WARFLEET CREEK SPS_PSCSOEO_DARTMOUTH
The monitor is reporting and shows no discharge.
This looks like a fault, not a storm.
This overflow has discharged in dry weather 41 times since 2020 — spills with no rainfall to excuse them. Its treatment works is not itself over capacity, so a catchment-wide explanation does not hold. Applied to this record, the two-stage lawfulness test is hard to pass: a recurring dry-weather discharge is not an exceptional circumstance, and where the remedy is routine maintenance the disproportionate-cost exception is hard to run.
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.

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
Ask for the data
Under the Environmental Information Regulations, WARFLEET CREEK SPS_PSCSOEO_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.
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.
