Plastic Buffer Basin in Belgium
It’s amazing what can be accomplished when a team of like-minded experts collaborate on a “first-of-its-kind” project. Wavin, alongside KRAH, Aquafin and PlaatserThermopol were commissioned by Besix Infra to produce and construct a huge buffer basin to collect and retain the rain water around the playground in the Villermontstraat — for the municipality of Kontich in Belgium. Made entirely of plastic pipes, the basin has the capacity to collect a massive 840,000 liters of water!
The challenge — rain water retention and collectionThe municipality of Kontich (in Belgium) needed a durable and dynamic solution to buffer the rain water around the playground in the Villermontstraat. The city needed a rainwater buffer to collect surplus water from the entire center area — to mitigate the challenge of heavy and long-term precipitation, so that excess rainwater can flow in a controlled manner to the water-sensitive area.
The solution — an example of how to future-proof a cityTwo words: plastic pipes. The municipality decided on a design concept to create a gigantic buffer basin, made out of plastic pipes. The water will be collected in plastic pipes with a diameter of 2.4 meters. They are laid out in a construction pit of 55 meters long, 18 meters wide and 5 meters deep. It is the first time in Belgium that a buffer basin with plastic pipes has ever been built! Together, the plastic tubes will have a total length of 200 meters.
In the Netherlands, the system is already being applied in a few places with a positive result. The big advantage of this type of buffering is that the tubes are watertight. This is important to keep the groundwater up to standard. In addition, the pipes are accessible without any problems by maintenance workers and inspectionWillem Schrooyen , Account Manager/Wavin Belgium
The team of expertsA project is only good as the sum of its parts. And for this challenging project, the team was impeccable. Rudy Van den Boogaert, the senior project engineer for PlaatserThermopol has worked with Wavin for decades. His group was responsible for pre-installation — providing materials and calculations — whilst Wavin was in charge of the construction and installation. It was a very smooth project with excellent collaboration. The team was proud of the fact that all expected delivery times were perfectly met — thanks to an exemplary collaboration.
I think Wavin is the most dynamic player in the field. They’re able to make themselves highly visual in the market. Also, the quality of the products is outstanding and the team is just more passionate and driven. The brand’s reputation in Belgium is undisputed and that’s a result of years of dedicated work. They bring value to the field!Rudy Van den Boogaert , Sr. Project Engineer/ PlaatserThermopol
Plastic pipes’ lifetime has already proven to be not less than 100 years, especially with pipes that are produced with only 100% virgin high end PE100 raw materials. Also, if you have electro fusion connections – this ensures that after the installation you have one big homogeneous unit and no risk of getting leakages from the connections (this happens quite often when the rubber seal connections has been used). Also with e-fusion You don't have the risk of tree roots growing into the pipeline (which happens quite often with concrete pipes).Rene Aguraiuja , Commercial Manager/Krah Pipes
Most importantly, the contractor for the project, Jeroen De Beleyr of Besix Infra, was happy with the results.
The logistics and technical implementation — together with all parties — were performed to everyone’s satisfaction. The construction of the basin is part of the full reconstruction of the Edegemsesteenweg. The work began in October of 2017 and should be concluded by September of 2018.
We asked Wavin for a full-service solution for this exceptional project -- from delivering the materials to welding the pipes -- all within a tight timeframe. The materials were of outstanding quality and the collaboration with all parties went smoothly. We are pleased with the results.Jeroen De Beleyr , Assistent Projectleider Wegen & Riolering bij BESIX Infra
