Well Setbacks


  • Codes and regulations that govern the installation of a well, including an ag well: California Well Standards published by Department of Water Resources
  • Cost of Environmental Health permit: NEW INSTALLATION PERMIT – AG (P/E 4102) = $813.  Note: the cost of drilling a well varies significantly depending on the construction design of the well (such as the diameter and the depth).
  • Permit Application Form: While the well owner or the C-57 well driller can sign the permit application (link above), a C-57 licensed well driller must be identified for the work. Most of the time the well driller completes the application form. A non-inclusive list for the well drillers is linked above.
  • Setback requirements: See related link above. The setback to the leach field does not apply to the abandoned one. However, it does apply to the 100% replacement area (an area of land dedicated for replacement of an entire septic system upon its failure). For properties connected to the City sewer system which have no septic system on site serving as a back-up, this setback to the 100% replacement will not apply.  Note: all set-back requirements, such as wells to septic tank/leach field (replacement area included) and sewer line will include those site features located on one's own parcel as well as neighbors' parcels.
