The monitor is reporting and shows no discharge.
The problem here is local, not the works.
This overflow spilled 64 times on days its own treatment works stayed shut — so the works still had capacity. That points upstream, to this branch of the network, rather than to a works too small for its catchment.
How this verdict is reached →Can its works cope?
Full capacity view →This overflow drains to BUCKFASTLEIGH STW, serving about 7,795 people.
The works has headroom — spills here point upstream, to a blockage, failed pump or infiltration.
The same works has emergency overflows too
All emergency overflows →4 pumping-station emergency overflows feed BUCKFASTLEIGH STW works — raw-sewage relief outlets that should fire only when a pump fails. They are not in this page's feed; between them they have discharged about 2,054 recorded hours.

What you can do about this one
Ask for the data
Under the Environmental Information Regulations, STONEPARK CRESCENT_CSO_ASHBURTON's telemetry, the works' flow-to-full-treatment setting, and any spill investigations are emissions information — they cannot be withheld on commercial-confidentiality grounds. A written request is the fastest lever.
Get it into the next programme
Investigations that will shape the 2030–35 environment programme must complete by this date. Putting this overflow on the record now — to South West Water and the Environment Agency — is what gets it considered.
Put it in the drainage plan
South West Water's draft Drainage & Wastewater Management Plan goes to a twelve-week consultation. A named overflow with evidence behind it is far harder to leave out.
