What this means →
Why this one spills

The problem here is local, not the works.

This overflow spilled 42 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.

What you can do about this one

OPEN NOW

Ask for the data

Under the Environmental Information Regulations, MILL CREEK SPS_PSCSOEO_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.

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.
