How does the property drainage work?

Residential property management does not allow the balcony to drain washing water, because there will be two wells in the residential area, one is a rainwater well and the other is a sewage well. The balcony floor drain is connected to the rainwater pipe to drain the water into the rainwater well. The water from the rainwater well can be directly reused in the community, that is, used for watering the greening of the community, or reserved for fire fighting. The water for washing clothes cannot be directly reused because it contains the chemical cost of cleaning products such as washing powder or washing liquid, and needs to be discharged into sewage wells for special treatment.

The water for washing clothes, the water produced in the kitchen and the water produced in the bathroom all belong to sewage and need to be discharged into the sewage well of the community. The water in the sewage well will be diverted to the sewage plant again. The sewage plant will purify the sewage and then discharge the treated water into various rivers to prevent the sewage with chemical cost from polluting the environment.

Different communities have different designs for sewer pipes, so how to discharge the water from the washing machine depends on the design of the water pipes in this house. In some communities, rainwater pipes and sewage pipes are directly designed on the balcony. The floor drain is connected to the rainwater pipe. Therefore, the owner will clearly tell the balcony before the renovation that the floor drain can't discharge the water for washing clothes. Therefore, in the decoration, the owner and the decoration master will be very clear that another sewage pipe interface is used to install the washing machine drainage pipe interface. Of course, there are also some communities, and the bathroom design space is relatively large, so the owners will be required to put the washing machine in the bathroom in a unified way, and there is no sewage pipe interface on the balcony.

When we know that there are rain wells and sewage wells, we can naturally understand why the property does not let the floor drain of the balcony discharge washing water. It is not that the property deliberately makes things difficult, but that the overall environment is not polluted by chemicals. Therefore, when decorating, we must first find out whether the balcony has a sewage pipe interface, and then design the location of the washing machine to avoid putting the washing machine on the balcony without a sewage pipe interface.
