Series 5a, Manchester - March 2015
Explored with ConcreteJungle and Kenni
A rather unassuming inverted brick egg outfall into the River Irwell leads us into a small weir overflow chamber. Upstream through a cack filled 1 metre RCP is the screened sewer overflow, downstream is a big holding tank that fills when the sewer is at capacity. A penstock in the screening chamber presumably closes once the tank is full preventing any discharge into the river. The downstream pipe from the weir chamber ends in a vertical drop straight into the tank, so not somewhere I wanted to be so unfortunately no photos from that side.
