Why this one spills
The problem here is local, not the works.
This overflow spilled 1149 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 →The same works has emergency overflows too
All emergency overflows →8 pumping-station emergency overflows feed Dartmouth 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 2,903 recorded hours.

Verdict
Past measure, still failing
The only measures on record are already complete, yet the overflow is still flagged — so further action is needed. That is a gap.
What you can do about this one
OPEN NOW
Ask for the data
Under the Environmental Information Regulations, Mayors Avenue pumping station, Dartmouth'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.
BY 30 APR 2027
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.
BY 1 NOV 2027
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.
