Construction site problems due to lack of experience and awareness on new
technologies of the people involved in the construction process.
2.3 Was the Project Successful? In What Way?
Overall, Lynbrook Estate is considered a successful demonstration project for the
application of an innovative stormwater treatment system in Melbourne and one of
Australia
s WSUD leading examples (Farrelly and Davis 2009 ). The success of the
project, mainly regarding collaboration across all involving partners as well as the
positive commercial and technical performance results, affected signi
'
cantly the
improvement of sectoral con
dence in Urban Stormwater Quality Management
(Brown and Clarke 2007 ).
2.3.1 Facts
￿
Monitoring results indicated that the unconventional stormwater treatment
systems applied in Lynbrook Estate present better hydraulic performance when
compared to traditional drainage systems (Brown and Clarke 2007 ) and more-
over, regarding water quality issues, provide a 60 % reduction of total nitrogen,
80 % reduction in total phosphorous and 90 % reduction of total suspended
solids.
Despite the earlier concerns of the developers on the consumers
'
reactions to the
￿
new technologies applied, sales were signi
cantly increased shortly after the
construction began, while sale prices of the subdivisions incorporating WSUD
features reported to be increased by a rate of 20
-
30 %.
A cost comparison study indicated that implementing WSUD stormwater
drainage systems could be only 5 % more expensive while comparing to con-
ventional systems (Lloyd 2001 ; Wong 2001 ).

The local community considered the developments to be more

attractive
'
(Lloyd 2004 ) than the traditional ones.
In 2000, Lynbrook won the President
s Award in the Urban Development
Institute of Australia Awards for Excellence and in 2001 the Cooperative
Research Centres

Association Technology Transfer Award.
2.4 What Can We Learn from the Case of Lynbrook Estate?
