CONTRACT NO. K-1314-98: A CONTRACT BY AND BETWEEN THE NORMAN UTILITIES AUTHORITY AND PROFESSIONAL ENGINEERING CONSULTANTS, P.A. IN THE AMOUNT OF $218,900 TO PROVIDE ENGINEERING SERVICES RELATED TO THE DESIGN, BIDDING AND CONSTRUCTION OF A ONE MILLION GALLON ELEVATED WATER STORAGE TANK LOCATED IN NORTHEAST NORMAN AND BUDGET TRANSFER.
Body
BACKGROUND: The addition of another elevated water storage tank has been envisioned by the Norman Water Utility for several years. The existing water distribution system has four elevated storage tanks with a capacity of 4.5 million gallons (MG), as follows and as illustrated in the attached map:
Cascade Tower, steel/concrete composite tank with capacity of 2 MG;
Brookhaven Tower, welded steel tank with capacity of 1.5 MG;
Boyd Tower, welded steel tank with capacity of 0.5 MG;
Robinson Tower, welded steel tank with capacity of 0.5 MG.
Additionally, 7.5 MG of underground water storage is provided at the Water Treatment Plant (WTP) in two "clearwells" for a total storage capacity of 12 MG. Distribution pumping at the smaller 1.0 MG clearwell feeds the high pressure plane (HPP) in northeastern Norman while pumps from the larger 6.5 MG clearwell feed the four existing storage tanks and the remainder of the Norman distribution system.
Two other storage tanks exist in the system but are not usable due to their elevation: the Lindsey Tower, a welded steel tank with capacity of 0.5 MG; and the Hall Park Standpipe, with a capacity of 0.3 MG.
Computer modeling of the water distribution system indicates the greatest need for elevated storage is in the High Pressure Plane (HPP) in northeastern Norman. There is no elevated storage currently in the HPP; water pressure is provided via four constant speed pumps at the 1 MG clearwell. In the event of a power failure or a water line break, water pressure in the HPP is reduced relatively quickly. The construction of the elevated storage tank will provide storage to m...
