Are there safety measures to take when using cisterns for drinking water?

Yes, there are several important safety measures to consider when using cisterns for drinking water, particularly in places like Mallorca where rainwater harvesting is common. Firstly, it's essential to ensure that the cistern is properly constructed and maintained to prevent contamination. This includes having a secure cover to prevent debris, animals, and insects from entering the cistern. Regular cleaning and inspection of the cistern and its components are vital to remove sediment and prevent algae growth.

Furthermore, water quality testing should be conducted periodically to check for contaminants such as bacteria, viruses, and chemical substances. It's recommended to install a water filtration system or UV treatment to further purify the water before consumption. Additionally, it's crucial to keep cisterns away from potential contaminants, such as septic systems or agricultural runoff, and to use non-toxic materials for any plumbing connected to the cistern. By following these safety measures, residents can ensure that the water collected in cisterns is safe for drinking and use.
