Why Murphy?

Murphy has been a crucial delivery partner for well-known water companies for many years. Our work throughout the asset management programme (AMP) cycles has cemented our reputation as a reliable and agile contractor. Now we have our own process engineering expertise, we have a growing pool of resources to deliver a range of projects effectively from start to finish. This includes our own laboratory in Ireland, where we carry out water quality testing and treatment.

We pride ourselves on early contractor involvement and can offer a full and comprehensive service through in-house design, construction, commissioning, operations and maintenance.

We specialise in water and wastewater treatment plants, reservoirs, pumping stations, tunnelling, pipelines and networks, and water main construction and renovation.


As a provider of intelligent and efficient solutions for the water sector, we support clients that include Thames Water, Irish Water, United Utilities, Northern Ireland Water, Affinity Water and South East Water.

We work on current AMP6 frameworks for clients including Thames Water, Sutton and East Surrey Water and Bristol Water on water resilience programmes, leakage reduction, network maintenance, trunk main renovation, mains renewals and lead pipe replacement programmes.

Working Together

We also work alongside strategic partners in several joint ventures and alliances, such as AMK, KMI+, Optimise, Thames Water Infrastructure Alliance (IA) and eight2O.
