Over the past 20 years, the use of Best Management Practices (BMPs)
in the United States has been instrumental in reducing both the
detrimental impacts to receiving water quality and the exacerbated
flooding caused by urbanization and storm water drainage. More
recently, Sustainable Urban Drainage Systems (SUDS) have started to
be used in the United Kingdom. Both SUDS and BMPs attempt to mimic
the drainage patterns of the natural watershed, and can also
provide a degree of treatment needed to improve the quality of the
water discharged to an acceptable level. The costs of conventional
stormwater collection systems are determined primarily in terms of
initial capital expenditure. Long-term maintenance costs are
absorbed by stormwater authorities that are responsible for
maintaining their infrastructure as part of their 'asset base'.
Currently, only a few of these responsibilities exist for BMPs and
SUDS, which generally incorporate surface components and are often
dependent on landscaping rather than on traditional construction
techniques, but may require significant regular maintenance. Any
potential adopting organization will require guidance on the
maintenance regimes of different types of systems and how such
regimes translate into long-term adoption costs. The project is
being conducted in two phases. Phase 1, which is the subject of
this report, includes a literature review and a survey of
stormwater authorities and organizations in the U.S. and U.K. to
identify the most commonly used BMPs and SUDS and to determine the
availability of data on their cost and performance. Phase 1 also
involves establishment of protocols for whole-life costs and
performance data for BMPs and SUDS. Protocols for whole-life costs
will be published separately. An additional outcome of Phase 1 will
be the selection of a limited number of BMPs and SUDS authorities
or sites for qualitative or quantitative monitoring and further
assessment during Phase 2.As part of Phase 2, the operation of
selected BMPs and SUDS will be monitored over a one-year period in
terms of pollutant removal and hydrologic/hydraulic efficiency, and
applicability of their design criteria and maintenance regime. The
protocols developed in Phase 1 will be used to assess BMPs/SUDS
performance and whole-life costs.
