future’: ‘Living within the carrying capacity of our planet’. More than 60 reviewed papers will be presented at the conference. As this edition of IMIESA is a water-focussed one, we have made sure that there is plenty of informative and reliable information within our water and wastewater feature. We publish a paper titled ‘Designing an innovative way to support water service authorities’, in which the authors discuss municipalities that are resource poor in terms of human capacity. In addition, Tony Stone has written an ‘Insight’ article on South Africa’s reliance on dams for its fresh water requirements. He highlights that, according to the World Commission on Dams Report, South Africa, with 539 major dams and approximately 4 000 dams in total, is the 11th most dammed country in the world. It is also the seventh in size in water supply dams and ninth in size in irrigation dams. The article also poses a seemingly impossible scenario: a search on Google lists 3 180 000 articles about future wars between nations being fought over water. South Africa, one of the 30 most arid countries in the world, could well become a warmonger.

COMMENT
PRESIDENT'S COMMENT
What are a municipality’s main functions? In my comment in the July issue, I said that we need to work together to find a proactive, innovative solution that could solve two major national problems, namely poor infrastructure asset management and large-scale unemployment. With this in mind, it is worth taking another look at our objectives in the IMESA constitution.
T
he Auditor-General’s recently released report on the local government audit outcomes for 2009/10 contains some depressing findings: only the following seven municipalities received clean audits (with no adverse findings): • Mpumalanga: Ehlazini, Steve Tshwete and Victor Khanye Municipalities • Gauteng: Metsweding District Municipality • Northern Cape: Frances Baard District Municipality • Limpopo: Fetakgomo Local Municipality • Western Cape: City of Cape Town. Looking at our constitution again, it clearly calls upon us to promote service delivery and the financial well-being of our municipalities. Cities, in particular, are seen as crucial economic agents as, when they are financially healthy, they can become the catalysts for efficient delivery of services and employment, which in turn promote stability and general prosperity. When they are poorly managed, however, they induce general mistrust on the part of the public, which can and has manifested itself in service delivery protests. A recent Institute for Democracy in South Africa (IDASA) survey, based on the views of persons in 21 municipalities, found that only a paltry one in ten citizens is satisfied with the quality of service delivery provided by his or her municipal council (it was four in ten in 2006). These findings are worrying in that it is stated that a local government crisis in South Africa is deepening and starting to become a systemic structural problem that seems likely to become more embedded in our system of local government for as long as the governance issues raised in the survey persist. The
survey’s depressing inference is that local government is widely considered by communities to have deteriorated in both service delivery and governance, which will inevitably lead to a continuation and intensification of social instability and protest. Looking back to 2010, South Africans could proudly claim to have embarked on a journey to build what we believed were the best stadiums in the world in which we hosted, almost flawlessly, the world’s greatest sporting spectacle, the Olympics aside. Every single person who contributed to these great projects made us very proud, and indeed the entire country felt a degree of involvement,
outside the box and seek to understand what it is that we as engineers need to do to take our wonderful country to the next level. Possible ways to assist service delivery were discussed at IMESA’s strategic planning meeting held in Johannesburg in January 2011. Vital to this was finding ways to improve supply chain management (SCM) and infrastructure management. For as long as processes and monitoring are focused purely on compliance, and not on practical ways to improve service delivery, we can expect service delivery protests to continue.
We need to retain the mindset which enabled the successes of 2010 and show that we are truly capable of repeating that success ownership even, in this massive achievement. While the time for celebration of that effort has now past, we need to retain the mindset which enabled the successes of 2010 and show through our words and deeds that we as a nation are truly capable of repeating that success. Obviously, there have been a lot of downs recently, but we will survive the current storms better than would otherwise have been the case, thanks to the lessons learnt during the World Cup. Just as municipal engineers were essential to the World Cup effort, so they will be vital to the future well-being of South Africa, and I appeal to all municipal engineers to step Jannie Pietersen, president of IMESA

