Sand Filter Septic System: Pros and Cons Sand Filter Septic System: Pros and Cons
The sand filter septic system is used for pre-treatment of effluent coming for your septic tank. A typical sand filter uses two tanks; the first tank is where the effluents in the wastewater are allowed to settle while the second tank receives the water from the first tank and pumps it into the sand mound for filtration.
As an alternative filtration system the sand filter septic system is ideal for areas which do not have enough soil to naturally filter out wastewater. Rocky areas and those which do not have access to conventional wastewater treatment facilities can use this type of system to protect the ground water from contamination. Since this type of system uses natural filtration methods it does not require intensive use of energy to clean wastewater.
Most types of sand filter septic systems use small to medium size pipes to transport the wastewater with effluents to the filtration tank. The suspended effluents in the wastewater can get stuck on the pipes preventing efficient water flow. Pipe clogging can cause overflows, backflows and may even shutdown your system.
Water overload is another threat to your sand filter system. If your sand filter system is built to meet the needs of your family alone, leaking pipes and faucets in the house can cause a minor disaster to your system. If your sand filter get more wastewater than it can handle, the tanks can overflow and you'll have to deal with smelly, dirty water.
