One of the most important measures you can take to prolong system life is to conserve water. The more water you use, the more water must be treated and disposed of. Be sure to repair all leaky fixtures. Reduce the amount of water used in laundering, dish washing, bathing and toilet use by utilizing water conserving fixtures. Be especially stingy at times of the year when heavy rains or melting snow saturate the ground, reducing the private sewage system's ability to treat wastewater adequately.
Many people choose to wash clothes only once a week.
While this may be convenient, it is not good for the disposal system. Up to 60 gallons per cycle can be discharged by an automatic washer. If several loads are done in one day, it can put considerable stress on the system. A better practice is to spread it out through the week, washing no more than two loads a day. Try to wash only full loads.
