History of OWASA

Before OWASA was established, three individual systems provided water and sewer services for southern Orange County. Each one was separately operated, independently owned and exclusively served the University of North Carolina at Chapel Hill, the Town of Carrboro and the Town of Chapel Hill. Cooperation between the whole Carrboro-Chapel Hill community and the State of North Carolina led to OWASA’s creation.


The 1970s brought rapid growth to the community. In November 1971, Governor Robert W. Scott appointed a Utilities Study Commission to assess the feasibility of retaining, selling or otherwise disposing of the water and sewer systems operated by the University. After nearly five years of analysis, the commission devised a best course of action: the transformation of the University’s water and sewer utility system and related properties into a public entity, serving both the school and the community.


In 1976, the governing bodies of the Town of Carrboro, the Town of Chapel Hill and Orange County determined to organize a water and sewer authority as the appropriate structure to acquire and operate the utilities. And so, OWASA was officially born when the University, the Town of Chapel Hill and the Town of Carrboro executed the Agreements of Sale and Purchase of the three separate water and sewer systems that year.


We took our first steps to bettering the community’s water infrastructure when we commenced operations on February 16, 1977.


Decades after its birth, OWASA still provides high-quality drinking water, wastewater and reclaimed water service to the entire Carrboro-Chapel Hill community.
