A mobile home park in Michigan had a failed septic system resulting in surfacing effluent and contamination of a nearby lake. The site had an existing 20,000-gallon septic tank, and the owner was restricted to pumping and hauling the waste away. A replacement drainfield was not possible due to site constraints, including limited space, poor soil conditions and a high water table.
After careful consideration, a new system was designed to treat 5,000 gpd, utilizing the existing septic tank and a Clarus Environmental WW4 filter. Two ZFL-2400 Fusion treatment systems were installed in parallel with influent evenly split using a Tru-Flo splitter. Treated effluent was collected in a 1,500-gallon dose tank. Two Zoeller Model N153 pumps were used to dose the low-pressure drainfields.
Since startup, the system has performed perfectly. System maintenance is performed twice a year.
