I first checked this out at least 5 years ago now but i didn't get into any of it back then. Its nothing amazing but seeing as we were in the area i thought it would be a good idea to go have a better look. The quoted history explains most of what you would need to know. The main station is used as some sort of carpentry workshop now so these photos come from the derelict 'ancillary building'.

Its a great piece of architecture thats for sure, if Norwich were a little closer id go hunt down the sewers mentioned in the text, bound to be epic!

[The estate was owned by the Money Family - sold to Sir Robert John Harvey in 1861, and to Jeremiah James Colman in 1872.] Deep sewers were laid on both sides of the Wensum and a pumping station was built in Trowse which brought some improvement in form of the Whitlingham Sewage Farm. Provision was included for the construction of a new road past the site which led to the widening of the bridge over the River Yare. The original pumping station, situated south-east of the railway line, acts as an important landmark which is most apparent from the large blue brick railway bridge.

The sewage works consists of three historic buildings:

The original pumping station is red brick and built in classical style. A modern extension was added to the south but the original façade remains unaltered.

An ancillary building, designed with various early 18th century details such as the door surrounds and detailing around the windows, adjoins it. It was opened by the Lord Mayor and local historian Walter Rye on 14 July 1909. The datestone commemorating the event is still in place.

Immediately east of it is a row of six workers' terraced cottages built in Victorian Gothic style with polychromatic detailing of red and white bricks. Unfortunately many of the original windows and slate roofs have been replaced by modern materials.

A modern pumping station has been built to the south-east of the complex.
