A little job I've been working on recently, an emergency water supply tank for a fire training ground at a remote location.
The tank is 1.4m dia and around 1.8m high, 2500 litres capacity, my brief was to fit a sight tube for water level and the outlet fittings, and mount a filling hose, the only fitting on it is a plastic 2"bsp threaded outlet at the base,
I reckon the fewer holes the better in these kind of jobs so came up with a way of doing it using the existing fitting.
A threaded tee modified by welding a concentric reducer and a hose tail to fit the bottom of the sight tube, the clear tube is a length of 38 ID x 47 OD PVC,
To protect it and keep it straight I cut a long slot to make a window in a length of 2" stainless tube and slipped it over the top. the clear tube also has a stainless vented cap and a plastic float in it. to prevent the float from dropping into the valve there is a bar welded across inside the hose tail.
The whole thing is supported by a simple cage from 50 x 3 stainless flat bands, and 40 x 20 box section for the uprights, standard pipe clamps
welded on to the frame support the over tube and the filler, the filler tube was made up using a 2 1/2" dairy bend welded to a mounting plate and fitted to that convenient flat section at the top, the green tube is a free issue part from the customer
This will be filled from a fire engine pump, although there is a vent built into the centre section of the lid I was concerned that a pump on full bore would put water in faster then the air can get out, visions of a blown up tank or a lid taking off like a flying saucer come to mind, so an extra vent was fitted to the lid
The thing is mounted on a plinth and is almost complete here, just waiting for a fitting to complete the outlet.
