Urban Drainage and Stormwater Management - The Basics
To meet the needs of the environment and community it is essential that urban drainage systems are designed as a total solution. The key is integrating the practices of flood management, water sensitive urban design, stormwater quality control, community needs and preservation of the natural environment.
The design of major urban drainage systems requires specialist expertise in hydrology, hydraulics (1D and 2D), water quality, sedimentation, planning and landscape architecture and ecology.
BMT WBM offers an integrated approach, developed by specialists in those fields, which is crucial if total solutions to urban drainage are to be designed.
The Breakdown
Stormwater Control
With the development of urban areas, stormwater quantities increase significantly from natural levels. These effects need to be assessed in a quantitative manner to enable the design of waterway corridors which convey stormwater in a safe and environmentally sensitive manner. Stormwater Best Management Practices are selected to achieve defined stormwater control objectives.
Community Safety and Awareness
Assessment of socio-economic impacts from urban flooding. Community consultation and awareness.
Impacts of Urbanisation
New developments affect catchment rainfall-runoff. The likely impacts need to be known before decisions are made.
Integrated Engineering, Planning and Ecological Considerations
Development of drainage systems including pipe networks, overland flowpaths, structures and retention basins, ensuring that all waterway layouts and designs are ecologically sensitive. The development of drainage plans which adopt multi-use roles in waterway corridors including the consideration of floodwater conveyance, water quality/pollutant export control, environmental protection, public open space provision and regional transport linkages.
