Martinez IV Collection System CIP – Project 29

Martinez IV Collection System CIP – Project 29

This project is for the design and construction of a large diameter gravity sewer line that will extend from Millican Drive to the Martinez IV Wastewater Treatment Plant (WWTP). This line was identified as Project 29 in the original Martinez IV Service Area Master Plan completed in FY 2017-18. Construction of this line is necessary to accommodate existing and planned development within the service area. Additionally, this line enables more connections in the service area north of Interstate 10 (I-10). Decommissioning of the Graytown Road and Millican Grove Lift Stations is also part of this project.

Mission Reach Area Maintenance

October 21, 2025

When: Beginning October 20, 2025 through Spring 2026
What: Crews will be performing stem-density removal and related vegetation maintenance along sections of the Mission Reach to help manage flood risk and protect surrounding infrastructure. Some trails or segments may be closed temporarily while work is underway.
Why: Removing excess stems that naturally establish along the river helps maintain stormwater conveyance, reduces flood risk, and protects public infrastructure while allowing grassland and native vegetation to recover and thrive.
What to expect:

  • Limited trail closures and intermittent work zones.
  • Crews and equipment working near the riverbanks during daytime hours.
  • Parking areas remain open, but visitors may see signage and temporary barriers.

Questions? Call the San Antonio River Authority at (210) 227-1373 or visit https://www.sariverauthority.org/services/river-health/ecosystems/.

Thank you for your patience while we keep the Mission Reach safe, clean, and enjoyable.
