Description

The brick sewer vent, possibly designed by engineer J.S. Sinclair around 1893, is located in the former Borough of Widnes at Mill Brow. This structure is made of red brick with a blue brick plinth and stands approximately thirty feet high and four feet square internally. The shaft tapers as it rises and features narrow sunken details on each face, with two on the lower half and one with a rounded head near the top, which includes a keystone. At the top, the vent has a weathered projecting cap supported by corbels. It is the only remaining shaft from an early sewage system that was designed to manage effluent from the chemical industry.

Local climate

Brick Sewer Vent sits in a wetter-than-average part of the UK, with an average of 1,000 mm of rain a year. This makes it wetter than 80% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 63% of listed buildings.

It experiences an average of 31 freeze-thaw cycles a year, fewer than 61% of listed buildings. Of these, 15 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.

Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
