Delivering On Bulk Water Supply Projects


 

In many rural areas, households have to walk 200 metres just to get water. This situation has led to the Fort Brown bulk water supply project, an initiative that is aimed at the supply of bulk water to rural areas. “The project was requested by the Makana Municipality in Grahamstown and is currently in its commission phase,” says Kwezi Mpuhlu, one of the partners at MBSA Consulting Engineers.
 

According to Kwezi, the project is extremely labour intensive and is aimed at assisting the community with job creation. “We used unskilled workers to help with the water supply and appointed a consultant to supervise the process. This arrangement turned out to be a win-win situation as community members were taught how to provide water for themselves and acquired much needed income and invaluable skills in the process,” says Kwezi, adding that the feasibility test was conducted in January 2004.

Due to its sizable scope, the project was divided into two phases. The first half of the assignment entailed the extraction of water from the river to portable purification plants. Water was then stored in containers and filtered through a chemical process. The total cost for phase is R1 million. It started in September 2004 and has since been completed in February 2005.
 

 



Besides the usual project challenges, environmentalists proved to be yet another barrier. The team therefore had to submit a scoping report in order to adhere to requirements. “Some of the farmers fenced off a portion of their land, which meant that we had to avoid this area completely. This led to numerous public participation and site meetings and we were watched very closely,” says Kwezi.

The idea in phase two of the project is to build an agri village. Agri villages are smallholdings where community members are allocated small plots of land for grazing and services. The cost for phase two is estimated at R15 million and is likely to be completed in 2007.

Most of MBSA’s projects are water and road related. “We tend to concentrate on rural access roads, rural water schemes and bulk water supplies. In all cases we make use of Civil Designer and AllyCAD to fulfil our design needs. We are also in the process of employing more students so that we can teach them how to use the program and thereby create additional backup staff for projects.”

Another venture that MBSA is currently working on is the Hota-Mbewula bulk water scheme project. “We have just completed the preliminary designs for the water scheme and submitted these to the client. The aim of the project is to make water accessible to rural areas, which means a greater commitment towards spring water protection. This activity entails the collection of water from mountain springs and the construction of water purification reservoirs for reticulation purposes. The process requires no power as the entire procedure makes use of gravity. Once we have sized the pipes, we make use of AllyCAD to complete the design.”

The bulk water scheme project was requested by the Chris Hane Dristrict Municipality and is estimated at a cost of R5 million. “Our appointment during this initiative involved the preparation of a business plan in accordance with DWAF requirements. This plan was presented electronically via an online web-based system. Other responsibilities on the project included a feasibility study, the scoping report, the construction license application as well as some water availability testing. We submitted the business plan in March 2004 and have since completed the project designs,” explains Kwezi, adding that the construction phase is due to happen in July 2005.
