What Makes Cookstown's Water Unique?
Local geology and source profile
Residents of Cookstown receive their water from Northern Ireland Water, drawing from Lough Fea Reservoir located in the scenic Sperrin Mountains of County Tyrone. This raw water is then expertly treated at the Lough Fea Water Treatment Works before being distributed to homes and businesses. The utility is committed to providing a safe and reliable water supply.
The water's journey originates in the upland region of the Sperrin Mountains. This area is characterized by ancient igneous and metamorphic rock formations. These geological features are known to yield water with very low mineral content, resulting in exceptionally soft water. The natural geology is the primary factor determining the water's mineral composition as it flows into the reservoir.
With water hardness measured at a mere 3.5°Clark, you'll notice that soap and detergents lather up easily, and laundry comes out feeling softer. This soft water is gentle on your plumbing and appliances, reducing the buildup of scale inside pipes and your water heater. You likely won't need a water softener, but if you prefer a different feel for bathing or washing, simple adjustments to soap usage are usually all that's needed.
Geology & Source: Sperrin Mountains upland; igneous and metamorphic rocks produce soft water
