Underground water storage tank problem
- Dear All,
Can some one tell me the solution of following problem:
I want to contruct an underground water strorage tank which will receive water from canal for drinking purpose because the groundwater of that area is brackish (project area is sindh, Pakistan). The dimension of tank is 22 x 22 x 6 cft. The tank is brick masonry. But during excavation underground saline water appear at a depth of 3 ft. So now what should I do, what material in foundation and at side walls I should use so that the structure remain economical and strong enough.