COVER STORY
INNOVATIVE TECHNOLOGY FOCUSED ON RESPECTING THE ENVIRONMENT
Latest mobility concepts from MBSA to be showcased Mercedes-Benz South Africa (MBSA) will have an exciting and dominant presence at the Johannesburg International Motor Show in October, where it will showcase high-performance state-of the-art trucks, vans and buses.
A
s a leader in several vehicle market segments, and as a local manufacturer for 63 years, MBSA will continue to give the South African motoring public an array of world-class mobility options. It will entice visitors with its technologically advanced vehicles; innovative finance, insurance and fleet options; as well as its service and affordable parts supply solutions. Following their claim of ‘inventor of the automobile’ 125 years ago, the company will demonstrate its commitment to vehicle performance, combined with cleaner technology that is kinder to the environment, whilst simultaneously offering a wide motoring audience vehicles suited to each individual’s needs. The company’s brand displays will be integrated into consolidated show stands for both passenger cars and commercial vehicles. The MBSA stands will again be the largest since the inception of the local forerunner exhibition, Auto Africa, in 1998.
The finest cars of impeccable quality have been carefully selected to ensure that each model is offered to the public in a manner designed to demonstrate its remarkable attributes. The company plans to substantiate its leadership in keeping the ‘engines of the economy’ running on multiple commercial vehicle wheels, as well as in the private and public transport sectors. To whet visitors’ appetite, here is a peek into what will be on display: MBSA commercial vehicles exhibition in Hall 5: The MBSA commercial vehicles stable (inclusive of trucks, vans and buses) makes a truly bold statement at the Johannesburg Motor Show this year. In addition to the German engineering of the Mercedes-Benz models, the company also showcases the best of its classleading American and Japanese marques. • The ever-popular FUSO from Japan will have three models on display – a must-see is the

latest (and greenest) addition to the family, the Fuso Canter Eco Hybrid. Of American origin, the Freightliner Argosy range will show the serious visitor what the powerful Detroit Diesel engines can do for their business. Trucks can also be glamorous! Making a real splash at the entrance to the truck show at Hall 5 is a highly-polished, chromefinished Western Star model. Leading the Mercedes-Benz commercial vehicle exhibition will be its flagship Actros range, represented by two models. The first is an Actros Euro 5 BlueTEC, demonstrating that ‘the new green is BLUE’. The second is the Actros Special Edition, which comes with a host of fuel efficiency measures and safety systems – making the world’s safest truck even safer. The new Axor 6x4 is tough and can endure the harshest of conditions. No terrain or operating conditions are too rugged for this vehicle – a solid truck that can endure the toughest of environments. Also at the stand is a firm favourite in South Africa – the UNIMOG. This iconic brand has a rich and powerful heritage, having recently celebrated its 60th anniversary. An ‘environmental angel’ in the form of a Mercedes-Benz Econic NGT (natural gas technology) will ‘visit’ the truck stand. This advanced, environmentally-friendly, lowfloor transport vehicle is successfully used for municipal and short-radius distribution applications internationally, which explains why it dominates the inner-city mobility vehicle system sector in Europe and some South American markets.

This vehicle has made strong inroads into the transport and logistics sectors with its impressive strength and performance. • Continuing the focus on ‘clean technology’, the Viano FUN with the latest BlueEFFICIENCY technology feature – the ECO start/stop system has exemplary functionality, as well as offering spontaneity. It has a highly flexible variable system for seven-passenger seating configurations. • Sprinter displays its versatility in the shape of a mobile office. Standard safety features, such as the ADAPTIVE ESP (electronic stability control), ensure sensitivity and precision in critical driving situations. MBSA bus and coach exhibition in Hall 5: ‘Rea tsamaya – We are going!’ This is the mantra of the Mercedes-Benz bus and coach team who will exhibit the Multego semi-luxury coach, together with the OF1730 commuter bus, specifically designed to meet South Africa’s tough road conditions. These models play an integral part in providing world-class transport services in both the public and private sectors.

IMESA
Project and business management In accepting the challenges of engineering in Southern Africa, IMESA has restructured some of its executive council portfolios. One of the new technical portfolios is the Project and Business Management Portfolio. By Johan Basson, IMESA technical director
S
ome old portfolios were done away with and new ones created at the 2010 conference. This particular portfolio gives IMESA the opportunity to focus attention on some technical matters outside of the traditional technical working groups on water and wastewater, roads and storm water, computers, etc. and includes national priorities such as job creation, asset management and project and business management. In thinking of what to focus on in the Project and Business Management Portfolio, it became clear that, besides the conventional technical skills of management and running projects, IMESA should also look at the wider environment and the issues we are facing. Although this will obviously be too much for our limited voluntary members to deal with, we are becoming involved with the priority issues placed on our table, so to speak, by members and other participants in the municipal environment. This includes, among others, the challenges with service delivery, procurement, asset management and job creation. Through consultation with different role players, IMESA is trying to find new solutions and best practices to inform and assist our members and the municipal engineering environment.
• Promote and support the interests of infrastructure engineering professionals and the engineering fraternity involved. • Operate over a broad infrastructure engineering membership base to increase individual membership and affiliation. • Seek local and international partnerships and recognition and market itself among broad target audiences to improve awareness levels, its image and reputation. • Promote and exchange views and ideas on all aspects of infrastructure engineering, whether among engineers in the infrastructure engineering environment or others associated with, or having an interest in, its field of operation. • Develop knowledge products and services to support members in their profession. • Grow the revenue base and source funding for development and research. • Develop strategic partnerships with government, semi-government and academic, research and other institutions to the benefit of the institute, its members and the profession in general. I believe we should always ask ourselves what our ultimate goal in government is, meaning that we should keep our goals in mind in discussing how, when, what and by which means
Common objectives Before focusing on some of the issues, we need to look at the common objectives I believe we should share in our discussions. When considering the objectives of the institute listed below, it becomes clearer how IMESA should interact with its members, the government, engineering and the social and economic environment, in order to: • Promote the knowledge, art, science and practice of infrastructure engineering in all its aspects.
We are sometimes too closely focused on short-term successes, with a maximum of three to five years' vision

