With changing weather patterns and increasing pressure on water resources, many landowners may be asking: can I build my own reservoir? Having your own water storage can be extremely beneficial, but there are many legal and environmental requirements to consider.
Why Build a Reservoir?
- Water Security – Storing rainwater or stream runoff ensures consistent supply during dry periods
- Irrigation – Enables better crop yields and longer growing seasons
- Conservation Projects – Can help restore habitats or support biodiversity
- Flood Management – Small reservoirs can help reduce flooding by controlling surface water release
Legal and Regulatory Considerations
Planning Permission: Most reservoirs over 2,500 cubic metres require planning permission under the Town and Country Planning Act 1990.
Abstraction Licence: If you intend to fill your reservoir from a stream, river or groundwater source, you may need a licence from the Environment Agency for any abstraction exceeding 20 cubic metres per day.
Reservoirs Act: Reservoirs holding 25,000 cubic metres or more are classed as ‘large reservoirs’ under the Reservoirs Act 1975, requiring qualified engineers, regular inspections and emergency flood plans.
Environmental Impact
Any new reservoir must be carefully planned to minimise harm to local ecosystems. Risks include habitat disruption, watercourse alteration, pollution risk and greenhouse gas emissions from stagnant water.
