*The figures given represent the theoretical maximum capacity of the slow sand filter beds at the standard rate of 400 gallons per square yard per 24 hours. Actually however this capacity is seldom available as one bed of each plant is generally out of action for cleaning, and a deduction has been made accordingly in the total.
