3 Treaty signed on 24 Oct 1986 Phase II Agreement signed on 11 August 2011

4 WHAT IS THE LHWP ? Bi-national interbasin water transfer - ultimate delivery 70 m 3 /s 5 Phases - 30 year Implementation - LHWC, LHDA & TCTA One of largest engineering projects Worth $ 8 billion

5 WHY THE LHWP ? Augmentation for Vaal System in RSA Millions people without water Cheaper alternative source Good quality water Opportunity for regional development Hydro-electricity for Lesotho

6 Project governance LESOTHO HIGHLANDS WATER COMMISSION
