Greywater Recycle and Reuse for Domestic and Irrigation Purposes

Abstract

Water scarcity has been regarded as an emerging issue since years around the world. According to the reports, it is found that India may end up with 50% water deficiency by the year 2030. This issue has motivated the treatment of grey water, which can be an alternative source for different purposes such as irrigation and toilet flushing. The paper presents the typical characteristics, the finest design of laboratory scale grey water treatment which comprises of natural and physical operation such as primary settling of heavy particles with the help of vermicompost, charcoal, coarse aggregates and fine aggregates (sand) and existing regulations for grey water treatment and reuse. The overall performance of the treatment plant produced a very improved quality of grey water, whose values found to be in the limits recommended for domestic and irrigation purposes. The treatment plant was found to be cost-effective and easily operated manually. The treated water can be used for gardening, flushing toilets, car washing, fire fighting, industrial purposes, etc.
