What We're Doing

The Central Zone and 44th Avenue Water Towers are part of the Water 2040 Program. Central Zone Tower will be located next to the existing OSU water tower on McElroy Road. This tower will supply water to the future West Highway 51 Booster Pump Station located near Ortho Oklahoma for serving customers connected to Range Tower at 19th Avenue and Range Road, known as the Southwest Distribution Zone. This location also allows Central Tower to connect to the City's existing Central Zone to improve system operation into town. 

44th Tower will replace the two Twin Tower standpipes located north of 44th Avenue between Country Club and Range Roads. The service area for these standpipes are currently under a moratorium on new water taps in order to maintain regulated pressure to existing customers. The new 44th Tower will improve pressure to the City's rural distribution system to include Kenslow Farms, Nottingham, Woodlakes I and II, and Briar Creek Developments.

Anticipated Milestones
