# How to find out the quantity of water in a sump/tank

In this construction article, you will learn the detailed process for determining the capacity of Sump/Tank or the quantity of water to be preserved in the tank/sump.

For this purpose, initially, one should require length, width and depth of your sump/tank in feet.

Now, multiply the length, width and depth of the sump to determine cubic area of your tank/sump.

1 feet cube area (1' length 1' width 1' height) will preserve equal to 28 ltrs of water.

Therefore, multiply the sump cubic area with 28 to find out the water storage capacity of sump/tank in liters.

Above formula is applicable if your tank appear as rectangle or square in shape.

If at all there are different shapes then find out total area in cubic feet and multiply with 28 which will produce number of liters.

Water pressure is higher on the edges of the tank. So, it is recommended not to build up the corners of sump/tank at 90 degrees angle similar to room walls.

While developing sump, all the edges should remain in a curved shape in order to disperse water pressure to a bigger area. It will provide some vital impact in the long run.

When sump is built up, iron mesh is applied in manson throughout plastering to resist cracks.

The plastering work for sump and tank should be finished at one span to get rid of cracks.

It is recommended not to utilize low quality brick for sumps and tanks.

The sump door should be located towards street side in order that tankers can pour water smoothly.

Maintain 3?pipe connection to the sump from exterior to facilitate water tankers to directly pour water from exterior.
