- the people and
- the industry,Tourism, Agriculture, hydropower etc
OVERVIEW AND BACKGROUND OF LLWSS
- LLWSS devised to supply water to that area of Lesotho with 75% of population and most industry agricultural activity
- 2004 – the feasibility study of the Lesotho Lowlands Bulk Water Supply Scheme was done and divided the scheme into 8 water demand zone areas.
- 2008 – Lesotho Lowlands Water Supply Scheme detailed designs & procurement documents were completed with the design horizon of 2020 and 2035
- 2016 – Construction of the Metolong Dam to serve Zone 4 &5 was completed
- Downstream conveyance system to serve Maseru, Berea (Zone 4 ) and partial (Zone 5 in Mafeteng)
- Outstanding works are zones 1-3 and 6-8, some in part of 5
