Title
AMENDMENT NO. ONE TO CONTRACT K-1920-115: BY AND BETWEEN THE NORMAN UTILITIES AUTHORITY & GARVER, L.L.C., INCREASING THE CONTRACT BY $2,890,910 FOR A REVISED CONTRACT AMOUNT OF $3,424,160. FOR FINAL DESIGN, INSTALLATION AND OVERSIGHT OF A TEMPORARY RESEARCH PILOT FOR INLAND INDIRECT POTABLE REUSE LOCATED AT THE NORMAN WATER RECLAMATION FACILITY AND BUDGET APPROPRIATION.
Body
BACKGROUND: The Norman Utilities Authority (NUA) and Garver LLC (Garver) were recently selected as recipients for the Bureau of Reclamation (BOR) Water Reclamation and Reuse Research under the Title XVI Program for Fiscal Year 2019 Funding Opportunity Announcement BOR-DO-19-F009. The BOR grant will provide $700,109 towards the NUA pilot project and will reimburse a portion of the NUA funds expended.
On February 11, 2020, the NUA approved contract K-1920-115 with Garver to perform a pilot project evaluating various advanced treatment technologies that could lead to indirect potable reuse (IPR) at Lake Thunderbird. Garver's in-depth experience during design of our recent Water Reclamation Facility (WRF) expansion, upgrades and improvements made it an obvious decision for staff to collaborate with Garver to perform this pilot project at the WRF.
This temporary pilot project will investigate and compare 1) two biological nutrient removal (BNR) technologies; 2) three or four pilot-scale filter technologies to meet very low effluent nutrient levels; and 3) advanced oxidation processes (AOP) for removal of constituents of emerging concern (CEC's). The pilot study will extend over a 30-month timeframe to ensure the treatment technologies tested can accommodate seasonal weather conditions that could affect treatment efficiencies.
The pilot project will utilize two of the six aeration basins and two of the six secondary clarifiers to establish two parallel treatment trains. One batch treatment train will process up to 200,000 gallons per day (GPD) while the other steady state tr...
