Indirect tangible

with well designed
and constructed
WSUD elements are
the environmental
outcomes such
as reductions
in potable
water demands,
downstream
pollution and
waterway
rehabilitation
works.
An important part of implementing
WSUD strategies is the cost the systems
pose to Councils. There are many
approaches to computing and accounting
the cost of infrastructure. In the case of
land development, the capital cost is
often borne by the developer with the
asset subsequently assumed by local
government with associated maintenance
and renewal responsibilities.
The life cycle cost of an asset is made up of
its capital cost, operational and
maintenance cost, renewal cost and
decommissioning cost. Often not
included in a life cycle cost/benefit
analysis are the benefits both directly
accrued to the development, and
indirectly attributed to the works within
the development. The benefits directly
accrued to the development are reflected
in the increased demand for properties in
the development as reflected in the sale
price. Indirect tangible benefits associated
with well designed and constructed
WSUD elements are the environmental
outcomes such as reductions in potable
water demands, downstream pollution
and waterway rehabilitation works.
Organisations are now considering the
total community costs in evaluating water
management strategies.
