- 12 - REPORTS OP MEETINGS 1970 February 21st. General Meeting No. 1158. The Abbey Mills Pumping Station, West Ham. On the 21 st February the Club held a meeting to examine the heart of London's drainage system, namely, the Abbey Mills Pumping Station. Constructed between 1865 and 1868, the station was part of Sir Joseph Bazalgette's scheme for the main drainage of London. The central building reflects the splendour of the architecture of Victorian municipal engineering, being built by Bazalgette and Cooper in the Venetian Gothic style and showing strong Ruskinian influences. It was within this cruciform building under the octagonal Lantern at the crossing, that the eight massive steam-driven beam engines laboured to keep London free from flooding. Originally, the station had its own reservoir to keep the boilers supplied with water, and a direct access to the railway so that the millions of tons of coal required over the years could be delivered directly into the massive cellars under the building. The Beam engines were removed between 1931 and 1933, but we were fortunate to see two beam engines in the West Ham pumping station nearby. However, we were not so fortunate in that both were being serviced, which the station superintendent informed us, happened all too frequently. The pumping at the Abbey Mills station is now done by eight, electrically-driven centrifugal pumps with a gross capacity of 224,000 gallons a minute, compared with 112,000 gallons a minute originally attained by the beam engines. To augment these, there are three diesel-driven pumps, one electrically-driven and seven gas-engined centrifugal pumps, which in all have a gross capacity of 206,000 gallons a minute. The gas engines are started with the use of compressed air and use town gas supplied from a nearby gas- holder. Members were given a demonstration of one of these pumps in action, it being specially started up for our inspection. The total capacity of the station is thus
