Rezatec is deploying its landscape intelligence portal platform to work with Bristol Water on a ground-breaking project designed to gain a deeper understanding of the impact changing agricultural land use and soil erosion has on water quality in its catchment area.
The initiative has a particular focus on changing land use in the Blagdon Reservoir and Chew Valley Reservoir catchments. Rezatec’s portal based analytics process satellite and ground data to identify changing patterns of soil erosion and agricultural intensification, which have a significant impact on the quality of the water supply. The Rezatec landscape intelligence platform performs a forty year look back and processes data from 1972 to the present day so as to identify both short and long term changes in the landscape.
Landscape factors, such as agricultural practices related to specific crop types, can have a significant bearing on water treatment costs. Diffuse pollution associated with fertilisers and pesticides applied during the crop growth cycle can make its way into upstream water catchments through runoff and soil erosion, necessitating its removal downstream through expensive treatment so as to maintain the quality of the overall water supply. It is hoped that by identifying potential pollution risks before they become an issue, ongoing water treatment costs and the frequency of acute pollution events can be reduced, and requirements to invest in new water treatment infrastructure will be delayed or even avoided.
Matthew Pitts, Environmental Programme Delivery Manager for Bristol Water, said: “This new and exciting way of understanding our water catchments promises to bring valuable insights into how we can enhance the environment and manage risks to water treatment and supply.”
He added: “Using innovative, cutting-edge landscape analytics, we’re confident that we can gain a better understanding of the potential pollution risks within our catchment. This will help us to focus efforts towards achieving improved water quality in our reservoirs, bringing ecological benefits, reduced treatment costs and ultimately better value for our customers.”
Rezatec’s Philip Briscoe commented: “From our analysis of different sources of Earth, airborne and ground data, we derive high-value data products which provide our customers with business insight on a macro and micro scale. We’re delighted to be providing Bristol Water with landscape intelligence that helps them to make better business decisions to derive tangible benefits for both the company and its customers.”
The data products are accessible on a subscription basis to clients through Rezatec’s landscape intelligence portal that allows water companies to view detailed environmental information about their catchment areas, ultimately supporting informed business decisions. Rezatec analytics help manage risk to the water supply by monitoring changes to agricultural land use and peat and soil integrity at a local and regional scale.
As well as Bristol Water, Rezatec is bringing similar insights to other water companies and looks set to benefit many more in the coming months.
