What are the types of building health facilities?
What is a consumer water supply system?
Supplying and distributing water for purposes such as drinking and washing can be considered as the main use of building sanitary facilities. Like other municipal services, drinking water is transferred to the building through the piping systems inside the street. The water pressure in the urban plumbing system is about 2.5 to 5 bar. Inside every building, there is a water meter with a shut-off valve, which allows the water to be cut off while controlling the consumption. Of course, an emergency shut-off valve is also installed in the place where the pipe branches from the main system into the street or alley. Water supply piping is divided into two cold and hot water systems.
What is a water and sewage discharge system?
After using water for various purposes, the waste water should be transferred outside the building. In most residential buildings, ABC, PVC and cast iron (CI) pipes are used for draining sewage. These pipes are connected to all sanitary appliances in the building, such as toilets, bathrooms, sinks, etc. When using sanitary appliances and washing, water flows inside the pipes.
3. What is a sewage ventilation system and how does it work?
In order to ensure the proper functioning of the sanitary facilities of the building and its accessories, the drainage system of the building must be well ventilated. For example, when you use a toilet tank flush to flush out the sewage, the effluent moves to the outside. This movement creates a negative pressure behind the drain. The sewage ventilation system, by adjusting the pressure in the piping network, prevents the sewage from getting stuck in the pipes and the return of toxic gas resulting from it into the building.
4- What is a rainwater piping?
In the past, rainwater was transported through the building's sewage piping system, along with sewage, to the municipal sewer network. Today, in order to improve water management, the rainwater disposal system is separated from the sewage disposal system. In this way, when it rains, the water is directed around the building by the gutters on the roof. It is also possible to store rainwater for non-drinking purposes such as watering plants. Of course, in some cases, rainwater is connected to the urban rainwater collection network by a gravel drainage system. The problem of this method is the possibility of flooding of roads during heavy rains.
