Kiwi sections are getting smaller, and the tank has to fit the section it is given. The Promax Slimline is built for that: narrow enough to sit along a fence or behind the house, with seismic restraints already built in. This article is written for homeowners weighing one up for their own property. If you are a builder, drainlayer or plumber specifying tanks for clients, the trade view of the Slimline covers the install detail instead.
Kiwi sections are getting smaller
New section sizes in Auckland, by far our biggest urban centre, have reduced by a third in the past three decades. New build sections now have a median size of less than 500 square metres, with the average section about 120 square metres smaller than in the rest of New Zealand. Other towns and cities tell a similar story.
Houses on new developments are built close together on relatively small blocks, while many quarter-acre sections are now subdivided into diminutive parcels of land. The practical effect is that outdoor space has become the scarcest thing on a property. A tank that needs open ground around it is competing with the lawn, the deck and the driveway, and on most new sections it loses.
Designed for a smaller Kiwi section
New Zealand's housing trends reflect smaller section sizes, especially in metropolitan areas like Auckland, Wellington and Christchurch. The Promax Slimline Tank is built to fit into those smaller residential spaces rather than dominate them.
That is a different design problem from simply making a tank smaller. Shrinking capacity to fit a section costs you water. The Slimline instead changes the shape of the footprint, taking a strip along a wall or a boundary rather than a circle of open ground. It fits into smaller residential spaces with an unobtrusive style that makes it look right at home. You can see the current range in Promax Slimline water tanks.
Unobtrusive by design
With a design this slender and compact, the Slimline becomes an invisible ally. Positioned discreetly behind your house or along the fence, its unimposing silhouette ensures it will not invade your space or cast unsightly shadows.
Shadow matters more than people expect on a small section. A tall, wide tank near a boundary can take the sun off a strip of garden or a window for part of the day, and on a compact property that is a real loss rather than a detail. A narrow profile keeps the tank out of the way of both the space and the light. For homeowners who prioritise how their property looks, the Promax Slimline Tank is a clear winner.
Seismic restraints are built in
Installing the Promax Slimline Tank is not only hassle-free but also cost-effective. Unlike competitors, our Slimline tanks come with in-built seismic restraints, which eliminates the need for additional posts. Safety compliance is not traded away against installation cost.
For a homeowner this shows up as a shorter, simpler job on site and fewer trades and materials in the quote. It also removes a decision you should not have to make: the restraint is not an optional extra you might skip to save money, because it is already part of the tank. If you are not sure what a restraint does or why it is required, we explain it in what is a seismic restraint.
Compact and compliant
While primary structural elements are generally well designed and detailed by a structural engineer, non-structural elements such as water tanks can often be overlooked through the various stages of a project. Good seismic design elements save lives and costs.
The in-built seismic restraints mean that safety requirements are not compromised with a Promax Slimline Tank. Promax also offers a free PSI to confirm the seismic restraints are built in accordance with New Zealand Building Code (NZBC) requirements. If your tank is going into a new build rather than an existing home, the compliance and space planning side is covered in slimline water tanks for new builds.
More water than the footprint suggests
Do not be misled by its size. A Promax Slimline Tank may be compact, but it consistently delivers a surprising amount of water. Users, whether opting for the Slimline or other models in our range, attest to the efficiency of these tanks, especially during water restrictions.
That is when stored water stops being a nice idea and starts being the difference between a garden that survives the summer and one that does not. A tank's capacity serves as a guide to potential storage, offering continuous access to a valuable water supply. If you want the background on why restrictions happen and how storage helps, we cover it in water restrictions: causes, impacts and solutions.
Affordable to buy, cheaper to live with
The Promax Slimline Tank caters not only to smaller sections but also to smaller budgets. It is an affordable solution for water storage, and it enables compliance with stormwater regulations without breaking the bank.
The cost story does not stop at purchase. By reducing reliance on mains water supply, the tank saves you money over time as well as aligning with sustainability goals. Affordable, easy to install and capable of storing ample water, it fits the ethos of sustainability that many of our customers, and we as a company, value. For a household, that combination is unusual: the sustainable option and the cheap option are the same option.
The right fit for your home, lifestyle and budget
The case for the Slimline is not one big advantage. It is that a small section, a tight budget, a wish to keep the property looking good and an interest in using less mains water all point at the same tank, and the seismic restraints come with it rather than as an extra line on the quote.
