all in a short period of time. Give the system a chance to work between large doses of water. This allows solids to settle in the septic tank and time for the bacteria in the tank and the soil to do their work. Don t put chemicals into your septic system. Household chemicals kill the good bacteria that help your septic system work and can contaminate the sludge, making sludge disposal more dangerous.
Chemicals also travel through the disposal field and contaminate ground and surface water.
Don t use the toilet as a wastebasket. Non- biodegradable materials such as diapers, sanitary napkins and cigarette butts will not break down in a septic tank. Flushing them down the toilet will cause the septic tank to fill faster and adds to litter problems when septage is spread. Avoid putting large amounts of fats and grease into your septic system. Don t use a garbage disposal .
