wateropvang

Wateropvang refers to the collection and temporary storage of water, typically rainfall or surface water, for later use or controlled release. It is a component of flood risk management and water resources planning.

The stored water can serve several purposes: reducing peak runoff during storms, augmenting water supply during dry periods, recharging groundwater, and supporting ecological or recreational objectives in urban areas.

Common forms include retention or detention basins, reservoirs, water storage tanks (cisterns), and rainwater harvesting systems. In urban environments, green infrastructure such as bioswales, infiltration basins, and green roofs contribute to wateropvang by capturing rainfall and slowing runoff.

Implementation and management: Wateropvang facilities are designed, owned, and operated by water authorities, municipalities, or private entities, subject to standards for water quality, safety, and flood risk. Maintenance is required to ensure storage capacity and operation during events.

In the Netherlands and other Dutch-speaking regions, wateropvang is integrated into broader policies on water management and spatial planning to maintain safety, environmental quality, and resilience to climate change.
