"Sanitary Plumbing" and "Wastewater Plumbing" are plumbing systems that form the basic infrastructure of a building and lay the foundation of a healthy living environment. These systems ensure the safe disposal of used water and waste materials, as well as the provision, distribution and use of clean water in buildings. While plumbing regulates the flow of water within the building, waste water plumbing prevents the uncontrolled discharge of used water. Effective design, correct installation and regular maintenance of these systems not only protect the health of building occupants but also support environmental sustainability.
