Water Detention Tanks

Featuring the best detention tanks in New Zealand

Detention tanks are becoming increasingly popular in New Zealand as homeowners look for ways to manage storm and wastewater on their properties. You can find detention tanks in all shapes and sizes, which means finding one to fit your property won’t be an issue. They are an important part of a wider range of high-quality rainwater storage solutions that you can find on ArchiPro.

Types of detention tanks

Tanks for storing stormwater come in various sizes and use different materials. Some of the most popular options in New Zealand include:

Slimline tanks

A slimline stormwater detention tank is a popular option for properties in New Zealand that have limited space or want the tank hidden from view.

Round tanks

A round water detention tank is usually made from corrugated steel. They’re strong, durable and can hold large amounts of water, often up to 25,000 litres.

Square tanks

Square tanks have a smaller footprint than other detention tanks. They’re a good choice if you want to store a lot of water in a tight space or install multiple tanks side by side.

Underground tanks

For a tank that’s out of sight, you can install an underground storm vault. These tanks are usually lightweight, made of polyethylene, and need to be installed professionally under your property.

The advantages of high-quality detention tanks

The best detention tanks are built to handle heavy rainfall in New Zealand. They’re large enough capacity to handle most of the storm runoff and their piping and drainage systems are simple but efficient. They seamlessly connect with existing drains for surface runoff and release their contents into the appropriate waterways. Crucially, a high-quality detention tank will be made of a robust material to prevent leaks. The best products will have anticorrosion properties that last for years, giving you a stormwater tank that you can rely on.

How to choose a detention tank that’s right for you

There is a number of factors that will help you choose the right detention tank. First, you’ll need to think about the space you have available for the tank. If you have a large property then this won’t be so much of an issue. The only consideration is where to put it and how it’ll fit in its surroundings. If you are limited on space then you might be tempted by an underground system which doesn’t take any yard space at all. You’ll also need to consider what size tank you need depending on the amount of water you want or need to store. Smaller models like slimline tanks hold around 6,000 - 10,000 litres while larger options can hold upwards of 25,000 litres.
