Ralph Dodd’s prepared many unexecuted or incomplete plans for public improvements in the metropolis over a 50 year period, including Vauxhall Waterworks and a Vauxhall Bridge of masonry (a scheme taken over and redesigned by Rennie c. 1809).
In 1804, he proposed waterworks for north-east London, possibly the precursor of the East London Waterworks. His proposals were set out in a paper ‘Observation on Water’ on improvements to London’s water supply.
Primarily known for his failed attempt to build a tunnel underneath the Thames (1799-1802), he was also the author of an essay on canals.
