Applications & Permits
If you are developing a new property, the building permit process requires you to obtain clearance from the Board of Water Supply for a water meter. The BWS also reviews all construction plans of private, City, State, and Federal projects that may influence and/or impact BWS facilities. Here are common forms needed for various types of development.
