With their appealing colour, clear waters, and beautiful backdrop, Chinnor Quarry pit lakes drew huge crowds of illegal trespassers during the 2020 Covid-19 lockdown (as reported on BBC News
). However, old quarries are dangerous and unsafe for swimming. Water depth can drop suddenly, temperatures can reduce rapidly below the surface, and chemicals can be present causing skin irritations and stomach upsets.
Concerned for public safety site owners Taylor Wimpey quickly deployed security staff to the site. Whilst this deterred some members of the public, many found their way back to the quarry. For Taylor Wimpey, their next source of discouraging people from the site was to reduce the attractiveness of the lakes. The High Wycombe based company sought an innovative contractor, with experience in water engineering
and environmental services
, who could meet the urgency of their needs.
