<br />Policy.
<br />The Town of Hillsborough, like most water and sewer utilities, continues to experience sewer blockages
<br />caused by the accumulation of fats, oils, and grease on the surfaces of sewer lines. Greasy wastewater
<br />can be discharged to the sewer system from several sources, including food service operations. In order
<br />to reduce sewer blockages, customers in the Hillsborough service area that discharge wastewater that
<br />contains grease must install and properly operate and maintain a grease trap or interceptor.
<br />Grease, oil and sand interceptors shall be provided when, in the opinion of the Town of Hillsborough,
<br />they are necessary for the proper handling of wastewater containing excessive amounts of grease and
<br />oil, or sand; except that such interceptors shall not normally be required for residential users. All
<br />interception units shall be of type and capacity which is certified by a qualified professional, such as an
<br />engineer, as meeting Hillsborough's requirements and shall be easily accessible for deaning, testing
<br />and inspection.
