SMALL SCALE WASTE WATER TREATMENT SYSTEM IN SINGLE HOUSES IN SRI LANKA

Water, an indispensable resource for both flora and fauna, is crucial for sustaining life. Wastewater, comprising utilized water contaminated with various substances like human waste, food residues, oils, soaps, and chemicals, originates from diverse household sources such as sinks, showers, toilets, and appliances like washing machines and dishwashers. Treating wastewater is vital for environmental preservation and public health. The primary objective of wastewater treatment is the elimination of suspended solids before discharging the remaining water, termed effluent, into the environment. The focus of this project is wastewater treatment in individual residences, a concern addressed through various methods globally. However, our initiative aims to introduce the Bio Digestor system for household wastewater treatment across Sri Lanka. Household water consumption is often excessive, resulting in wastage without proper treatment. Surplus treated wastewater necessitates environmentally conscious disposal methods. While connecting to municipal sewers is common, it poses environmental risks, including overflow during heavy rains and potential blockages. Moreover, different types of wastewater—greywater, blackwater, and stormwater runoff—contain distinct contaminants, requiring specific treatment approaches and disposal considerations. Our Bio Digestor system offers a versatile solution capable of treating various types of wastewater efficiently. Unlike some systems requiring extensive infrastructure modifications, ours seamlessly integrates into existing setups with minimal adjustments, making it accessible for households worldwide, regardless of location or environmental conditions. Extensive research, including surveys, field studies, and experiments, has bolstered our confidence in the feasibility and effectiveness of the Bio Digestor system. We anticipate its successful implementation and foresee its multifaceted benefits for individuals and communities, a topic we will delve into further in subsequent discussions.
