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 in a continuous operation over three days.Read more about the work here.
