River Granta at Stapleford, Sept 2019
Cam valley Forum publishes Let it Flow! – detailed proposals to restore the River Cam
Our new report – Let it Flow! – explains the environmental impact of water abstraction on the Cam Valley and calls for actions in seven main areas to protect and restore the river:
- Substantial reductions in groundwater abstraction from the aquifer that feeds our Chalk streams. Where the water environment is being damaged, licences need to be amended or terminated to deliver real cuts in actual abstraction, not just paper savings in licensed amounts
- Investment in new sources of public supplies. Proposed strategic north-south transfers of water should be extended to benefit the Cam Valley too. Locally, high river flows should be captured in a new reservoir in the lower Cam Valley, once they have flowed through it in as natural a way as possible, and be redistributed as necessary.
- Investment in water reuse and aquifer recharge schemes. Sewage treatment works need to be upgraded to deliver better treated water to be reused for public supplies and to recharge the aquifer and/or to support irrigation.
- Investment in the harvesting of rainwater and recycling of greywater. Our local planning authorities need to ensure that schemes to harvest and recycle water become commonplace and help to make Cambridge a ‘Water Sensitive City’.
- A step-change in attitudes to water use through metering, leakage control and demand management. Cambridge should become the ‘No. 1’ water-saving city and the Anglian Region the ‘No. 1’ water saving region in England.
- Significant reductions in water pollution and investment in work to enhance habitats and natural processes. Action is also needed to: reduce pollution from land, businesses and homes; and to rectify the impacts of past river modifications, which have reduced connectivity between reaches (e.g. weirs) and between rivers and their floodplains.
- Improved resilience, not only for public water supplies but also for the environment. An increasing population, economic growth, intensive land management, and climate change, will all bring new pressures to bear on the Cam Valley’s limited and precious water resources. We all have a moral obligation to protect our river environments for future generations to enjoy.
Our 12 further recommendations are being submitted to Water Resources East, the body currently charged with planning the future for water resources in our Region. We want to work with the other members of Water Resources East to create an ‘Integrated Water Resource Management Plan’ to secure the best possible outcomes from this process.
We commend Let it Flow! to everyone with an interest in the environment of the Cam Valley. We would welcome comments and support and look forward to developing our ideas further in close consultation with all relevant interests in the months to come.
