Individual decentralized non-potable water system: the need for quality and quantity management

The method used was the case study. Hence, we characterised the system and collected information from users. The results show that the non-drinking water system, in addition to not having an impact on the reduction of water consumption, led to an outbreak of gastrointestinal infection among the population of the building.

This fact occurred due to the lack of training of the professionals involved in all stages of the system, particularly in the operation and maintenance phase, which affected the health of users. It is concluded that professional training to run, operate and maintain non-potable systems is essential to ensure the systems' efficiency and to preserve the health of users.
