Top 11 Water Treatment Companies in Ireland

Water supply services in Ireland are governed primarily by the water services Act of 2007 to 2014 and regulated by the commission for energy regulation. For wastewater treatment, about 1.6 billion liters of water are treated each day nationally, with the wastewater in urban area sewers receiving at least secondary treatment. Water treatment companies in Ireland treat about two-thirds of all the water in the country.

In Ireland, water resources are abundant, and 83% of drinking water comes from surface water and 18% comes from groundwater. However, wastage levels were estimated to be at 800 million liters lost each day in the year 2015.

The quality of the water accessible for public use is usually quite high, with 98% of public water supplies complying with the standards for E. coli levels in 2004. However, the microbiological quality of some rural water supplies remains to be seen.

Wastewater infrastructures include 25,000 km of pipes to approximately 1,000 wastewater treatment companies.

Ireland’s water has many problems such as water hardness, excessive chlorine, fluoride, iron, and manganese in private wells. Water hardness or lime in water is a common problem in Ireland, especially in areas like Dublin, Meath, Kildare, Carlow, Louth, Wexford, Cork, and Limerick. It can become a very serious problem for homeowners who aren’t aware of it.

Hard water contains a high amount of dissolved salts of calcium and magnesium, which cause a thick white layer buildup on water appliances such as electric kettles, washing machines, dishwashers, and boilers. This results in poor performance and efficiency of appliances thereby leading to an increased operational cost.

While hard water is not only harsh on your appliances, it is harmful to you and your family’s health as well. Research has proven that hard water causes skin irritation, dry skin, hair fall, and dull hair
