At the heart of the MCWA's operations is its commitment to ensuring the water it delivers meets or exceeds all federal and state drinking water standards.

Water Supply and Treatment Process

The MCWA’s water supply is primarily sourced from Hemlock Lake and Canadice Lake, two of the Finger Lakes in New York. The authority operates two water treatment plants, the Hemlock Filtration Plant and the Canadice Filtration Plant, which have a combined capacity to treat up to 40 million gallons of water per day. The treatment process involves the use of advanced technologies, including ozonation and ultraviolet (UV) light disinfection, to remove bacteria, viruses, and other microorganisms from the water.
Water Distribution and Infrastructure
Once treated, the water is distributed to customers through a network of over 1,200 miles of water mains, ranging in size from 4 to 36 inches in diameter. The MCWA is also responsible for maintaining and upgrading its infrastructure, including the replacement of aging pipes and the installation of new valves and hydrants. In 2020, the authority invested over $10 million in capital improvements, including the replacement of over 10 miles of water main and the installation of over 500 new valves and hydrants.
