River Ter

The River Ter is 31km long and is a catchment in its own right. It has multiple directives that work to protect it, including the Freshwater Fish Directive (Headwaters to Great Leighs STW, Great Leighs to Chelmer), the Nitrates Directive and the Urban Waste Water Treatment Directive.

The Water Framework Directive (WFD) status for this waterbody is at moderate status with the failing being for phosphates. The rest of this waterbody classed as good and high for other factors; although currently there is no data for diatoms or macrophytes.

The phosphate levels within this catchment are classed as moderate and therefore require some work in order to allow the whole catchment to be classed as good. Sources of phosphates have been identified as point sources from sewage treatment works and other licensed dischargers, diffuse sources have also been identified as agricultural run-off. In order to address this problem the compliance of sewage treatment works with discharge consents needs to be checked so that major sources can be identified. Once the major sewage treatment works inputs are identified, the Environment Agency can work with water companies to introduce phosphate stripping mechanisms. Other local sources need to be identified and local landowners need to be worked with to ensure phosphate levels are reduced as much as possible from land run-off.
