IS 3370 (Concrete Structures for Storage of Liquids — Parts 1–4): Governs design of water tanks, swimming pools, reservoirs, and liquid-retaining structures. Key requirement: concrete must be crack-free (tension crack width < 0.1–0.2 mm) to prevent leakage. Uses WSM (working stress method) with reduced permissible stresses. Min reinforcement ratios higher than IS 456.
