Body
BACKGROUND: On May 22, 2012, the Norman Utilities Authority (NUA) approved Contract K-1112-124 with Carollo Engineers, Inc. to perform final design services for the Phase II Water Treatment Plant (WTP) Improvements. An 8-month pilot project was performed as a part of that contract to determine the final design parameters and arrangement of the treatment system. Three process alternatives were studied and it was concluded that ozone should be used to address taste and odor concerns and pharmaceutical/algal toxin reduction while a system employing Ultraviolet Light would function as the primary disinfectant.
On January 13, 2015, Norman citizens approved a water rate increase with 67% voting in favor of the increase. The rate increase was expected to generate capital of approximately $49 million of which $31 million was to be used for the WTP Phase II Upgrade.
On February 2, 2015, the NUA approved Amendment No. 1 to complete the design, provide construction administration services, and provide full-time on-site construction observation services for the WTP Phase II Upgrade. The design was completed and plans and specifications were submitted to the Oklahoma Department of Environmental Quality (ODEQ) on October 4, 2016. The ODEQ approved the plans and specifications on January 18, 2017. The Phase II WTP improvements include:

* New maintenance building;
