Grease Traps must be cleaned weekly unless less cleaning (frequency) may be determined upon inspection with Town staff. Interceptors must be cleaned twice a year, unless less cleaning may be determined by Town staff, when grease and solids reach 25% of the interceptor’s capacity. Records must be kept by the restaurant to show that regular inspections and cleaning were done. When pump out is required, you must select a company to completely empty the interceptor/grease trap and properly dispose of the material. Public Works Sewer staff inspects every grease trap and interceptor every year to make sure adequate cleaning is taking place. During the inspection, staff will be using this form to complete the inspection.
