Break pressure chamber (CRP) are small structures; its main function is to reduce the hydrostatic pressure to zero or the local atmosphere; generating a new level of water and creating a pressure zone within the operating limits of the pipes; There are 2 types; for the pipeline and distribution network. When long gap between the pickup and some points along the pipeline; above can be generated that can withstand high pressure pipe. In that situation; building cameras is needed breaks - that allow pressure to dissipate energy and reduce the pressure on zero (atmospheric pressure); in order to avoid damaging the pipe. These structures allow the use of small class lines; significantly reducing costs in the works of drinking water.
