And here is a list of resources you might want to download or access:
Private well owners - Wells are the jurisdiction of the Santa Clara Valley Water District (SCVWD). Well installations and removals must be coordinated through them. You can find a link to the Well-related portion of its web site here.
As a courtesy to our customers who are interested in having an existing well removed, we provide links to the SCVWD’s Well Guidelines and Demolition Applications below. Please note that well documents are the property of the Santa Clara Valley Water District and may change without notice. To be sure you are reading the most up-to-date information, you should contact the SCVWD directly.
The City of Palo Alto does require backflow prevention on all water services to any properties with wells. This will include any properties served or crossed by well service; even if the well is not at that property.
If you have any questions or concerns about whether you fall under the mandatory requirement to install backflow prevention devices, please feel free to call our staff at (650) 496-5926 or email us.
