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.
