Choosing Your Perfect Tank Size

November 18 by : admin

Have you decided that you want to install a rainwater tank in your house, but are confused about the size that is perfect for you? Well, most of us are, and here are some points that might help you in deciding the tank size that is perfect for your house.

  1. Collection area: To calculate your runoff, 1 millimetre of rain on 1m² will deliver 1 litre of water into your tank.
  2. Number of occupants in the house: It is important to understand that even if the house is small, with more number of occupants or regular guests, it is likely that the amount of water will be higher.
  3. Your internal and external water use practices: By connecting your rainwater tank for internal use in the toilet and laundry you will increase your rainwater tank’s yield.
  4. Rainfall in your area: It is important to know the amount of rainfall your area receives every year so that you can understand the maximum collection your tank would be able to do.

To know more about rains in your area, refer to the picture below.Bureau_of_Meteorology

Calculating the appropriate size:

Use the following formula to know your maximum capture capacity:

Roof Area X Annual Rainfall = Maximum capture capacity.

Then, using the following formula, calculate your need:

Most days without rains X Average daily water use = Storage volume required for one day.
