Anyone wondering whether to decide for or against a cistern must first and foremost determine their own motivation. The main aim of the cistern is to save money, provide a more ecological water balance and / or generate other advantages?
The pure water savings by replacing drinking water with cistern water must be taken into account in conjunction with the wastewater charges. When calculating the wastewater charges, the laws have been changing for a number of years and require the municipalities to use a new calculation technique. This results in changed economic framework conditions that can strongly influence a fiscally justified decision.
The ecological aspect that plants are watered with clean and expensive clarified drinking water is definitely an argument in favor of a cistern. The alternative of a well or the combination of both should also be checked. A yes or no for a cistern is ultimately view.
