still is a fun idea to kick around. HDPE is a great plastic that is less expensive than plexiglass and also more durible.

more of a triangular shape would help stability. The wall would probably have quite a heat gain, nice for watering in cool weather.

Feezing problems would lessen w larger volumes

I agree.

The average family uses 400 gallons of water per day.

This tank is supposed to be for watering a garden however.

Yes but you could lose a great deal of volume.

Depending on your soil you could perhaps have a ten foot fence with 4 feet of the fence buried below ground to provide stability. It could save on concrete and increase your storage volume at the same time.
