Wicklow Disinfection Programme

Water Quality Project

Irish Water has upgraded 32 Water Treatment Plants across Wicklow as part of the National Disinfection Programme.

The protection of public health and continued delivery of safe, clean drinking water is the top priority for Irish Water. Disinfection is the most important part of the water treatment process. 

Irish Water, working in partnership with Wicklow County Council, has completed a detailed assessment of the water treatment plants in Wicklow as part of the National Disinfection Programme. The programme will ensure the continued delivery of safe drinking waters to these areas, while also maintaining the security of supply. 

This programme has resulted in upgrades and standardisation of disinfection systems at 32 water treatment plants across the county to ensure continued compliance with the drinking water regulations. Glan Agua Limited has delivered this programme on behalf of Irish Water. Upgrades have been completed at: Aughrim / Annacurragh, Avoca Ballinaclash, Ballinapark, Ballinavortha, Ballingate, Ballinteskin, Ballyclough North, Ballyellis, Ballymorris, Baltinglass, Brittas, Cronroe, Drummin, Dunlavin, Eadstown, Enniskerry, Giltspur, Glenealy, Greenhills, Killavaney (Tinahely), Killballyowen (Annacurragh), Killballyowen (Aughrim), Knocknagilky, Laragh, Priestnewtown, Raheen, Raheengraney, Rathdrum, Redcross Reservoir, Roundwood Well (Ashtown), Tinahealy-Tomacork, Tinahely Regional Supply and Ballinteskin Pump Station.
