Abstract:
Stormwater quantity and quality
can vary widely depending on the landscape of
the area and amount and intensity of
precipitation. Stormwater is a good source of
water which can reduce the demand on potable
water supply. Treated stormwater can also be
employed for non-potable uses which account
more than 40% of household domestic water
demand. Wetlands, bio-retention, and
permeable pavements are widely used in
stormwater management. Current bio retention systems used in Australia for
stormwater pollution control seldom provide
the water quality necessary for water recycling
due to their varies removal efficiency for a range
of inflow conditions and pollutants. Stormwater
discharge in certain periods is relatively large,
and therefore, it needs to be treated intensively
at high rates. There is a large gap of research
data available on improving bio-retention
media for effective stormwater treatment.
