Water tanks are an important investment for homeowners, businesses, and farms alike. They allow you to store rainwater, graywater, or other types of water for future use. But when it comes to choosing between above-ground and underground water tanks, which option is best?

Pros and Cons of Above-Ground vs. Underground Water Tanks

Above-ground water tanks are the more common choice for many people, as they are easier to install, access, and maintain. They come in various sizes, shapes, and colors, making them a versatile option for residential, commercial, and industrial applications. Additionally, above-ground water tanks are typically less expensive than underground ones, as they require less excavation and construction work.

On the other hand, underground water tanks are a more discreet option that can save space and enhance the aesthetic appeal of your property. They are well-suited for areas where space is limited, such as urban or suburban environments. Furthermore, underground water tanks can prevent algae growth and maintain water temperature, as they are shielded from sunlight and extreme weather conditions. However, underground water tanks require more preparation, installation, and maintenance work, as they involve excavation, backfilling, and ventilation.

Choosing the Right Water Tank for Your Needs: Above-Ground vs. Underground Options

When deciding between above-ground and underground water tanks, consider the following factors:

• Water Usage: How much water do you need to store, and for what purposes? If you need a large volume of water for irrigation, firefighting, or other applications, an above-ground tank might be a better fit. If you need smaller amounts of water for household use, such as flushing toilets or doing laundry, an underground tank might be more appropriate.

• Available Space: How much space do you have on your property, and where is it located? If you have ample space and want your tank to be visible, an above-ground tank could be ideal. If you have limited space or want your tank to be hidden, an underground tank could be the way to go.

• Budget: How much are you willing to spend on your water tank, including installation and maintenance costs? If you have a tight budget, an above-ground tank could be a cost-effective option. If you have a higher budget and want a long-lasting, low-maintenance tank, an underground tank could be a worthwhile investment.

Above-Ground vs. Underground Water Tanks: Which One Is More Cost-Effective?

When comparing the cost of above-ground and underground water tanks, it’s important to consider the initial installation costs, ongoing maintenance costs, and potential repair costs. While above-ground tanks are typically less expensive to install, underground tanks can save money in the long run by reducing water loss due to evaporation, algae growth, and other factors. Additionally, underground tanks can improve the overall value of your property and potentially lower your water bills, as they provide a sustainable and reliable source of water.

Environmental Factors to Consider When Choosing Between Above-Ground and Underground Water Tanks

When choosing between above-ground and underground water tanks, it’s important to consider the environmental factors that could impact your decision. For example, above-ground water tanks are more susceptible to weather damage, such as high winds or hail, while underground tanks are less likely to be affected by such conditions. Additionally, above-ground tanks can be more prone to algae growth and water contamination due to exposure to sunlight, while underground tanks are shielded from such factors.

How to Decide Between Above-Ground and Underground Water Tanks for Rainwater Harvesting

Rainwater harvesting is a sustainable and eco-friendly practice that can provide a reliable source of water for various applications. When deciding between above-ground and underground water tanks for rainwater harvesting, consider the following factors:

• Rainfall Patterns: How much rain do you receive in your area, and how often? If you live in an area with frequent and heavy rainfall, an above-ground tank could be a good choice. If you live in an area with limited rainfall or drought conditions, an underground tank could be more effective.

• Water Quality: What is the quality of the rainwater in your area, and what factors could affect it? If your rainwater is likely to contain contaminants or pollutants, an underground tank could be a better choice, as it can provide additional protection against such factors.

• Available Space: How much space do you have on your property, and where is it located? If you have ample space and want your tank to be visible, an above-ground tank could be ideal. If you have limited space or want your tank to be hidden, an underground tank could be the way to go.

Auckland is a beautiful city with much to offer, but it’s no secret that it can rain quite a bit here. Unfortunately, Auckland’s public system is not equipped to handle extreme weather events, so it’s up to property owners to do their part and help prevent flooding and water damage. One way to do this is by retaining rainwater on your own property. Here’s what you need to know.

