Ipplepen STW
The monitor is reporting and shows no discharge.
This overflow spills far more than most.
On the analysis this is one of the catchment's heavier or longer-running overflows. Its treatment works is not recorded as over capacity, so the volume is worth explaining. See the record below, and how the verdict is reached.

We cannot check the works — its permitted flow or population served is missing from the public record.

A flagged problem with no active measure against it. That is a gap in the public record.
What you can do about this one
Ask for the data
Under the Environmental Information Regulations, Ipplepen STW'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.
Put this on the national record
This is the fastest way to act on what you have seen. Our petition asks the Government to publish a fix-by date and yearly progress for every storm overflow. At 100,000 signatures it must be considered for debate in Parliament.
