This memo proposes recommended steps to attempt to mitigate water supply concerns with Well.5 currently out of service. Emergency Response Plan 1. Contract with Carollo — It is recommended that the City contract with Carollo to assist Utilities to diagnose, troubleshoot, and provide recommended solutions for the repair and return to service of Well 5. The contract would be a sole-sourced professional services agreementthat gets charged to the Water R&R fund. Staff is currently working ona scope, , .. budget, and sole source justification form now. Carollo is recommended to be sole sourced because we need a very quick turnaround on the investigations, and they are already familiar with Well 5 based on the current facility condition assessment CIP. - 2. Purchase Refurbished Motor/Pump—Pump Repair Service has confirmed that the motor and pump can be refurbished for approximately $100,000. The lead time would be about 8- 10 weeks. There is not a significant cost savings in a refurbished motor, but there is a significant savings in delivery time as a new motor was estimated to be 20 weeks out. A . - refurbished motor/pump, if approved immediately could potentially help get Well 5 operational by July when peak demands occur. The risk with procuring now is that there is a possibility that Carollo's simultaneous study finds the cause of this issue requires a different style motor and/or pump specification. Staff does not believe the risk of that occurring is high, but it is possible. Regardless, I recommend proceeding with the refurbished motor/pump-as soon as possible due to the bigger concerns of water supply capacity durinq the summer. I recommend you approve an emergency sole source purchase order to procure the motor/pump with Pump Repair Service due to its dollar value normally requiring council action. 3. Turnout 2 Commissioning Turnout 2 has not been operational for many years since it does not provide significant water supply benefits to the distribution system due to hydraulic limitations: However, Utilities believes it will not take significant resources to commission it. I have authorized staff to pursue this, as any additional capacity may prove valuable. 4. Coordination with Zone 7 for Temporary Increased Capacity out of TO3 and TO5— Historically, there has been limitations on the ability for Zone 7 to increase capacity out of these turnouts in coordination with how staff operates our system for water quality purposes. Staff is currently trending previous data to try to estimate the amount of increased turnout capacity we may need if Well 5 is not operational. Following that review, staff will setup a meeting with Zone 7 operations to discuss the potential for them to provide increased capacity during this period: 5. City Distribution Improvements Near TO3 — In order to try to move increased flow'from TO3 to where it is needed in the system, there is a pipe rehabilitation project at Hopyard/Owens that needs to occur beforesummer, but is not slated to start until fall of 2020 as part of a traffic related CIP project.-I have authorized Utilities to use their as-needed contractor to make a temporary repair now to bring the line into service as needed.
