First Aqueduct Structures Rehab

Project Background

Project Map

The southern First Aqueduct delivers untreated water from Escondido throughout southeast San Diego County. Pipeline 1 and Pipeline 2 structures built in the late 40s and early 50s require maintenance to continue providing water to our member agencies. This project rehabilitates, abandons, or replaces 110 structures over 19 miles of the southern portion of the First Aqueduct.

Blow off structures will be demolished and reconstructed to current standards, air valve and manway structures will be rehabilitated by construction of new access lids. All new structures will include new piping, mechanical, and other appurtenant improvements.

Project Status: Future

  • Construction begins: Fall 2023
  • Construction ends: Fall 2025
