Site Drainage Contractor Pumps
If you work in construction or are a contractor, reliable and durable water pumps are essential for site drainage and various tasks on-site.
Construction sites often face issues such as flooded trenches and foundations, high water tables, and waterlogged conditions due to rain, which can halt work and lead to costly delays.
Using a site drainage pump can help keep these areas dry, allowing construction to continue without interruption. When excavating, groundwater or rainwater often fills trenches and excavations, obstructing progress. Site drainage pumps can be used to remove this water, enabling work to proceed. They are also useful for dewatering ponds, rivers, or streams with cofferdams to create dry work areas for maintenance or construction projects.
What is Different about a Site Drainage or Contractor Pump?
Site drainage pumps are specially designed to handle dirty water and high flow rates, ensuring rapid and effective drainage. Standard submersible pumps are not designed for the harsh conditions a construction site would pose, and thus this range are designed to be ultra hardwearing with resistant impellers and robust bodies. You can even select a pump with a built-in agitator, such as the EVAK Trenchman, to make light work of water with significant suspended solids.
Contractor Pumps
Due to the very nature of their use on a construction site, contractor pumps have to be robust.
Popular Contractor Pumps Include:
The TSURUMI LB series to powerful engine-driven options such as the Drymax pump, these pumps suit a range of needs, including hire fleets, utilities, and waste removal.
The Stream SPK450A series of water pumps from Stream are the ideal solution if you are looking for heavy duty pumps for submersible site drainage. These small, and sturdy contractor pumps come with a 2-year manufacturer guarantee, ensuring you get your return from your investment, and peace of mind that once you buy your Stream water pump, you will have a high-quality product, that is built to last.
The Trenchman range by Evak are designed for arduous site drainage applications and dewatering. They are ideal for use on construction sites, or to drain large areas of water. The pumps are fitted with a Hytrel coated steel impeller for abrasion resistance, and they come with an in built agitator as standard.

Engine Driven Contractor Pumps
For remote sites without available power sources, engine-driven pumps are ideal. These pumps can also be essential for flood prevention, pumping water away to reduce flood risk and protect against damage. The most popular model due to its robustness and ease of use is the Drymax Water Pump. The Drymax pumps are perfect for site pumping with liquids that contain sludge, mud, sewage, sand and suspended spherical solids that go up to a maximum of 40mm.
Our range of construction pumps covers everything from electric to engine-driven models, each carefully selected for value, reliability, and effectiveness.
