Prepare Construction Sites for Winter Flood Water with the Right Drainage Pumps

Forecasts of severe weather during winter 2026/27 are a timely reminder that unwanted water can quickly become more than an inconvenience. Heavy or prolonged rainfall can flood excavations, basements and plant areas, restrict access, delay trades and, in more serious cases, threaten equipment and completed work.

Having suitable drainage pumps available before bad weather arrives can help construction companies react quickly rather than trying to source equipment after a site has already flooded. DAB Pumps offers a choice of compact submersible drainage pumps suited to removing unwanted water in different site conditions, including the VERTY NOVA, NOVA and NOVA UP ranges.

Confined spaces
Space is often at a premium when water gets where it shouldn't. The VERTY NOVA is designed for drainage applications where conventional pumps can be difficult to position, making it particularly useful for restricted spaces.

Its compact design and integrated float make it suitable for narrow drainage wells and other locations where there is limited room for a traditional external float to operate. On a construction project, that could mean dealing with water collecting in a confined basement sump following several days of rain, draining a restricted plant area or responding to water ingress in a location where there simply isn't sufficient space for a larger pumping arrangement. VERTY NOVA can also pump down to a low residual water level, helping contractors remove more standing water before final clean-up.

For more general drainage duties, DAB's NOVA range provides a robust submersible solution for pumping clear water or rainwater. A familiar winter scenario is an excavation that is dry when a site closes on Friday afternoon but contains a significant volume of rainwater when the team returns on Monday morning. Until that water is removed, groundwork, concrete preparation or other activity may have to wait.

Similarly, temporary drainage arrangements can become overwhelmed during intense rainfall, leaving standing water around compounds, access areas or unfinished structures. Keeping an appropriate NOVA pump available gives site teams a straightforward means of tackling these situations and helping work resume.

Different models within the NOVA range allow the pump to be selected according to the required performance and application rather than relying on a one-size-fits-all approach. Standing water does not always need to be deep to cause a problem. Even a relatively shallow layer can prevent follow-on trades from starting, create difficult working conditions or extend drying and clean-up times.

DAB's NOVA UP has been developed for applications where low-level drainage is important. Its ability to pump water down to a very low residual level makes it particularly useful when contractors need to clear floors and other flat surfaces following water ingress.

Consider a partially completed basement or ground-floor area where overnight rainfall has entered before the building envelope is fully watertight. Removing the bulk of the water solves only part of the problem if a shallow layer remains across the slab. A pump capable of low-level suction can make the subsequent clean-up considerably easier.

“Winter resilience on construction sites is often built around relatively simple preparations. Checking temporary drainage routes, keeping gullies and channels clear and identifying where water is most likely to collect can all reduce the impact of severe rainfall. Pumping equipment should form part of the same planning process. Contractors can assess likely water volumes and pumping heads, identify suitable discharge points and ensure pumps, hoses and power supplies are ready before they are needed,” says Adam Ferneyhough, Country Director for the UK & Ireland at DAB Pumps.

“Preparing now could make the difference between arriving after severe winter weather to find an inconvenient pool of water and finding a problem that brings work to a halt.”
