Wavin Annual Report 2010 | page 31Plan de Cuques,FranceBus lane keeps the town dry… and greenIt sounds contradictory – a bus lane keeping a town both dry and green. But in Plan de Cuques, a smalltown near the French city of Marseille that is exactly what is happening.Plan de Cuques wanted to fi nd a way to stop its streets being fl ooded when it rained – a fairly commonproblem in urban areas with mainly hard surfaces that do not allow excess water to soak into the groundnaturally. At the same time, Plan de Cuques aimed to keep the green areas it does have green in aneconomical and sustainable way – a problem when the average total rainfall in three months in thesummer adds up to less than two centimetres. This problem was solved with Intesio, Wavin’s watermanagement solution.The obvious answer is to store the rainwater and use it for irrigation. As rainwater needs no purifi cationbefore being used for irrigation it is an energy-saving, and therefore cost-saving option. But the onlyplace to put a large enough storage tank was under the bus lane, which made the project morecomplex. After conducting all the necessary surveys and drawing up the entire plan using its ‘Calculus’programme, Wavin created a buffer system comprising of a large number of Q-Bic infi ltration units andTegra inspection chambers.The system was easy to install, and to maintain thanks to its easy accessibility for regular (video)inspection and cleaning. It has a long life-cycle and all the plastic materials used in the system arerecyclable. And, of course, throughout the entire project from planning to installation Wavin’s expertswere on hand to provide the support to ensure the technically complex project ran smoothly.Wavin Tegra 1000The Wavin Tegra1000 is large enoughfor entry toinspection, cleaningand maintenance.Wavin Q-BicThe Wavin Q-Bicinfi ltration unit is fullymodular andinspectable.
