As summer gets under way and pesticide use increases across farms, gardens and public spaces, NI Water is encouraging farmers, the amenity sector and domestic users to take extra care when storing, applying and disposing of these products to help protect drinking water sources and the wider environment.
Working alongside partners through initiatives such as the Water Catchment Partnership, NI Water is helping raise awareness of how everyday practices can affect water quality and what simple steps can reduce pollution at source. Pesticides used for weed control are often detected in rivers and lakes, where they can pose a risk to aquatic life and increase the cost and complexity of treating drinking water.
While pesticides play an important role in agriculture, landscaping and garden maintenance, summer conditions can increase the risk of products entering drains, streams, rivers and reservoirs - particularly if they are applied carelessly, spilled during handling, or used before rainfall. Careful storage, application and disposal are essential to minimise these risks and protect local waterways.
A number of simple but effective measures can help safeguard Northern Ireland’s waterways:
Follow guidance and best practice: All users, including farmers, groundskeepers and householders, should follow product labels and relevant guidance. Professional users are advised to consult qualified agronomists and adhere to recognised codes of practice.
Store and handle safely: Pesticides should be stored securely to prevent leaks or spills. Professional users should ensure spraying equipment is regularly checked and calibrated to reduce the risk of drift or run-off.
Plan applications carefully: Avoid applying pesticides before heavy rain or during windy conditions. This reduces the risk of chemicals being washed into drains, rivers and lakes or drifting beyond the target area.
Dispose of waste responsibly: Empty containers and unused products should be disposed of correctly. Professional users must use approved waste contractors, while householders should follow local council guidance.
NI Water catchment officer Peter Quinn said: “Everyone who uses pesticides, whether on farms, in amenity spaces or in the garden, has an important role to play in protecting our waterways. Through partnerships like the Water Catchment Partnership, we are working to raise awareness and promote practical steps that reduce pollution. By working together, we can protect our drinking water, support biodiversity and maintain Northern Ireland’s strong environmental reputation.”

NI Water’s Sustainable Catchment Area Management Practice (SCaMP) team works to protect and improve raw water quality through nature-based solutions, aiming to protect and enhance raw water quality and reliability in our drinking water catchments through sustainable catchment-based solutions that focus on protecting and enhancing the natural environment. The NI Water SCaMP team aims to improve water quality at source before it is fully treated for drinking.
