What do you mean by water loss? There is also the difference between property fees and health fees.

Generally speaking, there is a difference between energy consumption and loss. Energy consumption refers to water and electricity consumption for residential property cleaning, greening and irrigation, and water and electricity consumption for public areas. This value is basically fixed and apportioned by area or total usage.

The water fee loss refers to the difference between the water entering the waterworks in the community and the water of each household in the community. Usually, there are possibilities such as damaged water pipes and inaccurate water meters in residential areas. If it is determined to be 20%, energy consumption will generally be collected in advance or mixed.

Property fee refers to the cost required for the normal operation of residential property, usually by contract system, which is used to let the property company pay the salary, office and daily consumption of property personnel. Generally speaking, property fees include health fees.

Water fee is the fee paid by the units and individuals who use the water supplied by the water supply project to the water supply unit according to the regulations. It is the development trend of modern legislation to stipulate the collection of water charges. The water laws of many countries implement the system of charging water fees for all or part of the water.

1985, China promulgated the "Measures for the Administration of Approved Collection of Water Fees for Water Conservancy Projects", which made specific provisions on the collection purpose, principles of approved water fee standards, collection, use and management of water fees. The Water Law also stipulates that water supplied by water supply projects shall be paid to water supply units in accordance with regulations.

The purpose of collecting water charges is to make rational use of water resources, promote water conservation and ensure the necessary operation management, overhaul and renovation costs of water conservancy projects.
