Getting to the outfall of this CSO was a bit tricky. Having found the area above, there didn't appear to be any easy way down due to the steep drop to the river bank. Anyhow there was an easy way into the river quite a bit further downstream, so from there I waded my way back up to the outfall. This took a bit of patience but for the most part was reasonably straight forward.

Getting through the grille of the concrete outfall was a tight squeeze.

About 15 metres through some 5' (approx) RCP is a small chamber where the tunnel changes to an RCP half-pipe, about 6' tall.

This continues on for about 200 metres or so, curving to the right, leading to the overflow chamber.

This appears to be a final overflow for one of the main interceptor sewers before making its way to the treatment works.

A higher level within the chamber gives access to a penstock control. This level can be accessed from below however it would mean pushing up an iron manhole cover, & I didn't want to stay in here for too long due to the poor air quality.

From here I made my way back to the outfall.

Yeah, I have never seen that half pipe set up anywhere before. Thanks for explaining the reason behind it Ojay.
