FOREWORD

This Indian Standard (Fourth Revision) was adopted by the Bureau of Indian Standards, after the draft finalized by the Water Supply and Sanitation in Building Sectional Committee had been approved by the Civil Engineering Division Council.

This Indian Standard was first published in 1957 and subsequently revised in 1963, 1971 and 1983. In this revision, requirements of water supply for residences has been listed based on population of the community. However, for Lower Income Group (LIG) and Economical Weaker Section of Society (EWS), the value of minimum requirement of water supply has been retained as 135 litres per head per day. Fire demand in buildings has been catered to, by giving reference to a suitable standard.

This code represents a standard of good practice and, therefore, takes the form of recommendations.

(Fourth Revision)

1 SCOPE

1.1

This standard lays down basic requirements for water supply, drainage and sanitation for residential, commercial, industrial and other types of buildings in urban areas including railway platforms, bus stations and terminals, seaports, airports and market yards.

1.2

This standard does not take into consideration the requirements of water for industrial plants and processes which have to be provided for separately depending upon individual requirements. It also does not take into account overcrowding, both casual and permanent, and is based on the assumption that the average size of a family is 5, and 9 m2 floor area is occupied by not more than two persons. It does not provide for municipal water supply requirements such as for street cleaning, etc.
