Retail market operator MOSL has published a new version of the publicly available water efficiency dashboard. The latest version uses official Ofwat Water Resource Zone (WRZ) data and newly enriched market data at a supply point (SPID) level, as opposed to meter level, as the dashboard did previously.
This means 99% of water and sewerage SPIDs are now matched to a WRZ, allowing wider visibility of SPIDs in high water deficit and drought restriction zones. MOSL said this insight will enable improved collaboration between wholesalers, retailers and regional water resources management groups to support the delivery of non-household demand reduction targets.
The building blocks of the water industry, WRZs define the geographical areas used by water companies to forecast long and short term supply and demand balances. The boundaries also define the areas if drought restrictions are brought into force and other environmental data such as water deficits.
Previously, the smallest geographical area that MOSL could categorise SPIDs by was wholesaler region - WRZs are not data items in the market data warehouse. However, wholesalers can have multiple WRZs within their region, each with potentially very different characteristics - for example, water scarcity may vary between WRZs within a region.
MOSL solution links SPIDs with WRZ they are located in
To rectify the problem and unlock the potential of WRZs in understanding environmental data, like high water deficits and drought restrictions, MOSL has enriched the data by linking all market SPIDs with the WRZ they are located in.
SPID ‘point’ location is derived using standard logic that first uses water meter coordinates. If it is unmetered, the Unique Property Reference Number (UPRN) on the primary SPID is used and, if this is not present, we use the central point of the primary SPID’s postal sector.
Every month, MOSL validates new and updated location data on SPIDs and meters to ensure they are enriched and remain up to date. The enriched data is fed into the MOSL’s data warehouse and linked to further WRZ based lookup data (eg. drought restrictions and water deficits).
Dashboard shows 60% of NHH water consumption is in regions classified by the EA as seriously water stressed
What does the dashboard show?
- 36% of non-household supply points are in water resource zones with high water deficits
- 33% of non-household water consumption are in these areas with high water deficits
- 60% of NHH water consumption is in regions classified by the EA as seriously water stressed
The enriched market data is now being used on a variety of data services including the Water Efficiency dashboard, the Large Supply Point dashboard and the Drought Restriction dashboard.
