Background:
The Water Distribution Storage Tank Mixing Improvements is a project funded by Oklahoma Water Resources Board Financial Assistance Program Loan No. FAP-17-0004-L.

After an extended period of monitoring the disinfectant quality at the ground storage facilities, Staff along with our consultant, PEC, PLLC, determined that mixing will greatly benefit the City's secondary disinfection. These improvements will improve the City's disinfectant quality in our ground storage tanks, which constitutes up to nine (9) millions gallons of water.
