Turning the Tide on Site Water: Reducing Fresh Water Demand

With Water Saving Week 2026 (May 4th – 8th) upon us, there is no better time to look at how we manage one of Earth’s most vital resources. This year’s campaign theme is Protect Water for Wildlife, highlighting the direct link between the water we use and the health of our local rivers, lakes, and ecosystems.

 

In heavy-duty sectors like construction, concrete production, and quarrying, water is the lifeblood of the site. From batching new concrete to washing out mixer trucks and keeping dust down, the daily demand for fresh water is staggering. At the same time, these processes generate vast amounts of heavily silted, highly alkaline wastewater.

 

But what if you could close the loop and drastically shrink your freshwater demand while actively protecting the waterways that local wildlife depends on? By combining robust pumping with intelligent treatment, you can turn a waste product into an operational resource. Here is how Atlantic Pumps is helping sites achieve exactly that.

 

 

Step 1: Divert & Capture; Sumps & Submersible Pumps

 

The first step to saving water is making sure you don’t lose the water you already have onsite. Sites naturally accumulate large volumes of grey water, surface water run-off, and truck washdown wastewater. Historically, this slurry was a headache, often requiring expensive tankering off-site.

 

To reclaim this water, it must first be captured and transported reliably. This is where Audex submersible pumps step in. Designed specifically for the harshest, most abrasive environments, Audex pumps excel at handling sediment-heavy, challenging liquids. Whether it is clearing out a settlement lagoon or wedge pumping from a truck washdown sump, or managing heavy surface water run-off after a storm, Audex pumps efficiently transfer this dirty water to the treatment stage without clogging or failing.

 

 

Step 2: Treat and Restore with EnviroHub

 

In a system that can be completely automated, Audex pumps fire up when sump levels rise, transferring the contaminated water to an EnviroHub treatment system. EnviroHub is a modular system, allowing the ideal configuration to be built for sites large or small.

 

EnviroHub takes the complex science of water treatment and packages it into a practical, automated system built for the demands of construction sites and quarries. Using the EnviroHub concrete washout module, alongside its advanced treatment units, the system restores the water quality through a highly efficient, three-step process:

 

Coagulation: Specially dosed chemicals are introduced to destabilise the suspended solids (like cement dust and silt) in the water, prompting them to start clumping together.

 

Flocculation: The system then gently agitates the water, encouraging these tiny clumps to bind into much larger, heavier particles known as ‘flocs’.

 

Settlement: Finally, the water moves into settlement units. The heavy flocs drop to the bottom as sludge (which can be easily removed and safely disposed of), leaving clear, treated water behind.

 

Crucially, the EnviroHub system also continually monitors and corrects the pH levels, neutralising the dangerously high alkalinity typically found in concrete wash water.

 

Connected remotely to the online software Senteos, managers can access live and historical data – ideal for auditing efficiency and providing proof of compliance.

 

 

Step 3: Reuse or Replenish

 

Once the water has passed through the EnviroHub system, you are left with high-quality, pH-neutral water. This is where the double benefits come together; not only is the environmentally damaging wastewater made safe – the closed-loop system slashes the demand for fresh water.

 

Instead of constantly drawing from the mains or local boreholes, you can now reuse this treated water directly on site. It is perfect for:

 

• Making fresh batches of readymix concrete.
• Feeding site-wide dust suppression systems.
• Washing down vehicles and plant machinery.

 

Alternatively, if your site has a surplus of treated water, it is now safe, clean, and fully compliant for consented discharge. Instead of posing a pollution risk, this clarified water can be safely released to replenish local waterways. This directly supports the Protect Water for Wildlife initiative, ensuring that our rivers and streams maintain healthy flow levels without being exposed to harmful sediments or pH spikes.

 

 

A Smarter Way to Save Water

 

Water Saving Week is the perfect prompt to evaluate how your site handles its water cycle. By combining the rugged, dependable pumping power of Audex with the intelligent treatment capabilities of EnviroHub, you can protect the local environment, maintain strict compliance, and drastically reduce your operational fresh water costs.
