Lower Trent Erewash
The Lower Trent and Erewash management catchment is one of the largest and most varied river systems in the region. Stretching from the confluence of the River Dove and River Trent near Derby to Alkborough Flats on the Humber Estuary, it covers around 2,045 km² and includes major rivers such as the Trent, Derwent, Soar, Erewash and Idle. The catchment spans Nottinghamshire and parts of Derbyshire, Leicestershire, Lincolnshire, South Yorkshire and North Lincolnshire, creating a highly interconnected landscape.
The area is made up of numerous waterbodies, ranging from urban waterways to rural tributaries and wetlands. This diverse network supports agriculture, industry, urban water management and important ecological corridors, but also brings a wide range of environmental pressures.
For our Environmental Destination (ED) programme, we are focusing on a specific “area of interest” within the catchment, relevant to our abstractions. Our focus is those surface water bodies where we actively abstract water or where our groundwater abstraction impacts on flow to surface waterbodies. The primary focus of Severn Trent’s investigation will be the Nottinghamshire South A and Nottingham Urban Operational catchments due to location of Severn Trent’s abstractions and the connectivity with the Permo-Triassic sandstone aquifers from which public water supply water is abstracted.
Please note the correct WFD management catchment name for this catchment is ‘Trent Lower and Erewash’, we are referring to it as the Lower Trent and Erewash as this is how it is commonly referred to and this is the name used for the catchment by the Environment Agency.
We need your help!
Your involvement is crucial as we work together to better understand the Dove. We will be conducting a workshop on 21 May 2026 at Horsley Village Hall, Horsley, DE21 5BR. We hope you can attend and bring your local knowledge, practical experience, and on‑the‑ground perspective that we simply can’t capture through data alone. Together we hope we can build an accurate picture of the catchment, help identify viable water resource options, highlight potential opportunities to improve in-river ecology and shape partnership projects that genuinely reflect local priorities. Your input ensures that the plans we develop are realistic, collaborative, and capable of delivering real improvements for the water environment. Ultimately, by working closely with us now, you’ll be helping to secure healthier rivers, more resilient catchments, and better outcomes for the communities and sectors that depend on them.

What are our objectives and investigations?
Understand what river flow targets and changes to water abstraction may be needed to support a healthy water environment in the Lower Trent Erewash.
Check how well the Environment Agency’s national modelling reflects local conditions. You can view their modelling in the Modelled Abstraction Reductions – National Framework for Water Resources 2025.
Compare the national modelling with improved local data to make sure we’re getting an accurate picture of the catchment and its needs.
Explore options to improve and protect river flows, including reducing our own abstractions where necessary. We’ll also look for opportunities to work with local partners and develop Nature‑Based Solutions (NBS) that strengthen the catchment’s resilience.
Use the evidence gathered to build confidence in any future abstraction changes, helping us prioritise actions and plan a realistic timeline for making improvements.
Feed into the development of our Water Resources Management Plan (WRMP), which outlines how we will meet long‑term challenges such as population growth, drought, environmental pressures and climate change, while ensuring a reliable water supply. The plan is being developed alongside the Water Resources West Regional Plan, which sets out how all abstractors in the region will work together to secure water supplies over the next 60 years. The first plan was published in June 2025 and is available here: Water Resources West Final Regional Plan — Water Resources West.
So who abstracts water and how much?
In the Lower Trent and Erewash catchment Severn Trent has licences which total 69Ml/d licenced for Public Water Supply abstraction from groundwater. Severn Trent has already committed to sustainability reductions totalling 3.8 Ml/d below Recent Actual abstraction rates across two abstraction sources in the catchment, which will come into effect in 2030.
Severn Trent also have surface water abstractions from the River Trent and two reservoirs; these are outside of the area of interest for this investigation as they already have conditions on them which protect the environmental flows in the rivers.
Anglian Water also operates public water supply abstractions from the Lower Trent and Erewash catchment, but they are further downstream in the Trent and Tribs Operational Catchment so not in the area of interest for Severn Trent’s investigation.
The data below istaken from Modelled Abstraction Reductions - National Framework for Water Resources 2025 . Note that these figures cover the whole of the Lower Trent and Erewash, not just the area of interest for this investigation and cover both surface water abstraction and groundwater abstraction.
What have we done so far and what have we got planned for this investigation?
We are working to a deadline of 31 December 2026 to deliver the first phase of Environmental Destination investigations. By this date we will have developed abstraction reduction scenarios, compiled a high-level list of potential options which enable the proposed reductions or support the ecological needs of the catchment and we will deliver a narrative of how we have come to our decisions.
During 2025:
WRW water companies have been working together and with regulators to agree the scope and methods for these investigations.
We have been analysing data and previous investigations to develop an understanding of the catchments and understand current flow pressures and impacts on ecology.
During 2026:
We will be holding engagement sessions to talk to other abstractors, water users and stakeholders to develop our understanding of the catchment and pressures on water. We will be looking for opportunities to get involved in existing projects and work with you to develop new opportunities to improve water resources and low flow conditions in the catchment. Once confirmed the sessions will be listed here along with a booking form. In the meantime, you can register your interest by providing your contact details below.
We will be undertaking modelling work to enhance the understanding of the catchment, look forwards at the potential impacts under one or more climate change scenarios. Along with information collated from stakeholders we will assess the EAs national framework reduction numbers to identify what reductions may be needed in the future to public water supply abstractions.
We will begin to prioritise the actions that are needed and develop an approach through the WRMP and regional plan to address these.
