Pumping units of water supply systems are the most important components of the engineering infrastructure of any building within the housing services and utilities system. They are engineering equipment located in the utility basement of the facility designed for forced water transport in the cold-water supply system or hot water supply system. The main operational problem of water supply booster pumps is transmission of impact on building structures through sound bridges, which subsequently results in a negative influence of noise on people inside the building. The present article gives overview of the problem related to structural noise protection. Authors offer the following mitigation method: elimination of sound bridges by means of installing damping tapes along the perimeter of the room where the equipment is installed. The given method is applied for reduction of noise from engineering systems on building structures. The existing technical solutions provide minimal noise reduction when two or water booster pumps with different operational frequencies are placed in the same room. The article presents results of a study conducted on the existing pumping house in a residential building with further implementation of damper tapes for noise protection. It allowed the elimination of sound bridges between building structures and water supply facilities in a residential building.
