London’s Nine=Million=Gallon Supply.
London, though ancient and ponderous, appears to realize more keenly than many American cities the importance of having pure water in adequate quantity. On the theory that filtration alone is not a satisfactory method of purifying water, London is finishing a series of storage reservoirs, so that all of the water used will have a chance to stand a few days undisturbed. There already are 62 of these reservoirs, with a total capacity of 8,913,000,000 gallons, which is enough to supply London 39 days. The new reservoir adds enough for 13 days more. It is two-thirds of a mile wide and a mile and two-thirds long. Because the country around is flat and allows the
wind to get a great sweep before reaching the basin, there might be a danger that large waves would be raised. To guard against this, the reservoir is to be divided into two sections by a wall. The water is to run to the basin through five lines of pipes and flow over a number of artificial waterfalls on the way. The River Lea, the source of the new supply, is like American rivers in one respect at least—it sometimes outgrows its channel. The engineers diverted the course of the river fer three miles to make it easier to manage, making a new bed for it lined with brick and cement. The work was done at an estimated cost of $2,750,060. The bed of the reservoir was dug in clay. The sides are to be lined partly with brick and partly with cement.
Fire company zones in Austin, Tex., have been completely readjusted. There is no part of the city which is not covered by two fire companies, and in most cases three will respond to alarms.
