Dear Sir,
A room and the roof is RCC slab were built 12 years back with 4 inch wall on all side. on the second floor of my house.
The area of the slab is 54 Square feet roughly
Two adjacent four inch walls rest on a 9 inch wall till ground( in L shape).

The ground floor building is 40 year old with no pillar construction only supported by 6 layer foundation and the first floor is 25 year old walls.
Above this rooms RCC slab (built 12 years back and suporting 1500 liters of water tank till date) now i have placed a 5000 liter water tank. i.e. Sintex Double layered 5000 litre Overhead tank for my house. The filled water tank weight could come upto 5100KG (assuming density of water @997Kg per cubic meter.

Will the structure explained above withstand this STATIC loading from the 5000 liter water tank or should I reinforce with some steel structures. Please offer your expert comments.
