CONSIDERATION OF APPROVAL, REJECTION, AMENDMENT, AND/OR POSTPONEMENT OF CONTRACT K-2021-117 BY AND BETWEEN THE NORMAN UTILITIES AUTHORITY AND FREESE AND NICHOLS, INC. IN THE AMOUNT OF $47,850 TO PROVIDE ENGINEERING SERVICES FOR THE BLENDING OF WELL 5, 6, AND 52 AT THE WATER TREATMENT PLANT AND BUDGET TRANSFER BETWEEN PROJECT ACCOUNTS AS OUTLINED IN THE STAFF REPORT.
Body
BACKGROUND: Each groundwater well utilized by the City of Norman is required to be analyzed for multiple parameters each month before entering the distribution system. In order to mitigate time and money used for collecting and analyzing tests, the City has started to combine multiple wells before entering the distribution system. Combining wells allows for increased water supply, as well as lowering cost associated with sampling each well and the time needed for personnel to collect multiple samples each month from every well. The City currently has two locations that serve as blending points for other wells in the system. Based on their proximity, this project will combine ground water from Wells 5, 6, and 52 at the Water Treatment Plant (WTP) before entering the distribution system.
The location for this blending point would be on the west side of the Water Treatment Plant (WTP) on Robinson Street where Well 6 is already connected. Water from Wells 5 and 52 would be combined at the intersection of Robinson Street and 36th Ave NE before combining with Well 6 at the WTP.
This project would require approximately 2,200 linear feet of 8-inch waterline from well 52 on 36th Ave NE to the intersection at Robinson Street. An existing 12-inch waterline will then be converted to a non-potable line as it moves west on Robinson Street before it combines with well 6 and the distribution system. In addition, two bores consisting of approximately 260 linear feet of 8-inch and 6-inch waterline under Robinson Street will be required to connect the neighborhoods on the north side of Robinson...
