COMMERCIAL WATER TANK SOLUTIONS FOR NZ BUSINESSES.
Tanksalot® corrugated steel water tanks are designed for large-scale rainwater harvesting and stormwater retention across commercial and industrial sites.
Scalable water storage and management.
We manufacture water tanks specifically designed for high-volume stormwater detention and retention, helping businesses, developers, and infrastructure projects comply with council regulations while managing runoff effectively.
High-volume stormwater detention and retention tanks.
Our detention tanks reduce peak flow during heavy rain events, easing pressure on stormwater systems, while our retention tanks allow for on-site water reuse. All of our tanks are compatible with local authority specifications throughout New Zealand.
Rainwater harvesting for business efficiency.
Collecting and reusing rainwater is a smart move for businesses looking to reduce operating costs and minimise their environmental impact. Our commercial water tanks make it easy to implement rainwater harvesting systems for landscape irrigation, vehicle washing, or greywater systems. It’s a sustainable solution that saves money and supports business ESG goals.
Market-leading 10,000L Slimline water tanks.
We construct our Slimline tanks up to an impressive 10,000-litre capacity, whereas most slim tanks on the market max out at 5,000 litres. For higher-volume sites, multiple tanks can be linked together while maintaining narrow footprints, making these tanks ideal for boundary lines or tight spaces.
Strong, sustainable and beautiful industrial water tanks.
Built with AQUAPLATE® steel, our tanks are made to last with minimal upkeep. Unlike plastic tanks, steel won’t degrade in UV light and holds its shape even when empty. It’s a smart long-term investment for businesses wanting a dependable water management solution.
Seismic restraint system for compliance and safety.
We offer a standard and heavy-duty Slimline water tank restraint solution, compatible with a generic PS1. We’ll work with you to provide site- and project-specific solutions tailored to meet your requirements.
Custom-made to suit your commercial property project.
Every site is different, which is why we offer custom-made options and configurations tailored to your commercial project. Whether you need a large-capacity detention tank, a stormwater management system, or tanks to fit tight footprints, we can help. Contact our team to find the ideal solution.

FAQ's
Why do you use corrugated steel?
We choose corrugated AQUAPLATE® steel as we believe it delivers the best possible water storage solution. Our corrugated steel water tanks do not contain BPA or UV stabilisers. Using steel allows us to custom make any tank to meet your specific needs. Steel also offers superior strength, fire resistance, and can be fully recycled. As experienced and trusted water tank manufacturers, we’ve found this material offers the best balance of durability, safety, and sustainability.
How do I choose the best water tank for my needs?
Selecting the best option for your property depends on your available space, usage requirements and local regulatory requirements. Our team can assess your needs and help you find the ideal solution. We recommend considering:
- Proposed tank location
- Physical space constraints
- Daily water consumption needs
- Intended use (drinking water, garden irrigation, etc.)
- Local rainfall patterns
- Budget and installation requirements
- Local Council stormwater attenuation/detention requirements
What is the difference between a retention tank and a detention tank?
A retention water tank is designed to capture and store stormwater runoff for later use. It retains the water on-site, preventing it from immediately entering the drainage system. This stored water can be used for irrigation, landscaping, or other non-potable purposes, contributing to sustainable water management practices. Retention tanks help reduce the demand on municipal water supplies and mitigate the impact of urban development on local water resources.
A detention water tank is primarily focussed on controlling the flow and release of stormwater to prevent flooding and erosion. Detention tanks temporarily hold and slowly release stormwater into the drainage system at a controlled rate. This helps manage peak flows during heavy rainfall, reducing the risk of downstream flooding and erosion.
What is the lead time on water tanks?
We can turn around your tank order in 7 to 10 working days, excluding delivery. Contact us to discuss your requirements and we will confirm your lead time.
Where do you deliver and how much does it cost?
We deliver tanks to metropolitan Auckland for free and can arrange nationwide delivery. Contact us to discuss your requirements and we will prepare an estimate.
What is a seismic restraint?
Seismic restraints are designed to secure water tanks and prevent them from tipping, sliding, or overturning during an earthquake. The ground shaking during seismic events can pose a significant risk to the stability of structures, including water tanks, and securing them is essential to ensure public safety and the integrity of water supply systems. Seismic restraints also help minimise the risk of damage to the tank itself and reduce the potential for water contamination or loss.
