Vartry Water Treatment Plant in Co. Wicklow
The Vartry Water Supply Scheme provides drinking water for a supply area stretching from Roundwood, through north Wicklow up to south Dublin and serves over 200,000 people.
It was developed by Dublin Corporation in the 1860s and includes two reservoirs, a water treatment plant, a 4km tunnel under Callowhill and 40km of trunk mains that deliver water to storage reservoirs at Stillorgan in Dublin.
There was €150 million invested into the Vartry Water Supply Scheme Upgrade project, to improve the scheme and ensure that water provided complies with water quality standards set out in the European Union Drinking Water Directive and the current, national Drinking Water Regulations.
This major upgrade included three key elements:
- A new water treatment plant at Vartry
- A new link pipeline from Vartry to Callowhill
- A new covered reservoir at Stillorgan
