Water well drilling for over 40 years

Sierra Exploration Drilling Company has been drilling water wells in the San Luis Obispo, Santa Barbara, Ventura and northern Los Angeles counties for over 40 years. In that time, our focus on drilling quality wells has led to the development of many innovations that provide for higher water yields and longer well life.

Having been in business for over 40 years, we have seen many changes in the water situation in California. We understand the need for water and the importance of conserving it at the same time; and strive to balance those in well drilling as well as pump servicing.

Drilling quality water wells at competitive prices goes hand in hand with our reliable customer service whether in drilling, pump installation, well maintenance, pump repairs or water testing. As a family business, we know that our reputation for integrity and hard work is central to keeping our good name.

Drilling Wells in California

County Departments of Public Health or local municipalities oversees the drilling and testing of residential water wells within designated cities and unincorporated areas. They also regulate any drilling moratoriums for the county. Their website provides a useful, informative, detailed pamphlet. Look for something like “Requirements and Procedures for Private Residential and Commercial Water Wells” which usually give step by step instructions for getting approval to drill and then use of a residential well. The pamphlets or websites detail steps thoroughly and also describes what to do if the water quality standards are not met.

Typical steps for approving a well may be:

  • Locate the County information on drilling and water quality
  • Submit a well permit application
  • Application is reviewed for completeness of information
  • Location is evaluated by an inspector
  • Work plan and application are reviewed
  • Inspector witnesses well seal installation
  • Well yield and water quality testing are performed
  • Final approval for use is granted
