Idreco (International Dredger Constructions) of the Netherlands has designed, built and installed its second dredger at the Inga Dam in The Democratic Republic of Congo.

The ISD 600 has a digging depth of 30m, and the dredge has a mixture production and solids production of approximately of 5,000m3/hr and 1,500m3/hr using an IDRECO designed IDP 600 pump.

The 1775MW Inga dam is operated by Société Nationale d’Électricité (SNEL). Sedimentation build up at the dam has reduced water capacity, affecting energy production at the project. By removing the sediment deposit with this high volume dredging technology, SNEL, after 2-3 years, will resolve their reduced electrical generation problem and depending on the dredging production hours the remainder of the dam area can be cleaned together with the existing Idreco dredger type ISD 550, with a 20m digging depth, said the company.
