Kilmore Quay Sewerage Scheme

At a Glance

Uisce Éireann, working in partnership with Wexford County Council, has completed the construction of a sewerage scheme in Kilmore Quay, which has ended the discharge of raw sewage into the Eastern Celtic Sea. John Sisk & Son Ltd. delivered the works on behalf of Uisce Éireann. The scheme involved the construction of a new wastewater treatment plant that will serve the population equivalent of 850 people. New below ground pumping stations with above ground kiosks, pipelines to transfer sewage from the pumping stations to the wastewater treatment plant and new treated wastewater pipeline to discharge treated wastewater from the new wastewater treatment plant to the existing discharge pipe were all part of the project.

Waste water treatment plants play a critical role in maintaining the health and well-being of our communities and environment. These facilities operate tirelessly to treat and manage the water we use daily, ensuring it’s returned safely to our ecosystems. However, the rigorous conditions within these plants often lead to wear and tear on infrastructure.

The client needed a durable, safe and low cost solution for the trench covers, inlet channel covers, and access platforms. Steel is much more costly and would be very heavy to lift for the access hatches, it also would require much more maintenance.


Our team has unparalleled expertise in the planning, design, and installation of GRP systems for water supply infrastructure, treatment facilities, pumping stations, and water storage facilities. GRP was the preferred choice of material for the project for a number of reasons.

One of the primary challenges faced by traditional materials like steel is their susceptibility to corrosion and chemical damage in waste water treatment settings. GRP is inherently resistant to these corrosive agents, ensuring a longer service life and reduced maintenance requirements. This translates to cost savings and uninterrupted plant operations.

GRP’s lightweight nature doesn’t compromise on strength. This means easy installation and with the access hatches, one person can safely and easily open them for access. A win-win for construction timelines and overall plant integrity. Safety is paramount in waste water treatment plants.

GRP comes with built-in anti-slip properties, ensuring secure footing for plant personnel even in wet and hazardous conditions. This inherent safety feature enhances the working environment and reduces the risk of accidents.

GRP is an eco-conscious choice – with an exceptional strength-to-weight ratio, GRP will reduce the overall carbon footprint of a project. Products made from GRP can offer significant environmental benefits because of their characteristically low weight, good mechanical properties, and excellent resistance to corrosion.

Using GRP signifies more than just an infrastructure upgrade. It represents a commitment to innovation, sustainability, and operational excellence.
