Most septic system failures are due to heavy Biochemical Oxygen Demand (BOD) discharge into the soil

In using the Whitewater Treatment Unit you can be proud that you are directly contributing to a cleaner, safer environment.

Whitewater works by using the bacteria nature provides. As a result of air being pumped into the system, bacteria thrive and grow in much greater numbers than would occur naturally. This "overpopulation" of bacteria speeds the process of breaking down the sewage, making it safe for release into the environment.

The process occurs entirely within the self-contained Whitewater Treatment Unit which is comprised of an outer mixing tank and a cone-shaped settling chamber. Raw, unsettled domestic wastewater enters directly into the mixing tank where mixing occurs through an air distribution system. Solids remain in suspension with a general flow up the outer plant wall and down the outside of the settling chamber.

The mixed liquid then enters the settling chamber from the bottom. The settling chamber maintains a quiet condition which allows solids to settle down and re-enter the mixing chamber for more processing. The liquid is hydraulically displaced upward and is discharged as clear, odorless treated water, which meets or exceeds approved water quality standards.

The liquid then flows through an inline filter to an optional (depending on conditions) single pass free access sand filter which allows further treatment and protection from hydraulic overloading prior to entering the disposal system. The liquid is then collected and pumped into a pressurized shallow buried trench system or a dosed gravity flow leaching bed. Use of the shallow buried trench allows disposal in very limited space and/or heavier soil conditions.
