Abstract

The pumping stations are responsible for pumping of treated water or sewage. These structures are essential for a system of water supply that does not have a position to have their supplies from a totally gravity system. The city of Jundiai (São Paulo - Brazil), basis for study, has 28 (twenty eight) pumping stations distributed throughout urban areas and may be responsible for environmental degradation through the noise, because the motor-pump these stations generate noise, sometimes, audible over long distances. Noise, depending on the level and duration, can result in psychological disorders or physiological changes associated with stress reactions, fatigue, irritability and poor concentration. This work had as main purpose to characterize the pumping stations about its constructive aspects of enclosure for the joint motors and pumps (noise sources). Measurements of sound pressure levels inside and outside the station, with the motors and pumps on and off, according to standard NBR 10151/2000 (ABNT), were did to obtain data showing sound insulation that pump station provided to noise generated by motor-pump. The different deployment configurations of building systems and arrangements of openings resulted in different acoustic performances, some attending the standards and not others. Therefore evaluated if their impacts on the surrounding sound and the station were drawn up some suggestions of strategies for mitigation of impacts (AU)
