HHO Africa ( is a well established and broad based consulting civil engineering company, recognised for their excellence in planning and design through numerous awards for technical excellence, innovative and environmental sensitivity.

This project formed part of the greater Umtata periurban phase 1 water supply project. Conceived in 1994, the Lower Corana project supplies 24000 people with a basic water supply. The project also had to meet the government criteria of ownership, sustainability and development. A large emphasis was placed on training the local communities. The training ensured community structures were put in place to engage with the technical stakeholders, who manage the operation and maintenance of the reticulation and plan for future extensions to the schemes.

The project was awarded the best SAICE (Amatola Branch) community based project for 2002.

Lower Corana (known as phase 1e) was designed by HHO Africa's water division. The scope of works was presented to and approved by the communities. The community structures were also used to identify labour in the various villages, identify local sub contractors, negotiate contracts on behalf of labour and sub contractors. In addition to these tasks, the community structures also provided discipline and a forum to solve any problems on site.

The scheme was designed to transfer 825m of purified water daily from the King Sabata Dalenyebo local municipality to eight villages situated along the R61 and T30 roads.
A Community Based & Labour Intensive Construction Project

A system of bulk pipelines, booster pump stations and reservoirs were used to ensure each village received a basic water supply, meeting the design criterion of 25l/capita/day at 200m walking distance.

In addition to the above, the following was also achieved:
  • Work for 964 local community members
  • R1.5 million was spent on labour and community participation
  • Local community members received accredited training in pipe laying and contracting business skills
  • Installation of approximately 32km of bulk and 52km of reticulation pipelines using community labour
The client for this project was the O.R. Tambo District Municipality.
