Water Quality & Quantity

There is national concern about the condition of rivers and the impacts on them of agricultural pollution, waste water, highways runoff and other pollutant sources. 

The Water Framework Directive (WFD) classifications undertaken by the Environment Agency provide a standardised methodology for assessing the condition of our rivers. South West Water monitors water quality closely in the river as it is a drinking water catchment. Additionally, in recent years a significant community-led campaign, through Friends of the Dart, has developed on the Dart to register designated bathing waters  

Waste water management, Water resource management and Flood risk management are the three closely connected Action areas under this theme.  

Priority Actions Objectives What needs to happen Key Partners
Ww Waste Water Management
Ww1 Upgrade sewage treatment works

Improve water quality

Reduce phosphate levels

SWW has plans and funding to upgrade STWs at Widecombe, Rattery, Kilbury, Totnes and Dittisham by 2030. SWW
Ww2 Upgrade priority CSOs throughout

Improve water quality

Reduce phosphate levels

Several high-spilling CSOs are due for upgrade by 2030 and all CSOs should be upgraded by 2035.     SWW
The Bidwell Brook Partnership has identified a project to install NBS treatment in the brook’s water meadows. Bidwell Brook Partnership
Ww3 Promote “Love your Loo” and “Think Sink” campaigns

Reduce pressures on public wastewater network

Improve water quality

SWW delivers a campaign focused on how people can reduce their impacts on the Dart and the messages of this campaign need to be communicated more widely. A campaign is needed that other organisations can adopt and support, alongside SWW or independently from it.

River Dart Catchment Partnership
Ww4 Encourage better maintenance of private sewage systems

Improve water quality

Reduce phosphate levels

Greater awareness is needed of the impact of private sewage systems. This should be delivered as part of the campaign focused on how people can reduce their impacts on the Dart. To include septic tank maintenance, misconnections.

Wr Water Resource Management
Wr1 Investigate impacts of abstraction and implement actions where defined.

Sustain flows.

Support the recovery of migratory fish populations.

Abstraction impacts need to be reduced. A SWW investigation into Littlehempston abstraction is due 2026; the findings from this will inform actions in PR29.

SWW is also carrying out an investigation into the impacts of abstraction on the ecology of the Swincombe – to be completed by 2027; implementing findings by 2030.

SWW
Wr2 Review private abstractions and identify opportunities for reductions

Sustain flows.

Support the recovery of migratory fish populations.

Data on private abstractions is held by the Environment Agency. There is a need to clarify the scale of the problem, identify what the potential mechanisms are to reduce this pressure, and share the results more widely. This would then inform further action, if appropriate. Environment Agency
Wr3 Promote campaign to reduce domestic and business water consumption

Sustain flows.

Support the recovery of migratory fish populations.

Greater awareness is needed of the impact of domestic and business water consumption. This should be delivered as part of the campaign focused on how people can reduce their impacts on the Dart. Residents, tourists and local businesses to be targeted. River Dart Catchment Partnership
FL Flood risk management
FL1 Remove barriers to fish migration

Improve riparian habitats.

Increase infiltration and catchment storage capacity

Existing NFM projects have been established in the main locations subject to flooding, where NFM can help reduce the impact. 

These projects are variously funded and those requiring additional resources need to be further supported.
