Provided a conceptual design for an on-site wastewater collection, treatment and disposal system for a 129-unit garden apartment complex for handicapped persons. The design called for a septic tank for each cluster of apartments with a variable grade effluent sewer (VGES) system to convey the septic tank effluent to a package treatment plant. The treatment plant was designed to achieve a high degree of nitrogen removal since nitrate concentrations in the groundwater were an issue in this location. A grinder pump station with a small diameter force main was used. Disposal was designed to include sub-surface drip irrigation and a conventional leach field. The estimated total cost of the system was approximately $750,000.
