Secondary pressurized charging standard

Most of the newly-built commercial housing projects are high-rise, but buying high-rise buildings has many disadvantages. First, the pool is large, the housing maintenance fund is high, and the affiliated houses are generally planned underground. Secondly, buying a high-rise house must pay the elevator fee, even the secondary pressurization fee for water supply. What's the charging standard for the secondary pressurization fee? Let's take a look with experts.

What is the charging standard for primary and secondary pressurization fees?

The charging standard for secondary pressurization of water supply is generally calculated from the sixth floor, and each party charges 0.3-0.5 yuan. However, this fee should be determined according to the regulations of the price department of the local government, and can only be collected after being approved by the residents. Property management companies also need to publicize the charging items and charging standards in a prominent position in the management area.

Second, under what circumstances it is necessary to carry out secondary pressurized water supply.

Generally speaking, when the height of public buildings exceeds 12 meters and the height of residential buildings exceeds 6 floors, secondary water supply facilities must be designed and constructed. However, if the commercial-residential mixed building has two floors or more, secondary water supply shall be implemented according to public buildings. The water quality of secondary pressurized water supply is no different from normal water, but it can transport normal water to a higher position, breaking the traditional high water supply.

Secondary pressurized water supply is to increase the water pressure by air pressure and other methods, so as to transport the water to a higher water level. It has the forms of steady flow compensator control, automatic current limiting mode and pressure control point mode. When the water supply is insufficient or the water consumption exceeds the supply capacity, the water supply vacuum suppressor is turned on, allowing air to enter the steady flow compensator to suppress negative pressure. With liquid level control, once the water level is lower than the low level, the pump will stop working.
