Summers here and the sewage discharges from the overflow pipe at Trevone are still happening…

Rips and currents, and what will happen if they cut off the pipeline on the beach…
The natural sea currents that flow around Trevone are likely to effect the movements of sewage when it is discharged. The sea currents (rips) at Trevone sweep northwards through the inshore waters of Rocky beach and then out along the Madrips. So the flow of sewage, when it is discharged, will be pushed across Trevone Beach. This is probably the reason the original outfall was sited out beyond the spring low water level (and beyond the surf zone of the island).
If the discharge is taking place simply beyond the seaward edge of the slipway it will be onto the sand where all the children play, and where people walk their dogs along the rocks and go rock pooling. So the issue isn’t just bathing but more crucially wading, rock pooling, walking bare feet anywhere on rocky beach and sandy beach from mid to low tides.
Discharges of untreated sewage shouldn’t be happening, but because of where the pipe is cut off at the moment, when they do they’re even more dangerous to everyone that plays, surfs, swims, rock pools, walks etc in the Trevone area… and if Southwest Water are allowed to cut off the pipeline even further up the beach, when discharges occur again (and they will), the effects will be even more disastrous!!! Current proposals are not adequate.
