There are many types of cisterns. As most are not self-cleaning, it is a good idea to clean your cistern:
• at least once a year sludge and sediment build-up needs to be cleaned out, more if water looks, smells or tastes different.
• if any contaminants are detected inside the system (e.g., surface water from overland flooding, rodents).
• after installation and sediment needs to be removed from the bottom of the tank.
