Decentralized Greywater Recycling Systems for Sustainable Residential Design

This study examines the effectiveness of decentralized greywater recycling systems implemented as an element of environmentally friendly residential construction intended to lessen the consumption of drinking water and wastewater output. The aim is to design and assess systems which are compact, robust, easy to operate, and self-contained for households. Our approach involves combining advanced filtration (biological and membrane) and disinfection (UV-C) methods to produce greywater suitable for non-potable water supply. Results show a substantial decrease in water demand (up to 40%) and that the quality of water treatment meets relevant standards for irrigation and toilet flushing. This method provides a **critical** solution for improving water sustainability and environmental stewardship in urban and rural housing systems.
