The initiative is part of Welsh Water’s pledge to reduce its greenhouse gas emissions by 50% over the next 25 years. The programme saw old-style T8 fluorescent lamps replaced by energy-efficient equivalents at 41 Welsh Water sites.

More than 9,600 lamps were replaced in the programme, mainly on operational water and wastewater treatment plants

However, to avoid removing and replacing all the light fittings, the company chose to install a retro-fit, plug-in converter from Energys Group called ‘Save It Easy’. This allowed existing light fittings to be used with the new T5 lamps.

Welsh Water energy innovation & programme manager Adam Fairman said: “The Save It Easy installation was a big job, involving dozens of sites – many of them industrial treatment plants… the project was non-disruptive and well-organised.

“We were able to accomplish our goal to reduce our carbon footprint, without compromising the safe running of the company.”
