As Northern Ireland enters the wetter autumn and winter months, NI Water is drawing attention to the role of natural landscapes in managing flood risk. The utility says restoring peatlands, planting trees, and improving upland areas can slow the movement of rainfall into waterways.

Through its Sustainable Catchment Management Programme (SCaMP), NI Water works with farmers, landowners, and partner organisations to improve the condition of land surrounding reservoirs and rivers. The programme includes peatland restoration, tree planting, fencing, blocking drainage channels, and changing land management practices.

Healthy peatlands and soils act like a natural sponge, absorbing rainwater and releasing it gradually. This reduces surface water run-off after heavy rainfall and can ease pressure on streams and rivers, contributing to wider flood management efforts.

An NI Water spokesperson said that flood resilience is not just about hard infrastructure. The natural environment has a vital role. Restoring catchments that supply drinking water helps slow the flow of water, support biodiversity, store carbon, and improve water quality entering reservoirs and rivers.

The programme also aims to protect water quality before it reaches treatment works. Restoring damaged peatlands retains carbon in the landscape, while healthier habitats support wildlife and improve the ability of upland environments to cope with changing weather.

These improvements are particularly relevant as heavier rainfall and other effects of climate change place increasing pressure on natural environments and water management systems.

NI Water says natural restoration cannot prevent flooding on its own, but can complement other measures designed to manage rainfall and protect communities. A spokesperson added that nature-based solutions are not a standalone answer to flooding, but healthy catchments are an important part of the wider picture and can help build long-term resilience.
