A New Water Reuse Project

Suez North America operates and manages Nassau County’s wastewater system, which is – according to the information – the largest public-private partnership for water and wastewater services in the United States of America.

The project, completed in July 2019, cost approximately 1.1 million US-Dollar, paid entirely by Suez. By reusing treated plant effluent, the Cedar Creek plant will preserve up to 300 million gallons of groundwater each year, the information says. The plant has traditionally used about 600 gallons of groundwater per minute for non-potable uses, such as process cooling water and washing down equipment and tanks. The water reuse system takes water from the screened plant effluent system and treats it for solids removal and high-level, multiple-barrier disinfection using chlorination and ultraviolet (UV) disinfection.
