Committing a little attention to the care of your system is the best way to avoid the nightmare of a failing system. Do Conserve water to reduce the amount of wastewater that must be treated and disposed and to avoid overloading the system. Repair any leaking faucets and toilets. Only discharge biodegradable wastes into system. Divert downspouts and other surface water away from your drainfield.
Excessive water keeps the soil in the drainfield from properly treating the wastewater.
Keep your septic tank cover accessible for tank inspections and pumping. Install childproof risers and covers if necessary. Have your septic tank pumped regularly and inspected annually for leaks and cracks. Call a professional when you have problems or if there are any signs of system failure. Keep a detailed record of repairs, pumpings, inspections, permits issued and other maintenance activities.
