Council Committee, Boards and Commission Action: April 15, 2026 - To be reviewed by the Water and Wastewater Commission. Additional Backup Information: Austin Water’s water distribution system is fundamental for the conveyance of water to customers. The water distribution system is a large and complex system, consisting of approximately 3,900 miles of water mains and serving approximately one million customers. Due to age, growth, and system expansion, water distribution system assets require upgrades to meet customer demand needs. The Oltorf at Travis Heights Pressure Zone Conversion project will convert residences and businesses in the project area from the Central Pressure Zone to the higher-pressure South Reduced Pressure Zone to provide improved pressures and fire flows. The work includes installation of approximately 3,800 linear feet of 6-inch, 8-inch, and 12-inch ductile iron water mains, 12 water services, 2 pressure reducing valve vaults, and approximately 490 residential pressure reducing valves (PRVs) on Mariposa Drive, South Congress Avenue, East Oltorf Street, St Edwards Drive, Alta Vista Avenue, Rebel Road, Algarita Avenue, Rosedale Terrace, East Live Oak Street. This item includes four allowances. An allowance of $50,000 is to address contaminated soil that may be encountered during construction; an allowance of $40,000 is to replace possible deficient valves found during construction; an allowance of $700,000 is for any work that may be needed on private property per City of Austin plumbing code after the installation of individual PRVs ; and an allowance of $50,000 is to cover the cost of any work stoppage required due to potential archeological discovery on site. An allowance is an amount that is specified and included in the construction contract or specifications for a certain item(s) of work whose details are not yet determined at the time of bidding. Item 10 Water & Wastewater Commission: April 15, 2026 Council: May 21, 2026 Due to the potential for encountering unknown underground utilities during construction, a 10% contingency in funding has been included to allow for the expeditious processing of any change orders to cover any unforeseen construction costs associated with the project. Construction activity will occur primarily within Austin’s right of way. During construction, temporary lane closures will be in effect on streets where water lines are installed. The project proposes lane closures and/or detours during off-peak traffic hours, and the contractor will install appropriate traffic detour signs and barricades to direct traffic. The contractor will work to ensure that residents always have access to their driveways. If access cannot be maintained, written notice of limited access will be provided to the affected property owner(s) at least 24 hours in advance. In addition, there will be planned temporary water service interruptions, primarily during pipeline tie-in and service reconnection. Residents will be notified at least 48 hours in advance of planned service interruptions. This construction contract is time sensitive and is a critical component of maintenance and service of the water distribution system. Delay or deferral of this contract may impact the ability to provide adequate pressure and fire flows. The contract allows 425 calendar days for the completion of this project. This project is located within zip code 78704 (Council Districts 3 and 9).
