“Future Source. Water for Generations“ project of the Lake Constance Water Supply Association, Germany

To ensure a secure and climate-resilient drinking water supply for the coming decades, the Lake Constance Water Supply Association has launched the “Future Source. Water for Generations” project.
This project involves modernizing the existing waterworks at Sipplinger Berg, with Fichtner Water & Transportation contracted to provide engineering services for integration of the existing Süßenmühle source station as well as construction of the new Pfaffental source station. A total of three new lake waterworks with ultrafiltration plants as well as independent extraction pipes from Lake Constance are planned, which will feed the ultrafiltrated Lake Constance water to the water treatment plant being modernized on Sipplinger Berg.
A reliable, high-performance and efficient power supply is also a prerequisite for a future-proof drinking water supply. Fichtner’s head office has been contracted to engineer the entire power supply for the project. This includes the conversion and new-build of switchgear, cable connections and emergency power systems as well as the civil engineering design of the associated switchgear buildings at several locations.
Fichtner Management Consulting supported this major project right at the early planning phase with a value management approach to ensure an optimum balance of function, time and cost-effectiveness at various quality gates.
