About this file

This is an engineering exhibit document prepared by PARE Engineering for the University of Rhode Island, detailing the sanitary sewer system plan associated with the permanent PFAS water treatment facility project. The document provides technical specifications and design considerations for the sanitary sewer infrastructure that will support the new water treatment facility at URI. The exhibit serves as a supporting document for the design, build, and construct contract opportunity for the permanent PFAS water treatment facility, establishing the baseline requirements and system specifications necessary to accommodate wastewater from the facility's operations.

The sanitary sewer system plan outlines the engineering requirements, system capacity, connection points, and operational considerations for managing wastewater generated by the PFAS treatment facility. This technical exhibit functions as a binding reference document for bidders and contractors responding to the contract opportunity, ensuring that all proposed designs and construction methodologies align with the established sanitary sewer infrastructure parameters. The plan provides essential engineering data that contractors must incorporate into their comprehensive project proposals for the design and construction of the permanent water treatment facility at the University of Rhode Island.
