Rinconada Water Treatment Plant Reliability Improvement

About This Project

The Reliability Improvement Project is aimed at retrofitting, upgrading and/or replacing key equipment that is reaching the end of its natural life, addressing the areas of raw water ozone, flocculation and sedimentation. Filtration and redundant disinfection.

The work will also increase the plant’s treatment capacity from 80 million gallons of water a day to 100 million gallons a day and help the district meet increasingly stringent standards for water quality, seismic stability and safety.

Public meeting held Feb. 29, 2024

Thirty-five neighbors of the Rinconada Water Treatment Plant attended Valley Water’s Feb. 29 public meeting to hear about upcoming construction plans and learn about plant operations during a brief facility tour. A video of the meeting will be available soon on Valley Water's YouTube channel. 

Deputy Operating Officer Sam Bogale speaks to Rinconada neighbors about the clarifiers and how their upcoming demolition will benefit the treatment plant.

Environmental & Community Benefits

The Reliability Improvement Project will replace or upgrade all major plant components and increase Rinconada’s treatment capacity to 100 million gallons of water a day. These enhancements will also result in improved taste for your drinking water. The Project includes the design and construction of new facilities, including raw water ozonation, flocculation and plate settler clarification and dual media filtration. This work will also help the district meet increasingly stringent standards for water quality, seismic stability and safety.

This completed project will use the following steps in drinking water treatment:

  • Raw Water Ozone
  • Flocculation and Sedimentation
  • Filtration
  • Redundant disinfection
