The Lesotho Highlands Water Project (LHWP) managed by Lesotho Highlands Development Authority (LHDA) is a multi-phased project to provide water to the Gauteng region of South Africa and to generate hydroelectricity for Lesotho. It was established by the 1986 Treaty signed by the governments of the Kingdom of Lesotho and the Republic of South Africa. The project entails harnessing the waters of the Senqu/Orange River in the Lesotho highlands through the construction of a series of dams for the mutual benefit of the two countries. Phase I of the project was completed in 2003 and inaugurated in 2004 and Phase II is currently underway.
LHDA required an Enterprise Asset Management solution capable of managing the entire asset infrastructure from civil, water and electricity assets, distributed over remote sites at Muela, Katse and Muhale Dams, while operating over an unstable network. The solution had to be able to provide each site with the required business functionality of asset, work, inventory and procurement management, while integrating to a centralised financial system in Maseru. As with most remote African sites, network connectivity remains a huge challenge. The three remaining sites had to deal with the challenge of being able to continue with their maintenance and procurement operations, while unable to connect to the server installed at Maseru.
LHDA selected IBM Maximo as Enterprise Asset Management system which was initially launched at Katse Dam. Vetasi was contracted to roll out IBM Maximo to all sites and integrate to the centralised financial system.
The Vetasi Approach
Vetasi proposed a data replication concept based on the latest release of IBM Maximo that would enable remote end users to have a permanent connection to Maximo, even while network communication has been lost with the main server.
The concept utilised a local installation of Maximo at each site, to ensure business process continuity for when the networks are down. Data is then replicated to a centralised server in Maseru where the financial system resides. All site-specific information from the centralised sever is then replicated back to the sites. The solution provides seamless business operations on site independent of network stability.
