Retention Tanks
- Retention tanks are multipurpose tanks that collect rain and stormwater runoff, preventing flooding in your area when the drains are overwhelmed. They also store that water for later use which means you won’t need to draw as much from the mains supply, saving you money at the same time too.

Types of retention tanks
Retention tanks come in different shapes, sizes and materials to fit your property and requirements. Some of the most common types of tanks include:
Underground tanks
To not detract from garden space, many people in New Zealand choose an underground rainwater retention tank. A space is dug for the tanks and pipes below your property.
Round tanks
Round retention tanks often have the largest capacity but also take up quite a lot of space. They’re usually made of durable metals, such as corrugated steel.
Slimline tanks
For a smaller option that can be kept at the side of your property, you can choose a slimline water retention tank.
Square tanks
Square tanks have a larger capacity than slimline ones without having a large footprint, like round tanks. You can also sit two side by side.
Industrial tanks
Industrial tanks have the largest capacity. They’re made out of durable materials with increased wall thickness, can fit underground or be low profile and they include advanced filtration systems.
The advantages of high-quality retention tanks
A retention tank is more than just rainwater storage to prevent floods in New Zealand. The best quality ones also include filters and systems to give you access to that water for use instead of drawing from the mains. That means less strain on the system and lower utility bills. High-quality tanks are made from superior-grade materials, preventing leaks and corrosion. That means you’ll be able to store water for longer. The filtration will allow you to use the water safely for watering your garden.
How to choose a retention tank that’s right for you
Your requirements will dictate which retention tank is best for you. Underground options don’t take up space but do require some upheaval for installation. If you choose an above-ground option, you’ll need to consider the size, location and shape to fit the space you have available.
Finally, the materials, piping and filters will be crucial to what you can do with the water. Some can redirect to your plumbing system for flushing toilets, whereas others are suited to more simple storage for watering your garden.
