Let' face it, nobody wants to have to deal with a septic tank issue. By following these simple steps you will have a septic tank that will require very little maintenance in the years to come:

Do not flush anything down the toilet other than: toilet paper, and human waste. Period. Your septic tank has it's own natural bacteria within the tank that will break down solids and turn it into sludge naturally. No additives are necessary. When doing laundry, liquid soap is better that powder for septics.

If you are a cabin owner with an outhouse, do not put "Lyme" or anything in the "hole" other than what it intended use is for. Any additive will turn rock hard making it impossible to pump out. To keep odor down, just add alot of  good old water.

Have your septic pumped routinely (we recommend once every 2-3 years)  to maintain the proper balance and flow to keep your system running smoothly and efficiently. ( We do this for you by keeping track of when your tank was last pumped and send a reminder when it is due) 

Consider installing a riser to replace the opening cover of your tank. This makes for easy access for the pumper and avoids having to "dig" to locate the access.The easiest and best way to get a tank good and clean is have the cover exposed.

Periodic cleaning of the effluent filter (if installed) is vital in the life of a septic tank. A simple spray with a garden hose to keep this filter clean, can have a huge impact of avoiding issues with the tank.

Here are a few things to NEVER allow to go into a septic tank:( These items do not break down and this runs the risk of slow, gurgling drains and odor. This could potentially be an expensive fix. FACT: There are no moving parts to a septic tank.

 A shallow, covered excavation made in unsaturated soil containing rock or gravel into which effluent is discharged through distribution piping. The soil under and around the drain field accepts, treats and disperses effluent as it percolates through the soil, ultimately discharging to groundwater.

A small subsurface structure which receives septic tank effluent and distributes it to all segments of the soil system components.

Sewage water or other liquid partially or completely treated or in it's natural state flowing out of a septic tank or system component.

A removable, cleanable devise inserted into the outlet piping of the septic tank designated to trap excessive solids that would otherwise be transported to the drain field.

A buried, watertight tank, usually made of concrete, designed to receive and provide primary treatment of raw wastewater. There is an inlet baffle, an outlet baffle, or tee on the pipes inside the tank. These work to keep the scum and sludge inside the tank.

This the very top layer of a septic tank. Floatable solids such as grease and feces that combine on the top of the liquid in the tank is known as the scum layer. This is what you see when looking into a tank.

The heavy, slimy deposit found at the bottom of the septic tank.

This is considered the middle layer of a septic tank, This is the stuff that does not float or sink. It just hangs out in the middle of the tank.
