Water trading (‘Bulk supplies’) register 2018-19

A bulk supply is a supply of water from one appointed company to another. Bulk supplies are sometimes referred to as ‘water trades’ as they are a way for water companies to trade water. Transporting the bulk supply from one company to another company involves an ‘interconnection’, often in the form of a pipe. Companies can draw up a contract between them (a ‘bulk supply agreement’) that sets out the terms and conditions of a bulk supply, including the price.

Water trading can have economic and environmental benefits, by providing alternative sources of supply that may have lower costs or lower environmental impact. To encourage trading to happen we publish information from companies about their bulk supplies. You can find this information for 2018-19 below.
