State Water Efficiency and Enhancement Program (SWEEP)
Eligible practices include:
- Installation of a variable frequency drive
- Pump retrofit or replacement
- Soil moisture sensors
- Electronic weather station linked to irrigation controller
- Use of evapotranspiration (ET) based irrigation scheduling
- Conversion to micro-irrigation or drip irrigation
- Pump conversion from diesel to electric or to renewable energy such as solar
- Conversion to low-pressure irrigation system
What does this look like?
Here are a couple examples of successful SWEEP projects in the Central Valley :
- With SWEEP funds, farmer Pao Yang in Fresno County replaced valves and installed drip irrigation throughout the farm, resulting in significant water use and cost savings.
- He also halved his energy use and thereby significantly decreased his farm’s greenhouse gas emissions.
- The new, more efficient irrigation system has also decreased the number of weeds, which increases the farm’s profitability.
- The West Star North Dairy received funding to transform the irrigation system of their alfalfa field from flood irrigation to 2-set drip irrigation.
- They installed a flow meter to measure water use, a new 50hp booster pump with a 50hp variable frequency drive, and a soil moisture probe.
- The dairy can now decrease their greenhouse gas emissions using the more efficient variable frequency drive and by reducing the amount of flooding in their fields, which can lead to methane emissions. It also increases water use efficiency by installing drip irrigation instead of continuing to use the less efficient flood system.
How to Apply
The grant process includes a web-based application consisting of a series of questions that can be saved and returned to before submitting: https://www.cdfa.ca.gov/oefi/sweep/
Projects located in 'Severely Disadvantaged Communities' (SDACs) receive priority funding. For more info and to see if you are located in a SDAC, click here.
It is helpful to obtain quotes for projects and schedule a pump efficiency test before starting the application, as you will need them to complete the application. Here is more info about getting a pump test.
Please contact UC Cooperative Extension specialist Caddie Bergren at firstname.lastname@example.org for questions or help with the application.
