A cross-connect is any connection between facilities provided as separate units by the datacenter. In other words, if you rent a cage, you can run cables betweeen your various racks and they are not really considered cross connects. But typically a user facility is a rack. Consider the uplink to a network provider. The line that runs from you to the telco's rack is a cross-connect. Any other between-rack cable run falls in this category. Even if the datacenter is bundling network access, it's still a cross-connect. (It's also typical to have a meet-me room that is the center of all the cross-connects, it's a patch-panel room or cage.)
Water recycling is the process of taking effluent (wastewater and sewage) and treating it so that it can be reused. For potable (drinkable) use, the recycled water has to be treated to a sufficiently high level that it's suitable for human consumption.
The energy we waste using bottled water would be enough to power 190,000 homes2. Americans used about 50 billion plastic water bottles last year. However, the U.S.âs recycling rate for plastic is only 23 percent, which means 38 billion water bottles â more than $1 billion worth of plastic â are wasted each year3. The recommended eight glasses of water a day, at U.S. tap rates equals about $.49 per year; that same amount of bottled water is about $1,400.
