Dataset
Gridded actual groundwater, surface water and tidal water abstraction, discharge and Hands-off Flow datasets for England (1999 to 2014)
Abstract
This dataset contains recorded or ‘actual’ abstraction and discharge data for sites across England that have been transformed into 1 km × 1 km resolution gridded data along with surface water Hands-off Flow (HoF) conditions, and are available in CSV and/or NetCDF formats. It includes:
(i) Monthly abstractions (m3 month-1) from 1999 to 2014 for each source (Groundwater, Surface Water or Tidal Water)
(ii) Mean monthly abstractions (m3 month-1) over the period 2010 to 2014 for each source (Groundwater, Surface Water or Tidal Water)
(iii) Daily rate of Consented Dry Weather flow (CDWF)and Recent Actual (RACT) discharges (m3 day-1) based on information from a 6-year period ending in 2017
(iv) Hands-off Flow (HoF) conditions (m3 day-1) for 2022
Further details, including caveats about usage, are provided in the linked Data Document.
These data were sourced from the Environment Agency (EA) monthly groundwater, surface water and tidal water abstraction data from 1999 to 2014, and annual discharges and surface water Hands-off Flow (HoF) conditions were obtained from the EA’s Water Resources Geographic Information System (WRGIS 2017 and 2022 versions respectively).
This data publication is supported by the Natural Environment Research Council award number NE/X019063/1 as part of the Hydro-JULES programme delivering National Capability. The dataset is also linked with the Climate Services for a Net Zero Resilient World (CS-N0W) project.

| Data lineage: |
The abstraction and discharge datasets were sourced from the Environment Agency. Specifically, monthly groundwater, surface water and tidal water abstraction data were obtained from 1999 to 2014, and annual discharges and surface water Hands-off Flow (HoF) conditions were obtained from the EA’s Water Resources Geographic Information System (WRGIS 2017 and 2022 versions respectively). Due to national security data restrictions regarding the location of public water supply abstractions, publication of the dataset is limited to a 1 km x 1 km resolution. Information at a higher resolution has been removed or converted to a 1 km x 1 km resolution as appropriate, and any personal or identifying data has been removed. These data were compiled by the project team before archival at EDS-CEDA |
| Data Quality: |
The datasets consist of files of the spatial distributions of 1 km × 1 km resolution groundwater (GW), surface water (SW) and tidal water (TW) points actively abstracting at any period during the years between 1999 and 2014, a 5-year mean from 2010 to 2014, and active discharges during 2017, together with the locations of Hands-off Flow (HoF) conditions in 2022.
The gridded NetCDF file data are provided for England only: this is a 601 km × 660 km spatial domain on the British National Grid from the lower left corner (55000, 0) to the top right (656000, 660000) metres. The England region was delineated using the Local Authority Districts Boundaries UK BFC shapefile (December 2023: www.data.gov.uk).
