About Us

What is the Advanced Pumping Efficiency Program (APEP)?
The Advanced Pumping Efficiency Program (APEP or the "Program", formally known as the Agricultural Pumping Efficiency Program) is an educational and incentive rebate program developed to improve overall pumping plant efficiency and to encourage energy conservation.

How is the Program funded?
The Program is funded by Pacific Gas and Electric Company through 2012 using the Public Purpose Programs Fund under the auspices of the California Public Utilities Commission. A small portion of each ratepayer's bill goes to this Fund. This money is intended to fund research and development, education and demonstration, and direct rebate programs that improve energy efficiency and promote overall energy conservation in California.

Who developed and manages the program?
The Center for Irrigation Technology (CIT) developed and manages the Advanced Pumping Efficiency Program. CIT is dedicated to advancing water and energy management practices and efficient irrigation technology. Located on the campus of California State University, Fresno, CIT functions as an independent testing laboratory, applied research facility and educational resource to both the public and private sectors.

How long is the Program available?
The Program is currently funded through December 2012. The program has a limited budget and may be terminated or modified without notice. Check this website or call one of the Program offices for up-to-date imformation .

What does the Program offer?
The Advanced Pumping Efficiency Program is a comprehensive effort to improve energy efficiency in California's irrigated agriculture. The Program achieves these goals by:

  1. Helping to install and maintain high-efficiency irrigation pumping plants in the field.
  2. Helping to manage those pumping plants correctly.

The APEP offers:

1. Education

Educational seminars concerning pumping plant specifications and maintenance, crop water requirements, and water management are presented throughout the state. The education message has four components, all of which are covered in this book:

a. Know how to specify an efficient pump.
b. Know how to maintain an efficient pump.
c. Know how much water needs to be pumped.
d. Know how much water has been pumped.

2. Technical Assistance

Program personnel are available to help in locating pump efficiency testers, completing a pump retrofit/repair incentive rebate application form, or to answer general questions about pumping plant design and use. Please note that the Program does not offer site-specific engineering services. That is, we cannot help you design and install a specific pumping plant.

3. Subsidies for pump efficiency tests are paid.

Rebates for pump efficiency tests are paid directly to participating pump test companies. Tests are available for working, electric- or natural gas-powered agricultural or large turf water pumps. Note that tests are not available to fulfill requirements of any public or quasi-public agency or in relation to a real estate transaction. However, participants in the PG&E AG-ICE program are specifically eligible for all components of APEP.

4. Incentive for Pumping System Retrofits

Incentives are available to individuals for retrofit of eligible and working electric- or natural gas-powered water pumps. There are several important eligibility factors regarding project type and timing of the incentive application versus the completion of the project for incentives. You are encouraged to talk to a Program representative. Complete information is provided in the APEP Policies and Procedures Manual

What Resources are available?
The Advanced Pumping Efficiency Program has a variety of resources available at no charge.

1. Regional Offices and Toll-Free Assistance at (805)-547-1130

The Program maintains offices throughout the state and provides toll-free assistance.

  • Main Office
  • Central/Southern California
  • Northern California
  • Central Coast

2. Web Sites
The Program maintains on-line resources that can provide valuable information on water and energy savings.


The Program web site provides summaries of all program components, a calendar of upcoming events, application forms, phone numbers, contact information, and a knowledge base. Here you can type in a word or phrase and a list of technical papers will be presented that pertain to that word or phrase. For example, you may type in "irrigation efficiency." Several papers will be presented that define irrigation efficiency, tell how it can be measured in the field, and how you can improve your efficiency.


This interactive web site provides the tools to develop site-specific, seasonal irrigation schedules. The site also contains educational material and reference data on water and energy management including CIMIS crop water use data.

3. Seminars

APEP offers seminars throughout California. Most of these seminars come to you via the Mobile Education Centers. Others are provided at fixed sites. Dates and locations of upcoming events are listed on the web site or you can call one of the offices to find out when a seminar will be presented in your area. All seminars are free of charge.

On-Site Seminars with Mobile Education Centers (MEC)
The Program brings educational seminars to farmers in the field using two Mobile Education Centers. These are enclosed trailers with self-contained pumping plants. They are used to introduce the basic concepts of pump performance and how to specify and maintain an efficient pump. They travel around the state and are used to present educational seminars of various lengths and on different subjects.

Seminars at Pump Demonstration Facilities in Fresno and Chico
Demonstration and calibration facilities are located at California State University, Fresno and California State University, Chico. These facilities are located next to fields so they can be used to demonstrate irrigation efficiency concepts as well as pumping efficiency. Introduction

4. Written Materials
The Program distributes several types of written materials including a 60-page pamphlet containing the complete educational message and the Pumping Energy Calculator . Individual brochures are available providing summary discussions of pump efficiency, flow meters, irrigation planning, specifying an efficient pump and education. Call one of our offices to have materials mailed directly to you or visit our web site at www.pumpefficiency.org for downloadable PDF versions.

"Diesel Pumping Efficiency Program"

The Diesel Pumping Efficiency Program (DPEP) is an extension of the concepts employed by APEP but specifically addressing diesel-powered pumping plants in the San Joaquin Valley. DPEP was operated as a pilot-level effort with funding from two sources, 1) Valley CAN (a private grant foundation) and 2) Region 9 of the US EPA. Funding totals over $115,000 with the goals of:

  • Performing 62 pump efficiency tests
  • Incenting owners to retrofit 11 pumps.
  • Development of a "pump tester's kit" that will help pump testers throughout California to be able to test diesel-powered pumping plants as well as electric-powered pumps. This kit will include a parts list and instructions for construction of a fuel flow meter as well as software for databasing the measurements and calculation and preparing the test report.

As of January 30, 2006 the Program has performed 52 tests and accepted 14 applications for pump retrofits. Two of these retrofits have been completed and post-retrofit tests performed. The Program is on schedule and final reports will be issued as all retrofits and post-retrofit tests are completed.
