He said the number of sewage trucks in the city will continue to decline as the project ends in 2015. “Sewage trucks will no longer be roaming the streets of already-connected neighborhoods. The final stage will start in 2015 and it will connect 30,000 buildings to the underground network in neighborhoods south of Jeddah,” he said. Al-Assaf said 23,000 houses had been connected to the network so far with another 17,000 set to be connected in Al-Faisaliah, Al-Rawdah and other districts. Currently, work is under way to install the main sewage pipe lines before additional homes can be connected to the system.
