 San Joaquin Valley Agricultural Drainage

Canal
Drainage
The Agricultural Drainage Program collects, evaluates, reports information and conducts studies and demonstration projects focusing on drainage problems in the San Joaquin Valley. The resulting data and information on agricultural drainage issues enable better definition of drainage problems and lead to implementation of management plans.
 
Agricultural Field
Integrated Drainage Management
Integrated On-Farm Drainage Management (IFDM) is a state-of-the-art management system that provides for drainage water reuse to improve water availability for crop production and to minimize salt and selenium risks to water quality and the environment.
 
Solar Pond
Drainage Treatment
Investigate technologies for treating agricultural subsurface drainage water. Technologies involve removing salt by reverse osmosis, reducing and removing selenium through biological processes, and managing salt by using solar salt-gradient ponds and agro forestry.
 
Field Monitoring
Drainage Monitoring
Determine the aerial extent of drainage problem areas (groundwater level within 20 feet of ground surface) and the quality and quantity of subsurface drainage for the San Joaquin Valley. Collect, maintain, and evaluate water quality data and produce the annual San Joaquin Valley Drainage Monitoring Report.
 
RO Effluent
Desalination
Provide technical assistance concerning desalination and advanced treatment of brackish agricultural wastewaters – including process selection, economic factors, operations and maintenance, environmental requirements, and pilot treatment studies.
 
Clean Air
Proposition 204
Under The Safe, Clean, Reliable Water Supply Act, the Department seeks to develop methods of using and concentrating salts, and reducing contaminants in the State’s subsurface agricultural drainage water by soliciting proposals from public entities seeking funding for research activities consistent with the goals of the program.
