Water Resources

A major part of Rii’s business since the beginning has been working with different municipalities to provide civil engineering design. Our focus includes wastewater, stormwater collection systems, retention/detention basins, CSO regulator modifications, and small and large diameter sewer improvements ranging in size up to 108 inches to improve and sustain communities. We maintain high technical and management standards and our Municipal Engineering Division possesses the NASSCO PACP and MACP certified engineers that allow Rii to succeed on water resources projects. Repeat clients include the City of Columbus, Department of Public Utilities; Metropolitan Sewer District of Greater Cincinnati; Northeast Ohio Regional Sewer District and SD1 of Kentucky.
