Cold Water Storage

This chapter provides guidance for the installation and maintenance of cisterns storing mains supplied cold water which is intended to be used for drinking, washing or bathing or other purposes requiring wholesome water.

A cold water storage cistern may be installed for various reasons including:

  1. To provide backflow protection
  2. To provide a reserve supply in the event of any disruption to the incoming cold water supply
  3. To reduce the maximum demand on the cold water supply
  4. To reduce the supply pressure
