The ongoing refurbishment and upgrading works of sewage pumping stations by Public Works Authority (Ashghal) are expected to develop Qatar’s sewage network into international standards, it was announced yesterday. 
The works are being undertaken at New Salata, Al Mansoura, Al Messila and Al Rayyan pumping stations as part of Ashghal’s efforts to provide the country with sustainable solutions in treating sewage. 
The aim is to increase the capacity of pumping stations in order to accommodate both current and future sewage flows within these four important areas to meet the demand in accordance with the future development and the expected population growth.
The ongoing renovation works include installation of new equipment to improve the pumping stations’ performance and functions, upgrading of pumping stations’ control systems including new telemetry systems, improved fire alarm and suppression systems and new instrumentation. This is in addition to installing new improved odor control systems to prevent or reduce bad odors in the surrounding areas.
Engineer Ali al-Anzi from the Drainage Networks Projects department of Ashghal said the works at three of the four pumping stations will ensure a remarkable increase in their ability to accommodate and to pump sewage flows.  
The capacity of New Salata pumping station will be increased by approximately 62% allowing around 8,600 cu m per day to be pumped instead of the current 5,300 cu m per day. The capacity of Al Messila pumping station capacity will be increased by approximately 211% allowing 14,000 cu m per day to be pumped instead of the current 4,500 cu m per day. The Al Rayyan pumping station’s capacity will be increased by 161% allowing pumping of around 4,700 cu m per day instead of the current 1,800 cu m per day.
Al-Anzi added that the upgrading works at the fourth pumping station, located at Al Mansoura, include installation of new equipment and constructing a new Odour Control Unit (OCU) in a bid to enable more efficient operations and to prevent bad odor at this location.
Apart from renovating the four pumping stations, the ongoing refurbishment and upgrading works also include decommissioning of Ras Abu Abboud pumping station that will be replaced with a new gravity sewer line. The project, being implemented by Contracting Services and Trading Company, is expected to be completed in the second quarter of 2021. During the implementation, Ashghal is also supporting local manufacturers by making use of locally made materials such as concrete, reinforced steel, precast manholes, Glass Reinforced Plastic (GRP) pipes, and ducts, GRP tanks, Unplasticised Polyvinyl Chloride pipes, and conduits and Reinforce Concrete jacking pipes. 
Ashghal has ensured that these pipes meet the required quality standards and qualifications for the implementation of the project.
Further, the project is designed to ensure the preservation of the environment as all the pumping processes will be carried in accordance with the environmental assessment standards. Ashghal is also committed to ensuring the implementation of all health and safety requirements for workers, operators and the public throughout the project period.
