7.2 What Are the Typical Schemes and Techniques?

The decentralised storm water management schemes use a combination of pro-
cesses, mechanism and components to deliver their expected benefits. The pro-
cesses involved in these schemes can be broadly classi

ed as source control, swales

and conveyance channels, filtration, retention and detention, wetlands,

inlets/outlets and control structures. 1 The MUS concept incorporates these dis-
tributed storm water management techniques with a shift to the green infrastructure
approach (US EPA 2008 ), to be implemented in different scales: site-speci

filtration, in

c,
neighbourhood and regional. Wide-scale design and implementation of combined
Green Storm water Infrastructure tools such as rain gardens, in

ltration systems,
constructed wetlands, vegetated swales, etc. can provide numerous bene ts and

support a sustainable Blue and Green urban environment ( Table 4 ).
