 Sandy water?

No problem for high-pressure hydro electric power stations with a Bieri desander.

Water intake for high-pressure hydro power plants requires effective desanding. Without a reliable desanding system wear on turbines, nozzle valves, control devices and pressure pipes incurs very high repairs. 
The BIERI desanding system can be adapted to all sizes of basins with inflow volumes between 1 m 3/sec to 150 m 3/sec. spread over several basins 
Swiss Sedimentation Technologies is an engineering company which develops and install complete vertical desanding systems for hydro electric power plants. SST produces and install  vertical desanding systems, based on the technology developed by Bieri, with hydro-mechanical elements and also makes revisions and refurbishment of existing installations and related hydro-mechanical components (such as rack cleaning machines, flushing gates)
