The peak demand event in 2015 in the supply area of the Hessenwasser GmbH & Co. KG

Abstract

For the first time since 2003 a relevant peak demand for water occured in southern Hesse in the summer of 2015. The relevant figures in extremely dry years and especially during distinctive heat waves in the summer months are crucial for planning and dimensioning the technical facilities and for the groundwater management. On July 3rd 2015 the water demand in the supply area of Hessenwasser reached the pre-calculated value for such an event almost exactly. The demand peak was covered without any relevant problems. This shows the strength of the supply concept as well as the resilience of the pipe compound system in southern Hesse. Having said that the event revealed indeed the limits of capacity and supply risks and therefore proves the need for stated measures, which are named in the studies about the situation of water supply in the region.
