Considered one of the largest improvement projects carried out for Northern Ireland Water (NI Water) in recent years, the Drumaroad Water Treatment Works scheme provides benefits for over a quarter of Northern Ireland’s population. The project involved the design and delivery of a new Clear Water Basin (CWB), including a new interstage pump station, valve chamber and connection pipework. With a capacity of 36 million litres, the water storage tank is equivalent to 14 Olympic sized swimming pools and serves the existing Drumaroad and Chapel Hill water pumping stations.
To ensure minimal disruption to NI Water customers, all shutdowns were planned with a minimum eight weeks’ notice and followed up by two weeks’ notice with the submission of Planned Works Notification. NI Water operational and customer requirements were achieved by ensuring the network was able to supply the customers from other water treatment works during the shutdowns. Early contractor involvement was carried out to maximise value in delivering the employers requirements. Following a land deal with a local landowner, all soil was kept on site and returned when works were completed. As less transport was required to remove and return the material this method helped reduce the site's carbon footprint. In the early design stages of the project an assessment of the temporary works requirements was carried out to determine how the existing services, access roads and Water Treatment Works could remain operational during the construction process.
“I would like to thank the NI Water project team, including contractor GRAHAM and RPS, who provided project management and technical support. The team successfully completed the new tank, while ensuring our customer’s water supply wasn’t interrupted during construction. This major project will provide improved local water supply for many years to come.”
