Reducing water treatment costs for Scottish Water

The Problem

With over 230 water treatment works supplied with water from over 400 catchments, Scottish Water have an ongoing challenge to improve water quality upstream in order to reduce the rising operational cost of treatment downstream. 12,000km2, approximately 50% of the catchments are peatland or consist of soils with a high organic matter content.

The Solution

Following extensive mapping and assessment of peatland data covering 10,200km2 of Scottish Water catchments, Rezatec derived a peatland integrity index and water quality risk information layer from multiple sources of aggregated data.

To enable more pro-active peatland and catchment management in general, the data sets were enhanced with unique algorithmic predictive modelling. Then an interactive data visualisation and interrogation service was developed containing a comprehensive set of satellite-derived data products depicting ecosystem integrity, land use and environmental risk for the entire set of Scottish Water’s catchments across all peat soils.

The Outcome

Rezatec’s platform and customised peatland data product allows Scottish Water to view problematic areas of peatland degradation or areas at risk of water pollution from DOC using several different data layers.

Detection of risk areas means that ground teams can now be deployed more efficiently to cover vast and difficult terrain and to carry out restoration efforts more effectively. In turn, this will help improve peatland integrity and reduce DOC pollution.

Overall, the operational cost of mapping, assessing and monitoring peatlands is also reduced.
