Ledbetter said although nearly all of Cornwall received its water from Colliford Lake, South West Water had bought a former china clay quarry near St Austell.<\/p>\n
He said: “We’ve recently brought in Blackpool Quarry, which is an old quarry pit, which we are using as a kind of bucket to store water to really provide extra resilience, too. <\/p>\n
“We do have two or three of those already that help supply water and we know that they are a really good way of storing water because the clay pits themselves are excellent because they basically don’t leak.”<\/p>\n
Ledbetter said there had been “challenges”<\/a> with securing environmental permissions for a proposed desalination plant in Par.<\/p>\n “It could be that desalination comes back into the equation, but at the moment we’re reviewing across all the different types of options we could be looking at,” he added.<\/p>\n Follow BBC Cornwall on X, external<\/a>, Facebook, external<\/a> and Instagram, external<\/a>.
