Septic System installation is a major expense for anyone building a new home. Consider a consultation with a contractor for Septic Services in Mcdonough GA. Indeed, a lot of work is done before a system is purchased and installed. Initially, the contractor is required to do a perc test. The test measure how fast the soil drains, which is key to most septic systems.
Conventional Septic System
A septic system based on gravity is the most common. A pipe drains water and waste from home into a septic tank. The tank contains bacteria that help to break down solid waste. Finally, wastewater leaves the tank and flows into the drain field. The drain field contains bacteria in the soil that treats wastewater again. To function properly, the drain field must have a depth of three feet. The average cost of this system is $7500-$10,000.
Septic Services in Mcdonough GA may recommend a pressure distribution system if the soil is less than three feet. This system uses a conventional septic tank and drain field. However, a pump must be used to direct wastewater from the tank. The pump spreads effluent over a wider area, so it absorbs faster. This system generally runs between $9,000-$13,000.
Working Around Soil Depth
Advanced systems must be installed if the soil is not deep enough. The systems cost between $13,000-$20,000. For example, the sand filter system consists of a large underground box full of sand and rocks. A system of pressurized pipes forces effluent out to cover the sand. Sand cleans the effluent, which is later pumped to the drain field. A second treatment takes place, and the water drains into the ground.
Sand Mounds
Sand mounds are used in many areas to treat waste. A mound is built above the ground in areas with really shallow soil. Pressurized pipes send effluent into the mound where it drains through the sand. Mound systems can run as high as $20,000. Finally, aerobic systems are popular because they do not require as large a drainfield as other systems. This system uses oxygen to break down solid waste. Unfortunately, aerobic systems cost three times as much as a gravity system. For more information, contact MTG Services.
