                                                             wastewater facilities

                                                             The City of Colleyville purchases treated water
                                                             from the Trinity  River Authority.  Water
                                                             Distribution then manages this vital resource
                                                             around the clock by maintaining three elevated
                                                             storage towers, one  ground storage tank, a
                                                             pump station, and 200+ miles of water mains.
                                                             Routine maintenance of  these assets includes
                                                             flushing dead-end  water mains, regularly
                       replacing meters, and exercising valves throughout the network. Water is routinely
                       sampled from various sites throughout the city and tested for chlorine residual and
                       bacteria. Samples are also tested for lead and copper. The  Engineering Division
                       oversees the construction of water infrastructure delivery system components to make
                       certain that improvements meet Colleyville Development Standards. These standard
                       practices ensure the delivery of clean, pure water to citizens.

                   6.  Ensure  wastewater is  managed in a safe and efficient manner for the sake of
                       maintaining the public health.

                       3.2 - Ensure regular replacement of water and wastewater facilities

                       Wastewater collection provides environmentally-friendly conveyance of our
                       wastewater to the treatment plant operated by the Trinity River Authority.  Maintaining
                       and operating existing infrastructure to reduce the effect of our  waste material on
                       health and the environment is crucial. The Wastewater division takes an aggressive
                       approach  to this responsibility through a proactive monitoring and  preventive
                       maintenance program. These operations include cleaning and inspecting 180 miles of
                       sewer mains in addition to 2,686 manholes and
                       three (3) lift stations.  The construction of new
                       public infrastructure is inspected by  the
                       Engineering Division to ensure that it meets all
                       necessary specifications. This  comprehensive
                       program serves the public by maintaining a safe
                       and healthy environment.
