The Utility Division  supports the missions of the County and the Engineering Department with the operation and maintenance of the Triangle Wastewater Treatment Plant (TWWTP) and collection system.  The TWWTP serves the southeastern portion of Durham County inside and outside the City limits and the Research Triangle Park. The plant also serves a portion of the Town of Cary on an interim basis through calendar year 2013. The Division is dedicated to promoting environmentally sound wastewater development and assist residents with failed septic systems in connecting to public sewer. New development increases the tax base, while connection of failed septic systems improves the environment.
