County Requirements
The Orange County Well Ordinance (County Ordinance No. 2607) requires that a permit be obtained prior to the construction or destruction of any well. In unincorporated County areas and in twenty-nine of thirty-four Orange County cities, the Orange County Health Officer is responsible for enforcement of the well ordinance. In the remaining five cities (Anaheim, Buena Park, Fountain Valley, Orange and San Clemente), well ordinances are enforced by city personnel. If you have any questions, please feel free to contact us at 714-433-6287 or 714-433-6285 or email EHOCWells@OCHCA.COM.

Permits are specifically required for all wells and soil borings except:

- do not penetrate significant confining material beds.
- Oil and gas wells, geothermal wells or other wells constructed under the jurisdiction of the State Department of Conservation, except those wells converted to use as water wells;
- The EPA exempts permit requirements for well construction and destruction activities conducted at the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) sites, commonly known as Superfund.
To expedite the permit approval process, all the necessary attachments and applicable fees should be submitted with the permit application. The required attachments include a site plan showing the locations of all wells (proposed and existing), potential sanitary hazards and a well construction diagram. The diagram should include, at a minimum, materials of construction, depth of seals, borehole diameter, size of casing, depth to first groundwater and total depth of wells. Please note that the permit approval process may take a minimum of 10 business days depending on the complexity of the project.
A permit shall remain in effect for one year from date of issuance.
