SuDS in London - a guide

Some SuDS components are linked to
buildings and structures that help define
the public realm. These may include:
• Living roofs’ (green, brown or blue
roofs) to provide source control
Retrofit cycleway and SuDS in Lyon
• Water butts and tanks to intercept
and harvest rainfall by disconnecting
and diverting downpipes
• Rain gardens to create temporary
localised ponding for roof runoff,
allowing plants and trees to
benefit from that ponding
• Rainwater planters to attenuate
in above ground planters, with
integral storage and slow release
Other SuDS components can be
delivered by better management of
existing assets, including:
• De-paving, bioretention and street tree
planting, retrofitted as part of already
planned annual highways maintenance,
repair and improvement programmes
• Re-purposing linear green infrastructure,
such as verges and embankments
along roads, railways and waterways
• Decompacting existing parkland soils
• Repurposing existing green space
for swales, rain gardens and
bioretention components
• Protecting existing assets that are
already providing a SuDS function,
including street trees, parks and gardens,
verges and infrastructure corridors
The SuDS components are described in
more detail in the order found in
CIRIA C753 The SuDS Manual.
