Portsmouth Downtown Sewer and Water System
Victor Valenzuela, PE
This project involved the installation of 10,200 LF of 8-inch to 16-inch diameter gravity sewer, 9,530 LF of 8-inch to 16-inch diameter water main, and 920 LF of 12-inch diameter sanitary force main within a 70 acre portion of Downtown Portsmouth bounded by High Street to the north, Effingham Street to the west, South Street to the south, and Water Street to the east.
The land use in the project area is heavily developed with mostly commercial properties and City of Portsmouth buildings. In addition to being the designers for the project, Draper Aden Associates provided program management services during the design and construction phases of the project. As part of these services Draper Aden Associates provided detailed construction sequencing plans, construction phasing schedules, and alternative access options for property owners. We also assisted the City with public relations matters via public meetings, newsletters, property owner e-mails and content for a project specific website.
