Manchester Water Works Water Quality Reports

In June 2020, Salem began receiving water as a member community of the Southern NH Interconnection Project or Regional Water Project. The originator of this water is Manchester Water Works (MWW) who uses Lake Massabesic as its source. Since 1874, Lake Massabesic has served as the water supply for Manchester and portions of six surrounding communities. In order to satisfy stringent state and federal drinking water regulations, the lake water is purified at Manchester's Water Treatment Plant. This facility was completed in 1974 and has since been routinely updated with state-of-the-art equipment to improve quality control and operational efficiency, and was significantly upgraded in 2003-2006. Located adjacent to Lake Massabesic, the plant treats all of the city's water before it is pumped into a 500-mile piping network for distribution to homes and industries. In the near future (approximately 2023), water from the Merrimack River will provide a much needed additional supply for our customers. Construction will begin on a new water treatment facility located in Hooksett, NH, in 2021, to produce water that meets or exceeds the high level of quality leaving the Lake Massabesic plant. The Water Quality Reports are attached.
