Securing
financial resources and providing incentives (including subsidies) are also
important factors for the uptake and expansion of these techniques. Design must
consider the vertical integration of measures and their horizontal application in all
possible scales: single dwellings, residential multi-units, public and commercial
buildings, streetscapes, blocks, etc.
Some example applications of combined blue-green interventions are provided
below, followed by a summary overview of the bene
ts (Table 5 ) and indicative
costs (Table 6 ) of the blue-green techniques described before.
Example 1
Possible overall strategy for a typical suburban home. A rainwater tank
supplies rainwater for toilet
flushing, washing machine, and for outdoor use
whilst water ef
fittings reduce main water consumption elsewhere.
During prolonged or heavy rain, water over
cient
ows from the rainwater tank to a
retention trench. Storm water run-off from paths, driveways and lawns is
directed to garden areas. Excess run-off from impervious surfaces is directed
to the retention trench, or over
ows to the street drainage system.
