Why is the Sewer Capacity Certification (Allocation Letter) necessary?
Any construction or change of use that will cause an increase in wastewater discharge to a sewer will need a certification letter. This includes such things as changing a single-family house to a duplex, adding extra seats to a restaurant, adding a new doctor to a practice, or building a new house. If you are unsure, call DERM’s Wastewater Section at 305-372-6899.
