Filthy water --> Drinkable

TED is my favorite website and you can always find interesting talks almost about everything. Today I was watching this talk again! (I love robots) and I found this talk by Michael Pritchard about making filthy water drinkable. 

Here is his website.

Mamloo Dam construction

I was director of SACES (Scientific Association of Civil Engineering Students) at University of Tehran and we planned many talks, field trips and colloquiums. In one of our filed trips we visited a soil dam 45 km southeast of Tehran. I was looking to the map of rivers around Tehran today and found that they finished the construction of the dam and already using it. Name of the dam is Mamloo soil dam and it receives water from two rivers from north and northeast of Varamin; and the main river is Jajrood river which supplies some water of metropolitan Tehran. You can look at the location of the dam here (google maps) or download the kmz file here (google earth). Here are some pictures before finishing the construction when we visited the site (Pictures are big in size so you may download them if you want to have a closer look).
