Business and training: Mike’s message 41 Doing the right thing at the right time By Mike Muller Well, at least there has been some rain in Cape Town, although it is far too early to tell what level of restrictions Capetonians will have to endure in the coming summer. My contribution to saving water in South Africa was to spend a few weeks in Europe. But, as luck would have it, I ended up having to deal with a small plumbing problem in the flat where I was staying. What the experience of both Cape Town and South London has reminded me is how important it is to do the right thing at the right time, whether it involves household plumbing or supplying a city. As a professional engineer and an academic with a mandate to enquire, I have continued to probe and understand what happened in Cape Town. A good record exists of the process since 2007 when the Department of Water and Sanitation published its ‘reconciliation strategy’ for what it calls the Western Cape Water Supply System (WCWSS). The WCWSS is the set of rivers, six dams, tunnels, and pipelines that serve not just the city of Cape Town, but also the regions from Saldanha all the way through to Swellendam. The story is simple — and this comes from the minutes of the meetings. In 2007, the planners told the city and national minister that once the Berg River Dam was complete, new infrastructure would be needed by around 2015 to supply the growing population and economy. But, Cape Town politicians said they would encourage water saving and would not need anything before 2022. Then, a succession of national ministers had other things on their mind. By 2015, with a drought underway, Cape Town finally realised that they had a problem. Yet, by the time restrictions were introduced, the dams were less than half full — not a good place to start. www.plumbingafrica.co.za So what about my flat’s plumbing? It was simple. An antiquated toilet syphon had effectively rotted away and needed to be replaced. However, the six-storey building, constructed in the 1950s, had no stopcock for any of the 60 individual flats, just one for the entire building. The plumber had to excavate into the wall to locate the pipe so that he could freeze it shut, install an isolation valve, and then fix the syphon. In both cases, the problem was simple. If the city authorities had simply taken the professional advice they were given, they could have avoided the current mess. Just why they chose to second-guess their advisors is another matter. Reluctance to take advice from a department run by another party was one factor. Environmental lobbyists, who always (correctly) preach that we must consider whether water use can be reduced before we build infrastructure to increase supply, was another. Meanwhile, over in London, a lot of post-war rebuilding was going on in the 1950s and the authorities were probably keen to save costs. Local councils could override their own bylaws to do that. But, in both cases, they could have avoided a great deal of unnecessary aggravation if they had just done the right thing in the first place and listened to their professional advisors.
