Sunday stills: Water towers or grain silos





http://sundaystills.wordpress.com/

I am stumped. I am married to a water engineer, and I don't have a single photo of a water tower, and I already used my sole photo of a grain silo.

When I was young in Borneo, we did have a lot of water towers, and we even have a  horrifying story. But that was before I entered the world of blogging. I don't have any photo from there.

I looked at my New Zealand archives, No, not one photo.  I ask you all to allow me to by default post these few photos.

Auckland has many volcanoes. Instead of water towers, we have utilised this precious gift of water from our volcanoes. Technically, our beautiful volcanic mountains are our "water towers."

Auckland's volcanoes and their eruptive products have developed some very valuable water resources. Not only have some explosion craters formed lakes e.g. Lake Pupuke, but basaltic lava flows have formed aquifers to become significant sources of water supply.

 Basalt lava flows are very porous and allow water to seep into the rocks. These aquifers are currently being tapped for water supply. For example at Onehunga, water "is extracted from four wells sunk into the One Tree Hill lava flows. An estimated 27 300 cubic metres of water per day flows through that aquifer, reaching from as far as five kilometres away." (Jamieson, 1992). Most of Auckland's volcanic cones support water supply reservoirs.

Very good job, Ann. Thanks for all the info on the volcano/water tower.

So, a local watertower is obviously a flexible idea. Had never thought about a volcano being a water resource.

Your stories are so wonderful! I have always wanted to visit New Zealand. I am glad to know more about extracting water from volcanoes.

We have a few extinct small cones around here. In fact, most of the nation's volcanic road base rock is mined about an hour south of us.
