Filtration system a fit for tight space

Problem: A two-bedroom home in Huron County, Michigan, had limited space for an onsite septic system due to a small lot and a looping driveway that took up most of the yard. Additionally, the repair site had heavy clay soils and a shallow seasonal high water table 12 inches from grade.

Solution: Milan Supply worked with the county health department to come up with a solution for the tough site. The Eljen GSF, or Geotextile Sand Filter, system was specified due to the lack of space. The raised mound is smaller than a conventional system and was installed by Greg Wares. Milan Supply provided on-site training. Then 20 B43 modules were installed in two 40-foot-long laterals. Effluent is pumped to a distribution box, where it is distributed to the modules through 4-inch perforated pipes.

Result: The homeowner has a passive treatment system that fits the limited space. The raised system took up less space than a conventional mound, which saved material costs. 800-444-1359; www.eljen.com.
