Work has been completed as part of a £2.7m investment scheme to improve safety at Eccup Reservoir.
Engineering specialists, Mott MacDonald Bentley have carried our work to replace the existing pipework that runs under the embankment of the reservoir.
Eccup reservoir was constructed in 1897 and supplies water to the Headingley water treatment works. Lee Laherty, Yorkshire Water project manager, said: “This was a huge scheme; the pipe we installed was 1.4 metres in diameter and part of the new pipe had to be constructed under water by specially trained divers.”
A new safety project will begin at the site next month.
