In other words: Rehabilitate the right sewer at the right time by using the right rehabilitation technique at a minimum total cost, and before serious failures occur (pro-active approach). Up to the upstart of CARE-S some analytical tools to assess the technical or functional state of sewers or the needs for rehabilitation had been developed or were under development in several European Research Centres and Universities. Usually, though they did not take into account all aspects of rehabilitation decisions and had only been applied for a limited number of wastewater services. They needed to be tested, validated and aggregated and they needed to be linked to those performance indicators (PI), that are the key criteria for rehabilitation decisions. The specific objectives of the project were to improve these tools, link them and to make them usable for the formulation of a rehabilitation strategy.
The CARE-S resulted in a product for decision support for sewer network rehabilitation, including:
CARE-S comprises a "Sewer Rehab Manager" prototype and a handbook. The deliverables are available on CD-ROM and (partially) on paper.
