Abstract

ABSTRACT:

The objective of this work is to compare the water quality standard required by the Brazilian standard of rainwater harvesting from roofs for non-potable uses, NBR 15527 (ABNT,2019), with national and international guidelines. Legislation, manuals and Brazilian regulation regarding rainwater, gray water, recreational waters and potability were analyzed, as well as German, US and Australian guidelines on rainwater harvesting systems. Initially, the water quality standards required by the national documents were identified. Then, similarities and divergences were observed between the requirements according to the final water use. Subsequently, the same was done with the international documents. Comparing the data using the Brazilian standard on rainwater, it was verified that there is inconsistency in its requirements. The results suggest that the current version of NBR 15527(ABNT, 2019) is too restrictive, even though it has been recently modified. Therefore, a model was developed as a suggestion for the adequacy of the regulation, with different quality standards and usage purposes, aiming at better coherence with the current global scenario.
