You’ve seen our map and you know we track Residential Recycled Water Fill Stations in the state of California. But did you know there are many that closed this winter that plan to re-open this summer?

I’ve spent the past few days calling each one and have great news! Most of your favorite fill stations have decided to turn the taps back on and will be opening or expanding their hours starting in May 2016. Which fill stations are they? Read on for details.

Updated 4/22/16: Delta Diablo to re-open on April 30, 2016 @ 9:00AM

If you would like to use any of this information for a news story, please give proper credit where due and reference with link backs as well. Thank you.

By using our list of fill stations in California (there are 23) we find that 10 closed for the winter. Nearly all of them have made the decision to re-open this summer. Some are still on the fence due to low user activity and high costs to operate. Plus, there are new fill stations coming, they’re just waiting on permit approval from the California State Water Resource Control Board.

Order below is opening or hours change by date.



Dublin San Ramon Services District

As the first fill station in the state and having 33 taps available for over 3600 registered users, Dublin San Ramon Services District sets the standard when it comes to Residential Recycled Water Fill Stations.

  • Wednesday, 9:00AM to 7:00PM
  • Saturday & Sunday, 9:00AM to 3:00PM

There are plans to re-open the Dublin fill station located at the Dublin Security Complex, but no date has been given for that yet.

Also – as demand picks up, more hours will be added.
