Keep your septic system in good working order
Have your septic system inspected by a professional at least every 3 years
Pump the septic tank when needed (about every 3 to 5 years)

Use proper cleaning practices
Dispose of mop bucket water down an inside drain, mop sink, or sanitary line. Do not pour mop water onto the parking lot or into a storm drain.
When appliances and vehicles must be washed, use proper contain and capture methods. Do not allow wash water to enter a storm drain. The dirt and soap can contaminate the natural water system
