Temporary
Pumping

What is temporary pumping?

Temporary pumping is the installation of a complete system of pumps, piping, and accessories to move water temporarily on a construction, rehabilitation, or emergency site. Unlike permanent systems, temporary pumping is designed for rapid deployment, operation over a set period, then full removal without leaving permanent infrastructure.

Durax handles the entire process: site evaluation, hydraulic system design, pump and HDPE piping supply and installation, commissioning with flow testing, continuous monitoring via PumpWatch, and full demobilization at project completion.

Common Applications

Our temporary pumping systems are used in a wide variety of field applications:

• Watermain bypass during replacement or repair of municipal networks. The system maintains potable water supply throughout the duration of the work.
• Sewer bypass to allow rehabilitation work without service interruption. Continuous wastewater pumping with 24/7 monitoring.
• Excavation dewatering to allow crews to work dry in trenches and foundations.
• Emergency pumping for pipe breaks, flooding, or unforeseen situations requiring rapid response.
• Transfer pumping to move large volumes of water between basins, rivers, or reservoirs for environmental or industrial projects.
• Mine pumping for groundwater control in open-pit and underground mine shafts and galleries.

Our Turnkey Approach

Durax acts as a field partner for equipment rental companies, general contractors, and municipalities. We handle the specialized aspects of temporary pumping: hydraulic system design, on-site HDPE piping installation and fusion, complete commissioning with flow and pressure testing, and continuous monitoring via our PumpWatch service in remote or field mode.

This integrated approach simplifies coordination on the jobsite and ensures the system operates as a cohesive whole, from the first fused joint to the last monitoring alert.

Types of Installations

Our temporary pumping systems are configured to the specific needs of each jobsite:

• Self-priming centrifugal pumps — diesel or electric, ideal for medium and high-flow pipe bypass, including jobsites without power supply and remote operations
• Submersible pumps — for deep excavation dewatering and restricted-access applications
• On-site fused HDPE piping — diameters from 2" to 24"+ based on flow requirements
• Variable frequency drives (VFD) — to optimize energy consumption and adjust flow in real time
