The objective of water management planning is to maximise the availability of regional water resources to meet the usage requirements of individuals and of society as a whole and to provide effective sewage treatment, flood protection, and groundwater management. The guiding principle of water management is preserving water resources while taking the natural water cycle into consideration. This article lays out the legal framework, the urban water management infrastructure, town and country planning aspects, and future areas for action.

The required weighing of interests is the principal limitation on the planning authority’s freedom of discretion. It is applicable across all forms of spatial planning and requires each decision-maker concerned to include all interests in the weighing process that are relevant under the circumstances, to not underestimate the relevance and significance of the interests concerned and, finally, to reconcile the respective interests in a manner that is not disproportionate to the weight of individual concerns.
