On June 12, 2017, a letter was sent out to our water users indicating that CAP had held outreach meetings and solicited input regarding projected delivery needs during a six week outage in the fall of 2019. Based on responses and CAP maintenance needs, CAP has selected October 30 through December 10, 2019 as the final dates for the 2019 Salt River Siphon Outage.
As with our previous correspondence, the projected work schedule includes a full siphon dewatering, removing fish, coating analysis and application of coating to over 400 pipe joints. The siphon work will be subcontracted so that CAP maintenance staff 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 water users 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 water users in conjunction with the regular 2019 water orders.
These outages have been coordinated to have minimal impact on our water users. As we continue to work with our maintenance and engineering groups to develop the plan of work, we will continue to communicate with you as we reach milestones in the process. If you have any questions, please feel free to contact me at 623-869-2581.
