SediCon enables environment-friendly sediment removal from reservoirs

- SediCon Dredge is a gravity-powered hydrosuction system for removing sediment from reservoirs. It uses available water head to move water and sediment through discharge outlets routed through or over a dam or spillway. Its jetting and unrestricted-flow arrangement is intended to handle cohesive clay, organic matter, sand and stones. The company says the user can choose the discharge time and location; it reports completed designs for depths down to 180 metres.
- The page says few moving parts keep operating and maintenance costs low. SediCon reports operational availability up to 99% over long periods. It says water level and quality are unaffected while dredging, allowing power generation to continue. Gravity drive avoids diesel use; compared with diesel dredging, the company says emissions are nearly zero and diesel contamination is avoided.
- The article contrasts its approach with bottom sluices, which may remove too little sediment, and diesel dredging, which can be costly and carbon-intensive. It frames sediment accumulation as reducing reservoir capacity, energy output and discharge capability while increasing wear and load on dams.
- Market text repeats older estimates: 60% growth in global power demand by 2040, 125 GW of hydropower capacity growth by 2023, and roughly 10,000 TWh/year of unused hydropower potential. The 2023 projection has passed; these figures are article-era estimates. SediCon says it was founded in 1999 and had installed sediment-management solutions in 20 countries. Related products include the Desander Dredge, Sluicer and Gravel Excluder.
