About EvapCo: Australia’s Evaporation Management Specialists

About Evapco

At Evapco, we’re all about helping Aussies hang on to the water they’ve worked so hard to collect.

Whether you’re managing a farm dam, a rural property, or a large storage, we know how quickly evaporation can take its toll — and we’re here to stop that.

Evap.co was created out of Big Ditch, a trusted name in dam building and water security for more than thirty years. We’ve spent decades digging, shaping, and securing the dams that keep regional Australia running, so we know exactly what it takes to protect your water.

Backed by that experience, we’ve turned our focus to smarter, simpler ways to cut evaporation losses and stretch every megalitre further.

At Evap.co, we combine practical know-how with proven solutions to help you keep more water where it belongs — in your dam.

From hands-on advice to innovative products, we’re here to make managing your water easier, more efficient, and built to last.

Our Expertise

EvapCo was created from Big Ditch, one of Australia’s most experienced dam construction companies with more than 30 years operating across New South Wales, Queensland, and Victoria. That hands-on background means we understand water storage from the ground up — literally.

We’ve spent decades digging, shaping, and securing dams for farmers, miners, and infrastructure operators across regional Australia. Now we’ve turned that expertise toward a problem that costs Australian water users billions of litres every year: evaporation.

What We Do

EvapCo specialises in evaporation management solutions for:

• Farm dams and rural water storages
• Mining and resources sector process water ponds
• Power generation and industrial water storages
• Municipal and infrastructure water reserves

Our solutions include modular shade ball covers, floating dam covers, suspended shade structures, and custom-engineered evaporation control systems. Every solution is designed specifically for Australian conditions — the UV intensity, wind patterns, temperature extremes, and water quality challenges that overseas products often fail to account for.

Why Evaporation Matters

Australia loses an estimated 750 billion litres of stored water to evaporation every year from approximately 50,000 farm dams and open water storages. For the average farm dam, that’s around 15 million litres per year — gone. For mining operations and major infrastructure, the losses are even larger.

We believe that with the right technology and advice, most of that water can be kept where it belongs: in your dam.
