  • Bureau of Indian Standards (BIS) has prepared a draft standard for the supply system of piped drinking water.
  • The draft is named as Drinking water supply quality management system requirements for piped drinking water supply service.
  • The draft has been developed keeping in view the Centre’s Jal Jeevan Mission for providing safe and adequate drinking water to all rural households by 2024 through tap connections.
  • IS10500 - It states that the drinking water after treatment should conform to the Indian Standard (IS) 10500 developed by the BIS.
  • The IS 10500 outlines the acceptable limit of substances such as heavy metals, other parameters like the pH value of water, its turbidity, the total dissolved solids in it, and the color and odor.
  • District Metering Area - It is a concept for controlling leakages in the water network in which flow meters are installed to detect leaks.
  • Water Sampling –Water should be sampled at the treatment plant every 4 hours, at the water reservoirs for every 8 hours and random sampling at household levels.
  • Water Audit - It is a calculation of the amount of water put into distribution against the amount that is consumed and it should be conducted on a quarterly basis.
