# How to find Sump/Tank capacity ?

How to find Sump/Tank capacity OR How many liters can be stored in your tank/sump?

1. To find out your sump capacity first you need to have length, width and depth of  your sump/tank in feet
2. Multiply length, width and depth of your sump to find out cubic area of your tank/sump.
3. 1 feet cube area(1′ length * 1′ width * 1′ height) will store upto 28 ltrs of water.
4. So multiply your sump cubic area with 28 and you will get your sump/tank water storage capacity in liters
5. Above formula will work only if your tank shape is in rectangle or square.
6. If at all there are different shapes then find out total area in cubic feet and  multiply with 28 which will result number of liters
• Water pressure will be more on the edges of the tank. So avoid constructing sump/tank corners with 90 degrees like room walls.
• When you are constructing  sump, have edges in a curved shape. so that water pressure will be diverted to a larger area. This will have some significant effect in the long run.
• While constructing sump, Manson will use iron mesh during plastering to avoid cracks.
• Sump and tank plastering should be completed at one stretch to avoid cracks.
• Do not use low quality brick for sumps and tanks.
• Keep sump door always towards street side. so that tankers can pour water easily
• Keep 3″ pipe connection to the sump from outside. So that water tankers can directly pour water from outside
