Retention Tank Supply & Installation

Plumbspec provides reliable retention tank supply and installation across Wellington, helping homeowners manage stormwater, store rainwater and stay prepared for emergencies.

Rain Water Storage and Stormwater Solutions in Wellington

Managing heavy rain and runoff is a big part of protecting Wellington homes, especially with the wild weather we experience each year. That’s why Plumbspec supplies and installs high-quality retention tanks designed to control excess water before it becomes a problem. A well-planned stormwater retention tank helps reduce flooding, limits erosion around your property and supports better overall water management. Many homeowners also choose a rainwater harvesting tank or other forms of retention tank to make the most of Wellington’s frequent rain, using collected water for gardens, outdoor cleaning and general conservation. With the right setup, your retention and stormwater retention tanks work together to keep your property safe, efficient and environmentally responsible.

Being prepared for emergencies is just as important as managing day-to-day stormwater. A dedicated rainwater harvesting tank gives you a dependable backup supply when normal water services are disrupted. Your retention tanks store clean rainwater from your roof, offering peace of mind during earthquakes, storms or major outages. Many Wellington households now see a stormwater retention tank as essential – not only for protecting their home, but for ensuring they have water available when it matters most. With Plumbspec’s expert retention tank installation services, your system is ready for both everyday use and unexpected events.

Our Recommended Retention Tanks

Choosing the best retention tank or water tank for your property can be challenging but the Plumbspec team works with clients to assess the site and find the perfect water tank for your needs.

A simple stand-alone water tank such as The Tank Guy is an economical option with sizes ranging from 600L to 4000L. The most common size we install is the 800L Slimline tank as pictured, with prices starting from around $700 plus delivery and installation.

If you are looking for a modern retention tank design, we recommend the corrugated iron look from Tanksalot. These are a slim but sturdy design that don’t require a lot of bracing and come in a range of colours and sizes. Prices start from $1600 plus delivery and installation, for a 650L tank as pictured.

The Thin Tank is a versatile option coming in many different colours and sizes, while being slim enough to fit into almost any space discreetly. A common size we install is the 500L water tank with brackets, and prices start from $1900 plus delivery and installation.

Property Size

Retention water tanks come in a large range of sizes from 200L up to 5000L or more, so consider how many people the retention tank will need to service in your household or business.

Location & Site

You will need a level piece of ground to install a retention tank, which is sometimes hard on Wellington’s terrain! That’s why Plumbspec can offer a wide variety of water tank shapes to fit your site and we offer full site preparation and installation to make it easy for our clients.

Aesthetics

It is important your rainwater retention tank looks good once installed, so Plumbspec offers a wide range of modern and neutral colours to blend in with your home or fence colour. Rainwater tanks are available in uv-stabilised polyethylene or corrugated steel, and can even be fitted with planter boxes.
