SWEEP grants encourage producers to reduce both their water consumption and their greenhouse gas emissions. Successful applications   must increase water efficiency and demonstrate the impact that the project will have on emissions. CDFA will award funds up to $100,000 but also encourages applicants to find matching funds.


Eligible practices include:

What does this look like?

Here are a couple examples of successful SWEEP projects in the Central Valley :

  • Vegetables
    • 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.
  •  Almonds

  • Alfalfa
    • 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 - click here to start your application.

Before you apply, you will need to gather three main pieces of information: 

1. A pump efficiency test. For more information on how and where to get a pump test, click here. PG&E customers are eligible for a subsidy that pays for most of the cost of this testing.

2. The last twelve months of your energy records.

3. Quotes from vendors for the costs of your project components and installation. 

Please note: The online application can be difficult, so we strongly encourage you reach out for free technical assistance in writing your application. Contact Caddie Bergren at (209) 385-7403 for questions and assistance. 

There will also be a SWEEP workshop with irrigation specialist Dr. Khaled Bali on:

Thursday, November 7th, from 1:00pm-3:00pm at the Merced Cooperative Extension office (2145 Wardrobe Ave, Merced, CA 95341).

Please RSVP to the office at (209) 385-7403 or cmbergren@ucanr.edu.


Projects located in "Severely Disadvantaged Communities" or SDACs will receive priority funding. To determine if you are in one of these areas, click here.


The grant application period is open starting October 21st, 2019 and will close in December 16th, 2019.
