Water & Soil Water Quality Improvement / Water Management Technology Water Supply / Sewerage

Others Hardware / Technology Environmental Construction Technique

This is a construction method used for cleaning pressure feed pipes.
Dirt inside the pumping pipe can be removed with a special ice sherbet, and the dirt can be discharged out of the pipe.
