Manchester Water Works draws from Lake Massabesic, and the water is relatively soft. Older parts of the city have combined sewers, and the city has worked for years on projects to reduce overflows to the Merrimack River. Long, cold winters freeze pipes in unheated basements, porches and exterior walls, and many surrounding towns rely on private wells and septic systems.

Housing & construction
Triple-deckers and multi-family homes near the mills and downtown, single-family homes on the North End, and newer homes on the city’s edges.
