Proposta de lei municipal como ferramenta para proteção de mananciais de abastecimento público: estudo de caso na bacia do Rio Ernesto, Pitanga-PR

Abstract

The United Nations 2030 Agenda proposes 17 Sustainable Development Goals (SDGs). SDG 6, consisting of 8 targets, aims to ensure the availability and sustainable management of water and sanitation for all by 2030. Given the need to protect the public water supply source in the city of Pitanga-PR, the objective of this research was to prepare a proposal for a draft municipal law for the public water supply area, setting parameters and guidelines to protect the Ernesto river basin area. The procedures adopted for the development of this study were a bibliographic review on the topic, survey and systematization of spatial data to obtain cartographic products, and on-site visits to recognize the area. From the results obtained, it was possible to identify the main impacts and risks in the supply area. The water treatment station is located next to the collection point, which in turn is downstream of the PR-466 highway. In addition to the proximity to the highway, the spring area encompasses irregular occupations lacking sanitation infrastructure, the presence of commercial activities with low polluting potential, conventional agricultural practices and, in some areas, the lack and degradation of permanent preservation areas. In short, it is expected that the results of this study will contribute to the municipality's water security and that the draft law can be used as a water resources management tool in other public supply sources, especially for municipalities that do not have municipal legislation specific for this purpose.
