Water Well Permitting

The Environmental Health Division issues permits to construct new water wells, reconstruct, repair or deepen existing wells and destroy abandoned wells to properly licensed water well drilling contractors in unincorporated Fresno County. For water well issues within any of the incorporated cities in the County, please contact the city in question directly.

Fresno County Department of Public Health, Environmental Health Division enforces the provisions of the California Well Standards Ordinance and the construction standards set forth in the California Well Standards, Bulletins 74-81 and 74-90.

Only persons who possess an active C-57 Water Well Contractors License may perform construction, reconstruction or destruction work on wells.

It order to obtain a permit to drill a well, properly licensed contractors shall submit a completed Water Well Permit Form, along with applicable permit fees, to this office. The application will be reviewed, and if found acceptable, will usually be approved within two working days. Once the permit application is approved, a well permit number will be assigned and drilling may commence. The permit is valid for 180 days.

The California Well Standards Ordinance requires contractors, as part of the well construction process, to install an annular seal of at least twenty (20) feet in depth (fifty [50] feet for public water system wells or industrial wells) to help protect the well from contamination.

The California Well Standards Ordinance also requires contractors to notify our office at least twenty-four (24) hours in advance of the scheduled time to install the annular seal so that Environmental Health staff can arrange to inspect the seal installation process. This inspection helps to ensure that the seal is installed in an approved manner to help prevent contamination of the well water.

Annular seal appointments may be scheduled by contacting the Water Well Permitting Program at (559) 600-3357.

Once the well construction, deepening, or destruction work is completed, the contractor is required to provide a Notice of Completion, also known as a Well Driller’s Report or Well Log, to our office within thirty (30) days of completion. The report shall document that the work was completed in accordance with the Well Standards Ordinance.

Consumer Information

Owners of property located in the unincorporated areas of Fresno County who are planning to have a well drilled on their property must contact a properly licensed driller to obtain a permit to drill a well from this office. Once approved, the permit will be issued to the water well drilling contractor who will be performing the work. Please see the water well permitting information to review what is required of the water well drilling contractor.

Once construction of the new well is completed, the contractor is required to provide a Notice of Completion, also known as a Well Driller’s Report or Well Log, to our office within thirty (30) days of completion. Once our office receives this document, we will contact the property owner by letter to schedule a Final Inspection of the new well. This inspection will help ensure that the well has been completed in an approved manner and there are no apparent direct openings into the well that may allow the entry of contamination into the water supply. During this inspection, Environmental Health staff will, if possible, conduct sampling of the water in new or deepened domestic wells to determine if there are certain contaminants of health concern in your water. Please be advised that private wells are not required to meet any water quality standards. The sampling is conducted as a service to you to help protect your health and the integrity of our groundwater resource. The sampling is free of charge at this time.

Abandoned Well Information

A well is considered “abandoned” when it has not been used for a period of one year unless the owner demonstrates his intention to use the well again for supplying water. The California Well Standards Ordinance requires that all abandoned wells must be destroyed. If you have an abandoned well and are considering using the well again, please refer to the Requirements for Maintaining an Inactive Well. If you do not plan to use the well again, please refer to the Well Destruction Requirements.
