Description

One of the most beautiful thermal baths in Europe is the Ludwigsfelde Swimming and Health Centre. Under its transparent domed roof, up to 300,000 visitors per year enjoy Mediterranean bathing pleasures. Since 2005, the rainwater that accumulates on the two roof areas of 2,500 and 2,800 m² has been percolated directly on site using the DRAINMAX tunnel system, a cost-effective and space-saving solution.
