Why does a septic tank need to be pumped? Doesn the bacterial action take care of the waste?
In Alaska, tanks need to be pumped more often than in warmer climates since they are generally buried deeper. Since bacterial action works best in above 60 degree temperatures, and the temperature here averages about 47 degrees, solids accumulate faster and decrease the ability of the system to move the water into the leachfield at an acceptable rate. Additionally, we are using chemicals and chlorine in greater amounts than even 20 years ago which destroys the natural bacterial action in the tank. Periodic and proper pumping will remove this accumulation allowing the septic to perform effectively. TOP How does a septic system work? Septic systems typically have two major components: a septic tank and subsurface disposal field (also known as a leachfield or drainfield). The tank is a watertight receptacle designed to receive domestic wastes. The lighter solids called scum (mainly grease) floats to the top. The heavy solids settle to the bottom where bacterial action partially converts t
