After the installation of a septic system, most homeowners tend to forget about it; out of sight, out of mind. But the household septic system performs a vital task and requires a little care and maintenance to keep it functioning properly.
Certain chemicals can harm the delicate balance in a septic tank and should not be run through the system. They include:
- Paints and solvents
- Thinners
- Nail polish remover
- Drain cleaners
- Motor oil
- Kerosene and gasoline
- Floor wax
- Chlorine bleach
Other materials may not harm the system chemically, but could cause a blockage. These items cannot be digested by the microorganisms in the septic tank. They include:
- Grease and cooking oil
- Animal fat
- Coffee grounds
- Plastics
- Cigarettes
- Cotton balls and cotton swabs
- Condoms
- Feminine hygiene products
- Diapers
Another essential part of maintaining your septic system is having the septic tank pumped on a regular basis. Solids will accumulate in the septic tank and must be removed regularly before they migrate into the leachfield and clog the pipes. The Health Department recommends having septic tanks pumped every 3 - 5 years. Click here for a list of registered haulers.
Some additional tips on protecting your sewage treatment system:
Do not build anything over or within ten feet of any part of your septic system. This includes driveways, fences, swimming pools, sheds, decks and house additions.
Do not allow anyone to drive heavy vehicles over any portion of the sewage system. Pipes and tanks may be damaged or crushed and the soil may become compacted, which could minimize its ability to filter and absorb sewage.
Do not plant any trees or shrubs with complex root systems, like willows or soft maples, near any portion of the system. Their roots will travel laterally underground as they seek water and will grow into pipes causing blockages.
