What we do

Water treatment for the infrastructure sector

As the proven market leaders for responsive on-site wastewater treatment solutions for the infrastructure and construction sector, we develop and deploy packaged solutions tailored for each site and application. We select the best available technology from our extensive market-leading fleet, reducing excessive costs while providing the leading solutions in this competitive market.

Our highly flexible and readily deployable packaged solutions actively treat water to safely remove suspended solids, dissolved metals, and other contaminants – protecting you from environmental, financial, and reputational damage.

We specialise in ready-made plug-and-play packaged solutions of all sizes – from small single units and short one-off rentals for emergency or maintenance work to complete long-term treatment solutions for planned critical infrastructure works, all supported by our expert teams.

What we do

Some of our key infrastructure capabilities

Surface runoff

Excavation dewatering

Removing groundwater from excavations so construction can take place safely

Concrete washout

Using high-pressure water to remove damaged concrete, which produces wastewater with very high pH that must be captured and treated before discharge

Water re-use

Treating water so it can be recycled back into your system

Contaminated land / Remediation

Preparing, restoring, or cleaning contaminated land so it is safe and suitable for infrastructure construction

Hydro demolition and high pH neutralisation

The controlled collection and treatment of water used to clean concrete equipment to prevent highly alkaline slurry from entering drains or waterways
