Water Filtration at Rangoon.

Water Filtration at Rangoon.

A correspondent of Indian Engineering gives the following brief description of the water-works at the Royal Lakes, Rangoon, and of the means by which it is attempted to filter the supply :

“ The outlet works consist of a segmental brick wall, in the face wall of which four cast-iron intake pipes of 27-inch diameter, supplied with horizontal lips, are built at different levels. On the top of each lip, when working, large gauze strainers are fixed, the lips of the intake pipes being turned in recess to receive them, and it is through these double-gauze strainers that the water has to pass before entering the well. In the well are two trench pipes of 27-inch diameter, which are also supplied with horizontal lips to receive, these are likewise fitted with gauze strainers, so that the water is twice strained before entering the 27-inch main to the town. At the rear of the wet well is a rectangular dry well thirty feet in length by eighteen feet in breadth, in which is la d the 27-inch main that conveys the water to the town and which bifurcates into the two branches which receives the water from the well, each branch being furnished with a 27-inch sluice valve.
