Water Resources Market Information
In line with Ofwat’s Water Resources Market Information guidance, alongside our final Water Resources Management Plan 2019, we published data tables for each of our Water Resource Zones (see downloadable content below).

This would enable third parties, who can either be other incumbents or independent third parties, to identify opportunities to provide new water resources; and identify and provide demand management and leakage services. Each spreadsheet contains key market information as well as the WRZ’s water resources position as detailed in our final Water Resources Management Plan 2019.


Northumbrian Water has two Water Resource Zones, namely Kielder and Berwick.


Essex & Suffolk Water has four Water Resource Zones, namely Essex, Blyth, Hartismere and Northern Central.


Our WRMP19 forecast that we had a supply surplus across the full planning period in all of our WRZs.


We are now preparing our draft Water Resources Management Plan 2024 and are forecasting a supply surplus in our Kielder and Berwick & Fowberry WRZs.


However, we are forecasting supply deficits between 2025 and 2050 in our Essex, Hartismere, Blyth and Northern Central WRZ’s in our Essex & Suffolk Water region as follows:


Essex:               ~26Ml/d

Hartismere:     ~7.5Ml/d

Blyth:                 ~2.5Ml/d


We are currently forecasting a supply surplus in our Northern Central water resource zone in Suffolk.  However, depending on the outcome of AMP7 Water Industry National Environment Programme Investigations, sustainability reductions might be applied to key abstraction licences which could cause a supply deficit.


Consequently, as part of WRMP24, we are considering new demand management and supply options and would welcome discussions with any party who could contribute towards meeting that requirement.


The above numbers will be revised as we finalise our:

  • AMP7 Water Industry National Environment Programme Investigations (these will confirm the sustainable level of abstraction for each of our groundwater abstraction licences); and
  • PR24 baseline supply and demand forecasts.

The data can also be viewed using Watersource, an online platform that we have jointly developed with Wheatley Solutions and Anglian Water. This is a new concept to provide access to key elements of the Market Information through a central ‘open’ cloud portal. Users can identify spatially those areas (Water Resource Zones) which have a supply surplus and those areas which have a supply deficit. The Watersource platform can be accessed at wheatleywatersource.co.uk.
