New York City Subway [SEP] Subway flooding
This was the third incident in 2007 in which rain disrupted service. The system was disrupted on this occasion because the pumps and drainage system can handle only a rainfall rate of per hour; the incident's severity was aggravated by the scant warning as to the severity of the storm. In addition, as part of a $130 million and an estimated 18-month project, the MTA began installing new subway grates in September 2008 in an attempt to prevent rain from overflowing into the subway system. The metallic structures, designed with the help of architectural firms and meant as a piece of public art, are placed atop existing grates but with a sleeve to prevent debris and rain from flooding the subway.
