Dublin City Council is to carry out €118 million worth of improvements to the city's water mains.
Dick Roche, Minister for the Environment, Heritage and Local Government, today announced that 280 kilometres of old cast-iron water pipes would be replaced with heavy duty polyethylene pipes as part of the Dublin Region Water Mains Rehabilitation Project.
Water pipes will also be replaced in parts of Co Wicklow and Co Kildare.
Many of Dublin's cast-iron water pipes, which are up to 100 years old, are corroded and may be responsible for poor water pressure in some areas as well as the daily loss of millions of litres of high quality drinking water.
Contractors will work on a street-by-street basis, and householders will experience water stoppages from 8am until 6pm during works and may suffer further water shortages before or after work is carried out.
Work on the water pipes is expected to begin this summer in the southeast of the city.
Householders will be supplied with information leaflets from six weeks before the start of work. Residents and businesses with special needs will be accommodated during the works but must inform the project developers before work starts.
