Abstract
A screen intake apparatus for a water intake system uses a cleaning system to clean one or more screen intakes. To clean debris from a screen, pipes in the interior of the screen receive pumped liquid (e.g., water or incompressible liquid) from a pump. Outlets, such as apertures or nozzles, on the pipes then direct the pumped liquid into the interior of the screen. One or more valves can vary, agitate, or pulse the flow of pumped fluid and/or can selectively deliver the pumped liquid to the pipes to remove collected debris from the exterior of the screen. A heater of the system can also heat the pumped liquid for delivery to the pipes to remove or prevent ice formation on the screen.
