They are the easiest techniques to implement with minimal economic installation cost.
They minimise the aesthetic impacts of the engineering techniques.
They work against the water cycle to reduce the impact of natural processes, while minimising risk.
They work with the water cycle to limit significant changes to natural processes, while minimising risk.
The open channel makes it easier to pick out the pollutants.
The open channel makes it easier to monitor the type and quantity of pollutants leaving the area.
The swales stop the water from reaching the main rivers.
The vegetation within the channel will filter out some pollutants.
Permeable paving (bricks)
Carefully chosen vegetation to ensure there are flowering plants throughout the year to improve aesthetics
Carefully chosen vegetation to maximise the amount of interception
Carefully engineered soils to maximise removal of pollutants as the water percolates through
Carefully engineered soils to maximise the amount of infiltration
A path made from concrete with little green crosses in it
A poorly maintained path, as grass is growing between the cracks in the surface material
A path running between two sets of trees enabling access between areas
A path with a permeable paving surface, enabling higher rates of infiltration at source
