Collection: Pre-Commissioning Cleaning

Pre-Commissioning Cleaning for Water Systems


A newly built water system undergoes various processes such as rolling, welding, and grinding before it is ready for commissioning. Newly fabricated closed water systems unavoidably contain foreign deposits like mill scale, rust, weld spatter, jointing compounds, dirt blasting grit or grease. Systems that are not properly cleaned of these contaminants before use can be subject to the unwanted build-up of sludge and bacteria over time. This, in turn, can cause corrosion, blockages and biofouling leading to inefficiencies, leaks and other costly system failures. Celtic Water Solutions supports clients on major construction projects across the Republic of Ireland with pipework flushing and pre-commissioning cleaning across a broad range of new build and building refurbishment projects. Our pre-commission cleaning solutions ensure new and existing pipework systems are commissioned correctly and in accordance with the latest BSRIA guidance to improve system reliability, efficiency and asset lifecycles.
