BMP web-based catalogue + tutorial

The Best Management Practice (BMP) catalogue, contained within the DayWater ADSS, is a comprehensive on-line information resource and database which provides detailed information on 15 structural BMPs (including infiltration systems, ponds, basins and permeable surfaces) and 5 non-structural BMPs (including snow management and street cleaning practices).

It has been designed as an urban stormwater decision support tool to assist end-users according to their existing level of expertise in the use of BMPs for stormwater management. Thus, for those practitioners with a limited experience of using stormwater BMPs, it provides a comprehensive overview of the wide variety of system types, designs and modes of operation of structural BMPs, as well as providing background and information on non-structural stormwater BMP approaches.

As an on-line facility, it also acts as an accessible reference point for urban drainage practitioners who require specialist information on the use of BMPs. For example, in the case of BMP designers (such as landscape architects) or those responsible for approving the inclusion of BMPs within new or existing developments (local authorities and regulators), the catalogue provides clear information on both BMP performance and operation and maintenance requirements.

Comparisons of the costings associated with the different BMPs are provided within the catalogue through both a review of available data (accessed through each BMP type) and an interactive format (accessible through the BMP costings tool link). A general description is provided for each BMP, supplemented by a more detailed description in the form of a pdf Characteristics file as well as photographs and example types (overviews providing information on actual examples of a particular BMP system in use within Europe). The catalogue also contains information on the sources and loads of a range of stormwater pollutants, as well as a BMP dimensioning tool. Where it is considered relevant, the BMP catalogue also provides links to a range of external BMP design manuals and websites.

The format of the Characteristics file varies from BMP to BMP and particular differences exist between structural and non-structural systems. The characteristics of non-structural BMPs may have a strong practical basis as is the case with Street cleaning and Snow management practices or may be more theoretically based as is the case for Control of impervious area development, Educational aspects and Reduction in pollutant usage. The Performance section contains current information on the pollutant removal efficiencies of specific BMPs but due to its derivation from a range of different international sources, the data is subject to different levels of reliability. The operation and maintenance needs of a specific BMP indicate that this is currently one of the major concerns about the applicability of BMPs as source control facilities in urban areas.

Therefore, it is important that potential end-users are fully conversant with the O&M requirements associated with a particular BMP. The photographs section includes images from across Europe chosen to represent the typical applications/installations of a particular BMP. The use of pictorial representations indicates to prospective end-users of BMPs the situations in which different BMPs can be and have been used. The stored images are categorised by their country of origin and are supported by descriptive captions.

The Example types section of the BMP catalogue effectively complements the photograph section by enabling information regarding the actual use of a specific BMP in the field to be described. The information is contained in pdf files, which are accessed by clicking on the hyperlink Example types in the appropriate BMP specific page. Where available, examples of both successful and unsuccessful BMP systems/approaches have been included, as information on both positive and negative experiences are obviously equally valuable as an information resource.

The external appearance and functioning of the BMP catalogue has been continuously modified during its development in response to feedback received from both internal and external project partners with the objective of producing an urban stormwater management support tool which is both useful and user-friendly. Recent examples of implemented modifications include the provision of brief outlines of each BMP system or approach to complement the existing detailed descriptions, and the increased access to photographs of BMPs from a range of different European countries. The on-line structure of the BMP database has been designed in such a way that it can continue to be updated and developed as further information becomes available, thus enabling the database to evolve in response to both new BMP developments and the perceived requirements of urban drainage practitioners.
