Sustainable Water Management: Greywater Reuse and Smart Irrigation at Pusgiwa UI
Main Article Content
The increasing demand for water in urban areas, coupled with challenges related to water scarcity and environmental concerns, underscores the need for effective fresh water management practices. This study explores the potential for greywater reuse and smart systems to meet domestic water needs at Pusgiwa UI. The methodology involves quantifying water consumption across different areas of the building to identify potential sources of reusable greywater for non-potable applications such as flushing toilets and landscape irrigation. Through water balance analysis, it was found that greywater from ablution (wudu) activities can be directly repurposed for irrigation, while greywater containing soap and grease requires treatment before being reused for flushing. The findings indicate that implementing greywater reuse can save approximately 45.5% of fresh water consumption. This study provides practical solutions for sustainable water management, demonstrating significant reductions in fresh water usage and offering a replicable model for other urban buildings aiming to optimize water resources efficiently.
