BTU, with its headquarters near Portsmouth, specialises in mechanical and electrical works across Hampshire and West Sussex on behalf of Southern Water, including hundreds of treatment works and pumping stations.
David Welch, BTU Framework Director, said: “Water safety is so important and what Southern Water has done in giving more than 500,000 children life-saving swimming skills is simply amazing. We are honoured to be involved in making a difference and I will be encouraging our 150-strong staff to spread the word about the scheme”.
