Problem: A three-bedroom home was being built on a tight lot in Norwalk, Ohio. The property has a perched seasonal high water table at 20 inches below grade, and the homeowner wanted the system to be in the front yard to preserve backyard space. The system would also need a nonstandard configuration to meet multiple setback requirements. 

Solution: A shallow L-shaped mound was designed to meet the setbacks from the road, driveway and property line. A pump to a gravity Eljen GSF system was chosen to allow for a 1-foot depth credit to the seasonal high water table. Flenner Water Well and Excavating installed the mound system, which included 27 A42 GSF modules as well as a dual-chamber 1,500-gallon septic tank and a 500-gallon pump chamber from Spoerr Precast. The mound’s bed area has one row of A42 modules, and measures 4 feet wide by 108 feet long, with an overall basal area of 16 feet wide by 121 feet long. 

Result: The depth credit reduced the amount of sand needed for the site, producing a shallower mound. Utilizing the front yard, the homeowner will preserve the backyard. 800-444-1359; www.eljen.com
