About Our District

Please check the website for current rates. We bill on a monthly basis. We use Chloramines in the water to disinfect which is a combination of chlorine and ammonia. There is fluoride in the water and the water is safe to use and drink. If you have a fish aquarium, you need to use a water treatment that you can find at any local pet store. If anyone in the home lives on a kidney dialysis machine, they must contact their physician for the water settings for the machine. We recommend that your outside watering should be no more than five (5) minutes at any one time.

Release of Liability

I request that Diablo Water District turn on water at the above service address regardless of anyone being at the premises. I realize that if all water-using appliances are not completely closed, or if there are any leaks, the premises may suffer water damage. I hereby accept full responsibility for any such damage and agree to hold Diablo Water District harmless if any damage should occur.
