OmanUnpredictable weather patterns in the UAE require infrastructure projects to be prepared for sudden and intense rainfall. Effective rainwater management and dewatering solutions are essential to protect critical infrastructure and ensure construction work continues without interruption.
Khansaheb Sykes recently delivered a high-capacity rainwater management system in International City, Dubai, designed to protect a major infrastructure project from sudden flooding and stormwater accumulation. The project required a reliable temporary pumping solution capable of responding immediately to heavy rainfall while maintaining safe operating conditions across the site.
By combining advanced pumping equipment with expert on-site support, our team implemented a robust flood mitigation and dewatering strategy that ensured both immediate flood protection and long-term operational readiness.
Overcoming the Primary Environmental Challenge
The core challenge of this six-month project was the site’s dependence on sudden weather events that can generate significant volumes of rainwater in a short period. On this project, the site required a rapid flood response system capable of handling fluctuating rainfall while protecting the surrounding MEP network and infrastructure.
Several operational factors influenced the solution:
- Rapid rainfall response
The pumping system had to activate immediately when heavy rainfall occurred. - Continuous standby capability
A dedicated emergency response team was required to ensure the system remained ready at all times. - Urban site constraints
The infrastructure project was located in a busy city environment, requiring low-noise equipment and minimal disruption to nearby communities.
To address these requirements, Khansaheb Sykes’ team developed a responsive rainwater management system capable of supporting both emergency pumping and long-term stormwater control.
Engineering a Strategic Pumping System
To manage rainwater effectively, our dedicated experts designed a multi-tiered pumping solution connecting local drainage points directly to the main discharge network.
Our team deployed a fleet of 30 high-performance pumps across the site to ensure efficient water movement and continuous drainage.
High-Volume Management
We utilised 5 Super Wispaset 300 pumps for high-volume water displacement in noise-sensitive areas. These units are capable of delivering flows of up to 415 l/s, featuring a 480-litre fuel tank for up to 24 hours of autonomous operation.
Versatile Over-pumping
15 × GP 150M pumps delivered reliable general-purpose dewatering for continuous site drainage.
These pumps can deliver flows of up to 90 litres per second with a maximum head of 38 metres.
This makes them well suited for moving large volumes of stormwater efficiently across construction sites.

1 × GP 200 and 2 × GP 200M pumps supported high-capacity water transfer across the site.
These pumps transfer large volumes of water efficiently, making them ideal for rainwater management and stormwater control during heavy rainfall events.
Specialized Flow Control
5 × WP 150/60 pumps maintained stable water flow and discharge control.
Designed specifically for high-performance dewatering, the pump can handle large volumes of water while maintaining stable flow rates, making it ideal for rainwater management and stormwater control on large sites.
2 × MH 150 pumps enabled water transfer across higher elevations.
These pumps handle high-head requirements efficiently. They move water across greater elevations or longer discharge distances on infrastructure sites.
Our engineering team expertly integrated these specialized units to manage the suction and discharge cycles simultaneously. This balanced setup ensured that even during peak rainfall, the system maintained optimal pressure to prevent backflow and site flooding.
Delivering Long-Term Resilience and Results
The implemented pumping system successfully managed the initial phase of rainwater mitigation, ensuring the site remained operational and protected during rainfall events.
Key results included:
| Environmental Impact | All accumulated rainwater was drained, preventing flooding and protecting surrounding infrastructure. |
| Project Continuity | By maintaining a dry site, infrastructure works proceeded without flooding delays. |
| Verified Reliability | The system will remain operational on-site until May 2026 to handle future seasonal cycles. |
The client confirmed that the project successfully achieved its objectives while protecting the surrounding infrastructure. Due to this success, the project will continue to provide security against weather fluctuations through the upcoming seasons.

FAQs
What is the benefit of a “super-silenced” pump in a city area?
Super-silence pumps like the Super Wispaset 300 operate at low decibel levels (approx. 66 dBA). These units are capable of delivering flows of up to 415 l/s, featuring a 480-litre fuel tank making them ideal for 24-hour operation in residential areas without causing noise pollution.
Why are different pump models used together in a hierarchy?
A mix of pumps allows us to scale drainage capacity based on specific manhole volumes, ensuring the most efficient performance across the entire site.
How often is the equipment inspected?
We perform regular proactive inspections by our service team to verify that all units are operational and ready for immediate action if weather patterns change.
How long will the pumps remain on-site?
The current mitigation plan is scheduled to continue until May 2026 to ensure the area remains protected through multiple seasonal weather cycles.
