Chico, CA 95973 Dear Dave Woods: Enclosed are the results of your pump test. The results are based on conditions during the time of the test. If these conditions vary from the normal operation of your pump, the results shown may not describe the pump's normal performance. Some of the factors, which influence pump performance, are: - Changes in discharge pressures - Changes in water table level and well yield - Pump wear - Proper pump design for application We offer the following services to help our customers save time and money. Pump testing, irrigation system analysis, irrigation water management, and electric rate management. Visit our website at www.powerhydrodynamics.com for more information or to use our water cost calculator. Please feel free to call 209-527-2908 if you have questions about this test or on the other services that Power Services has to offer.

Chico, CA 95973 This letter is to confirm the information we gathered during the Pump Test that was performed on July 31, 2019 for the Fire Hydrants located on Red Fox Ct. in Chico, CA. On this day we measured a sustained flow of 490 GPM at 20 PSI for 60 minutes on the nearest hydrant and a flow of 417 GPM at 24 PSI for 30 minutes on the farthest hydrant. We used equipment that is accurate +/- .02% for flow measurement and +/- .005% for pressure measurement. The methodology used to test this pump was that of the California Association of Pump Test Professionals and is recognized to be accurate by the U.S. Department of Energy, the Hydraulic Institute, the California Energy Commission, Pacific Gas and Electric, Southern California Edison and the California Public Utilities Commission. This information should fulfill the requirements imposed upon you by the inspecting Fire District. Should the Fire Marshall from your District have further questions, please have them contact me directly in my office (209) 527-2908 or (800) 808-9283.
