Additional Backup Information: The contract will provide the City with approved original equipment manufacturer (OEM) electrolytic cells and repair parts provided by the contractor. This will achieve microbial inactivation requirements specified in the United States Environmental Protection Agency drinking water regulations administered by the Texas Commission on Environmental Quality and the more intensive City treatment goals. This is replacing a contract that will expire March 10, 2024. The requested authorization amount for this contract was determined using departmental estimates based on historical spending, along with a small annual increase to account for an increase in repairs due to aging equipment. The contractor is the sole manufacturer and supplier of the proprietary electrolytic cells. If the City is unable to secure a contract, proper maintenance and unscheduled repairs would not be accomplished, risking component failures. These failures will affect Austin Water Treatment Operations, limiting production of safe drinking water for the City.

Additional Backup Information: The City of Austin utilizes surface water resources from impoundments of the Colorado River for its potable water supply. Austin Water operates three existing Water Treatment Plants (WTPs), which are the Ullrich WTP, the Davis WTP and the Handcox WTP. The Ullrich WTP and Davis WTP draw water from Lake Austin and Handcox WTP draws water from Lake Travis. The Handcox Water Treatment Plant, located at 6800 RM 620 North, Austin, TX. 78732, was completed in 2014 and has a rated treatment capacity of 50 million gallons per day (MGD), in accordance with the operating permit issued by the Texas Commission on Environmental Quality (TCEQ). Since Winter Storm Uri, Austin Water maintains a minimum available treatment capacity from all three water treatment plants at all times, which limits the ability to take equipment offline for regular maintenance. During the original construction of Handcox WTP, process redundancy was removed to reduce construction cost. This project will bring Handcox to the level of process redundancy at Ullrich and Davis WTPs. The contract will provide qualified professional engineering services for the planning, design, construction, and warranty phase services for the Handcox Water Treatment Plant Resiliency Item 5 # 23-3894 Water & Wastewater Commission: February 14, …

Additional Backup Information: This action is one of four proposed Council items related to implementing Austin Water's new "GoPurple Program" to accelerate the expansion of Austin's centralized reclaimed system and onsite reuse. These are essential strategies in Austin's Water Forward plan to meet long-range needs for a secure and sustainable water future. GoPurple Program Austin Water continues to expand its centralized reclaimed water infrastructure (known as “purple pipe”) throughout Austin. This system delivers non-drinking water for irrigation, cooling towers, toilet/urinal flushing, and virtually any use not requiring higher-quality drinking water. Expanding the use of reclaimed water builds Austin’s resilience against drought and climate change by diversifying our water supply. Reclaimed water is a renewable resource that is less expensive to treat, and users are charged lower rates. All customers benefit from the expansion of the reclaimed water system, which is a key strategy in Austin’s Water Forward 100-year water supply plan. The GoPurple CBC will fund the reclaimed water system expansion as well as incentive programs to expand the use of reclaimed water within new development projects. Austin Water’s customers who are enrolled in the Customer Assistance Program (CAP) do not pay this Community Benefit Charge so their water and wastewater bills will not be impacted by this proposed increase. The impact will be a $1.47 monthly increase for the …
