In 1982 were developed plans and designs for the sewage network in the city of Samarra by a foreign company. This network included a system concerning the rotten water, and the separate system of rainwater disposal. The project started in 1989 but not the completion of the project so far, according to design plans That have been obtained, the network covers most of the region's ancient city of Samarra, with the exception of the al-Qattool, which was completed approximately (90%) of the network to date, the estimated length (55950) meters, This network works by gravity system in addition to one main pumping station pumps the sewage from the city’s network to the treatment plant. It is under construction so far. The sewage network is out of service in the city, because it is not connected to the treatment plant till now. It was illegally used by people by connecting the sewage of the residential buildings covered by the network, resulting in cases of rash and deposits in the heavy water in the city. In addition, the existing manholes built with a brick, and now need to rebuild and rehabilitate with reinforced concrete, as well as the completion of the network altogether. And because of the sewage network in the city stopped working, the ways of sewage disposal relied mainly on the septic tanks, and direct disposal in the streets of the city. The sewage is pumped by

special tankers, which unloading this sewage in open agricultural areas, and sometimes it is off in the pipelines of rainwater network that is essentially connected to the valleys surrounding the city and to the Tigris River. The rate of sewage produced a day, according to the Sewage Directorate in the city of Samarra, is estimated at (30) liters per capita, and this rate is unrealistic; the amount is supposed to be larger than this estimate. If we assume that this estimate is true, This amount of sewage can not be disposed of properly in light of the fact that if the sewage system has mentioned. Therefore, the bulk of this amount of water seeps into groundwater and polluted, in addition to polluting the waters of the Tigris and the general environment in the city, leading to environmental problems threatening the health of the inhabitants of the city of Samarra , add to the
