Case Study: Qatar Reservoirs

EWFM Case Study - Qatar Reservoirs

Case Study: Qatar Reservoirs

Project Background:

In early 2021, EWFM was approached to provide a solution for drawing water/sewage from a reservoir in Qatar. The primary goal for the client was to establish a more sustainable approach to water management by recycling water rather than releasing it back into the sea. Given the scarcity of water in the arid climate of Qatar, this project was of utmost importance, especially with the upcoming World Cup. The success of the project hinged on EWFM’s contribution!


Environmental Concerns: The need to recycle water highlighted the environmental impact of disposing of water in the sea, and the challenge was to find a more responsible way to manage this resource.

Harsh Desert Conditions: The hot and arid climate in Qatar presented significant challenges in terms of material durability and system performance. The equipment needed to withstand these conditions.

Efficiency and Speed: The client required a solution that would expedite the recycling process, however avoiding both the scum which is gathered at the surface and the sediment collected at the bottom.

Waves: As pictured given the size of the reservoir the client needed something which could handle loads inflicted.

FRP Flange: The Floating Suction Unit had to join an FRP flange.  This meant that almost the whole unit has to be self supporting.

Solution: EWFM embarked on a comprehensive project that involved designing, manufacturing, and supervising installation of 5 x 40” Floating Suction Units.  These units played a crucial role in drawing water from beneath the reservoir’s surface while preventing the intake of sediment and scum. The units were manufactured in high-quality stainless steel construction, ensuring their durability in the tough desert conditions.

The five reservoirs that our floating suctions were needed for
Main Features:

Engineering: Before and during the manufacturing phase, our team dedicated extensive time to designing a solution that met the client’s satisfaction. This involved rigorous calculations, wave analysis, finite element analysis, and more.

40″ Pipework: The images themselves tell the story – these are the largest floating suction units we’ve ever produced. The presence of people in the images provides a clear perspective on the impressive size of these units.

Swivel Joints: The most intricate part of the project, the client even travelled from Qatar to witness a Factory Acceptance Test (FAT) at our facility. The Swivels were engineered to handle increased loads, featured special seals, and were equipped to withstand challenging environmental conditions.

Floats: These floats are meticulously designed to ensure stable flotation during operation, not randomly chosen.

Supports: The support systems played a crucial role, essentially carrying the entire unit. Of particular note is the support on the Swivel Joint, boasting an 8″ bore.

Testing: Both Swivel Joints and floats underwent pressure testing, with all major welds undergoing dye penetrant testing.

Supervision: Even after shipping 5 x 40ft containers to Qatar, our commitment didn’t stop. We ensured a supervisor was on-site to assist with the installation process.

Case Study: Qatar Reservoirs

After over a year of dedication, collaboration, and hard work from the entire EWFM team and their suppliers, the project successfully reached its milestone. The onsite inspection was passed, and 5 x 40” Floating Suction Units are now fully installed.

EWFM’s innovative approach, dedication to quality, and commitment to sustainable water management were key factors in the successful implementation of the Floating Suction Units for water recycling in Qatar. This project not only addressed a critical need in a water-scarce region but also showcased EWFM’s expertise in designing and delivering solutions tailored to challenging environments.
