Types of retention tanks

Retention tanks come in a variety of shapes, sizes, and materials to suit different properties and needs. Here’s a quick guide to some popular options:

Underground tanks

Perfect for saving garden space, underground retention tanks are installed below ground, keeping them out of sight while efficiently storing rainwater.

Round tanks

Round retention tanks are great for storing large amounts of water, often made from durable materials like corrugated steel. However, they do require more space.

Slimline tanks

Ideal for smaller spaces, slimline tanks fit neatly along the side of your property, offering a compact solution for water storage.

Square tanks

Square tanks provide more capacity than slimline options without taking up as much space as round tanks. You can even place two side by side for additional storage.

Industrial tanks

Designed for maximum capacity, industrial tanks are made with thicker, more durable materials and often include advanced filtration systems. They can be installed underground or as low-profile solutions for larger properties or commercial use.

The benefits of high-quality retention tanks

A retention tank does more than just store rainwater to help prevent flooding - it’s a smart way to save money and reduce reliance on mains water. The best tanks come with built-in filters and systems, giving you access to clean, usable water for tasks like watering your garden. Made from high-quality materials, they’re designed to prevent leaks and resist corrosion, ensuring long-lasting performance. With a retention tank, you can store water safely and enjoy lower utility bills while doing your part for the environment.

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

Choosing the right retention tank depends on your needs and space. Underground tanks are great for saving yard space but require professional installation. Above-ground tanks are easier to install, but you’ll need to think about the size, shape, and location to make sure they fit your property. The materials, piping, and filters also play a big role in how you can use the water - some tanks can connect to your plumbing for tasks like flushing toilets, while others are perfect for garden watering and basic storage.

What’s the difference between a retention tank and a detention tank?

Retention tanks and detention tanks may sound similar, but they serve different purposes. A retention tank stores rainwater for long-term use, like watering your garden or even connecting to your plumbing for tasks such as flushing toilets, making it a great choice for water conservation. On the other hand, a detention tank is designed to manage stormwater by temporarily holding it and then slowly releasing it into the drainage system, helping prevent flooding. While retention tanks provide a backup water supply, detention tanks focus on controlling water flow during heavy rains. Both are valuable solutions, but the right choice depends on your property’s needs.
