The management and reuse of domestic waste water, which refers to wastewater generated from non-toilet domestic activities, are becoming increasingly important in the context of water resource management. A well-organized waste water management system offers a valuable tool for addressing water scarcity concerns while simultaneously reducing pollution entering the hydrological cycle. The primary objective of such systems is to treat domestic waste water and utilize it in applications that do not necessitate drinking water quality. Examples of non-potable reuse applications include industrial processes, irrigation, toilet flushing, and laundry washing, depending on the treatment technologies employed. This thesis focuses on the development of a laboratory-scale domestic waste water treatment system and examines the water flow within the system. The overall aim is to construct the system and evaluate its efficiency in removing impurities from domestic waste water using herbal filters. The thesis encompasses a comprehensive description of the setup process and the subsequent testing of the domestic waste water treatment system. The present study investigates the effectiveness of herbal filters in eliminating impurities from greywater. The results demonstrate that the herbal filter proves to be highly efficient in removing impurities, thereby improving the quality of treated waste water. By implementing such a treatment system, the potential for reusing waste water in various non-potable applications is significantly enhanced. In conclusion, this thesis provides a thorough account of the construction and evaluation of a laboratory-scale domestic waste water treatment system. The focus on utilizing herbal filters highlights their efficacy in removing impurities from domestic waste water. The findings contribute to the broader understanding of waste water management, offering valuable insights for the development of larger-scale domestic waste water treatment systems aimed at addressing water scarcity and minimizing pollution in the hydrological cycle. Domestic waste water management and reuse have gained significant importance in water resource management due to their potential to address water scarcity and reduce pollution in the hydrological cycle. Domestic waste water, which consists of wastewater from non-toilet domestic activities, can be effectively treated and utilized in various non-potable applications such as industrial processes, irrigation, toilet flushing, and laundry washing. This thesis focuses on the development of a open field waste water treatment system and investigates the efficiency of herbal filters in removing impurities from domestic waste water. The objective is to construct the system and test the water flow within it. The study aims to provide insights into the impurity removal and effectiveness of herbal filters in enhancing the quality of treated domestic waste water. Water is an essential resource for life, and its distribution varies across locations. To meet our daily needs and various purposes like washing, cooking, and cultivation, we rely on different water sources and collection methods such as rainwater harvesting, groundwater and surface water collection, and springs. However, the water we utilize eventually becomes wastewater, which can contain pollutants due to its ability to dissolve various substances. Therefore, it is crucial to clean wastewater before its discharge to ensure a sustainable supply of clean water for the future use. Waste water management plays a crucial role in addressing water scarcity, ensuring water quality, and mitigating environmental degradation. By properly treating and reusing domestic waste water, pollution of freshwater resources can be minimized. Domestic waste water, excluding toilet wastewater, contains fewer contaminants, making it suitable for recycling. The thesis aims to describe the process of building a open field domestic waste water treatment system to contribute to the understanding and implementation of effective domestic waste water management practices. Water scarcity, poor water quality, and water-related disasters pose significant challenges for current and future water resources. Domestic waste water management offers a promising solution by reducing pollution in freshwater resources through the reuse of treated domestic water. This approach not only minimizes environmental impacts but also improves the overall water quality. Domestic waste water, originating from various sources such as baths, showers, hand basins, washing machines, dishwashers, laundries, and kitchen sinks, contains microorganisms, oil spills and chemical contaminants that need to be effectively addressed through appropriate treatment methods. The principles of domestic waste water management revolve around the efficient use of water by minimizing waste and exploring alternative water sources. Reusing treated domestic waste water for non-potable applications ensures sustainable water use, reduces freshwater consumption, decreases wastewater production, and ultimately leads to cost savings on water bills. Even in areas with abundant water resources, water recycling through domestic waste water management remains crucial for achieving sustainable living practices. In the literature review, Lucy Allen, a research associate at the Pacific Institute's Water Program, is mentioned. Her research interests encompass water quality, drinking water regulation, and the interconnectedness of water, energy, and climate change. With her background in conservation and resource studies, she has contributed to research projects on soil organic carbon cycling and the impact of earthworm invasion on soil organic carbon turnover and stability.
