Qatar’s Public Works Authority (Ashghal) is on schedule with a project to increase the capacity of four sewage pumping stations by 62 per cent to 211 per cent in order to accommodate both current and future sewage flows.
The pumping stations are located in vital areas within Doha, namely New Slata, Al Mansoura, Al Messila, and Al Rayyan.
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.
Ali Al Anzi, from the Drainage Networks Projects Department at Ashghal, stated that three of the four 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.
The New Slata Pumping Station’s capacity will be increased by approximately 62 per cent, allowing around 8,600 cu m per day to be pumped instead of the current 5,300 cu m per day.
The Al Messila Pumping Station's capacity will be increased by approximately 211 per cent, 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 per cent, to pump around 4,700 cu m per day instead of the current 1,800 cu m per day.
Ali Al Anzi added that the upgrade works at the fourth pumping station, located in Al Mansoura, 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.
The project is being implemented by Contracting Services & Trading Company (GEC), and is expected to be completed in Q2, 2021.
