The Ramloste taub under the berandah of the wash-house to be 15 feet long 5 feet deep and 9 feet wide : to be built in accordance with the description hereinafter specified for the roofs and floors. The thickness of the side walls will depend upon the nature of the soil in which it is excavated : if in rock of fairly uniform character, little more than a watertight facing will be required ; in any case 9 inches brickwork laid in cement and sand 1:2" will be amply sufficient : the top of the tank may be formed of a solid slab of concrete 6" thick which will also serve as the level floor of the berandah. A manhole for access to the tank to be formed in the top, with stone covering slab, fitted with a flushing grating and ventilating shaft, and in the bottom of the tank a shallow wash out well should be provided for cleaning purposes. Great care must be taken not to connect the overflow pipe of this tank with any part of the foul drainage system.
4. Manholes and ventilating traps to drains. At the points shown by small rectangles in plan and at such other points as may appear necessary, manholes will be formed on the lines of drain for the purposes of inspection, flushing and ventilation.
