What Are Our Most Popular Products?

Water Tanks

When you sell such a wide variety of products like we do at Rotational Plastics, naturally the question comes up. What is the most popular product in our range? We had a look at our statistics to see the answer.

It turns out that tanks are the most popular category of product on our website. People love our plastic tanks, whether for retention, storage or even spray water tanks. But why are tanks so popular?

Many people are looking to move off the grid, and water is one of the main utilities which you don’t have control over unless you collect your own. With a water tank, you can collect and store your own water. This is also an excellent option in more rural areas where mains water supply is not available.

What does our range of tanks include?

Above ground tanks – Above ground tanks are increasingly common across New Zealand because they are a cost effective way to collect and store water. The advantage of these tanks are that installation and maintenance is both cheap and easy, since the tank is easy to place and get to. There is no excavation needed. When maintenance is needed, which involves emptying and cleaning the inside, this is much easier with an above ground tank – simply hose down the inside and tilt the tank to drain the water.

Below ground/underground tanks – These tanks are installed either partially or completely under the soil, and are another popular option. However, they are a more permanent solution, as they require excavation to install them. The benefit is that they don’t take up any space above ground, so you still have a backyard to enjoy. They are most often installed during the building process of the home, minimising installation costs and inconvenience once the home is built. Underground tanks need to be reinforced in order to handle a long life underground.

Mobile home water tanks – These are the perfect solution if you need to storage water in your mobile home. Also good for boats, these plastic tanks won’t corrode and will ensure that your water stays clean and protected. These come in a range of shapes and sizes to suit a wide range of applications.

Spray water tanks – These are tanks with pressure washing systems. They come in a range of sizes and shapes and can be used for many applications.

All About Detention tanks

Harvest Rain Water, Water Tanks

You maybe have been browsing our website and no doubt came across our detention tank range. There are tanks in all shapes and sizes. But what are these tanks actually for?

Detention tanks, which are sometimes called retention tanks (though this is incorrect), are generally used when storm water system in not adequate enough to deal with the job of extracting water. The detention tanks works to slow down the rain that comes off your roofs and goes into the stormwater system, to prevent overflowing. This is generally an issue in older areas where a lot of new houses are being built and a lot of strain is being put on the stormwater system. Where this is an issue, councils often require the use of detention tanks.

What happens if you have a retention tank is instead of the water flow straight into the stormwater, it comes off the roof and other areas and into the detention tank, then drains slowing through the orifice outlet into the stormwater system. The tank and orifice will be specified to drain at a certain rate, depending on what the stormwater can handle. This can take hours depending on the flow rate. The area your building is in will have specific requirements for this.

Detention tanks can be stand alone units, but often times there are combined with a retention tank. The retention tank stores water for when you need it, in contrast to the detention tank. So how this works will be if you use a 3000 litre tank, the bottom 2000 litres will be used to store your water, and the top 1000 litres for detention.

So what do you need to look for when buying a detention tank? The first thing you’ll need to look at are the council requirements in your area for water flow. You need a tank that will meet these requirements, which will determine the size your orifice you need to select. If you are going to going to be getting a combination retention tank, then you also need to take into account how much water you need for storage. You also have the choice of above ground or below ground.

We have a wide range of detention tanks on our website in all kinds of configurations, sizes and shapes. Have a look through our range and contact us if you need assistance selecting a tank for your home!
