MILL CREEK SPS_PSCSOEO_DITTISHAM
The monitor is reporting and shows no discharge.
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
Ask for the data
