Strabane Water Hardness & Quality Report (2026)

The water serving Strabane comes from Northern Ireland Water, which is the sole public utility for the region. Daily, the company supplies 575 million litres of clean water to nearly 1.8 million people across Northern Ireland. While specific reservoir or aquifer names for Strabane aren't detailed, the water is drawn from Killeter Forest upland reservoirs and treated at Killeter Water Treatment Works. Northern Ireland Water manages all water and sewerage services, and you can reach them 24/7 via Waterline at 03457 440088.

Generally, water sources in Northern Ireland are drawn from regional rivers, reservoirs, and groundwater. These sources are influenced by the local bedrock, but specific watershed or geological details for Strabane weren't provided. The Tyrone Mountains area, where the Killeter Forest reservoirs are located, is known for its metamorphic bedrock. This geology typically results in very soft water, with the Killeter supply registering at a low 2.8°Clark. This means the water has a minimal mineral content.

Because the water is very soft, you'll likely notice less limescale buildup inside your pipes and appliances, which can extend their lifespan. Soap and detergents will lather more easily, meaning you might use less product. If you ever experience temporary discolouration after network repairs, simply let the water sit in a glass until it clears. For any concerns about taste, smell, or discolouration, it's best to contact Northern Ireland Water directly. The Drinking Water Inspectorate for Northern Ireland oversees water quality, providing assurance to residents.
