FAQ's
Why install a rainwater tank?
With a Tanksalot® rainwater tank, you can enjoy reliable access to water, even during council restrictions or unexpected outages. Whether you’re watering the garden, filling the pool, or using your washing machine, our tanks provide a renewable and private water supply you can depend on throughout the year.
Collecting rainwater also helps to reduce stormwater runoff, protecting our waterways and decreasing demand for municipal water supplies.
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.
