Project Overview

Generally, most new construction projects occur on undeveloped parcels of land in which roadways are constructed. This requires the installation of new water main, fire hydrants and service lines. It also may necessitate backflow prevention devices (RPZ) for compliance with Suffolk County Health Department regulations.

Sometimes, the project may be located on a public road where the Authority has existing water supply. In this case, water service will consist of the domestic service line, backflow protection and possibly fire sprinkler service.

For water main extensions, the developer/builder must enter into a contract with the Authority to have the main, fire hydrants and other appurtenances installed. Detailed site plans, easement information, fire hydrant locations and service line locations must be supplied to the New Service Department for review.

A site plan is required, which includes tax map numbers and tie-ins to the nearest cross streets. In addition, easement descriptions for all roadways, flow demand, drainage plans and backflow design plans are required. For water main extensions, a contract and hydrant agreement must be executed. Contract packages, which include easement information, hydrant locations and other requirements, must be returned complete with the execution of the contract. Incomplete packages will not be accepted.
