In a typical household, most of the water used indoors is used in the bathroom, and there are several little things that can be done to conserve water there. For example, try to avoid letting water run while washing hands and brushing teeth. Avoid taking long showers and install water saving features in faucets and showerheads. These devices can reduce water use by up to 50 percent. Low-flush toilets use 1.6 gallons per flush compared to the three to five gallons used by conventional toilets. It is also important to avoid overtaxing your system by using a lot of water in a short time period, or by allowing too much outside water to reach the drainfield. Try to space out activities requiring heavy water use over several days. Also, divert roof drains, surface water, and sump pumps away from the drainfield.
