PWWD Well 4 Nitrate Treatment Facility

Port Washington Water District’s ion exchange system for nitrate removal at Well 4 was designed to meet the existing supply well capacity of 1,200 GPM and has the ability to expand should future increases in nitrate concentration occur. The full-scale system includes the ion exchange vessels, brine saturator, waste recycling and waste disposal systems, and minimizes waste production by partially recycling some of the wastewater for use in subsequent regeneration cycles. Located within a residential neighborhood, the structure that houses the system incorporates prevalent aesthetic elements found within the local community to minimize its visual impact and maintain consistency with the neighborhood.
