Case studies   King Street Center   The King Street Center in Seattle, WA is a great source for water reclamation, along with many other green technology elements in the construction and maintenances of the building. Water reclamation can be apart of the greywater system, but here at the King Street Center it is a stand alone feature.           The main feature and purpose of this system is to capture rain water on the roof and then filter through a series of three tanks which in the end would then be used to flush toilets and run other water features in the building. But after this the water will enter the city sewer system, even though much of this water could be captured again and reused for many of the same functions. Only the blackwater would have to leave the building, unless it went through a much more intense filtering system, but that might not be the most effective use of money.
