Resumen
When it is not possible to supply water through the water supply network, it is necessary to use other resources of the water supply company, e.g., water tanker. This requires maintaining the efficiency of alternative water sources (in terms of quality and quantity). This work focuses on the possibility of using water accumulated in water pipes in a crisis situation. This work proposes a drain well to supply the population with water in a crisis situation. Thanks to this solution, the function of water supply drainage can be combined with the possibility of obtaining water accumulated in water pipes in crisis conditions. In addition, the standards for water demand in a crisis situation are analyzed. This work extends the view on the problem of water supply to residents in a crisis situation by taking into account a new solution that allows the consumption of water accumulated in water pipes.
