On February 1 and February 15, 2017 outreach meetings were held for CAP water customers who will be affected by the 2019 Salt River Siphon Outage. At that time, CAP solicited input regarding water needs and timing for the outage for the fall or winter of 2019-20. Based on customer response, CAP maintenance needs, siphon project needs, and SRP maintenance schedules, CAP has selected October 30 through December 10, 2019 as the dates for the 2019 Salt River Siphon Outage. CAP has also coordinated with municipal providers that will be impacted by the siphon project and maintenance work on the SRP system. The proposed dates reflect coordination with SRP to ensure that a source of surface water will be available to municipal providers during the outage period.

The projected work schedule includes a full siphon dewatering, removing fish, coating analysis, and several applications of coating to over 400 pipe joints. As CAP continues to plan this work, Water Control and Engineering will be working closely with CAP Maintenance Planners to execute additional maintenance work downstream of the siphon. The siphon work itself will be subcontracted so the CAP maintenance force may be available to do other maintenance work along the canal.

There will be limited canal storage to meet demands during this period. The water in storage will be apportioned judiciously to assist customers in managing water supplies during the outage. CAP will work with customers to allocate available canal storage volume in the Fall of 2018 when the Annual Operating Plan is being developed for 2019. CAP will solicit canal storage requests from affected customers in conjunction with the regular 2019 water orders.

CAP appreciates all of the input received from customers and acknowledges that system outages of this magnitude require long lead times and careful coordination. CAP Water Control considers the proposed dates of October 30 through December 10, 2019 to be firm, but not final. If there are significant concerns or issues with the proposed dates of the outage, please feel free to contact the Melinda Whittington at 623-869-2573 or me at 623-869-2581 or by email at wateradmin@cap-az.com. CAP will be working to finalize the outage dates by 8/1/2017.
