What is grey water and how we can use it? There are lots of proven and operating grey water systems in the world. India is in this regard quiet lagging country, where system doesn’t have this position, neither instance of application. Due to approach the topic of reuse systems, this article describes grey water system reuse and its brief characteristic. The main aim of this article is to characterize the grey water system, its design and water treatment on the case study by pointing out its saving potential. Therefore this study confirms, that system of alternative recycled water use, can save particular source of potable water, where the water is unnecessarily wasted and used where drinking water quality is no needed. In parallel to water savings, grey water system can bring financial savings, which are relevant especially for users at decision-making processes. It is obviously that system have advantages and disadvantages, but if we are sustainable thinking, we have to refer about every drop of water we can save, and we can consider that grey water system is the way we can reach it.
