Water improvements plan puts focus on west Oklahoma City

The city also expects to begin engineering and construction on a second Atoka Pipeline over the next five years. The second pipeline would increase the supply of the city's raw water from southeastern Oklahoma to meet expected increased demand.

That project is subject to the outcome of ongoing litigation over water rights in the southeastern part of the state. The Choctaw and Chickasaw nations are disputing water rights held by the city and state in the area.

The water plan also commits the city to rehabilitating wastewater drainage mains in neighborhoods and building more capacity for stormwater drainage.
