Hochwasserrückhaltebecken Haintal, Detention basin in Heidenheim an der Brenz, Germany.
The Haintal detention basin is a dam structure in the Brenz valley designed to hold large water volumes during floods. The facility was built specifically to protect nearby residential areas and industrial sites from overflow.
The basin was built following a devastating flood in 1968 to prevent similar disasters from occurring again. Construction was an important step toward improving flood protection in the Brenz valley and surrounding region.
The basin sits within a region shaped by limestone formations that affect how water moves through the land. Locals connect this place to flood protection and nature in an area defined by springs and underground streams.
The site is easy to access and can be viewed from outside, though it is primarily a technical facility for professionals. Visitors should note that this is an active system and cannot be freely entered.
The Haintal stream remains dry for most of the year and only flows during heavy rainfall. This system takes advantage of the stream's natural dryness to store water and protect the surrounding area.
