Blocking drainage
Now we are paying again to reverse the failed policy and fill in the drainage channels.
The scheme costs £2.2m. "It's having huge impact," said Dylan Bright of South West Water.
"By the time the restoration of the catchment is completed, the moor will be able to hold the equivalent of more than 6,000 Olympic-sized swimming pools of water. It'll hold back rainfall from flowing down to places like Exeter."
