Please note that a full updated list of registered maintenance providers can be obtained from your local Health Authority.




Minimize the use of bleach and cleaning solvents.
DO NOT discharge from water treatment devices including water softeners into system.
Garbage disposal unit is NOT to be used with septic systems. A garbarator will overload the septic tank, degrade wastewater treatment and decrease drain field life.

DO practice water conservation and endure that fixtures do not leak.

DO NOT use powdered laundry detergent or dish washer soap, liquid soap is acceptable.

No water softeners, floor drains, roof drains or perimeter drains to drain into wastewater system.

DO check toilets for leaks annually by placing dye in tank (food coloring) and leaving it for several hours. The dye should not appear in the toilet bowl.

DO NOT flush anything (e.g., Condoms, Q-tips) into system that does not pass through the human body with the only exception of toilet paper.

Irrigation over mound or drain field should be closely monitored. Excessive irrigation infiltrates into and hydraulically overloads system. Hydraulic overload will cause failure in system.
