The rain pounded down, more than seven inches by some estimates, inundating streets and spilling into cars, homes and businesses. For many, the same thing had happened only two weeks earlier.

Fear and dread gave way to anger, as residents demanded to know whether the city's network of drains and pumps were doing all they could to keep us dry. The City answered with assurances. The head of the Sewerage and Water Board, the agency tasked with pumping out the water, told us the system was working at “maximum capacity” and that it was just too much rain for any system in the world to handle.

Those assurances soon drained away faster than the floodwaters. The city admitted to a host of problems. Pumps weren't working. Massive but ancient turbines were unable to generate electricity to send to the pumps. Others weren't even turned on for hours as neighborhoods went underwater.

How could a city built below sea level allow its drainage system to deteriorate to this condition? Eyewitness News assembled a team of veteran reporters, researchers, experts and insiders to launch an investigation, unprecedented in its size and scope, into the Sewerage and Water Board, and the city's handling of its drainage system.

We found that hundreds of millions of dollars meant for the drainage system, along with public confidence in City Hall has gone down the drain.
