Water storage

Storing water has two main purposes,

  1. To provide for an interruption in supply.
  2. To provide suffi cient volume to cover peak demands.

Design codes recommend that storage is provided to cover the interruption of an incoming mains supply, in order to maintain a water supply to the building.

Water supply companies are empowered to insist on specifi c terms including the volume or period of storage, within the terms of their supply agreement with a consumer, however many water supply companies only recommend that storage be provided in accordance with BS6700, placing the responsibility and decision fi rmly on the consumer.

The table below provides guidance on typical usage within a building over a 24 hour period.

The table also provides storage volume based on the % of daily demand when the water supply company or client has not dictated the period of cover.

Consideration should also be given to ensure that the break tank has suffi cient volume to cover 50% of the design duty for a minimum duration of 10 minutes.
