Austin Water’s FY25-29 CIP Plan includes projects located across the Austin metropolitan area, including the Drinking Water Protection Zone (DWPZ). In compliance with Austin Water’s Financial Policy No. 8, the capital improvement projects for new water and wastewater treatment plants, capital expansions, and growth related projects that are located in the DWPZ are presented below for consideration by City of Austin Boards and Commissions. These projects represent improvements required to meet Austin Water standards for operability and customer service. While additional capacity may be added in accordance with current design standards, the intent of these projects is to meet the demands of existing or agreed upon future customers rather than promoting additional growth. A map showing specific project locations is provided along with additional project information in the appendix. Table 1.

Planning Phase new infrastructure projects in the Austin Water Capital Improvement Program Plan Proposal impacting the City of Austin Drinking Water Protection Zone. Subproject Subproject Description 1) Southwest Parkway Southwest B Elevated Reservoir (2127.016) Construct a 2-million gallon elevated reservoir on Southwest Pkwy near Amarra Drive. FY25-29 Spending Plan $18.74M FY30+ Spending Plan $0.06M Total $18.80M 2) Marshall Tract (3353.127) Cost reimbursement project located at 1300 Lost Creek Blvd for $6.07M $0.00M $6.07M elevated water reservoir and approximately 4,000 feet of 16-inch water main. Davis Water Treatment Plant flows are limited into the Central Pressure Zone transmission system. Additional transmission capacity is needed to meet additional system demands and increase system resiliency. Construct 3,700 linear feet of 24-inch water main along Southwest Pkwy from Terravista Dr. west to a new elevated reservoir. Construct 6,600 linear feet of 24-inch water main along Old Bee Caves Rd. and Travis Cook Rd to the new elevated reservoir. The project includes design and construction of improvements that may include a roadway expansion from two lane section to a four lane divided roadway, signals, medians, waterlines, bicycle and pedestrian facilities, and driveway reconstruction. Flows at Rock Harbour Lift Station have exceeded design capacity and is at risk of wet weather overflows. This project will increase the firm capacity and address operations and maintenance concerns as identified by the Northwest Lift Station Study. Improvements to the Barton Creek Plaza Lift Station that will enable it to better handle existing flow. 3) Davis Medium Service Water Transmission Main (6935.001) 4) Southwest Parkway Transmission Main (6935.025) 5) Spicewood Springs Road Regional Mobility Improvements (11880.001) 6) Rock Harbour Lift Station Improvements (3168.057) 7) South Area Lift Station Improvements: Barton Creek Plaza (3168.076) 8) Northwest Area Lift Station Improvements: Boulder Lane Lift Station (3168.085) 9) Barrington Oaks Downstream Gravity Improvements Phase 2 (6943.041) 10) Boulder Lane at Crossland Drive Wastewater Improvements (6943.087) Flows at Boulder Lane Lift Station have exceeded design capacity and is at risk of wet weather overflows. This project will increase the firm capacity and address operations and maintenance concerns as identified by the Northwest Lift Station Study. Replace and upsize existing 12-inch gravity line from manhole 114641 to manhole 42304 to increase capacity. The existing line is in poor condition and reaching capacity limitations. The project length is approximately 3,000 linear feet. A segment of 8-inch wastewater pipe at Boulder Ln. and Crossland Dr. needs to be upsized to provide capacity for existing flow and approved development and to prevent overflows in an environmentally sensitive area. * new to 5YR plan $19.00M $170.05M $189.05M $8.59M $1.14M $9.73M $8.51M $0.00M $8.51M $1.01M $0.00M $1.01M $0.34M $8.26M $8.60M $5.26M $0.25M $5.51M $0.56M $3.46M $4.02M $0.16M $0.04M $0.20M Revised 3/15/2024
