Wastewater Treatment Lagoons – City of Perry
Shiawassee County Michigan
LAN was retained by the City of Perry to design improvements for the rehabilitation of wastewater treatment lagoons 1 and 2, each with an approximate area of 13 acres, at the City of Perry Wastewater Treatment Plant. The project was funded through a grant and low interest loan from the Michigan Department of Environmental Quality (MDEQ) State Revolving Fund. Improvements included pond sludge removal and disposal; required excavation and backfill; installation of a new lagoon composite liner system consisting of geosynthetic clay liner (GCL), PVC geomembrane liner, and protective clay earth cover; riprap bank erosion protection; piping improvements; and site restoration.
