Water usage is also an important aspect of the maintenance of your septic system. Systems are generally designed based on each occupant using 75 gallons of water per day. A single leaky toilet can waste as much as 200 gallons of water per day.
Doing all the household laundry in one day might seem like a time saver, but it could be harmful to your septic system. Doing load after load does not allow your septic system to enough time to adequately treat wastes and could flood your drainfield. Energy Star clothes washers use 35% less energy and 50% less water than standard models.
Non-biodegradable items should not be flushed down your toilets. This includes dental floss, feminine hygiene products, diapers, baby wipes, cigarette butts and other items that can clog and potentially damage septic system components if they become trapped.
Flushing or pouring household chemicals, pesticides, or paint down the drain can stress or destroy the biological treatment taking place in the system and could potentially contaminate surface waters or groundwater. Kitchen garbage disposals should be used in moderation as they increase the volume of solids needing to be digested in the septic tank.
