Drilling a Water Well

If you are planning on building a home in a rural location with no access to public drinking water, you will have to drill a well on your property.  Water well permits may only be applied for by a licensed well driller (see procedure below).  Please see our FAQ's for common questions regarding water wells.

The City of Roseville has separate permitting requirements and must be contacted if the well is to be drilled within city limits.

Any wells planned within the City of Lincoln must first be approved by the City, prior to issuance of an Environmental Health permit. 

Please review our website for information regarding monitoring wells, cathodic protection wells, and exploratory soil boring.

Water Sampling

If you own a home with a water well, you may be required to sample your water to determine if it is safe to drink for the purposes of issuing and approving permits for Building, Planning, and Environmental Health.  Sampling may be for bacteriological testing or chemical testing (nitrates, for example).  Sampling must adhere to very strict protocol, so please refer to our water sampling guidelines prior to attempting to take a sample. 

Drinking water bacteriological testing samples must be submitted to a California Certified Environmental Laboratory.

Please contact us if you have any questions regarding sampling.

Water Well Disinfection

There may be times when your well needs to be disinfected, such as:

  • After construction of a new water supply or pipeline.
  • After making repairs to an existing water supply.
  • After a water system has been unused for several months.
  • After surface flooding of a well or storage tank.
  • When the results of a bacteriological test indicate contamination.
  • Before a new water supply (ie. well) is used.

Please refer to our detailed disinfection procedure.

Applying for a Well Permit

Well Permits must be applied for by a licensed well driller with a C-57 license. Upon applying for a permit, the Driller shall provide the following:

  • A vicinity map and clear directions to the property and well site.
  • Plans and specifications for the proposed work, including method of sealing the annular space.
  • Two copies of an accurate site plan, drawn to scale. Show the proposed well location and all features of potential contamination such as septic system, sewer line, animal feed lots or pasture, and property lines within 150 feet of proposed well site. Wells are required to be in compliance with set-backs from potential ground water hazards.
  • A copy of the Assessor's plot map/parcel map.
  • Location of any restrictions such as easements on the property.
  • Any other information that enforcement agency finds necessary to complete the permit application.
  • Submission of the appropriate permit filing fee.

Once the above documentation has been reviewed and approved by our Specialists, drilling may commence.  The permit must be on-site during the drilling process and the driller must comply with  the permit requirements and the Placer County Well Ordinance.
