Projects
Water Mains across Little Bay
This project consists of design and construction of 24-inch water transmission mains beneath Little Bay to replace existing mains. Investigations have identified degraded conditions of the existing water mains and valves. 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.

Collins Wellfield Improvement New Groundwater Well
This project resulted from new water supply source investigations. Test wells were drilled in areas around the existing Collins Well to determine the potential for enhancing productions from its associated aquifer. The capacity of the existing Collins Well has declined since it was installed and historical data indicates greater yield potential from this aquifer.
Status: Well-drilling and construction is ongoing
