Lady Eleanor Holles School (LEH) is a prestigious all-girls independent school for ages 7 – 18 years old. Founded in 1710 in St. Giles, Cripplegate as a charity school for poor girls, LEH moved into its current premises in Hampton in 1937. The School’s academic and sporting results are among the best in the country.

Although it is only ten miles from central London, the school is set in a 24 acre green campus with lacrosse pitches, netball courts, grass tennis courts, a croquet lawn and a massive sports hall, an activity studio and a four-lane 25 metre indoor swimming pool.

LEH was given permission for a new ‘Gateway Building’ to be built, but this meant demolishing the existing swimming pool plantroom and constructing a new one 100 meters further away from the pool. This was a completely ‘new build’ project with the luxury of starting at the drawing board.

Working closely with the structural building sub-contractors, Broadwater designed the layout of the plantroom, keeping LEH updated so that any changes could be approved quickly. The first stage of the project was the decommissioning of the old plantroom, ensuring the work areas were tidied and removed equipment put into skips. Then when the plantroom walls were built, Broadwater installed and pressure tested the new trench pipework followed by the installation of the filtration vessel, circulation pumps, valves and UV system. Once the essentials of the plantroom were ready, Broadwater installed new circulating pumps with variable speed drives, disinfection using an atg UV system and chemical control using a Granudos G45 dosing system and Wallace & Tiernan Depolox Pool E700P. The system is controlled by a new PLC control panel.


“Broadwater has provided the swimming pool expertise at this school since the company was established”, says the School’s Neil Lowe. “This major project was completed on time and to budget by a team of efficient engineers who clearly knew their subject.  We cannot recommend their services highly enough and are extremely grateful to them for their support over many years.” Whilst Broadwater cannot take the credit, the UII swimming squad finished in second place at the IAPS national swimming finals at the London Aquatic Centre in June 2019 and competed in the English Schools Swimming Association finals in Sheffield, with the team winning silver medal in the freestyle relays.
