Screens are essential for the protection of pumps and treatment works from reservoir debris, Bar screens are located at the paldang 2 intake pump station to prevent entrance of large objects. Clogging is the principal problem associated with fixed screen. therefore fixed screen must be checked and cleaned periodically. There were many problems in fixed screen such as underwater work. clogging. c1caning manually etc. In this study, We developed fixed screen cleaner in order to deal with these problems. The field tests were carried out for the fixed screen. We obtained good results.

Intake pump for waterworks is badly damaged by a small amount of cavitation because of variable water quality and severe operation conditions. In general, the required NPSH for reduced cavitation can be provided by inlet condition, supply air, change pump and inducer. But once the pump has been built and installed there is little that can be done to reduce cavitation damage. In this study, we analysed the cavitation of paldang intake pump and intended to avoid the same phenomena.
