Fleming Tank, Pump Station Project

Fleming map

Irvine Ranch Water District is upgrading its drinking water tank and pump station at Santiago Canyon and Silverado Canyon roads. The project started construction in the fall of 2022.

This project will enhance drinking water storage and pumping reliability for customers of Santiago, Silverado, Williams, and Modjeska canyons, and will also be available for emergency fire conditions. (Click here to view a draft rendering of the project.)

The project includes:

  • •  Replacement of the existing 150,000-gallon steel storage tank with a 1.3 million-gallon concrete tank.
  • •  Replacement of the existing pump station with a new, state-of-the-art pump station to increase pumping reliability and redundancy.
  • •  A new pump building with space to serve as an outpost for the District in emergencies.
  • •  New disinfection facilities for water quality management.
  • •  A new building (approximately 1,000 square feet) to house IRWD equipment that is routinely used throughout the canyon areas.
  • •  Miscellaneous improvements to the site and the existing electrical and instrumentation systems.

The existing facilities will remain in service during construction of the new facilities to ensure uninterrupted water delivery to our customers. For more information, please contact IRWD Public Affairs at info@IRWD.com or 949-553-5500.
