DBO Contract: Veolia Water

IntroductionLimerick City's water treatment plant at Clareville is located

on the banks of the Shannon near Castleconnell. 

BackgroundFirst phase of the treatment

complex was completed in the 1890's and utilized the Shannon as a source of both raw water and power

Second PhaseThe second phase came at the

end of the 1920's when the pumping arrangement had to give way because of a more spectacular development on the other side of the river. 

Latest PhaseIn 1951, a further extension

was completed increasing the capacity to 3.6 Million gallons/day (16,000m3/day) to cater for the growing demands of the city

Public Private Partnership

The DBO option was preferred for Clareville Water Treatment Plant and a contractor has been in operation on the site since 2007.  The upgrading of the Plant was officially opened on 25th June 2010.  For Further information please read the attached brochure
