A first-of-its-kind study was commissioned by the Metolong Authority in Lesotho to research the potential impacts of climate change on the long-term yield of the proposed Metolong Dam. Experts from consulting firm Arcus GIBB, supported by consultants Jeffares & Green, who specialise in the fields of hydrology, water resources planning and the impacts of climate change on hydro-climatic hazards, looked at the possible effects of climate change on an infrastructure that will need to stand for at least the next 100 years.

A R92 million bulk pipeline stretching 5,7 km has been laid to boost the water supply from Pietermaritzburg to Durban by 1 024 litres per second. Umgeni Water, the bulk water provider, needed to improve the water supply to both eThekwini and Msunduzi Municipalities and commissioned Jeffares & Green to design a pipeline to boost the connection from the Midmar Water Treatment Works to World’s View Reservoir. The previous system supplied water at a rate of 130 Ml/d but the ultimate design called for a total of 330 Ml/d.

The topic of engineering service contributions is one with which most developers are already familiar. The legal and regulatory frameworks surrounding the amount of the contribution for a development, and the means of making it, are still very much in the developmental stages. Dr John Sampson, a civil engineer specialising in transport engineering, addressed a seminar held by the South African Institute of Valuers late last year, in order to try to shed some light on the process.

There has been quiet but active engagement to improve the water-supply situation in Lesotho.
South Africa’s awareness of water issues in Lesotho has been likened to a nodding acquaintance. Generally there is recognition of the essential water supplies received from the Lesotho Highlands Water Project but little appreciation of the fact that virtually none of this water is available for use in Lesotho itself. However Lesotho does benefit materially from hydropower generation and is almost completely self-sufficient in this regard. Royalties paid on the wate
