Our plan for Teesside

Environmental risks and concerns

Our environment! A space we all share, rely on, and need to look after. As a result of a reduction in green space, population growth and climate change, we expect to see a higher risk of pollution events and increased flow into our rivers and beaches.

Flood risk

An effective sewerage system must be able to handle sewage and rainwater, to reduce the risk of flooding in our homes and communities.


A big part of delivering our services, is making sure our sewage treatment works can handle demand, without negatively impacting the receiving watercourses.
