Ferry Boat pumping station, Dittisham
The monitor is reporting and shows no discharge.
This looks like a fault, not a storm.
This overflow has discharged in dry weather 37 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 →Can its works cope?
Full capacity view →This overflow drains to Dittisham Main STW on a 66 m³/day permit.
The works has headroom — so spills here point to another problem, often on that branch of the network (a blockage, a failed pump or infiltration).

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, Ferry Boat pumping station, Dittisham'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.
