The EA draw upon the CatchIS system, running the CatchIS software together with a range of additional specialist modules, benefitting from the modular design of CatchIS.

The Voluntary Initiative

Stakeholder group

The Voluntary Initiative (VI) undertook a review of CatchIS in the Ugie catchment, Scotland, producing and validating a surface water risk assessment map for the pesticide IPU showing the spatial patterns of risk due to the pesticide properties, soil and climate.

The Catchment Sensitive Farming Initiative

Industry advisers and extension

The Catchment Sensitive Farming Initiative (CSFI) programme have received a series of reports for a number of the initial CSF catchments showing maps of risk due to the soil and climate only. Workshops and discussions have been held with the relevant CSF Officers to aid the interpretation and application of these results.

United Utilities


United Utilities have been using catchment reports from the CatchIS bureau service, showing the top pesticides for each of their water treatment works split between surface water and ground waters.

Anglian Water


Anglian Water are receiving regular CatchIS bureau reports to aid their determination of catchment risks to surface and groundwaters, as well as supporting their sampling strategies.
