Revised Standard from Last Update.

1 SCOPE

1.1 This standard (Part 1) lays down general requirements for the design and construction of plain, reinforced or pre-stressed concrete structures, intended for storage or retaining of aqueous liquids. A concrete structure or member may function as liquid retaining, when the amount of liquid permeating through its thickness, under hydraulic gradient, is practically negligible.

The recommendations are generally applicable to the storage/retaining of aqueous liquids having temperature not exceeding 50 °C and no detrimental action on concrete and steel or where sufficient precautions have been taken to ensure protection of concrete and steel from damage due to action of such liquids.

The requirements applicable specifically to plain and reinforced concrete and pre-stressed concrete liquid retaining structures are covered in IS 3370 (Part 2), and IS 3370 (Part 3), respectively.

1.2 This standard does not cover the requirements for concrete structures for storage/retaining of hot liquids, hazardous materials and liquids of low viscosity and high penetrating power such as petrol, diesel and oil. This standard also does not cover dams, pipes, pipelines, tunnels and damp proofing of basements.

This standard does not cover all the requirements of pressurised tanks, floating structures and tanks having the additional requirement of gas tightness. The selection and design of coatings and linings are not covered in this standard.

1.3 The criteria for design of RCC staging for overhead water tanks are given in IS 11682.
