Title
Authorizing the City Manager to execute a Facility Extension Agreement with Oncor Electric Delivery to provide a redundant electrical service to the Surface Water Treatment Plant in the amount of $353,406.86.

Summary
As has been noted on previous City Council items, the Surface Water Treatment Plant and Lake Pump Station currently do not have backup power supply in the event of an extended power failure as was experienced from February 15, 2021 to February 17, 2021. This creates a significant risk for the City’s Public Water System as the plant produces most of the water that is used within the City. Due to this risk and the need to make the City's water system more resilient in the event of an emergency, the City Council approved a professional services agreement with Gupta and Associates, Inc. on September 22, 2020 to design the emergency generator power system. The design of the standby generator system has begun and the installation of the generators will allow the City to continue producing water in the event of a power failure affecting the Surface Water Treatment Plant and Lake Pump Station.

City staff gave an update to City Council on March 23, 2021 which provided for various redundant power options for both the Surface Water Treatment Plant and the Lake Pump Station. During this update, it was explained that we can work with Oncor to provide a secondary redundant feed to the Surface Water Treatment Plant from a separate substation. In addition to this, City staff is currently expediting the Surface Water Treatment Plant generator by finishing the purchasing scope for the generator so the City can pre-purchase the equipment to minimize the amount of time the construction will take to bring online at the facility. The current design for the Surface Water Treatment Plant generator project is scheduled to be completed by the end of September 2021. The project will then be bid and a construction contract brought to City Council in October 2021....
