Water & Catchment Management

With internationally recognised experts in water and catchment management we have detailed understanding of current and emerging legislation and policy mechanisms that influence how our landscapes are managed. This technical knowledge is uniquely combined with practical on the ground experience that enables us to support clients in all aspects of catchment management.


Key Projects

Natural England – Catchment Risk Assessmentwrlcrane

Westcountry Rivers Limited are delivering 8 catchment risk assessments across diverse freshwater Sites of Scientific Interest (SSSI) and Special are of Conservation (SAC) catchments which are failing to meet their water quality objectives. The aim of these assessments is to follow a weight of evidence approach to characterise pollution risk in the catchment and provide a targeted intervention strategy with suggestions for improving water quality in the designated site. We work in partnership with Natural England and other local stakeholders including Catchment Based Approach hosts to ground-truth modelled outputs and present the evidence so it is more accessible and therefore better able to inform the delivery of future catchment management initiatives.


South West Water: Catchment Investigations

ESP staff are delivering 17 catchment investigations across the South West to inform the business plan for the next Pricing Review.  The approach involves a mixture of land-use monitoring, modelling and farm surveys, which are used to refine multiple parameter export coefficient models.  The final output provides a detailed plan, including costs to achieve more consistent raw water quality standards for abstraction to help inform PR14.

Environment Agency: Willingness To Pay, Environmental Benefits Assessment

In this project ESP staff successfully developed a conceptual framework and methodology to link WFD classification and reasons for failure data with disaggregated WTP values. The framework will enable the Environment Agency to assess the WTP for different suites of measures and prioritise measures which will realise the greatest environmental benefit.

UKWIR – RG08:  Disproportionate cost analysis and cost-effectiveness of measures in other sectors

ESP staff are working with Atkins to assess the cost and effectiveness of measures to reduce nutrient concentrations / loads in failing waterbodies across England and Wales. ESP have undertaken a national source apportionment modelling exercise to assess the effectiveness of nutrient stripping at wastewater treatment works in reducing concentrations to achieve WFD status. These have then been compared with catchment management options for a variety of different mechanisms used to tackle diffuse water pollution from agriculture in order to provide a strategic assessment of the most suitable option in different catchments.
