re: What's the Engineering Solution to NOLA Pumping?

This is legit what I am trying to figure out. Is it undercapacity in the system, or some other design problem? Or is it just impossible?

The current capacity I saw quoted this weekend was 1 in of rain in the first hour, followed by 0.5 in of rain per hour afterwards.

Here is the average monthly rainfall:



Based on those numbers, the current capacity is adequate for most regular storms. However, as evidenced by the levels of street flooding frequently seen during heavy rains, I'd say that the capacity should be improved. Unless, prior street flooding has been a result of the pumping system not operating at capacity.
