Project Description.

As Mansoura’s urban population expanded in the 1960’s, 1970’s and 1990’s, mechanical pumping stations were constructed to tackle the increase in wastewater effluent.

However, pump failure in one of the stations mentioned below led to wastewater overflow on the streets of the highly populated Mansoura city; these stations were:

• El Moroor Station

• Mansoura Stadium Station

• International Hospital station

The aim of the project was to replace the mechanical pumping stations mentioned above with a single gravitational flow network in order to reduce electrical power consumption and operational costs.

The new network led to zero downtime and was able to withstand extremely high flowrates up to this day without the need for mechanical pumping mechanisms.

Scope of Project.

The project involved drilling, supply and installation of three pipelines connected in series over a distance of 2 kilometers with diameters ranging from 500mm to 900mm.

Trenching and digging works were executed in order to reach 11 meters of depth in extremely narrow streets surrounded by high story buildings.

This was a site element which presented extremely high risks and was overcame by restricting the sides of trenches with steel support structures to maintain the structural integrity of these buildings.

 Fun Fact: The support structures are still present up to this day!
