Sustainable source of water

Rainwater collection systems “harvesting” offer both residential and commercial properties an invaluable source of free water. These tanks are made to collect and hold rainwater, which is then used for a number of different things like drinking (when tested and considered safe), irrigation, and other uses, like washing your car. There are many different sizes and shapes of rainwater harvesting tanks.

The rainwater harvesting tanks are made to collect and store the water, whether it comes from the roof directly or via a system of gutters and downpipes. A variety of uses, including irrigation, drinking, washing clothes and dishes, flushing toilets, and other household requirements, can be made of the rainwater that has been collected and stored. Rainwater harvesting tanks are available in a wide variety of sizes, shapes, and capacities, ranging from modest residential tanks to substantial industrial sized cisterns.


There are many advantages to collecting rainwater. It serves as a low-cost source of water that is free from contaminants like fluoride, chlorine, and other impurities present in the water supplied by some water utility companies.

Benefits of storing rainwater

By offering a different source of irrigation water that is less likely to wash away the nutrients from fertilisers than conventional overhead sprinkler systems, harvested rainwater also assists in reducing soil erosion.


It is always a good idea to calculate the tank capacities, and one helpful way to do this is to go to the websites of different harvesting tank suppliers who have free-to-use online calculators available for that purpose.

Tank variations

On almost any type of property, rainwater harvesting can be done with little expense or effort. The simplest form involves installing a tank or cistern to collect runoff from various roofs and gutters in an accessible location, like a basement or backyard. More sophisticated systems, such as pump assemblies, filtration devices, storage tanks for grey water separated from potable sources, and even aquaponics systems for food production, may be required for larger properties with more complex needs.


No matter the configuration or system of tanks you purchase the basic idea will be the same, no matter what kind of final components you purchase:


Catch the rain before it hits the ground, filter it, store it, then use it wisely!


Homeowners and businesses can benefit from the advantages of free water while assisting in the preservation of their local environment by using proper planning and installation techniques.