The Importance of Water Retention in Auckland: Why It Matters More Than Ever

When it comes to managing rainwater, every drop counts. Retaining water on your own property can help reduce the risk of flooding and erosion and provide a valuable source of water for plants and gardens. Additionally, with the extreme weather events in Auckland, it’s clear that the public system alone cannot handle the demand for water management. This is why water retention is more important than ever.

Auckland’s Public System vs Extreme Weather: Why Retaining Water is Critical

Auckland’s public system was not designed to handle the amount of rain that we see today. When there is too much water flowing into the system, it can cause overflows, sewage spills, and other issues. Retaining water on your property can help alleviate some of the stress on the public system by reducing the amount of water needed to be processed. It’s a win-win situation: you help protect your property, while also helping to prevent damage to the larger community.

How to Prepare for More Rain: Tips for Water Retention on Your Property

So, what can you do to retain rainwater on your own property? There are many simple and effective ways to get started, such as installing detention tanks and retention tanks. Retention tanks are a great option for collecting water from your roof for later use such as in your garden. Detention tanks store the water temporarily to slowly release it back into the stormwater system.

Saving Water and Money: The Benefits of Retaining Water on Your Property

Not only does retaining water on your own property help protect against flooding and water damage, but it can also help you save money on your water bill. Using rainwater to water your plants and garden can reduce your reliance on the public water supply. Plus, many of the water retention solutions mentioned above are affordable and easy to install, making them an accessible option for many homeowners.

The Environmental Impact of Water Retention: Why Every Property Owner Can Make a Difference

Finally, it’s important to note the positive environmental impact of water retention. By reducing the amount of water that runs off your property, you help prevent erosion and pollution in nearby bodies of water. Additionally, retaining water can help promote biodiversity and create a habitat for wildlife. Every property owner can make a difference by taking steps to retain rainwater.

Auckland Council’s Water Management Plan: What You Need to Know and How You Can Help

The Auckland Council has a water management plan in place to help address the challenges of water management in the city. As a property owner, it’s important to be aware of this plan and how you can help. The council offers resources and information on rainwater harvesting, green infrastructure, and other strategies for water retention. Additionally, they offer rebates and incentives for property owners who take steps to retain rainwater. By working together with the council, we can create a more sustainable and resilient Auckland.

The Future of Water Retention in Auckland: How We Can Work Together to Protect Our City

In the face of increasing rainfall and the limitations of the public water management system, it’s clear that we all have a role to play in protecting our city. By retaining rainwater on our own properties, we can help alleviate the strain on the public system, reduce the risk of flooding and water damage, and create a more sustainable environment. Whether you’re a homeowner, business owner, or community member, there are steps you can take to help. By working together, we can build a brighter future for Auckland.

Water storage tanks are essential in households today because they ensure that homeowners have enough water supply for their daily needs, like washing food, cleaning the dishes, and laundry. They also make a great addition to homes because they promote water conservation and rainwater collection.

However, it’s no secret that finding a suitable water tank can be a bit tricky because of the different options available. Moreover, they come with varying pros and cons. If you plan on buying one for your home, we suggest going through our quick water tank shopping guide and product comparison below.  

Above-ground tank vs. Below-ground tank

When shopping for water tanks, homeowners mostly choose between the above-ground or below-ground type. As their names suggest, their key difference lies in where you can install them.

Below Ground Tank

If you want to have a water storage tank but want to conceal it and save space in your property, then you might likely prefer the below-ground or in-ground type. It also makes a good choice for people who want to protect their tanks from harsh weather elements, vandalism, and premature damage.

However, you might have to contend with a few disadvantages if you opt for an in-ground tank. Some examples of these cons include:

• Difficulty seeing cracks, leakages, or other signs of damages
• High installation cost because of added excavation costs
• High operational price because you need to install a pumping system

Above Ground Tank

If you are eyeing a practical and affordable water storage option, the above-ground type might suit you. Because it’s far simpler to set up than the latter option, as an above-ground water tank doesn’t come with the expensive installation cost. Moreover, you can move the water tank wherever and whenever you want – a perfect compromise if you don’t plan on staying in a property for a long time.

