Existing facilities such as flood-control reservoirs and similar constructions are being pushed to the limit of their capacity much more often than was planned. This means that the primary objective of flood protection in the vicinity of rivers and streams can no longer be assured to the same extent as it was, for example, 20 years ago.

The Freusburger Mill in Kirchen an der Sieg, formerly used for milling grain by water power, ceased operation in 1978. Since then, it has been used for generating hydroelectric power. An ASK-Weir was installed in 1992 and has significantly increased its efficiency.

Europe's largest fully automatic bar-screen plant currently in use in a mixed-water spillway started operation in Darmstadt. The city of Darmstadt specified the requirements beforehand in a tendering competition. The order for the manufacture, supply and installation of the fine-screen unit was placed with HST Hydro-Systemtechnik. The fine screen is for catching coarse and solid suspended matter in an existing discharge plant. The discharge plant was fitted with the screen unit to clean the water overflowing into the main outfall and to trap suspended substances in the sewer which had previously caused considerable water pollution.

HST Hydro-Systemtechnik received a rather unusual order. It was the first fruit of HST's joint effort with Hankook Filter Co. in Seoul.
