FAQ's
What’s an appropriate size for a home water tank?
The best-size water tank depends on your household’s needs and available space. For most Kiwi homes, we recommend starting with a 1,000 – 5,000L residential water tank for general use—this provides ample storage for garden irrigation, car washing, and basic household tasks. Consider our larger options to cover more substantial household needs, including laundry and toilet flushing.
For compact urban properties with limited space, a sleek 1,000 – 2,000L tank offers an excellent starting point while still providing meaningful water savings. During your home water tank consultation, we can help you calculate the perfect size based on your property size, water usage patterns, and available space.
Can I install a household water tank myself?
We recommend professional installation for water storage tanks for home use. If you wish to do it yourself, you’ll need a level, stable base—typically a concrete pad or compacted gravel surface—and basic plumbing knowledge to connect your tank to your home’s downpipes and pump system.
For tanks under 1,000L, DIY installation is often achievable over a weekend. However, we recommend professional installation for larger household water tanks or complex setups to ensure optimal performance and compliance with local regulations.
Our team can provide detailed installation guides and advice or connect you with our network of trusted installers throughout New Zealand.
What should I consider when choosing the placement for residential water storage tanks?
Correctly positioning a water tank for house use is crucial for optimal performance and longevity.
We recommend choosing a location that maximises natural rainwater collection from your roof while keeping the tank accessible for maintenance. Consider existing drainage patterns, potential overflow paths, and local council setback 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.
