Replacement of 600 metres of ageing water mains, improving security of supply for over 1,000 customers

Irish Water and Kildare County Council are working in partnership to replace 600 metres of ageing water mains in Maynooth. Irish Water is investing €350,000 in the project which will involve the replacement of ageing cast iron and PVC water mains with heavy duty plastic pipes. This project will improve the security of the water supply for customers, improve water pressure to properties, reduce leakage in the public water network and replace shared backyard services with a single more robust connection to the new water main from each property.

Work on the project commenced on 18 September 2017 and will take 15 weeks to complete.  The project will benefit over 1,000 residential and business customers by strengthening and reinforcing the water network, reducing disruptions in their water supply by reducing leakage and unplanned outages when bursts occur and improving water quality. Upon completion, there will be significant improvements in network performance and levels of customer service in terms of efficiency and security of supply.

The work will be carried out in short sections to minimise impact on residents, businesses and road users. The works will involve some short-term water shut offs for a number of hours over a day or two in each area when the pipes are being connected to the system. The project team will ensure that householders and businesses are advised of any works in their area in advance and will be given 48 hours prior notice of water shut offs.

The properties that will benefit from the works in the areas listed below are served by backyard water mains. This project will involve the replacement of water mains and water service connections to 120 properties currently served by water mains located in backyards and private properties.  The works to replace the common backyard services will involve laying a new water main in the public road, adjacent to the property, and connecting the water main to the property with a new service pipe within the boundary of the property or within the property itself. 

The works will take place in the following areas:

  • Mill Street / Pound Lane
  • Double Lane / Cross Lane / Buckley’s Lane
  • Convent Lane (South)
  • Leinster Park

Commenting on the project, Ivan Corcoran, Capital Programmes Lead at Irish Water, said “The replacement of ageing and fragile water mains will ensure that customers in Maynooth have a more reliable and secure water supply. The new water mains are made of heavy duty plastic pipes which will replace old Cast Iron and PVC water mains that were prone to frequent bursts. Removing shared backyard service connections will provide improved water supply to the 120 properties that are included in the project. This investment is part of Irish Water’s ongoing investment to upgrade ageing water mains across Ireland”.

Residents and businesses in the areas included in the project will be notified ahead of the works commencing and provided with contact details should they have any questions. During the works a comprehensive traffic management plan will be in place and alternative access arrangements agreed with local residents during construction there will be appropriate phasing of work crews to minimise disruption and an avoidance of works during peak traffic times.

This project forms part of Irish Water’s investment plan. Works have been prioritised to address the most critical issues in line with commitments outlined in Irish Water’s recently published Business Plan. Delivery of the business plan will involve a €5.5 billion investment in capital spending on drinking water and wastewater quality and capacity and new infrastructure up to 2021.
