AWWA Pump Selection and Troubleshooting Field Guide
AWWA Pump Selection and Troubleshooting Field Guide A water system consists of many components, including a power supply, electrical wiring, switchgear, motor starters, the pumps themselves, a piping network or distribution system to deliver the water, storage reservoirs, and system controls. For these reasons, pumps evaluated according to the needs of the system. All the components must be sized and selected properly for the system to operate correctly.
Once a pump is operating correctly, it should continue to do so if it maintained properly and the system conditions remain the same. However, the available horsepower may limit the operating range of a pump. For example, changes in the demand of the system may require an increase in horsepower, or even a new pump.
Calculations should be kept on site to allow a quick review of the sizing of a pump and motor. If there are changes, or if a pump is
not operating properly, the sizing criteria can quickly reviewed for compliance

Pumps are usually the most expensive part of a water system to operate. Even so, they are easy to neglect when they are operating
properly or seem to be. Pumps can also be very expensive to repair or replace after a failure. Such repairs can be time consuming and take staff away from other important duties. The author is aware of one facility where the water storage in the system was nearly depleted while an essential pump was being replaced. No fire flow capacity was available during that time as well
