Moreover, the discharge of warmed water back to the river has been regulated by public law. Improved municipal waste water treatment and the decline of coal mining have had positive impact on the water management, too. The water demand for shipping nevertheless is important in the West German canal system. To compensate the loss of water from evaporation, infiltration and locking in the sluices annually 500 million m of water have to be injected. To reduce especially in dry weather periods the demand of water that gets lost from the sluices it is locally pumped up again. The total water demand from the canal system of up to 800 million m/year is mainly covered by supply from the Lippe and Ruhr. The permission to withdraw up to 25 m/second from the Lippe still today is limited to a remaining discharge in the Lippe of 10 m/second. If the water level in the river falls below that flow rate the Lippe receives up to 4.5 m/second out of the canal system for low water replenishment. For example in the 12 months period from November 2014 to October 2015 the Lippe discharged on 257 days water into the Datteln-Hamm Canal and on 102 days canal water was pumped into the Lippe.

Moreover, the permission for maximum discharge of the Lippe into the West German canal system was increased to 10 m/second again but now with the additional limitation to guarantee a minimum discharge of 10 m/second in the Lippe, too, otherwise the water abstraction for the canals had to be limited. This regulation was possible because of already constructed pumps at the sluices that started compensating partly the loss of water from locking. In the years 1973-1978 a series of new pumping stations was established that could serve the canals “upstream” from the rivers
