Water and Wastewater Systems serves as the liaison to the local provider of public water and sewer services, Orange Water and Sewer Authority (OWASA), and provides the engineering management of the University’s water supply and wastewater collection systems for the use and conservation of water.

UNC-Chapel Hill has an active sustainability program that addresses long term water conservation, called the Three Zeros Environmental Initiative.

In 2004, UNC-Chapel Hill and OWASA started the development of a water reclamation and reuse system, which was completed in 2009. This system makes highly treated or reclaimed water available for appropriate non-drinking water needs, supporting water needs at Carolina’s chilled water facility and irrigation across campus.

UNC-Chapel Hill operates its own storm water system under the EPA’s National Pollutant Discharge Elimination System (NPDES) Phase II Program. This system is comprised of thousands of catch basins and inlets, miles of piping, dozens of structural best management practices (BMPs), and outfalls that discharge storm water into nearby creeks.

Energy Services Stormwater Systems is responsible for the oversight and management of the UNC-Chapel Hill stormwater system infrastructure and master planning.
