Work on the sewage network in Al Gharrafa, serving about 3,190 plots in the area, have been completed, Ashghal said.
The network covers an area of more than 5,860,000sqms.
All houses in the project area are now connected to the network. The project included building a sewage network in Zone 51 which comprises Al Gharrafa, Al Nasiriyya, Izghawa, and Bani Hajer, which all fall under Al Rayyan Municipality.
The project also covers Zone 71 consisting of Al Kharaitiyat, and Umm al Amad, which are under Umm Slal Municipality. The sewage network is 10 km away from the north-western side of Doha.

Engineer Ali Ibrahim Ashkanani, head of north areas section at Roads Projects Management Department in Ashghal, said that with the completion of the advanced sewage system in the area, which is connected to Pumping Station 70, the use of septic tanks will be eliminated and a permanent sewage network will be available.
The technical works of the project included laying about 65 km of durable and high quality main sewage pipes, made of environmentally friendly materials, in addition to building 2,360 concrete manholes. 
Ashkanani said any completed project stays under warranty for 400 days, during which the contractor makes any required changes or maintenance, and this is a standard thing in all Ashghal’s contracts. 
The construction of the sewage network in Al Gharrafa was implemented by Oasis for Trading and Contracting at a cost of about QR200mn.
It is one of the Local Areas Infrastructure programme projects, which covers all areas of Doha, main cities and external areas in Qatar. Through this programme the authority develops roads and infrastructure and implements specialised projects to develop and upgrade sewage and drainage networks.
