KSB Assists in Strategic Upgrading and Renovation of the Alexandria Sewage Pump Station in Egypt

To ensure the long-term functionality of existing infrastructure, Egypt's Alexandria Western Sewage Treatment Plant underwent a comprehensive upgrade. Pump manufacturer KSB supplied and installed two high-efficiency Sewatec SPN pumps with high power output.

The challenge lies in integrating the new pumps into the existing infrastructure, considering both the structural conditions at the site and the massive weight of the pump units. Since each pump weighs approximately 10 tons, conventional installation methods are impractical. Consequently, the pump units at the Alexandria plant were disassembled into volute and rear puller components, which were installed separately and then reassembled.

This pump delivers exceptional energy efficiency and reliability. With a maximum flow rate of 9,000 l/s and a head of approximately 100 meters, it operates at two speed settings powered by a dedicated motor. The adjustable speed configuration optimizes performance according to fluctuating hydraulic conditions. Manufactured at KSB's plant in Harle (Sarre) Germany, the two pumps were delivered within nine months.

The city of Alexandria, home to over 5 million residents, is served by Alexandria Sanitation and Drainage Company (ASDC) for its sewage treatment. The Alexandria West Wastewater Treatment Plant has a daily processing capacity of 462,000m³. With the commissioning of new pumps, the plant's inflow capacity has been significantly enhanced. The dual-pump design with shared pipeline channels ensures high operational reliability during wastewater treatment.
