Additional Backup Information: The Ullrich Water Treatment Plant (WTP) was built in 1969 and has a rated design treatment capacity of 167 million gallons per day. The plant is a conventional lime softening design, with up-flow solids contact reactor type clarifiers, gravity filters, clear well storage, and has raw water and finished water pumping stations. The plant has undergone several expansions and renovations over the years. It was expanded to its current treatment capacity in 2006. The Ullrich Water Treatment Plant is one of three water treatment plants serving Austin Water customers and it is the largest in treatment capacity. The amendment consists of the refurbishment or replacement of difficult to service centrifuges at the Ullrich WTP which have reached the end of its useful life and need replacement. Two of the centrifuges have been in service since 1986, and another set was installed in 2003. Replacing the two older centrifuge units and associated power distribution and controls with enhanced units that have modern monitoring and control capabilities. This will enable the plant to effectively process sludge waste out of the plant and provide the customers of the City of Austin with sustainable and reliable potable water. The services to be provided under this amendment are for design and bid phase engineering services relative to the centrifuges and control instrument improvements. There will be minimal impact to the public. All work will be located within the Ullrich WTP site boundaries, which is City owned property that is not open to the public. Delay or deferral of this contract will place an undue burden on operations of the Ullrich WTP, will have a negative effect on infrastructure stability and increase maintenance of the facility. Much of the equipment being replaced under this project is obsolete and no longer supported by the equipment manufacturers. Item 12 Water & Wastewater Commission: July 16, 2025 Council: July 24, 2025 AUTHORIZATION HISTORY AMOUNT DATE DESCRIPTION $2,000,000.00 08/09/2018 (Council) – Professional Services for UWTP Centrifuge Rehabilitation/ Replacement Project $1,000,000.00 $3,000,000.00 Total Contract Authorization 07/24/2025 (Proposed Council) - Additional Design and Bid Phase services CONTRACT HISTORY AMOUNT DATE DESCRIPTION $452,257.46 $75,007.72 04/18/19 Preliminary engineering services. 11/17/22 SA #1 – Add Phase D – Construction Services and Revise Phase A Preliminary Engineering Services ($9,577.22) $2,189,459.24 $2,707,147.20 Total Contract History 09/06/23 SA #2 – Remove Phase D Services and Add Phase B Design Services Proposed SA #3 – Add Phase B Final Design and Add Phase C Bid Services Item 12 Water & Wastewater Commission: July 16, 2025 Council: July 24, 2025 M/WBE Summary Participation goals stated in the original approved compliance plan for the agreement were 1.90% African American; 9.00% Hispanic; 4.90% Native/Asian American; and 15.80% WBE.
