What Affects The Ground Water Level

ground water levelSomething my daughter’s father in law mentioned to me made me reflect on what causes the ground water level to decrease.

He lives in a fairly affluent area in Melbourne, Australia that was previously, about 50 years ago, when he bought his first house was a fairly lower social/economic area. This area is only 5 miles from the CBD. Consequently over the past 50 years the land values in this area have risen dramatically some average sized blocks now fetching almost a million dollars.

Getting back to the point and how this relates to green energy this man is an Italian immigrant who true to form sectioned off the back half of his property to grow his veggies and plant his fruit trees. He mentioned to me that he now has to water his vegetable garden almost every day whereas until recently (starting about 5 years ago) he could have gotten away for once a week if there was no rainfall.

It wasn’t until I took a stroll around this leafy suburb that it hit me what the probable cause for this. (including the allowance for maybe reduced rainfall due to global warming). Time and time again I passed new rows of houses that were huge. It wasn’t the hugeness that made me think, it was the fact that these houses virtually covered the whole block in which they stood. Now think about this, previously there would have been a reasonably sized family home on these blocks covering maybe one third of it. This meant during a rainfall most of the rain fell onto the ground and slowly sank down to the ground water level. The rest fell onto the roof into the drains and then out to sea. Because of this the ground water level would sink lower and lower.

What do you thing these monstrosities would contribute to the ground water level? Virtually zilch because most of the rainwater would fall on the roof, into the drains and out to sea. A minute amount would fall onto the meager amount of ground exposed.

So is this the reason that this retired gent found he had to water his garden more often? More of these ground gobbling monstrosities are being built around him. The more affluent want to find a block of land that is close to the city. Sometimes beautiful houses of age being razed to the ground to be replaced By these monstrosities. They are often replaced by houses that seem to have no architectural design at all.

Thinking further ahead to what the fall of the ground water level will cause. One other attraction to this area is that it is “leafy” thus the term “leafy suburb” All the streets are lined either side with beautiful trees. As I roamed around I occasionally notice a fallen branch. The particular trees where planted many years ago and were known for their longevity. They had hardly ever dropped branches. There is only one way that these type of trees will drop branches and that is if they are “stressed”. So what causes trees to become “stressed”? The lack of water! Trees have deep roots that extend to the ground water level. If this drops then the lack of water will cause this.

As more and more of these ground-eating houses are built the worse this will get. I envisage, at some time in the future the people who had these houses built will find that they are no longer living in a leafy suburb but a barren one. If they wanted a place to live without gardens, why didn’t they buy a grand apartment?

I guess in the main it’s only to exhibit wealth, “I need a monster of a house to show how affluent I am. It’s not what I need and stuff the environment” ground water level, what is that?
