What is the management scope of the property company for the water supply system?

Property management companies have regulations on the management of water supply systems in various places. Usually, the management of high-rise buildings is bounded by the total billing water meter of the water supply pump house in the building, and the multi-storey buildings are bounded by the tap water meter wells outside the building. Water supply is responsible for the water supply pipelines and equipment outside the battery limit, and the property management company is responsible for the maintenance and management of water supply pipelines and equipment from the battery limit (including water meter wells) to users.