However, just like the other type of water storage tank, the above-ground option also comes with a few disadvantages, including:

• Increased vulnerability to damages (vandalisms, accidents, etc.)
• Poor insulation, causing the water temperature to fluctuate depending on the season
• It can be costly to run if you want to keep the water temperature consistent

Additional Water Tank Shopping Tips

When choosing between an above-ground or below-ground water tank, we highly recommend considering the things we shared above. Additionally, it would help if you also looked into other factors like:

• The type of material used: Water storage tanks are made from varying materials, including plastic, metal, and fiberglass. In most cases, it’s better to opt for plastic because they require very little maintenance. They are also lightweight, affordable, and non-corrosive.
• The location where you intend to install the tank: The size of the area plus other factors such as sun exposure, road access, and whatnot also plays a crucial role when planning what type of water tank to buy.

Detention vs. Retention Tanks

Besides the two options we shared above, you might also be interested in buying a detention or retention tank. Essentially, you can find both tanks underground. They also collect stormwater, but for different reasons: the detention tank manages drainage water while the retention tank collects rainwater. Here are other insights that might come in handy when choosing between the two:

• Retention tanks make an excellent addition to your home if you live in areas with little to no access to reticulated water sources.
• A detention tank is a must-have for homes that need to boost their drainage efficiency during the rainy season. However, we recommend opting for detention tanks equipped with a dual filtration system to prevent debris from getting stuck.
• Choose a tank based on the materials. While you might find ones made from steel or fiberglass, the ones made from polyethylene are the best option because of their durable make, high water capacity, and non-corrosiveness.

We get asked this question quite often: what is the difference between a retention tank and a detention tank?

Both tanks are used to collect rainwater or stormwater. However, a retention tank is designed to keep the water for use at a later date, while a detention tank eventually drains the water shortly after it is collected.

Rainwater vs. Stormwater

For the purpose of clarity, it is worth distinguishing between rainwater and stormwater.

Rainwater quite simply refers to the rain that falls on the roof, which is often harvested into a storage tank before it gets in contact with the ground. On the other hand, stormwater refers to rainwater falling on roofs down to the gutters and downpipes or runoff from ground surface areas such as driveways, gardens, lawns, footpaths and roads. Naturally, rainwater is of much higher quality since it contains fewer contaminants (e.g. soil, debris, chemical fertilisers, oil residues, etc.).

Harvesting rainwater can help reduce your water bills, as you are essentially utilising a free, renewable resource. A water retention tank would be a good investment for this particular purpose.

Water Retention Tanks

A typical retention tank is designed to harvest both rainwater and/or stormwater, and retain the water rather than simply draining it off. The harvested rainwater can then be used for many purposes such as:

• irrigating your garden
• flushing toilets
• topping up your swimming pool without using mains water
• washing your cars and driveway
• washing clothes
• drinking (if the water system is properly maintained and water is treated)

Stormwater is generally unsafe for drinking, but it can often be utilised for low-risk purposes such as toilet flushing and garden watering. If treated, stormwater can even be used for filling swimming pools.

Investing in retention tanks makes sense, even more so if you’re in a rural area where there is no access to reticulated water supply or where there is a greater need for water for agricultural use.

Stormwater Detention Tanks

Detention tanks also collect rainwater and/or stormwater, but they are typically utilised as part of an effective stormwater system for new homes. Local councils require new homes to have an effective drainage system, which would help in managing the flow of runoff entering bodies of water.

As the name suggests, a water detention tank is designed to “detain” water, that is, to say, it holds the water for a limited period only. The tank is intended to drain the water and remain empty except during a rainfall event and for a short period thereafter.

