New water withdrawals
The Water Protection Act specifies how appropriate residual flows can be determined. This applies to new water withdrawals and also to existing withdrawals for which concessions have to be renewed.
Anyone who withdraws water from a permanent (non-seasonal) watercourse - for power generation, irrigation or cooling purposes - requires a licence. This will only be granted if appropriate residual flows are maintained in the river- or streambed.
The residual flow regulations are only applicable to new water withdrawals and to existing withdrawals when a concession expires and has to be renewed. Appropriate residual flows are calculated separately for each watercourse and withdrawal site.
