The logistical, environmental, and financial repercussions of increasingly extreme weather patterns can cause a cascade of unforeseen problems for your home or farm. Good thing rainwater harvesting has become a reliable way to ensure peace of mind while making the most of a free resource.

When you incorporate a rainwater harvesting system on your farm or property, it reduces your reliance on scheme water and results in an array of benefits.

Here are 6 reasons to harvest rainwater and their benefits:


1. Saves money

Rainwater doesn’t cost a thing. Leveraging this free resource enables you to cut costs in multitudes of ways.

So, how much money can you save by adapting a rainwater harvesting system? 

When you plumb rainwater from your water tank into your home, you can save up to 20% of average of your household water use.

Did you know that rainwater harvesting in Australia enables you to collect about 80% of the rain that falls on your roof? An average 8 x 12-meter roof can provide approximately 600 gallons (or 2,700+ litres) of water in an hour with moderate rainfall. That's enough water to fill 15 bathtubs.

Not to mention that rainwater harvesting gives you more water to use for laundry, irrigation, flushing, showering, and drinking.

2. Has health benefits

Rainwater contains fewer salts, such as calcium and magnesium, because it doesn't run through sedimentary rocks in the earth like groundwater does. It doesn't contain chemicals like chlorine and fluoride, which is the case with mains water, so your plants and animals will love it.

And since municipal water supplies can be prone to contamination and may contain trace amounts of discarded prescription drugs, using fresh rainwater as much as possible ensures your own peace of mind.

Fresh rainwater is great for domestic uses: e.g. washing cars, windows, hair, and even dogs!

3. Rainwater is soft

Rainwater is considered soft water. In line with the benefits outlined in the previous item, rainwater does not contain a lot of dissolved minerals, unlike hard water. This makes washing for domestic purposes easier as soft water helps soaps and detergents work better.

When properly maintained, your rainwater tank can be used for drinking and cooking purposes – even bathing.

4. Fends off negative environmental impact

Reduces stormwater runoff

Water storage through rainwater collection has a positive impact on the environment. In fact, it helps control storm-water runoff, which protects your land from erosion and reduces the threat of local flooding. 


Reduces demand for groundwater

Another way rainwater tanks protect the environment is by reducing the demand for groundwater.

Groundwater is available in limited quantities, it’s only right that we all act to conserve it.

Reduces energy consumption

Harvesting rainwater also reduces the energy consumption by municipal water systems, which takes a lot of energy to run, what with the turbines and pumps needed for collection, storage, and delivery.

Collecting your own rainwater enables you to reduce energy consumption while reducing the amount you pay on water bills.


5. Has logistical benefits

Strategically placed rainwater storage tanks help keep your farm schedules running smoothly under challenging environmental conditions.

By harvesting potentially damaging high-volume runoff from storms, you'll later be able to distribute this water in a controlled fashion to areas around your farm or property that need it the most.

When traditional dams, creeks, and soaks run dry due to drought or are contaminated with algal blooms, the water in them won’t be of much help. Rainwater harvesting, in other words, gives you a sense of security.

6. Expands your options

Installing a rainwater tank frees you from being stuck with just having one water source on your farm or property. It reduces your reliance on scheme water which allows you to put water on aspects around your farm that need it most.

And in cases of emergency, which is something you cannot predict, you will have a safe backup of water for whatever purpose you need it to serve.

Why Choose Poly Rainwater Tanks for Rain Catchment?

Poly rainwater tanks have a slew of benefits. To name a few, they are:

  1. Easier to clean and maintain than other types of water tanks.
  2. Prevents algae (with the right poly water tank that’s thick enough to prevent light in, you’ll never have to worry about algae contamination).
  3. 100% rust and corrosion-free.
  4. Does not leach any harmful chemicals.
  5. Strong and reliable yet lightweight, making them easier than all other types of rainwater tanks to transport and install.

Even on the smaller scale of your own farm or residence, the benefits made possible by rainwater harvesting is seen not only in the decrease of your water bills, but also in the time, effort, energy, and money that would otherwise be used on repair and recovery of the probable negative impacts of not having a rainwater collection system in place.
