Irrigation / CSV for irrigation pumping from somewhat dirty pond water

« on: September 24, 2013, 03:57:45 PM »

I am installing an irrigation system pumping from a pond reservoir. Water is drained from the pond by gravity to a 2 HP irrigation pump and then out to multiple turf and landscape irrigation zones.

The water is also used to supply hose outlets for non automated watering and other applications. There is a pressure tank and a pressure switch which starts the pump.

The pond is refilled from a canal intermittently. The water in the pond has intermittent algae blooms, particulate from plants that grow in it seasonally, also some sediment. It is screened prior to entering the pump but some debris gets in, not a lot. After the pump, there is a disc filter which effectively removes all particles and debris.

I would like to add a CSV to the system. As I understand it, a CSV will not work if installed after the disc filter, and the only place to add it would be directly after the pump, where there would be the potential that some debris/particles would enter it.

Which, if any CSVs would work in this application? Do any of the CSVs have a built in filter or screen for this purpose? Otherwise, what would be the best way to install a CSV in this setup?
