Care for a Septic system
Practice water conservation. The more wastewater you produce, the more the soil must be treated and disposed of. By reducing and balancing your water use, you can extend the life of the drainfield, decrease the possibility of system failure, and avoid costly repairs.
Keep accurate records. Know where your septic tank system is and keep a diagram of its location. Records of its size and location may be available at your local health agency. It is also wise to keep a record of maintenance on the system. These records will be helpful if problems occur, and will be valuable to the next owner of your home.
Inspect your system once each year. Check the sludge and scum levels inside your septic tank to assure that the layers of solids are not within the early warning levels. Also check the tank to see if the baffles and tees are in good condition. Periodically inspect the drainfield and downslope areas for odors, wet spots, or surfacing sewage. If your drainfield has inspection pipes, check them to see if there is a liquid level continually over 6 inches. This may be an early indication of a problem.
Pump out your septic tank when needed. Don’t wait until you have a problem. Routine pumping can prevent failures, such as clogging of the drainfield and sewage back-up into the home. Using a garbage disposal will increase the amount of solids entering the septic tank, requiring more frequent pumping.
Never flush harmful materials into the septic tank. Grease, cooking fats, newspapers, paper towels, rags, coffee grounds, sanitary napkins, and cigarettes cannot easily decompose in the tank. Chemicals such as solvents, oils, paint, and pesticides are harmful to the system’s proper operation and may pollute the groundwater.
Keep all runoff away from your system. Water from surfaces such as roofs, driveways, or patios should be diverted away from the septic tank and drainfield area.
Protect your system from damage. Keep traffic, such as vehicles, heavy equipment, or livestock off your drainfield or replacement area. The pressure can compact the soil or damage pipes. Before you plant a garden, construct a building, or install a pool, check on the location of your system and replacement area.
Landscape your system properly. Don’t place impermeable materials over your drainfield or replacement area. Materials, such as concrete or plastic, reduce evaporation and the supply of oxygen to the soil for proper effluent treatment. They can also hinder access to the system for pumping, inspection, or repair. Grass is the best cover for your system.
Never enter any septic tank. Poisonous gases or the lack of oxygen can be fatal. Any work on the tank must be done from outside.
