Efficacies & Inefficacies of Rainwater Tank Installation

Rainwater is a natural and free source of fresh water.  Harvesting rainwater in a tank gives you a personal supply of water to use during water restrictions and can help you to reduce your water bills.

A rainwater tank is also called Rain Barrel in North America or a Water Butt in the UK. It is a tank to store and collect rainwater from rooftops via pipes.

Rainwater harvesting/collection system can yield 623 gallons of water from 2.54 cm of rain on a 1000 sq feet roof. It has many environmental benefits.

Rainwater tanks may be constructed from materials like polyethylene, concrete, fiberglass and stainless steel, galvanized steel which are rust and chemical resistant.


  • Multipurpose:

Rainwater can be used for all sorts of things from flushing toilets, to washing clothes, cars, to keeping the garden freshly watered. These tanks are installed and used also for drinking and retention of storm water.

  • Reduces Use of Scheme Water:

It reduces the use of main’s water – very valuable limited resource. Rain water falls for free and if you are able to store this vital resource then you can use it for your household chores and lower your water tax. If you look for ways to lower your carbon footprint then this is the best way. Save water, use it wisely and use it well!

  • Cost Reduction:

It helps in saving some money by buying less water from a service provider resulting in water tax reduction. It also provides cost-effective on-site detention of storm water. Now, some people might find it difficult to adjust with rainwater tanks completely while many on the other hand thank the rainwater tanks for lowering the bill at the end of every month.

  • Self-Sufficiency:

Rainwater can aid self-sufficiency providing a backup supply in case of water restrictions caused by drought or shortage of water. If you rely on government resources, then you end up paying bills for the same. The government can at any point of time restrict the water supply in your area calling it drought or any other natural calamity. When you are self sufficient you will be sure of the quantity of water you have stored and take all the measures that it last.

  • Better Quality:

Rainwater being chlorine free can provide a better quality portable supply than mains or dam water. The river or dam water is polluted. It reaches the city water filter system and is treated with chemicals. The water you are using daily from the government source has been treated chemically to be fit for human use. Whereas, the rainwater is still known to be the purest form of water as it is free off chemicals, and other impurities.

  • Reticulated Water Use:

Reticulated water use can be reduced by 50 to 100 percent in urban areas and this can help to reduce the need for new dam construction, the energy used in pumping water, infrastructure operating cost and also can help to protect remaining environmental flows in rivers.

  • Reduced Levels of Salt:

As it is natural and unprocessed water available for use it has reduced level of salt and other minerals.  The chemically treated water has a number of minerals and increased level of salt which is unfit for human body. This is the reason why there is a need to install drinking water filters at home. Rain water is pure and does not need to be filtered for human use as it is a natural source.

Most rainwater catchment tanks are used throughout the world are composed of virgin polyethylene. Each type of tank has positive and negative aspects as stated earlier.
