Eljen GSF System Follows Curved Driveway Setback
The Eljen GSF's design flexibility allows homeowners to switch from costly pump and haul to a code compliant septic system.

Problem: The owners of a three-bedroom lake home in Wisconsin utilized a holding tank and wanted to have a drainfield installed. The wooded property had limited space for a septic system due to multiple setbacks, including a well located at the side of the house, an S-curved driveway and the lake behind the house.
Solution: H&H Construction designed and installed a pump-to-gravity system that navigated through the wooded area. The installation included adding a 660-gallon pump chamber in series following the existing 1,000-gallon septic tank, with effluent pumped to the drainfield. A 77-by-6-foot trench was constructed to follow the setback from the curved driveway. The drainfield consists of a base of ASTM C33 sand and 14 Eljen GSF (Geotextile Sand Filter) B43 modules. The pipe on top of the GSF modules was connected using elbow fittings.
Result: The homeowners were able to stop costly pump-and-haul services by having a code-compliant drainfield. The Eljen GSF system ensures effluent is treated to secondary treatment standards before reaching the groundwater and lake.
