How thirsty is your lawn?

This summer many of us will struggle to pick between a not-so-green-lawn vs a not-so-affordable-water-bill.

Before making this choice, how about answering this question: "How thirsty is your lawn?"... How do you know how much to water it if you don't know how much water it needs in the first place?

A good majority of us don't relate to this problem since they are not the one who waters the lawn. It simply is someone else's problem, or is it? Shouldn't we be asking the person in charge to answer the question?

OK. There is a way to do it right. It starts with knowing what causes your lawn to need water. Ever heard of ET? ET is a measure of evaporation (from soil and plant surfaces) and transpiration (from plant tissues). So it can be used to calculate how much water your lawn needs.
