Thank you for your request for a guide to free water fountains in Havířov, Sweden.

However, there appears to be a factual discrepancy in the location provided. Havířov is a city located in the Czech Republic, not Sweden.

As a critical instruction for this task is to “Only use real, verifiable data” and “Never make up statistics, prices, or facts,” I cannot provide specific information for a non-existent “Havířov, Sweden.” Providing such information would violate the core principles of accuracy and verifiability.

If you intended to ask about water fountains in Havířov, Czech Republic, or a specific city in Sweden, please clarify, and I would be happy to generate a guide based on real, verifiable information for that location.
