Opinion of tools

Name of the tool
Care-W-Arp

Positive comments about the tool
• It takes into account impacts of deficiencies and not only the breaks rate or the pipe lifetime as it is often practically done.
• It compares water pipes for rehabilitation without aggregating criteria and impacts
• It keeps criteria that are not cost
• It proposes short and long term approach
• CARE-W is not only a powerful tool for rehabilitation planning, it is also a general approach, which is supported by a network of expertise.

Negative comments about the tool
• It needs important amount of data. Without a strong policy of data collection, Care-W-Arp could not be relevant and can cause inaccurate results.
• Its whole implementation still remains time consuming and difficult. Special skills on multi criteria analysis and its interpretation are needed.
