The Engineering Crew at the 9/11 Memorial Pools

In the spots where the World Trade Center towers once stood, there is now a memorial to those we lost on September 11, 2001. It includes a museum and two massive pools of water below ground level, about an acre each, with waterfalls all around. The names of 2,983 victims from both 9/11 and from the 1993 WTC bombing are inscribed on parapets surrounding the pools. When the memorial closes at 8PM a dedicated crew gets to work maintaining it. This means cleaning the water, which collects leaves, dust, and debris every day, including some trash. They also brush up the algae and filter the water. The bronze plates with the inscribed names are also cleaned, and sometimes they have to repair acts of vandalism. The crew takes their work quite seriously, to make sure this sacred space is pristine when more visitors begin to arrive every morning at eight.

The National September 11 Memorial & Museum will hold special events for the 22nd anniversary of the 9/11 attacks. The schedule is here. (via Laughing Squid)
