Project summary

Edit project overview to modify the project summary.

Over 250 years of industrial activity and regeneration have heavily modified Telford’s urban catchments. Under the Water Framework Directive assessments the Lydebrook and Madebrook catchments are failing. Macroinvertebrates communities are fragmented and prone to local extinctions. The watercourses are overloaded with urban diffuse pollution via misconnections, road run off and the legacy of the townships industrial past. Water is a fundamental part of the green infrastructure of urban Telford , Shropshire Wildlife Trust have been championing the positive care of Telford’s green network for decades and now the two come together in the catchment based approach to urban diffuse pollution. In close partnership with Telford and Wrekin Council, Severn Trent Water, Severn Gorge Countryside Trust, local community groups and with the support of the Environment Agency we are working to lift the fortunes of the two catchments. Description of Works The Lydebrook catchment has been massively disrupted by industrial activity. Where we can get access to the water we are planning to install new aquatic vegetation to help self-clean the water, work on riverside trees and hedges to reduce sedimentation from erosion and improve ground cover. Hedge laying has been used to address erosion, pre-planted coir rolls utilised to create new wetland edge to provide habitat and water cleansing capacity to the series of balancing pools and channels. The interventions are targeted at three balancing pools and short stretches of stream channel. In the headwaters area we shall be investigating the potential of a SuDS system to treat road-off. On the Madebrook catchment we are designing and installing four new rock cascades to improve oxygenation and ecological connectivity. Over 400m of de-culverted watercourse will be created through the Madebrook and Stirchley Dingle proposed Local Nature Reserve. The new watercourse will be allowed to naturally re-vegetate and strengthen the isolated aquatic community found on this section of the much modified water course. The new channel will include features to encourage educational access, promote stream dynamics and enhance invertebrate populations. We are also working with Telford Angles Association to improve disable angling access. We will be promoting the Retro fitting of SuDS in urban Telford in a number of ways. Working with RICOH ltd we aim to have a small scale SuDS feature fitted, we are exploring SuDS feasibility at the Halesfield Industrial Estate via a PhD research project and we are working with the BESST network via their seminar programme to promote wise water management to their members. Volunteers are integral to the Trust approach and the CRF project will see volunteers leading the sampling and monitoring and carrying out small scale remedial works throughout both catchments. Our Education Team are developing a ‘River Rangers’ school resource which is being trialled through two schools (one per catchment). The schools scheme includes exploring their local water course, conducting a school water audit and finally designing and with our support constructing their own rain garden or other SuDs feature. All the community consultation in regard to the engineering works is being supported by more general community events to promote and engage local residents in the care of the rivers and streams in their neighbourhood.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.

Monitoring of public responses to the project has shown good support and understanding of the reasons for the works. Volunteer engagement has been of a high quality and helped immensely in realising the broader aims of the project.

Fixed point photography has demonstrated the quick recovery rate of new earthworks and features.

Aquatic and chemical water quality monitoring results are awaiting post project analysis.

Lessons learnt

Edit project overview to modify the lessons learnt.

The main flagship site at Madebrook involved the design, planning and construction of a new de-culverted watercourse in an urban setting. The technical challenges were many and steadily overcome by the project team. Costs were high and this made budgeting a challenge, good collaboration and flexible design allowed the project to proceed to a successful conclusion. Involving the local community at an early stage and keeping them involved is key in a project which will at times disrupt the local area. Good liaison has helped maintain good will and has helped build confidence as we move on to new projects in the local area.
