Environmental Impact


The water sector has committed to being operationally net zero by 2030 and non-household customers have a part to play. However, we can’t change what we don’t measure consistently. The Greenhouse Gas Emission dashboard will help trading parties understand the emissions from water and sewerage treatment in the non-household market. Please note that you must be logged in to view this dashboard.


Water Efficiency

The water efficiency dashboard and maps support our Data Insight improvement programme and the (RWG) Water Efficiency Action Plan Headline Action 2: 'Better use and smarter sharing of data'. Sharing this enriched data centrally with the market will support collaboration between wholesalers, retailers and the water resource regional groups by providing greater visibility of national non-household demand. This will in turn improve our understanding of how to best support customers in reducing water wastage and forecasting demand.

Water Efficiency Dashboard

The water efficiency dashboard enables users to interactively filter non-household supply point identifiers (SPIDs) and consumption by different organisations, geographic contexts and industry types.  The dashboard can be accessed below, as well as via the Market Charts section:


Map views to support Water Efficiency

The interactive Water Efficiency maps below show the collated national geographical boundaries relating to the management of water resources. Bringing together three levels of detail, regional, area and zonal, they provide a high level national reference designed to be used in conjunction with the Water Efficiency dashboard.

Water Scarcity by Postal Sector

Searchable map combining various different stress metrics to give a view of water stress by postal sector.


Water Resource Planning Regions

Names and boundaries of the six regional water efficiency groups.


Water Stress Areas

Names, boundaries and designations of the 23 water company-based Water Stress Areas in England.


Water Resource Zones

Names, boundaries and water deficit categorisations of the 138 Water Resource Zones (WRZs) in England and Wales.

These products use CMOS data that has been enriched with data from several additional sources, including water resource 2019 submissions from water companies, Environment Agency’s 2021 water stress designations, MOSL's industry type categorisation and annual water company operational carbon emissions.
