CIP EF-18-WD-90: NEW GROUNDWATER SOURCE

Description: This project consists of constructing, permitting and connecting a new groundwater supply well into the Portsmouth water system. This project is important to ensure long-term sustainability of the water supply.

CIP EF-20-WD-92: WATER STORAGE TANKS PAINTING

Description: The City owns and operates 4 water storage tanks. These facilities are inspected routinely for the condition of the interior and exterior finishes. These funds cover the costs to repaint these tanks when needed. FY21 funds will cover the exterior painting of the Newington Booster tank. This work will be significant because the existing paint and primer contain lead. FY23 funds will be used to repaint the exterior of the Spinney Road tank.

CIP EF-18-WD-91: WATER TRANSMISSION MAIN REPLACEMENT

Description: This project consists of design and construction of water transmission mains beneath Little Bay to replace existing mains, which are over 60 years old. Preliminary investigations of the existing water mains and valves have identified degraded conditions. Due to the importance of this water main, this project is necessary to ensure water is continuously supplied from Madbury to Portsmouth and service is not disrupted. FY21 funds will be used for permitting and design, and FY22 funds will be used for construction.

CIP EF-13-SD-97: MECHANIC STREET PUMPING STATION UPGRADE

Description: This pumping station project will include a comprehensive upgrade to the City’s largest pumping station to improve its operation and efficiency. The City purchased the adjacent property and will work on a site master plan for the area from the pump station to Peirce Island Road. The site master plan will be a public process. It will address the park, pump station and access to the water in this area. The new pump station will take into consideration the site use and improve the station’s overall aesthetics to reduce impact to the neighborhood and sea level rise. FY23 funds will be used for conceptual design of the pump station.