Stormwater detention tanks have a large inlet pipe and a smaller outlet, which prevent sudden surges of runoff by averaging the out peak flow. This takes some pressure off our ageing stormwater network and consequently prevents flooding.

Why should you use a detention tank?

Its biggest help is assisting your local area’s stormwater drainage facilities to drain manageable loads of water runoff during heavy downpours. Increasing the capacity of existing drainage facilities to keep up with increased stormwater flows has its constraints (i.e. cost and space), which is why many councils have passed on to new home owners some of the responsibility for their stormwater runoff.

To put simply, whether you need a stormwater detention tank and to what extent you need it depends on your local council. How big the detention tank basically depends upon a number of things, such as the size of your property, the building structures within your property, and the surface area of your roof. Your local builder should be able to tell you the right size you need, and your local council should have some table or equation for this as well.

A detention tank can be a standalone facility, or it can be made to work double as a retention/detention system. It can also be used in addition to a rainwater tank which, in heavy downpours, will fill up quickly. The addition of a retention tank, in this case, keeps space available for more water to be detained in the event of prolonged or consecutive rainfall. This solution is preferable as it maximises your rainwater/stormwater collection. This type of system may need to be designed for your property and submitted for council approval.

Because stormwater often carries small debris, blockage often occurs which makes the detention tank ineffective. We at Rotational Plastics have designed our detention tanks with a double-filter system, which features one filter at the inlet point to arrest large debris and another filter by the tank outlet to catch smaller particles.

Materials used for water tanks

Rainwater/stormwater tanks come in different sizes, shapes and materials. Below are some of the most commonly used materials for retention and detention tanks.

• Galvanised steel. Steel water tanks have a zinc coating that protects it from corrosion. They are built with capacities from about 30,000 litres to a million litres, making them a suitable solution for large storage requirements. Over time, the zinc coating may leak into the water which results in rusting. This problem is often overcome by adding liners made of food-grade polyethylene, although it is expensive to fabricate and is vulnerable to wear over time.
• Fiberglass. The quality of fibreglass tanks depend on the maker. In general, they are rigid but light and thin, making them prone to cracking. This type of material needs a food-grade coating to make it safe for storing potable water.
• Polyethylene. The most popular water tank material by far, polyethylene is exceptionally strong and durable but relatively lightweight. These properties make polyethylene water tanks easy to install and cost effective. Polyethylene is a high-quality plastic that is recyclable and reusable, making it an environment-friendly material. It is a food-grade plastic so it’s non-corrosive and does not need a liner, which tends to disintegrate over time. The flexibility of plastic allows the tank to be moulded into various shapes and dimensions. Poly tanks can be made in storage capacities of up to about 50,000 litres.

If you are building a new home, there may be several requirements that you’ll need to meet. One of these requirements might be stormwater management, which will require the use of a detention tank. If you are experiencing flooding, a detention tank may also be your answer.

What are detention tanks?
Detention tanks are large tanks that are normally installed below the surface and used to suppress the effects of heavy rainfall, or stormwater. They work by temporarily storing the rainwater runoff during rainfall and slowly release the water through a small diameter orifice into the public storm water system. This reduces the peak flows of stormwater and reduced the chance of flooding due to an overloaded stormwater system.

Detention tanks are usually required in areas where storm water flooding risks are high. This is especially true in many areas in Auckland, with the current increase in population and housing. Generally speaking, if you are adding roof space by extending or building a new home in areas where stormwater systems have not been renewed, you will most likely require a detention tank.

Detention tanks can also be useful for managing stormwater onsite. This is most common used in combination with soak holes. This systems gives the ground enough time to soak excess water which prevents any surface or ground related flooding.

How big does my detention tank need to be?
In Auckland, a rule is based on several conditions such as the “storm of the 100 years” principle, which would be to allow for 100 liters per 1 square metre of roof surface area. Depending on detention requirement, the outlet orifice can range between 10mm-40mm. Some further information can be found regarding size of detention tank from Auckland Council here.

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.
