New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 1) which is identical with ISO 24516-1 : 2016 ‘Guidelines for the management of assets of water supply and wastewater systems - Part 1: Drinking water distribution networks’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Environment Protection Sectional Committee and approved by the Chemical Division Council. Drinking water utilities are reliant on their assets to deliver their services to the resident populations in their jurisdictions. The assets (underground pipes, reservoirs, storage tanks, treatment plants, etc.) collectively form the physical infrastructure of the drinking water utilities and are the consequence of the accumulated capital investments and operational expenditures on maintenance and rehabilitation over many years. Considering the importance to develop standard for providing guidelines on management of assets of drinking water networks to maintain value from existing assets and to follow the uniform practices globally, the Committee felt that it would be more convenient to prepare this standard by adoption of ISO 24516-1 on dual numbering system.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appears referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
