Annually, Sonoma Water develops a Capital Projects Plan that describes the infrastructure projects that are planned for the next five years.  These projects are designed to meet regulatory requirements and also replace aging facilities.  Below is the list of projects that are currently out to bid.

List of Projects

For Projects Out-to-Bid, bidders may obtain electronic Bidding Documents on the Sonoma Water Portal. Bidders may obtain printed Bidding Documents as described in the advertisement for bids for the project.

Registration in the Sonoma Water Portal is required to view Bidding Documents. Viewing a Bidding Document automatically adds you as a Plan Holder for that project, and you will receive email notifications should any addenda be released for that project. You can receive email notifications when new bids are posted by registering in the Sonoma Water Portal, selecting "My Subscriptions" and selecting the "Projects Out To Bid" category.

Bidder questions may be submitted via email to: BidderQuestions@scwa.ca.gov. Please identify the specific project to which you are referring in the title of the email. If questions are received within the time specified in the Bidding Documents, and if Owner determines that a response is necessary, Owner will transmit answers in the form of an addendum (or addenda) to all parties recorded as having received Bidding Documents (planholders list). Responses to some questions may be delayed so that addenda may address several issues at once. Owner will attempt to address questions in a timely manner to allow sufficient time for Bidders to prepare their Bids. Please refrain from contacting staff by phone or email so that we have time to adequately address your question and process addenda, if appropriate.
