Mains pipework

Mains injection and pipework chlorination

A mains injection or pipework chlorination is disinfecting and pre-commissioning the hot and cold domestic water supplies connecting to the mains. This connection extends to a building's internal hot and cold domestic system.

Which type of water supply are you working with?

Internal Water Supply

The building's internal hot and cold domestic system is an internal water supply, including all pipework and storage tanks. This process ensures safe potable water to water outlets such as showers and taps. 

External / New mains Water Supply

Suppose you are installing a new water mains supply to a site. In that case, there is a legal requirement by the local water authority for the pipework to be flushed and disinfected to the water authority's specification.

The relevant water authority will not approve your mains connection unless a mains chlorination is conducted with an appropriate provider. Once this is done, you will be provided with a certificate that acts as a green light to be connected. This is in place to prevent contamination of the water supply.

Industry Standards

The recognised standard for undertaking mains chlorination work is BS 8558:2015 (and Guide PD855468:2015) alongside any additional requirements of specific water authorities.
