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.

Dust monitoring, sound, and vibration reports
Valley Water's dust, noise, and vibration monitoring reports are under the "Reports and Documents" tab for review. In addition, all construction activities must comply with the Town of Los Gatos' noise ordinance. Our noise level monitoring is ongoing; data for that and vibrations are available under the "Reports and Documents" tab. These reports will be consistently updated. Please note that the Occupational Safety and Health Administration (OSHA) requires backup alarms on construction vehicles and cannot be turned off.

RWTP EIR Addendum 1: Work Schedules
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
The Rinconada Water Treatment Plant is Valley Water’s oldest treatment plant, having provided continuous and reliable service since 1967. While Rinconada primarily serves the west side of Santa Clara County, residents across the county contribute to the project funding through water rates.
