Poseidon Water is a specialist dewatering and groundwater management contractor servicing civil construction, infrastructure and commercial development projects across Queensland, New South Wales and Australia. With almost 15 years of hands-on industry experience, we deliver engineered dewatering systems, mobile water treatment and total groundwater control solutions that keep excavations safe, dry and on program, even in the most challenging coastal and high-water-table environments.
We partner with builders, developers, and engineers to design, install, and manage deep-well, wellpoint, sump, and hybrid dewatering systems, supported by real-time monitoring and industry-standard methodologies that safeguard structural integrity and environmental compliance.
”At Poseidon Water, we don’t just pump water; we manage it responsibly.”
We understand the stringent environmental regulations governing dewatering discharge in Queensland, NSW, and Australia, and our treatment systems ensure groundwater meets the required disposal criteria before release. Our mobile treatment fleet includes lamella clarifiers, chemical dosing systems, tube settlers, and filtration and water quality monitoring to remove turbidity, adjust pH, and treat contaminants such as iron, manganese, hydrocarbons, and nutrients.
