Well Permit Applications can only be applied for by a licensed California Well Driller. This can be done online through our Accela Online Citizen Access Portal. Please contact a Licensed California Well Driller if you plan on drilling a well. 

Please keep in mind that a well permit expires one year after the permit issuance date.

After Installation

The Environmental Health Department requires the following well testing to be done prior to being hooked up to new residences:

  • Well Yield Test is a four hour pump test to determine if the well can produce at least 3 gallons/minute sustained production rateThe well ordinance can grant approval for a Certificate of Occupancy for well production as low at 1 gallon/minute with a required minimum 1000 gallon holding tank. 
  • Raw Water Certification is a bacteriological test performed by a California State Laboratory that determines if there are any coliform bacteria present in the water. Coliform bacteria are indicator organisms that are readily found in soil, decaying vegetation, animal feces, untreated surface water and  may be accompanied by pathogens. The sample is taken by a Nevada County Environmental Health Specialist and requires a fee.
