Water plants may not be kept secret, but sometimes the location of water plants may not be easy to find. This is because in cities, aquatic plants are usually located in hidden places to reduce the impact on the surrounding environment. In addition, the treatment process of water plants also needs to maintain certain hygiene and safety standards, so it may be necessary to limit the degree of opening to the public.
If you want to know the location of the water plant, you can try to find relevant information on the official website of the local government or water company. You can also contact local environmental protection organizations or water resources management agencies to inquire about the specific location and treatment process of water plants.
