Bigen Africa, one of South Africa's leading infrastructure development companies, has been appointed as consulting engineers for a ground-breaking housing project in Scottsdene, Kraaifontein, in the Western Cape, by the developer Calgro M3 Holdings. Bigen Africa will undertake the management and design of all civil engineering work required for this project, which follows government's new approach to developing integrated human settlements by actively involving private sector funders.
Th e Nelson Mandela Bay Municipality (NMBM) embarked on a large-scale water conservation and water demand management (WC/WDM) programme in 2009. The objective is to reduce non-revenue water (NRW) by 15% within ten years (nonrevenue water is the difference between 'system input volume' and 'billed authorised consumption'). Th e severity of the recent 2009 to 2011 drought in the Eastern Cape resulted in the municipality intensifying many of the WC/WDM interventions, allwith the view to reducing NRW and water wastage and improving the sustainability of water services. Since the drought broke and the NMBM lifted their emergency water restrictions, the focus of the Water Loss Programme has shifted, putting more emphasis on initiatives that reduce unbilled authorised consumption and apparent losses.
The catchment area of the De Bos Dam, which is the main water source for the Greater Hermanus Area, has experienced one of its most severe droughts in recent history, during a period stretching from September 2010 to April 2012. The dam content had dropped to below 20% of its full supply capacity by April 2012.
In early 2004 Jeffares & Green (J&G) was appointed by Aquamanzi Developments and Mhlathuze Water to prepare Department of Water Affairs and Forestry (DWAF) Version 3.3 Project Business Plans for the Enkanyezini Phase 2 and Kwangwanase Phase 3 Community Water Supply Schemes respectively. Both Aquamanzi Developments and Mhlathuze Water were acting as implementing agents for the uMkhanyakude District Municipality (UDM).
The question many local authorities have, is what the effect of proposed densification would be on the existing engineering infrastructure? The simple answer is that densification has an adverse effect on infrastructure, as the utilisation of capacity is increased. But the question remains how negative this is, as opposed to the benefits that densification could offer. The City of Cape Town recently commissioned a study to determine the effect of densification on water related services. Through GLS's involvement in the study, as well the company's other experiences of master planning of water and sewer networks throughout South Africa, some light can be shed on this issue
How does a Water Services Authority (WSA) serving a population of some 800 000 residents, comprising about 220 000 households in an area of nearly 37 000 square kilometres in 14 formal towns and several hundred rural villages, determine the magnitude (quantity and distribution) of the backlog in rural sanitation; then draft appropriate tenders (all within the necessary ecological, technical, financial and legal constraints and guidelines) and award contracts to deal with the backlog?
The new wastewater treatment plant currently under construction outside Swakopmund is that municipality's most ambitious engineering project to date. The urgent need for this facility to go live presented daunting challenges to all involved,including a tight deadline and very little margin for error.
The South African Institution of Civil Engineering (SAICE), together with the Water Information Network of South Africa (WIN-SA) and the Water Research Commission (WRC), is actively involved in a project aimed at growing good practice in municipal wastewater management.
Municipalities have to comply with numerous legislated requirements in terms of physical and management planning.These planning requirements are then linked with legislated budget and expenditure requirements. All these requirements are critical and are fully justified from a control and provincial/national reporting perspective. In many cases, however, councillors and officials see these requirements as just another box that has to be ticked to satisfy the 'authorities' and little regard is paid to the real benefit that can be obtained from properly integrating and utilising these planning elements.
This article proposes a practical planning process that utilises the legislated requirements, while at the same time encouraging a more structured internal approach within a municipality. This Integrated Planning Process will also assist municipalities to produce more effective budgets and to be in a position to effectively spend its money in a structured and planned manner.
