Veolia awarded contract for Vartry Water Plant upgrade
THE Irish Water contract for the design, construction and commissioning of the new water treatment plant at the site of the Vartry Reservoir has been awarded to Veolia Water Ireland Ltd.
The construction of the new water treatment plant is part of a €200m investment in the Vartry Water Supply Scheme, with works due to begin later this year and expected to be completed in 2020.
The scheme was originally built in the 1860s and is in urgent need of improvement. It is also on the Environmental Protection Agency’s (EPA) Remedial Action List (RAL) which identifies water supplies that are in need of improvement to comply with drinking water regulations.
Geoff O’Sullivan, Project Manager with Irish Water said: ‘The upgrade of the Vartry Water Supply Scheme has been a priority for Irish Water since the utility took over the responsibility for water services in 2014. I am pleased to confirm that a contract has been awarded to commence work on this vital project which will replace the ageing plant with a modern facility, safeguarding the water supply for 200,000 people in Wicklow and south Dublin.
‘The scheme has had no major upgrade since it was built 150 years ago and is in urgent need of this investment.
‘The construction of a new water treatment plant at the existing Vartry reservoir site is the next phase in a wider investment project in the scheme which also includes the construction of a new 4km pipeline from Callow Hill to the Vartry Water Treatment Plant and covering the treated drinking water storage reservoir at Stillorgan. The investment in the scheme ensures that the people of Wicklow and south Dublin have a drinking water supply that meets all drinking water regulations that safeguards public health for generations to come,’ said Mr O’Sullivan.
Irish Water has also committed to providing a compensation flow of five million litres per day into the River Vartry, which will protect the ecology of the river during periods of low flow. The volume of water abstracted will be the same level as it has been since the scheme was commissioned 150 years ago.
Meanwhile, pipe laying has progressed to schedule as part of the construction of a new link from the existing water treatment plant at the Vartry to Calowhill. The works started in January of this year and are considered a priority element of the overall Vartry Water Scheme upgrade.
The works include: a new pumping station at the existing plant and four kilometres of buried pipeline from Vartry to Callowhill and a break pressure tank at Callowhill.
The final section of pipe has been laid and the construction works will be mainly confined to the sites at Callowhill Lower, the summit break pressure tank and the Vartry Water Treatment Plant. The works should be completed by December.
