A New Method of Obtaining Water from Water Storage Tanks in a Crisis Situation Using Renewable Energy

Abstract

Background: During a crisis situation, water supply systems stop functioning properly. It is necessary to obtain water from sources other than basic ones (reserve water intakes, water storage tanks, bottled water). Methods: We aim to determine the water demand in a crisis situation based on current European guidelines and determine the time to cover the demand for water from water storage tanks during a crisis situation. Results: An installation for drawing water from a water storage tank, which includes water disinfection using a UV lamp, is necessary. Continuity of operation is guaranteed by the use of a photovoltaic installation independent of the power grid. The amount of water stored in water storage tanks is enough to meet the basic needs of the population for up to several weeks. Conclusions: The use of a UV lamp with an independent backup power supply allows maintaining the microbiological purity of water during a long-term crisis situation.
