To improve the drinking water supply, a transmission pipeline for treated drinking water was laid in Aspach – partly without sand bedding using open-cut construction, and partly using the trenchless drilling method. To prevent water losses and enable quick reaction in the event of damage, the continuously monitorable SLM® DCS pipe system was deployed.
Water Supply Concept for the Rems-Murr District
Several municipalities, based on a comprehensive supply concept and in cooperation with NOW (Water Supply Association of Northeast Württemberg), have decided to implement a joint project to improve the drinking water supply in the northern Rems-Murr District. In addition to NOW, the project sponsors are the municipalities of Oppenweiler, Leutenbach, Allmersbach im Tal, Aspach, Burgstetten, and Stadtwerke Backnang. The own water resources of the participating partners are to be collected at the NOW Murrtal waterworks via raw water pipelines, treated, and then distributed back to the municipalities via treated water pipelines. The concept is supported by funding from the state of Baden-Württemberg.
Within the municipality of Aspach, the pipeline route begins north of the municipality of Rietenau at the elevated reservoir and continues north of Allmersbach a. Weinberg to the Einöd pumping station. The route length of the transmission pipelines measures 4.5 km. The total length of pipelines to be laid for raw water & treated water is 9.5 km. Along the route, the water pipelines are laid across farm tracks, through scattered orchards, over agricultural land, and repeatedly through vineyards, which presented a challenge for construction logistics due to the very confined conditions in the vineyards. Sand bedding was omitted. The construction work is largely carried out using open-cut construction. In two sections, the pipelines were laid using the trenchless drilling method.
A challenge with pipelines of this length is that potential leaks, when detected by traditional differential measurement between inlet and outlet meters, may only be noticed very late and merely indicate possible damage to the pipeline – thus leaving room for interpretation and providing no reliable information about actual pipeline damage. Furthermore, a leak is often very difficult to locate and repair, requiring significant time and effort.
To prevent water losses and enable quick reaction in the event of damage, the Water Supply Association of Northeast Württemberg, in coordination with the municipality of Aspach, decided to implement all pipelines in construction section 3.2.2 with the SLM® DCS pipe system. “The system offers the possibility to continuously monitor the pipeline. In the event of damage, the monitoring unit reports in real-time to the control center at NOW headquarters in Crailsheim, and we can precisely locate and repair the damage to within one meter,” says Marco Düring from the Water Supply Association of Northeast Württemberg.
