In 1820 the Grand Junction Water Works Company (GJWWC) opened a new pumping station at Chelsea taking water from the Thames.
Within 10 years concern about the poor quality of the water, mainly pollution with sewage, convinced the company to move its operations to a new site by Kew Bridge which started supplying water in 1838.
Continued concern about the quality of the water taken from the tidal section of the Thames resulted in the Metropolitan Water Act of 1852 which obliged the water companies to take their water from above Teddington Weir, the tidal limit of the Thames. The GJWWC company built new intake and treatment works at Hampton, the water pumped to Kew Works which became an intermediate pumping and treatment station.
Go there; it is easy to get to, dramatic and well run.
I found a quiet corner and attempted to get the grandeur and drama of it. More learning curve that achievement. Struggled with green (often a difficult colour) and using resist for highlights which didn’t dry in time. In future will ‘lift off’ as I think that will both leave colour in the pronounced highlights and retain their softer edges.
Its all a learning curve….
