Abstract

Water distribution systems and failure to prevent the formation of burst are studied. Bursts occur in distribution systems because of poor workmanship and material defects, traffic load, rupture from earthquake, soil corrosion and high pressure. Planning stage creates negative effects due to pressure. To eliminate pressure on the network, average of 30 to 60 and 20 to 80 mws should be applied critically. However, in some cases the provision of these terms is very difficult. Slope more than that cannot be done in cases of separation. There should be need to think of different options. In such cases, the pressure within the network itself as part of high pressure in the left districts reduced pressure through a valve to bring the appropriate pressure. City of Adapazari network in accordance with the regulations of Province Bank is divided into two floors: high regions of city where Maltepe and Hizirtepe districts get water from the tower tank. Hizirtepe malfunctioning occurred due to complaints from high pressure gradient. As a result of increased water loss, the complaints of subscribers and business costs are increasing. A specific point of pressure measurement made at the highest pressure to be right enough pressure has been reduced. After implementation, there has been a huge drop in the number of bursts. The idea of water tower supplying water to the region by using two pumps is promoted. Before and after application, pump runtime is compared. Daily average working time of two pumps for the water given to the distribution system decreases from 26 to 22 h, despite increase in temperature and seasonal decline.

Key words: Distribution system, pump, repair, leakage, water loss, pressure management.
