The Primrose School of Strongsville is a premium early education and care school that serves infants through Pre-K and offers before- and after-school care services. The school includes a 12,000 square-foot school building and a 10,000 square-foot playground.

Engineers from NEFF and Associates needed to design a stormwater management system that could meet the Ohio EPA stormwater permit. The site did not have space for above-ground stormwater storage. Even if space was available, having an above-ground pond was undesirable due to safety concerns, so the engineers turned to an underground solution.

The system consists of two Cascade Separators and a corrugated metal pipe (CMP) underground detention system. The Cascade Separator is the latest innovation in hydrodynamic separation from Contech that uses advanced sediment capture technology to provide the highest sediment removal efficiency of any Contech HDS product. One of the Cascade systems installed included a grate inlet, which eliminated the need for a separate inlet structure. The underground detention system is made from 549’ of 72” diameter CMP providing 15,523 of storage. Using 72” CMP maximized storage volume on the tight site.

A Contech Stormwater Engineer provided the engineer with storage calculations and contract drawings, while a Contech Sales Engineer provided the contractor with on-sight installation support. The result was another successful installation.
