Septic System Don'ts

1. Limit garbage disposal use. A garbage disposal adds solids and grease to your system, which could lead to drainfield failure.
   
   
2. Don't use septic tank additives or "miracle" system cleaners. Some of these chemicals can actually harm your on-site sewage system by allowing solids to flow into and clog the drainfield. The chemicals can also contaminate ground and surface water.
   
   
3. Don't dispose of water from hot tubs into the on-site sewage system. Large volumes of water are harmful to the system, and the chlorine can destroy important bacteria in the system. Drain hot tubs onto the ground, away from the drainfield and not into a storm drain.
   
   
4. Don't flush solid wastes into the septic system. These include diapers, cigarette butts, coffee grounds, tampons, condoms and grease.
   
   
5. Don't put strong chemicals, such as cleaning products, down the drain. Household chemicals, such as drain cleaners, paint thinners and floor cleaners, can destroy important bacteria in your septic tank and contaminate ground and surface water.
   
   
6. Don't construct patios, carports or use landscaping plastic over the drainfield. Grass is the best cover for your septic tank and drainfield. Soil compaction and paving prevents oxygen from getting into the soil. This oxygen is needed by bacteria to break down and treat sewage.
