The ongoing refurbishment and upgrading work of four sewage pumping stations by the Public Works Authority (Ashghal) will be completed by the second quarter of 2021 remarkably increasing the capacity of the pumping stations in Doha. 
According to details, given by Ashghal, the capacity of the pumping stations will be increased by 62% to 211% in vital areas within Doha. As part of the project, upgrading and refurbishment works are carried at New Slata, Al Mansoura, Al Messila, and Al Rayyan, in order to accommodate both current and future sewage flows within these important areas, and to cope with the future development and the expected population growth.
The capacity of New Slata 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.
Refurbishment works include the installation of new equipment to improve the pumping stations’ performance and functionality with the upgrade of pumping stations’ control systems, including new telemetry systems, improved fire alarm and suppression systems, new instrumentation, among others. This is in addition to improved odour control systems to prevent or reduce bad odours in the surrounding areas.
The New Slata, Al Messila and Al Rayyan pumping stations will undergo a dramatic increase in their ability to accommodate and pump the sewage flows as opposed to the current capacity with the existing pumping stations and equipment.
Upgrade works at Al Mansoura pumping station include the installation of new equipment and constructing a new Odour Control Unit (OCU) to enable more efficient operations and to prevent bad odour at this location.
In addition, the project includes the decommissioning of Ras Abu Abboud pumping station to be replaced with a new gravity sewer line.
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.