we support and do whatever is needed to achieve these goals. This is probably summarised in serving the people by providing, maintaining and managing services and a healthy, sustainable economic and social environment, or as IMESA president Jannie Pietersen sometimes states, it is about services delivery, asset management and good governance.
Strategic planning The environments we operate in and do our projects and conduct our business within are filled with many different role players and this surely demands management and coordinating. Sometimes municipal engineers feel frustrated by other sectors losing focus or chasing other priorities by not understanding this bigger picture. To some it feels like some of these actions, rules and programmes are making it even harder for municipal engineers to fulfil their functions properly. We are sometimes too closely focused on short-term success, with a maximum of three to five years’ vision. This, together with five-year terms, does not give enough support to proper longterm planning. Yearly performance evaluations with the emphasis, for example, on percentage spending as main criteria should play a part, but seen in the context of longer-term sustainability it is not necessarily a criterion, as it could be that everyone gets short-term
performance bonuses, clean audits, etc. but meanwhile there is raw sewer running into a river or there are people remaining without healthy conditions and clean water. The lack of technically skilled professionals in the top two to three levels of municipalities and other spheres of government limits the role of engineers, who are principally trained
not only to find short-term answers and solutions, but are by nature also future-planning orientated to play a significant part in providing strategic vision to their employers. IMESA tries to promote the notion of ‘The customer is the next process’ in aligning the different parts of the municipal sectors to keep the public customer in mind in all our different projects and daily functions. Interaction IMESA can play more of an important role in trying to get the engineering perspective across within the government. We have limited time and resources in this country and especially in local government, and therefore cannot afford not to be successful and passionate in trying to work towards achieving the common goals of service delivery, asset management and good governance. Some of the actions IMESA is currently taking in playing pivotal roles in achieving our objectives are in running our business as municipal engineers. This includes getting involved in intergovernmental consultations with other role players such as the South African Local Government Association, the Construction Education and Training Authority’s treasury, the Development Bank of Southern Africa and various national and provincial departments. Procurement One of the dialogues that IMESA is required to participate in is around the issues involved with service delivery and procurement. With changing regulations, legal interpretations and the continued quest to quell corruption, municipal engineering is being pressured into finding new methods to provide and maintain services on time, to acceptable quality and sustainable standards. The evaluation of service providers and contracts with life cycle costs, sustainability, maintenance and operational risks of failure, technical and social acceptance and value for money are currently proving to be extremely difficult. Continued consultation with all role players is required for better understanding, changing perceptions and finding new solutions. IMESA will have to be part and parcel of this consultation and training process on best practices.
Kerbs Dry-casting means no exposed aggregate or blowholes on the surface of our kerbs.
The only SABS-approved dry-cast kerb in SA. At Bosun, our approach to resolving engineering challenges has always been to simplify and innovate.
Asset management IMESA has also embarked on providing a service to municipalities through IMESA’s Infrastructure Management System (IIMS) – an initiative to assist municipalities with GRAP 17 compliance and the management of their infrastructure assets. Free IIMS asset management software is provided to municipalities to assist with the prioritising of infrastructure maintenance, development of asset maintenance budgets and many other aspects of infrastructure asset management. IMESA is currently involved in a number of municipalities in the Free State with the IIMS, and is also becoming more involved in the training of municipal staff and others in asset management throughout the country. A project and business management focus gives IMESA the opportunity to get involved in the wider environment that affects our daily operations, project cycles and the business environment we are operating in.
That’s why we’ve taken the manufacturing of kerbs further with our revolutionary dry-casting process. This allows us to compact the kerb, making a stronger, more durable end product. And, making kerbs the Bosun way is kinder to the environment. No acids and chemicals are needed as mould release agents. Another great reason to specify Bosun kerbs on your next civil engineering project. Visit www.bosun.co.za for even more ideas.
