This building was built as a sewage pumping station but has now been replaced by modern pumps outside the building. The Erewash Canal Preservation and Development Association has repurposed this building for canal water supply by back pumping from below the entrance lock to the Cromford Canal's Great Northern Basin. The pumping is done by an electric pump but the house also contains the original sewage pump that has been reinstalled and is driven by a single cylinder steam engine. For the canal festival a steam roller was supplying steam to the engine.
This shows the original pump (the pump cylinder is under the photographer) with its drive from the steam engine by lineshaft, belt and fast and loose pulleys.
