If you trace the path of waste water to Budds Farm Treatment Works, on the shores of Langstone Harbour you may think the process ends there. Unfortunately not.
From one of my previous posts:
Storm water causes most of the unscheduled releases. The seawater locally can have absurdly high levels of e.coli.
Hence the local joke:
Are you swimming in the Solent?
No, just going through the motions.
