To better control and prevent petroleum, oil, grease, sand, and other solids from entering the collection system, facilities may need to install a sand/oil interceptor (SOI) before discharge into the sanitary sewer. Automobile maintenance and repair shops, car washes, commercial parking garages, stone cutters and other businesses can potentially introduce these contaminants into the sanitary sewer. Before building construction or remodeling, construction drawings, including plumbing and details of the sand/oil interceptor, shall be submitted to their appropriate sanitation district agency. Your sanitation district can be found here by typing in your address.
Plans submitted to either the City of Littleton or the City of Englewood will be reviewed by South Platte Renew for compliance with the Petroleum Oil, Grease, and Sand Policy¹. The appropriate sanitation district agency will review plans submitted to other cities or counties for compliance with their rules and regulations.
Best management practices to manage petroleum oil, grease, and sand include installing drain screens, storing and managing chemicals and chemical waste properly, and sweeping or dry wiping floors before washing down. Employees must be trained to employ these best practices. Once trained, every employee should complete an Employee Training Form (you may download our forms for your convenience in either English² or Spanish³) and sink signs should be hung as reminders. Along with best practices to manage your wastewater, remember to use a state-certified waste hauler to pump and maintain your sand/oil interceptor properly.
