Water Treatment Process

The City of Lompoc uses a conventional treatment process to ensure the safety and quality of our drinking water. Our process consists of disinfection, coagulation, flocculation, sedimentation, and filtration with diatomaceous earth (DE). Constructed in 1964, the treatment plant was originally designed to allow filtration of approximately 6 million gallons per day (MGD). With some enhancements and additions of filters, our capability is now approximately 10 MGD.

The City of Lompoc is also responsible for the operation of Frick Springs treatment plant. This plant consists of a small diatomaceous earth (DE) filtration and disinfection system. The water treated at this plant is collected from seven springs located in the upper hills. Frick Springs water treatment plant must comply with the Surface Water Treatment Rule (SWTR).

City Of Lompoc's 2015 Urban Water Management Plan (UWMP)

The City’s 2015 UWMP is a five year water plan, which is required by the California Department of Water Resources for all urban water suppliers which supply 3,000 acre feet of water yearly or have 3,000 customers. The purpose of the UWMP is for urban water suppliers to review and evaluate their long-range water plans and to make sure that there is adequate and reliable water to meet the present and future water demands. The UWMP provides a framework to help water suppliers maintain efficient use of urban water supplies, continue to promote conservation programs and policies, make sure that sufficient water supplies are available for the future, and provide a plan for responding to water drought conditions.

City Of Lompoc's Groundwater Management Plan

The City prepared a State mandated Groundwater Management Plan (Groundwater Plan) in November 2013, because it relies on groundwater to meet the water demands of its customers. The primary purposes of the Groundwater Plan are to:

  1. Develop measureable Best Management Practices, which apply to the City’s service area;
  2. Develop baseline conditions for the City, which is located in the Lompoc Plain Sub-Basin;
  3. Develop a mechanism for continued collection of groundwater and aquifer information. An aquifer is an underground layer of water-bearing rock, from which groundwater can be extracted using a water well;
  4. Develop a framework for reviewing possible changes to the baseline conditions;
  5. Develop a mechanism for updating the Plan as conditions change and new information is available.
