The effects of climate change such as unpredictable rainfall and prolonged droughts are evident all over the world. In September, Reuters published an article predicting that Australia would experience a widespread water crisis before the end of 2020 unless the rain patterns change. Evidence of this is clear with several parts of New South Wales and Queensland experiencing drought conditions since 2016.

With limited and unpredictable rainfall, now is the best time to invest in rainwater harvesting systems. Installing an underground rain water storage tank is essential to securing your water supply. It can help to support your family’s water demand in the rainy and dry seasons. In this article, we focus on some of the benefits of an underground water storage tank.

Underground Water Tanks


Underground Water Tanks Saves Space

An underground concrete water tank only takes up space during construction. Once installed, it is out of sight. This allows you to repurpose the space for lightweight features such as an outdoor dining area.

An underground water tank is a great option if you have limited space around your house. For extra water storage, you can build a deeper tank without compromising structural integrity. Sydney Water Tanks offer superior engineering solutions and advice. We can guide you on the type and size of tanks that would be best suited for your application.


Underground Water Tanks Saves Water

By collecting rainwater efficiently, you can conserve the conventional municipal water resources. Stored rainwater can be used directly for flushing toilets, washing clothes and other cleaning activities. You can even use the rainwater to top up your swimming pool. This reduces your demand for water supplied by the city and makes more available for other users.

Underground rainwater storage tanks are quite easy to fill. It is estimated that one milimetre of rainfall spread over a square metre of roofing is equivalent to one litre of water in your tank. The Australian Bureau of Meteorology (BoM) reported that 2018 was the 39TH driest year in their recorded history. Yet, the average rainfall received across the country was about 412.8 mm. As such, a 100 m2 house would have harvested more than 40,000 litres of rainwater in 2018.


Underground Water Tanks Saves Money

Harvesting rainwater can significantly cut down your water bills. This is because rainwater can replace more than half of your household water demands.

Underground water tanks fill up passively. The rainwater harvesting system directs water to your tanks under the force of gravity. This saves you the time and resources necessary to run a pump when filling the tank.

Also, underground tanks are built to last. They are safe from extreme weather conditions, UV deterioration and vandalism. They also have low maintenance requirements. Their minimal operation costs mean that you can recover your investment quickly.

Access to an affordable water supply empowers you to invest in various projects that can save you more money. These include growing vegetables and farming fish, poultry or cattle for personal or commercial use.

Underground water tanks have several other benefits including environmental conservation and increasing the value of your home.
