Back Flush - Intake
Back Flush - Intake
(OP)
Might be an easy one.
Anyone has more information about a system for back flushing sediment in a a water intake ?
The intake is for a fire protection system.
A pipe is delivering water by gravity to the water pump pit and is approximately 100 feet long with a diameter of 36 inches. The intake has a 4'x 4' box with bars to prevent coarser material and debris to enter the pipe. But the finer material is still entering and reducing the cross section area of the pipe.

Not for drinking water.

If river currents are pushing sand into the intake box, then you need to move the box out of the river currents to prevent that. Making the box bigger than 4x4 might help also.

Pumping water back in a 36'' corrugated steel pipe flowing in the opposite direction seems... un-realistic.
