Filter Beds for the water of London.
Most of London’s reservoirs are in the open air, and the water is carefully filtered before it reaches the consumer. This picture
shows filter-beds at Kempton Park, near London, one being
emptied of water while the sand is cleansed.
Here we see a filter-bed in course of construction. First of all
pipe lengths are laid closely together, through which the water
can percolate. Above are several layers of gravel and sand of
varying coarseness and of depths ranging from three inches to fifteen inches. The gravel and sand arrest not only solid
impurities, but also dangerous microbes..
