Agenda Item ___11. February 27, 2019 Prepared by Terry Lauritsen Water Utilities I. SUBJECT, ATTACHMENTS, AND BACKGROUND Discuss and take action to approve the final report for a Water Reuse Feasibility Study completed through a Bureau of Reclamation grant to augment Bartlesville’s Long Term Water Supply. Attachments: Title XVI Feasibility Study Report – Augment Bartlesville Water Supply with Drought-Resilient Reclaimed Water II. STAFF COMMENTS AND ANALYSIS Over the last 12 years, the City has been experiencing consistent flows into the wastewater treatment plant that have exceeded the plants rated design capacity. Due to the frequency of these flows, a facility plan was initiated in 2004 and completed in 2010 to investigate options to either expand the current treatment plant or build a secondary treatment plant south of town. Based on the City’s growth patterns, comparable capital costs and long-term desire to move the treatment plant away from populated areas, Council selected the secondary treatment plant south of town option. After the completion of this facility plan (2010), the state legislature adopted the Water for 2060 Law, which has a goal to consume no more fresh water in 2060 than consumed in 2012 and tasks the Oklahoma Department of Environment Quality to develop regulations and encourage water reuse. Bartlesville has a desirable layout regarding the location of the existing wastewater treatment plant and a potable raw water pump station on the Caney River, which is shown below. Page 1 of 2 Since water reuse was not considered in the 2010 facility plan, Council approved a contract with Tetra Tech in May 2016 to investigate the feasibility of reuse and update the costs for the two options developed through the 2010 facility plan. In August 2017, the results from the study were presented to Council, which concluded that water reuse is feasible up to 4 million gallons per day and the capital costs to build a secondary plant south of town was $65MM, while the cost to expand the existing treatment plant was $49.4MM. In September 2017, Council selected the option to expand the existing treatment plant and authorized staff to pursue water reuse through this option. In January 2017, the City applied for a $150,000 grant through the Bureau of Reclamation’s (BOR) WaterSMART program to pursue a feasibility study for water reuse. In October 2017 the City was awarded the grant. While some of the tasks necessary for the feasibility study were completed through Tetra Tech’s May 2016 contract, Council approved an amendment to the 2016 contract in October 2017 for additional analysis and sampling necessary for regulatory approval to complete this feasibility study. The final report for the feasibility study is complete, which is attached, and will be presented to Council at its March 4th meeting. III. RECOMMENDED ACTION Staff recommends approval of the final report for the water reuse feasibility study.
