Oldcastle Precast offers a variety of products designed to reduce harmful pollutants in storm water runoff to the nation's valuable surface waters.

  Grease Interceptors & Traps

Grease interceptors are effective in grease removal, along with decreasing maintenance costs and deterioration of collection systems. These interceptors protect septic systems and sewage lines from plugging and failing. Septic and holding tanks are available for industrial and commercial uses in capacities of 500 gallons or larger. Custom configurations are also available.

  Oil / Water Separators

Our oil/water separators intercept grease and oil in storm water runoff and are available in a wide range of sizes and styles and are easily installed aboveground and underground. The separators use enhanced coalescing and gravitational separation to improve the separation process and reduce the frequency of maintenance and cleaning.
