The mound system looks a lot like it sounds. It is a system that includes a septic tank, a dosing chamber, and a large mound of sand and gravel. The wastewater is sent from the septic tank to a second tank called a pump tank or dosing tank. In the dosing tank, the wastewater is evenly distributed in doses into the mound. Wastewater is then partially treated as it moves through the mound sand. Final treatment and disposal occurs in the soil underneath the mound.
Depending on local prices of sand, gravel, and trucking, a mound may be more or less expensive than other alternative systems. If a mound is the best option for your site, we can help you design and install a mound with superior, longer lasting components.
