Westchester Joint Water Works (WJWW) is a nonprofit public benefit corporation formed in 1927 with a duty to act in the best interests of the public it serves in providing a reliable source of safe drinking water.
WJWW is composed of three member municipalities: the Village of Mamaroneck, the Town of Mamaroneck, and the Town/Village of Harrison, which formed WJWW for the purpose of operating a combined municipal water works system.
