Fernwasserversorgung Oberfranken modernises Scheßlitzer Ast
The utility company Fernwasserversorgung Oberfranken based in Kronach (FWO) is optimising their entire system in its service area in order to ensure that the water supply in the Bamberg-Kulmbach region will continue to be secure and of high quality in the future. Increasing the transport capacity of the Scheßlitzer Ast, a long-distance water supply pipeline, and modernising the existing pumping stations and elevated tanks is part of those efforts. GAUFF Engineering was commissioned by FWO in providing the required engineering services.
The Scheßlitzer Ast has been in operation for more than 35 years. Modernisation and replacement measures as well as an adaptation of the transport capacity to accommodate for increased water consumption by the customers are needed.
Possibilities for expanding the transport capacity were examined and the existing conditions were compared to the maximum possible transport capacity of the transportation system in a comprehensive hydraulic calculation study conducted in September of 2016. Key data for the modernisation were established on the basis of this study. The water supply system that was examined encompasses around 48.8 km of transmission pipelines with nominal widths of DN 200 to DN 400 as well as four elevated tanks and two pumping stations.
In the course of modernising process, pipes as well as mechanical and electrical engineering component in the existing structures will be replaced. In addition a completely new elevated tank and pumping station will be constructed. Conversion work to replace electrical engineering system components in the Drosendorf pumping station and elevated tank began in April of 2017.
Supplying drinking water to the connected customers with no interruptions has to be ensured throughout the construction phase. Therefore, a significant challenge for the utility company, the construction company and our engineers is that all modernisation work has to be carried out while the systems are in operation.
