Rehabilitation elevated tank Dörnberg II
Our engineering office successfully completed all service phases in accordance with HAOI as part of the planned project “Refurbishment of the Dörnberg II elevated tank”. Elevated tank Dörnberg II is operated by Wasserbeschaffungsverband (WBV) Dörnberg, the provider of the municipal water supply.
WBV Dörnberg is responsible for providing drinking and extinguishing water for the municipalities of Ahnatal and Habichtswald in northern Hesse. About 13,000 inhabitants are connected to the public water supply in these areas, in addition to agricultural enterprises and other businesses as well as public institutions such as schools, nursery schools and sports grounds. Most of the drinking water reservoirs of WBV were built in the 1970s. All pipes still consist of cast iron (SGCI). WBV Dörnberg has decided that all pipes within the drinking water reservoirs shall be gradually replaced with stainless steel pipes. In addition to the renewal of the pipelines in the elevated tank Dörnberg II, minor demolition work, new lighting and a new entrance to the water chamber have been carried out.
What needs to be considered when renovating an elevated tank?
When renovating elevated tanks, particular attention must be paid to ensuring the water quality and extending the service life. Deposits must be removed regularly and the leak tightness and function of the technical equipment must be checked. Damage caused by corrosion, material fatigue or leaks requires targeted repairs, the replacement of wearing parts and the application of new protective coatings. Careful planning of the refurbishment is necessary, as work often requires the temporary shutdown of the tank. Specialist knowledge and precision are crucial to ensure the reliability of the drinking water supply. Overall, refurbishment serves to maintain operational safety and minimize water losses.
