i think , because water tanks are more vulnerable structures and plus the tank is sometime overfilled and sometime empty, the pressure inside is so varying,
its needs more safety precautions and as we all know working stress method assumes more safety factor than limit state design, which is an economical design, we prefer to use working stress method...
Yes we can use limit state design for water tank design....
The main difference between the old and new code is the method of design-earlier one is based on Working stress method and the present one is based on Limit states Design! Hence comparisons are difficult to make. Since you are conversant with IS 456, it may not be difficult for you to follow. I do not have the new codes here-I saw the Draft- but think that the tables for BM calculation remain the same. You have to use LSM equations for the design instead of WSM. Note that crack control is imp. in such structures. Hence the code prescribes Clauses for the same.
There are the physical size of the filtration. Then there is the ion exchange method. And then there is the absorption phase.
Yes, even it is not working, water will still run through it.Yes, even it is not working, water will still run through it.

The methods depend based on the type of structures. for eg. for water Retaining structures the Working stress method gives good life and for other structures which is not exposed to water, mostly limit state design works.

Effective Stress at Ground Water Table = Total Stress minus the Pore water stress, but the pore water stress is negative, therefore = Total Stress plus the water pressure in capillary zone. -kelvinbrbTSU

People who suffer from joint damage may find it difficult to exercise due to the strain and stress on their joints. Swimming workouts can be a viable alternative to walking or jogging because the water reduces stress on joints. Fibromyalgia and rheumatoid arthritis patients can especially benefit from working out in the water. Pregnant women will also find water workouts enjoyable because they allow for greater movement and less stress on the body, but give you a good workout.
Effective Stress is the grain to grain contact of soil particles. the higher the effective stress, the stronger the soil. effective stress at a certain depth is calculated as follows: Effective stress = total stress - pore water pressure the pore water pressure is often taken as water table. pore water pressure has a negative effectice on effective stress, as it hinders grain to grain contact.
