Why Bother With Rainwater Harvesting?


Water is easy to access. Just turn the tap or shower on and out comes water. Look around your neighbourhood and you could probably see fire hydrants, public taps, and other public utilities that require water to function. Look around in your home long enough and you’ll find last month’s water bill.

So why bother with rainwater harvesting? Below are the tasks and chores that rainwater can be used for, as well as other advantages you need to know about.


This is one of the first uses of collected rainwater. After all, rain falls on plants and helps them grow, and this is not only because rain is water—rain contains substances plants need and is capable of stimulating plant growth as well as soil chemistry (to make it conducive to plant growth).

Driveway Cleaning

The driveway can be a large area of your property, and if mains water is used to clean it, you can end up paying so much for water in just one month. Use even untreated rainwater, and you can expect a significant amount of savings in your water bill each month.

Vehicle Washing

Considering that rainwater that’s sufficiently filtered and treated will not leave stains on vehicle paint, they’re the perfect substitute for mains water in this regard.

Clothes Washing

Rainwater that’s treated and filtered even further can be made suitable for clothes washing. Considering that clothes washing accounts for a significant per cent of water use each year, using rainwater as a substitute to mains water in this task, therefore, allows you to save so much money, which you, in turn, can use for other essentials.

Dish Washing

Since dishes are used in each meal, and they need to be washed for them to be suitable for use, it follows that the task of washing dishes requires a lot of water in a month. If mains water is used for this task, then a household can end up paying much per month on the water bill.


It’s hard to believe, but rainwater can actually be treated and filtered to the point that it can become suitable for consumption. Rainwater often used for consumption in place of mains water can also help a family save on finances for their monthly water bills.

Other Advantages of Using Rainwater in Your Home

* Rainwater collection, storage, and use can help prevent soil erosion in the area where you live. This is especially true if there are many in your area collecting rainwater for use in different chores.

* It reduces ground water use. It’s worth keeping in mind that the water that flows out of the taps in our houses is partly or mostly sourced from ground water. Ground water is not an unlimited resource, and once it runs out, another source (usually in another area) will need to be sought. Imagine if this keeps going on for several years or decades.

By using rainwater in place of mains water, you lessen your use of mains water. The lesser mains water used, the lesser ground water that needs to be sourced for distribution. Purchasing large water tank can be a better option because the larger the capacity the more water will be stored therefore, you will have enough amount of water to be used.
