California's Water Industries
Providing Data Driven Information
California is experiencing a severe drought that has resulted in water rationing, fewer agricultural crops, the loss of thousands of jobs, and an overall decline in the state’s economic health. Further, the demand for water continues to increase as the state’s population grows. As such, water and waste management efforts are necessary to ensure that future generations have access to freshwater.
The following studies approach water industries and their related occupations from different angles but with a common theme - responsible management and conservation of water resources.
Reports and Research
New! Bay Region
Water & Wastewater Occupations (pdf) - December 2009
In 2009, the Bay Region COE and the Bay Area Water/Wastewater Workforce Development Collaborative (BAYWORK), conducted a survey of water and wastewater utilities and agencies across six Bay Area counties. Based on these survey results, employers are projected to need as many as 677 new and replacement workers in seven mission critical occupations over the next five years. Download the complete environmental scan or key findings from the survey.
New! Water Sector Competency Model
The American Water Works Association (AWWA) worked with its membership to identify the occupation specific competencies required for workers in the water sector. The results of those efforts were formatted into a competency model (pdf), using an Employment and Training Administration (ETA) framework. The resulting model, which depicts the core competencies required for field staff and operators, is an excellent resource for workforce developers and educators.

Greater Sacramento Region
Water Efficiency Technology (pdf) - October 2008
Drought, climate change, and population growth are depleting California’s water supply, creating an unreliable system and increasing the need for water efficiency technology. This study assesses the training and workforce needs of the plumbing sector related to recent technological advancements and building code changes.
Los Angeles Region
Water Operators in Los Angeles County (pdf) - April 2008
Water distribution, water treatment, and wastewater treatment are essential industries that are generally run by public utilities and taken for granted by most citizens. Heightened security concerns since 9/11, new technologies, and continually increasing demand for water are some of the trends that are putting pressure on the industry to expand and evolve.
