A major engineering milestone has been reached on what is set to become the UK’s first new reservoir in more than three decades.
Portsmouth Water said teams at Havant Thicket Reservoir installed a 20‑tonne steel cut‑off wall during a continuous 72‑hour operation at the start of the year.
The wall, which is 13m (43ft) high and 9m (29ft) wide, was built on site before being lifted into a deep trench using a 100‑tonne crane.
