Sustainable Stormwater Management Techniques
A range of sustainable drainage techniques are available to developers, which can be applied individually or in combination. A 'treatment train' combining multiple techniques (such as water butts, permeable paving, swales, and ponds) delivers the best results.
There is a wide range of sustainable drainage techniques available to developers,17 which can be applied, individually or in combination. A combination of techniques will deliver the best results – for example, a housing development where downpipes are fitted with water butts, the driveways use permeable paving, all connecting to conveyance swales, which in turn are linked to a pond or wetland area. This combination of drainage techniques is known as a 'treatment train'.
