Reuse of wastewater in urban conditions for technical purposes

Abstract

The possibility of reusing wastewater from the point of view of solving environmental problems is attracting much attention today. In addition, water-saving technologies are considered as a means of overcoming water shortages. A double system is when, in parallel with a regular drinking water supply, a parallel second network of pipelines is installed specifically for appropriately purified water. These systems are currently the most popular. It is suggested to reuse the toilet water from the bathroom and the bathroom sink. In this case, we will save 80 liters of clean drinking water every day. And this is approximately 0.286 of the total water consumption per day in one apartment. Excess purified recycled water can be used for washing vehicles, streets, sidewalks, pedestrian crossings, as well as for water supply of decorative fountains.
