The Right Water Tank Size for Your Home The Right Water Tank Size for Your Home

Determining the water tank size for your home need not be too difficult. In considering a rainwater or grey water collection tank for environmental purposes, you’ll want to consider a variety of factors.

How Many People are in the Home?
Each person in a home uses between 30 and 130 gallons of water each day, depending on age and habits.

If you are installing a grey water collection tank, then the more people in the home, the larger the tank you’ll want. There will be more water to collect.

For a rainwater collection system, you’ll want to consider how much water you use each day, so that you can have enough water to replace it during the dry season or simply to save water. Again, the more people in the home, the larger the tank you’ll need.

Support

Water tanks can be very heavy. You will need to consider the weight of the water and the tank before deciding how large of a tank you’ll want to install.

If the tank is to be located above ground, make sure you have the concrete support or stand support necessary.

Amount of Rainfall

If you are using a rainwater tank, consider the amount of rainfall typical in your area and the length of drought periods. If you have a great deal of rainfall and could store enough water for the entire drought period, get a larger tank to accommodate it. If not, don't waste the resources.
