USERS’ PLATFORM Applications Composite potable water lines are gaining ground A 1.5 km long steel pipeline from the early seventies needed to be replaced in Unterröblingen (G) to ensure the potable water supply for the brown coal plant Romonta LTD as well as for all connected municipalities. The client opted for a composite solution. ince the line runs through an old industrial area with ecologically-damaged terrain, it was the client’s high concern to choose the right pipe material which would withstand highly aggressive soil and which would not allow any diffusion. Absolute leak tightness from inside and outside the pipeline is essential for clean and hygienic potable water. The water supplier Midewa (Middle Germany), who distributes potable water over a total network length of 4,900 km, sees it as their responsibility to provide both their private customers and middle-scale companies with a sufficient quantity of high-quality drinking water. HOBAS® CC-GRP pipe systems and their characteristics met the project’s requirements regarding the difficult terrain and the aggressive soils, as well as the enormous cost pressure that water supply utilities suffer from in Germany. S Fast construction The construction works for the 1.5 km long composite pipes started end of November 2005 and the first of the three construction phases was completed as early as May 2006. HOBAS® CC-GRP WaterLine® pipes produced by HOBAS Pipe Germany were delivered in a standard length of 6 m, with sealing caps on both ends to keep the inside clean and avoid the need for any additional disinfection. It should also be mentioned that the company produces the WaterLine® in an eye-catching blue colour to distinguish these pressure pipes certified for potable water from other product lines. Being both the contractor and the constructor, it is an advantage to Midewa that the construction can be executed with two pipe layers, a machinist and a labourer only, and as little gear as a wheel loader, an excavator and a plate vibrator. In terms of installation, a noteworthy advantage of the composite pipes is their low weight, which facilitates handling on site considerably. They can be easily More information For the past 50 years, the name HOBAS has been synonymous with centrifugally-cast (CC) GRP pipe systems. The company’s patented centrifugal casting process produces compact pipes with programmable characteristics, allowing individual solutions. moved in the narrow pipe trenches and are quickly joined by hand thanks to their push-to-fit Sealtight® couplings which are pre-mounted on one pipe end. Recognized advantages Flexibility for the customer in terms of the choice of materials is ensured through the compatibility of the pipe systems with cast iron pipes and fittings for example, which were also used in the project. HOBAS® CC-GRP pipe systems, which have been tested and approved by the water authorities of various countries such as Austria, Croatia, the Czech Republic, Germany, Norway, Romania, Spain, Switzerland, Turkey, the UK, the USA and Italy, have thus found their way into the Middle German potable water network as the first GRP pipe ever.
