The message is quite clear from the perspective that our duty is to provide quality water that is compliant with regulations – “Kiltiernan GWS’s water is one of the best waters in the Galway Bundle No.2. Additional treatment is not justifiable from the drinking water legislation/water safety point of view.”
Also additional treatment may not address the issue of those who require it most while the cost incurred would be quite substantial.
With reference to the document below, the WHO indicates that there are some benefits to hard water.
In conclusion the board of directors have decided not to invest in measures to soften the water, at this point in time.
