What Makes Portadown's Water Unique?
Local geology and source profile
Portadown receives its water supply from NI Water, drawing from Lough Neagh. This vast freshwater lake is the primary source, with water being treated at the Dunore Point Water Treatment Works before distribution to residents in County Armagh. The Upper Bann river also plays a role in the supply chain, ensuring a consistent flow from the Lough Neagh system to the treatment facility.
The geology influencing Portadown's water quality is characterized by soft, low-mineral content due to the catchment areas. The water originates from regions dominated by Antrim Basalt and granite formations. These rock types are known for their resistance to weathering, meaning they don't readily dissolve minerals into the water. Consequently, the water is naturally soft, registering around 5.6°Clark.
Because Portadown's water is soft, you'll find it generally doesn't cause significant scale buildup in appliances like kettles or water heaters. Soap and detergents will lather easily, meaning you might use less product. While generally beneficial, some people find very soft water can have a slightly different taste compared to harder water. If you prefer a different mouthfeel, you could consider a remineralization filter, but a water softener isn't typically necessary for this supply.
Geology & Source: Antrim Basalt and granite catchments; predominantly soft water
