Puntwateronttrekking

Puntwateronttrekking is a term used in water management to refer to the withdrawal of water at a specific point within a water system, such as a borehole, well, or surface-water intake. The emphasis is on the withdrawal occurring at a defined location rather than being distributed along a network. The concept is common in hydrogeology and civil engineering when modeling and regulating how much water is extracted from a single pumping point for drinking water supply, irrigation, industry, or other uses.

In practice, puntwateronttrekking involves measuring and recording the discharge at the extraction point. Typical measurements include the flow rate (often in cubic meters per second) and the cumulative volume over time. Monitoring equipment, such as flow meters and data loggers, is used to ensure accurate reporting and to support compliance with licensing and environmental rules. Data from puntwateronttrekking feeds into aquifer and water-resource models to assess effects such as drawdown, groundwater level changes, and potential impacts on connected surface waters.

Regulatory and environmental considerations are central to puntwateronttrekking. Institutions granting permits often specify withdrawal limits, seasonal variations, reporting obligations, and requirements for measurement accuracy. Environmental impact assessments may examine how point withdrawals influence local ecosystems, groundwater-surface water interactions, and overall aquifer sustainability.

Applications of puntwateronttrekking include planning and operation of pumping stations, drought management, aquifer management, and scientific research. By focusing on withdrawals at individual points, managers can optimize use, monitor resource status, and integrate data into broader water-resource planning.
