Ejector Basin Installation Detail

About this detail

A round fiberglass ejector basin is set upon a level and smooth base of either compacted base rock or concrete with six inches minimum thickness and twelve inches minimum beyond the perimeter. The basin features an anti-float ring and a field-installed waste inlet fitting, with a concrete ballast of two point zero yards minimum per basin six inches minimum width by six inches minimum thick. Inside the basin, a submersible pump connects to Schedule eighty PVC pumped waste piping running vertically. The discharge line transitions through a waste and storm water flanged ball check valve, an AWWA C-five fifteen flanged gate valve, and a series of lifting lugs welded to the basin wall. A five-inch structural slab is poured against the fiberglass basin, set atop twelve inches of crushed rock, compacted grade, and pea gravel or control density fill six inches minimum wide around the basin. Ejector basin installation and backfill instructions outline requirements for inspection, excavation, backfill material, ballasting, temporary plywood covers, stainless steel fastening hardware, and electrical conduit sleeves.
