Gray Water Treatment System for Home Garden and Irrigation

This paper outlines an in-depth analysis of the design, construction, and evaluation of the greywater treatment system for home garden and irrigation utilization. Greywater is the wastewater generated from household activities (excluding toilet waste) for instance; kitchen sink, hand basin, showers, and laundry, which can be effectively treated and reused for home garden irrigation purposes. The primary objective of this research is to design and construct a greywater treatment system that can effectively collect, treat, store, and supply greywater for home gardens and irrigation systems while adhering to relevant local standards and OHS regulations. The finalized design incorporates a combination of the gravity flow system, pumped system, sedimentation and filtration system. To evaluate its performance and effectiveness, laboratory tests of water samples prior to treatment process and post treatment process was collected and conducted, analyzing parameters such as Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), Dissolved Oxygen (DO), and pH level. The development of a greywater treatment system for home garden and irrigation is a fundamental phase in promoting sustainability, lowering dependency on freshwater sources, and minimizing the environmental impact of household activities. This work specifically supports several SDG 6’s targets and indicators like local water resilience, safe treatment and sustainable water reuse. The development of greywater treatment system for home garden and irrigation addresses a holistic intervention that directly improve SDG 6.
