Anglian Water wants to create more innovative wetland sites to help cope with increasing demand for its sewage services.
The series of pools created at Ingoldisthorpe near King's Lynn help to filter waste water that's already passed through a traditional treatment plant and it's created a haven for wildlife.
It's the first wetland of its kind in England and filters about a million litres of water a day which then flows into the River Ingol.
To mark a year since the pools were created they've been doing a survey of the wildlife and plant species that can be found on the site- to show how successful it's been. Children from local schools were invited to take part.
The project has been funded by the water company but the wildlife haven has been created by the Norfolk Rivers Trust, which also manages and maintains the site.
If it gets approval from the water regulator Ofwat, Anglian Water wants to create around 30 more wetland filtration sites like this in the East of England.
