Completion of Refurbishment and Upgrading of Four Sewage Pumping Stations in Doha

10/18/2021

Increasing the capacity of pumping stations in New Slata, Al Mansoura, Al Messila, and Al Rayyan

As part of its continuous efforts to provide sustainable solutions to improve the country’s sewage networks according to the best International standards, the Public Works Authority ‘Ashghal’ announced completion of the Refurbishment and Upgrading Works for Four Sewage Pumping Stations Project.
The project aimed at increasing the capacity of four pumping stations located in vital areas within Doha, namely New Slata, Al Mansoura, Al Messila, and Al Rayyan, between 61% and 212%, in order to accommodate current and future sewage flows within these important areas, and to cope with the future development and population growth.
On this occasion, Eng. Shouq Ibrahim, from the Drainage Networks Projects Department at Ashghal, stated that the project was designed to ensure the preservation of the environment, as all the pumping processes are done according to the environmental assessment standards.
Eng. Shouq explained that three of the four pumping stations had a dramatic increase in their ability to accommodate and pump the sewage flows. The New Slata Pumping Station’s capacity has increased by approximately 61%, allowing around 8,600 m3/day to be pumped instead of the previous 5,300 m3/day. The Al Messila Pumping Station's capacity has increased by approximately 212%, allowing 14,000 m3/day to be pumped instead of 4,500 m3/day. The Al Rayyan Pumping Station’s capacity has increased by 161%, to pump around 4,700 m3/day instead of 1,800 m3/day.
Eng. Shouq added that the upgrade works at the fourth pumping station, located in Al Mansoura, included installation of new equipment and construction of a new OCU (Odour Control Unit) to enable more efficient operations and to prevent bad Odour at this location, as well as maintaining and upgrading of the MCC (Motor Control Center) and PLC (Programmable Logic control) SCADA system. Moreover, the GRP pipeline rising main was replaced with approximately 60m of Ductile main. 
In addition, the project included the decommissioning of Ras Abu Abboud Pumping Station, and which was replaced with a new gravity sewer line.
Ashghal was committed to ensuring the implementation of all health and safety requirements for workers, operators, and the public throughout the project period. It is also worth mentioning that Ashghal achieved this great milestone with approximately 750,000 man-hours with Zero LTI.
As part of Ashghal’s keenness to support local manufacturers, many locally manufactured materials were used in the project, such as concrete, reinforced steel, precast manholes, GRP “glass reinforce plastic” pipes and ducts, GRP tanks, UPVC “unplasticized polyvinyl chloride” pipes and conduits, and RC jacking pipes “concrete pipes”.
The project was implemented by Contracting Services & Trading Company (GEC), under the supervision of KEO International Consultants.
