"Temporary water" refers to the temporary provision of drinking water in situations where regular supplies are not available. This can be the case, for example, during construction projects, events or in crisis situations such as natural disasters. Clean drinking water is provided by mobile systems, tankers or temporary pipes. The quality of the water must meet the strict requirements of the Drinking Water Ordinance to ensure people's health. This solution is particularly important to ensure security of supply in emergencies or in infrastructure projects.
