Who cleans the water tank in the park?

The water tanks in the park are cleaned by the water tank cleaning company. When the water tank needs cleaning, the property service center will hire a professional water tank cleaning company to clean and disinfect the domestic water tanks in the park. The water tank cleaning company will test the water quality in the water tank to ensure the safety of domestic water for enterprises in the park. Every year, the water supply company and the property management office will go to the park for inspection, and the property company also needs the water tank inspection report during the annual inspection. Therefore, the water tanks in the park need to be cleaned by a water tank cleaning company.
