BackgroundBackground WSPs provide a systematic approach for assessing risks to water
quality and identifying appropriate management plans.
However, operators of small community water supplies do not always have the expertise or resources to undertake risk assessments
A generic RA tool would help address this problem.
The tool should be targeted towards an audience with some knowledge of water systems (operators/regulators) e.g. public health/environmental health officers, local/regional authorities etc
Training and field guide materials in Phase 2 (increase reach)
Australian toolAustralian tool Health Canada reviewed existing tools and found that the Australian
Community Water Planner provided a useful platform. The Aust tool incorporates many features of WSPs (not surprising)
However, the Australian tool needs redevelopment. This includes:o broadening the scope (more required on chemical quality)o improving international applicability (e.g. range of sources and supplies,
terminology)o Including more information on operator qualificationso coverage of household elementso risk prioritization
The Australian tool includes some modularisation to reduce complexity for the user but this needs enhancement
The Aust tool is CD based and written in an old language
Gap analysisGap analysis Health Canada circulated written materials from the Australian tools
seeking input into the gap analysis from SCWSM network members
Contractors have been engaged to use this feedback and further review of existing material to broaden applicability considering conditions in regions such as:o Western Pacific o Sub-Saharan Africao South East Asia o Arctico Sth America
Issues being assessed include:o catchments and source water (types and protection)o treatment technologieso distribution, collection and storage
Outputs available January 2011
Australian developmentsAustralian developments Original CWP focussed on microbial quality. A 2nd web-based tool has
been developed to deal with chemical, physical and radiological quality
The new tool is written in a more up-to-date language which has wider use. It includes some features considered desirable for the International tool including:o risk prioritization and o enhanced modularization
Prior to release of the 2nd tool a 3rd tool started development. The aim is to combine the CD based microbiological tool with the web-based chem, phys radiological tool. The same contractor and software company has been retained
There are selfish Aust drivers for the 3rd tool but it should be useful for the project (newer language, wider range of parameters, lessons learned). Will be completed in 2010
