Proposed Action Plan for Water Security at the Paineiras Surface Water Intake as a Contributing Factor to Urban Resilience in the Municipality of Jaú (SP)

Abstract

Objective – The general objective is to propose an action plan for water security at the Paineiras surface water intake as a contributing factor to urban resilience in the municipality of Jaú (SP).
Methodology – The method consisted of a literature review, a field visit to the Jaú River, application of a risk prioritization matrix, and use of the 5W2H matrix.
Originality/relevance – The study addresses the gap of lack of integrated municipal planning for water management in urban rivers, exacerbated by uncontrolled urbanization, soil sealing, and climate change, as exemplified by the Jaú River in Jaú-SP. The academic relevance lies in the intersection between urbanization, water security, and urban resilience, aligned with SDG 6 and studies on vulnerabilities in basins such as Tietê-Jacaré.
Results – The results showed that 39% of environmental risks reached severe or very severe levels, with constructed risk highlighted as the most aggressive due to changes in the watercourse, excessive soil sealing, and construction of urban drainage works not integrated with the natural landscape. Among structural actions, the implementation of adaptive works for land use (erosion, irregular solid waste disposal, and flood control). Among non-structural actions, there are continuous environmental mobilization programs to increase awareness and motivation of the population on a collaborative and voluntary basis to combat water contamination. In conclusion, urban resilience, based on water security, depends on the engagement of public managers with long-term planning and monitoring of adverse effects on the environment and society.
Theoretical/methodological contributions – The main contributions include the application of the semi-quantitative risk prioritization matrix (NBR 17080) and the 5W2H matrix to structure action plans against 39 severe risks. These methodological findings offer objective tools for risk analysis in surface water intakes, complementing literature review and field data to prioritize constructed, natural, social, and productive risks.
Social and environmental contributions – The main contribution was the structuring of actions for monitoring hazardous events that can negatively impact the water quality of the Jaú River and, thus, compromise the water supply and its various uses in the municipality, especially in the face of climate change.
