Construction of works on La Gogue Dam in Seychelles are now at 70%. The Public Utilities Corporation (PUC) said that three quarters of the work needed to raise Seychelles’ main reservoir by 6 metres was complete. The dam whose storage will increase by 600,000 cubic metres to 1.6 million cubic metres, is expected to be operational at the end of June 2021, six months behind schedule. Adverse weather conditions coupled with a series of protests by local truck owners have caused major delays.
Erna Victor, the officer responsible for the project at the PUC, said that the replacement of all the pipes, valves and fittings in the intake tower and tunnel have been completed. In order to increase the intake tower height by an additional 6 metres, the concrete top has been demolished and the existing footbridge has been removed. The contractor has also begun installing reinforcements and formwork for concrete casting. The oil filling and compaction work in preparation for the construction of the permanent road around the dam are well underway.
Renovation works of the La Gogue dam and the construction of the new treatment facility are being undertaken by Chinese contractor Sinohydro at a cost of US $13.6m funded by the African Development Bank (AfDB) and Seychelles’ government.
Local service providers
Victor also explained that since this was a PUC project, the contractor was encouraged to engage the services of local providers. In support of this recommendation, Sinohydro has employed the services of a local subcontractor as well as several other local service providers to carry out works related to the project,” explained Victor.
Once the dam becomes operational, work will shift to the second component of the project which is the construction of a new water treatment plant. The plant will have the capacity to treat 4,400 cubic metres of water per day. The La Gogue plant is expected to be completed in June 2021. It will be the fourth treatment plant after Hermitage, Le Niole and Cascade, distributing potable water to Mahe – the main island of the 115 islands archipelago in the western Indian Ocean.
