Please note: The information contained in this chapter sets out good practice that should be considered by event organisers. However, it is industry guidance and does not necessarily cover everything that organisers need to consider for a particular event.
There are regulations covering the quality of water supplied for domestic purposes, which includes for water (potable)used for drinking, washing, cooking and sanitary purposes. Connecting a main or service pipe (including hosepipes) to a water company’s network, by someone other than a water company, is prohibited under the Water Industry Act 1991. If a running water supply is needed, it is important to contact the local mains water supplier for advice. If using a private water supply, this must not be brought into use or used until the local authority is satisfied that the supply does not pose a potential danger to health risk.
