Use Water Efficiently
The average indoor water use in a typical single-family home is nearly 70 gallons per individual, per day. Just a single leaky or running toilet can waste as much as 200 gallons of water per day.
All of the water a household sends down its pipes winds up in its septic system. The more water a household conserves, the less water enters the septic system. Efficient water use improves the operation of a septic system and reduces the risk of failure.
EPA’s WaterSense program has many simple ways to save water and water-efficient products.
High-efficiency toilets.Toilet use accounts for 25 to 30 percent of household water use. Many older homes have toilets with 3.5- to 5-gallon reservoirs, while newer, high-efficiency toilets use 1.6 gallons of water or less per flush. Replacing existing toilets with high-efficiency models is an easy way to reduce the amount of household water entering your septic system.
Faucet aerators and high-efficiency showerheads.Faucet aerators, high-efficiency showerheads, and shower flow restrictors help reduce water use and the volume of water entering your septic system.
Washing machines.Washing small loads of laundry on your washing machine’s large-load cycle wastes water and energy. By selecting the proper load size, you will reduce water waste. If you are unable to select a load size, run only full loads of laundry. Try to spread washing machine use throughout the week. Doing all household laundry in one day might seem like a time-saver; but it can harm your septic system, not allow your septic tank enough time to treat waste, and could flood your drainfield Clothes washers that bear the ENERGY STAR label use 35 percent less energy and 50 percent less water than standard models. Other Energy Star appliances provide significant energy and water savings.
