Sewage system Rashdiya, Iraq
Client
Governorate of Baghdad
Project
A sewer system was designed for villages in the vicinity of Rashdiya commissioned by the Governorate of Baghdad. These areas had no previously existing sewage system. Additionally, there is no a waste water treatment plant. The sewer design provides for the construction of a waste water sewer, rainwater sewer and the construction of a sewage treatment plant. Other challenges in the design included the elevated terrain and the limited number of available pumping station locations. The lack of drains with sufficient capacity constituted yet another hurdle.
The design for the waste water system consists of six separate basins, each with its own pumping station. The pumping stations discharge via a combined pressure pipeline system onto a collective pipe. This pipe has diameter of 1000 mm, is approximately four kilometres long and is connected to the designed waste water purification plant. The discharge pipe system is designed in such a way that so that the pumps stations pump through the desired flow in the single loop as well as the entire collective loop cases.
Due to insufficient water surface, rainwater is also pumped through. Each pumping station is to be equipped with a rainwater compartment. The individual pressure pipes discharge into the River Tigris. To absorb peaks in the rainfall, the specially designed collection systems can store large amounts of water. The pump capacities can therefore be relatively limited.
The completed drainage systems have been developed in detail and have been prepared for tendering.
