The Crane Valley Partnership

Clean Clear Water

We want to ensure all misconnections are identified and addressed at all priority outfalls by 2021

Misconnected sewers are one of the main sources of pollution on the River Crane. We want to identify their outfalls and ensure all properties in the catchment are correctly connected to the area’s sewer system to prevent this problem from continuing. Thames Water are working collaboratively with the Environment Agency to identify misconnections through data collection and analysis of pollution sources and specific contaminants.

Once we have found the misconnections responsible for polluting the Crane, we want to work with property owners to ensure they are taking the right steps to ensure that their dirty water goes to the nearest waste water treatment works before it enters our river. We want to inspire the local community to take action against domestic pollution through promoting a greater understanding of its sources and impacts.


We want to ensure that pollution is understood and new cases are identified and controlled effectively

Having a greater understanding of pollution on the river is very important. We need to be aware of the points where pollution has entered the river in the past so local people know where problems may occur, what to look out for and who to report it to. We want to ensure that all pollution incidents are reported to the Environment Agency immediately so they can record the problem and respond appropriately.

To aid in this, a project to assess the phosphorus levels  within the river is currently underway.


We want physical, chemical and biological water quality within its desirable limits, to achieve Good Ecological Potential

Implementing the Water Framework Directive is critical and we want to achieve its targets for good ecological potential . We aim to do this through a range of actions including investigating the feasibility and effectiveness of creating wetland habitats at polluted outfalls throughout the catchment to intercept pollution.

We also want to encourage in-channel vegetation to capture suspended particles and improve levels of dissolved oxygen. We plan to monitor the water quality of the river with Environment Agency water quality analysis and through other partners monitoring natural water quality indicators such as aquatic invertebrates.


We want to improve the quality of surface water runoff using Sustainable Urban Drainage Systems in appropriate locations

We recognise contaminated surface water runoff as one of the main pollutants of the river. We want to assess appropriate locations for Sustainable Urban Drainage  Schemes and implement them where possible.

Local people can do their bit too. How many hard surfaces do you have in your garden? And have you ever thought about replacing them with a permeable material or grass? We all can do our bit to reduce the amount of surface water running into rivers from our concreted, urban landscape. The time to act is now!
