  1. CASE STUDY NENAGH REGIONAL WATER SUPPLY PLANT

  2. PUBLIC WATER SUPPLIESPERSPECTIVE • BOTTLED WATER USAGE in IRELAND = 0.3 million Litres / day • NENAGH R.W.S.P. PRODUCTION = 7.5 million Litres / day • NORTH TIPPERARY Co. Co. PRODUCTION = 26 million Litres / day

  3. PUBLIC WATER V’s BOTTLED WATER

  4. SUPPLY√TREATMENTX

  5. NENAGH R.W.S.P. COMMISSIONED - 1997 • ISO9001 - 1998 • HYGIENE MARK - 1999 • Q – MARK - 2000 • ISO14001 - 2003 • E.T.P. - 2005
