Käyttövesikierto

Käyttövesikierto refers to the system of pipes and fixtures that deliver potable water for domestic use within a building and then remove wastewater. This encompasses both the hot and cold water supply and the drainage system. The supply side of the käyttövesikierto begins with the connection to the municipal waterworks or a private well, where water is treated to meet drinking water standards. It then travels through a network of pipes to various outlets such as faucets, showers, toilets, and appliances like dishwashers and washing machines. Pressure within the system is typically maintained by pumps or gravity.

The wastewater or drainage side of the käyttövesikierto is responsible for carrying away used water from these outlets. This includes greywater from sinks and showers, and blackwater from toilets. This wastewater flows through a separate system of pipes, often with a slight downward slope to facilitate gravity flow, to a main sewer line or a septic system. Proper ventilation of the drainage system is crucial to prevent sewer gases from entering the building and to ensure smooth drainage. The design and maintenance of the käyttövesikierto are essential for public health and the proper functioning of any building.
