NI Water complete essential sewage project in Northern Ireland

NI Water has announced the completion of an essential programme of sewer improvement work, representing an investment of over £900 000 in the Holywood area, Northern Ireland.

The work involved replacing the existing sewage pumping main between an existing pumping station beside the Holywood Bypass (near Sullivan Close) to the Kinnegar Wastewater Treatment works site. A new innovative structural spray lining technology was used on short sections of the main to minimise disruption when crossing the A2 carriageway and railway line. This work will enhance the sewerage infrastructure in the area and reduce the maintenance required on the network along this busy route.

NI Water’s Senior Project Manager, Peter Ferguson, said:

“We are delighted to complete this essential improvement programme in the Holywood area, which involved the installation of a new pumping main to transfer effluent from Holywood A Wastewater Pumping Station to Kinnegar Wastewater Treatment Works for treatment.

“This challenging contract took place along the busy Holywood bypass route and also involved extensive pipelaying to improve the existing pipe sections situated at the hard-shoulder of the A2 and under the existing Bangor to Belfast railway line.”

“The team is proud to be the first in Northern Ireland to employ a new innovative structural lining technology, which is a special underground structural lining spray, used to improve sewer pipelines. The new lining helped the team work more efficiently, as well as reducing the impact on this main arterial route between Belfast and Bangor, with challenging constraints involved such as working close to a high pressure gas main and other services.”

This investment at Holywood is an excellent example of what can be done when the necessary funding is in place.

NI Water’s goal is to ensure modern, efficient service today and in the future. While underfunding of NI Water is an issue, the company is working hard at a local level to find solutions to enable councils and developers to progress visions and facilitate future economic development.

NI Water is ready to provide engineering solutions to short-term constraints where possible, however full funding identified by the Utility Regulator in its Draft Determination (PC21 business plan) is required to fulfil the vision of economic expansion for Northern Ireland’s towns and cities.
