Case Study: System minimizes maintenance for homeowner

A Homes For Our Troops build project in Washington state uses an Eljen GSF system to minimize future maintenance costs for the homeowner

Problem: Homes For Our Troops is an organization that builds specially adapted homes nationwide for severely injured veterans. One build project in Shelton, Washington, needed a treatment system, but the organization was looking for an option that would minimize future maintenance costs for the homeowner. The site had about 5 feet to the restrictive layer, loam soils and existing vegetation on the site. 

Solution: Fred Kegel, P.E., designed an Eljen GSF, or Geotextile Sand Filter, system. The drainfield consists of three trenches with 15 A42 GSF modules in each trench. Bob Paysse of Pioneer Digging installed the system, including a pump chamber and dual compartment tank. Effluent for this system is pressurized by sleeving a pressure lateral through a 4-inch perforated pipe on top of the A42 modules before being dispersed over the GSF modules and into the ASTM C33 sand base below. 

Result: The system was quickly installed, helping the build project to continue as planned so the veteran and his family could move into their new, accessible home. 800-444-1359;
