Wastewater/Sanitary Sewer System Design


GRA has years of experience in the planning, analysis and design of sanitary sewer systems. In this discipline, GRA has done extensive work in the City of Warwick, RI, through the Warwick Sewer Authority (WSA), for which GRA has conducted projects for many years.

GRA's assignments have ranged from the master-planning level of analysis to final design and the preparation of plans, specifications and estimates for bidding. In addition to design services, GRA also provides full-time resident inspection and office support on all of our WSA design projects.
