The large pumps are rated at 1,800 cfs (cubic feet per second), which translates to almost 1.2 GPM (gallons per minute). “An Olympic-size swimming pool holds 660,000 gallons,” Claxton says. “So with the 1.2 million GPM pump, you’ve got about 30 seconds to get out of that pool.” The small pumps have half the flow rate—“only” 900 cfs, or about 400,000 GPM, he adds.

they want to do that with the comite diversion canal but stopped construction
This construction was stopped because of Hurricane Katrina. They were in the middle of constructing it when Katrina hit. All funds were pulled to better develop New Orleans. That is a big reason why the diversion canal sits partially dug right now.

Many of the raised basement homes are being converted to full height, ground level first floors. It get that it's cheap sqft to add, but many of the houses built like that took water in Katrina (edit: with minimal damage as a result of the design). The updated flood maps have x zones in raised basement neighborhoods.
We have short memories.

True.
But from what I have seen personally, the bottom floors are being built-out to withstand minor to medium depth flooding.

It would flood some spots, but the water would get out much quicker

t the start of the 21st century Pumping Station 6, or the Metairie Pumping Station, astride the canal had 15 pumps capable of moving over six billion gallons of water a day through the station. Run off from substantial areas of Uptown New Orleans, Metairie, and surrounding neighborhoods drains into the canals and basins on the River side of the pumping station, which pulls the water up into the portion of the 17th Street Canal flowing into Lake Pontchartrain.
6 billion gallons a day.
4,166,000 gallons per minute between the 15 pumps
thats 277,733.33 gallons per minute. i was way off

The only portion that was really close to being complete was the Bayou Lilly Control Structure just west of highway 61 and just south of Port Hudson. If you have google earth the coordinates are 30°37'13.25" N 91°14'22.92" W

I bumped the Comite Diversion thread and added this. This will show you exactly where.

Orleans will be complete early 2017 and 17th/ London late 2017. The interim pumps will remain until new stations are operational.
Posted on 8/18/16 at 4:58 pm to The Cow Goes Moo Moo
So the plan for the interim pumps is for removal? Why not leave these $30-50 million dollar pump stations in place as backup?
ETA: Doesn't Kiewit have the permanent pump station contracts? I know they did the Orleans interim and Mr. Go.

Good thing would be the water doesn't sit in the homes for 2 weeks like Katrina.
Be informed before you post, there's a big arse thread on the Alligator Bayou flooding.
Water is still rising at my parents house and won't be able to go down for 2-4 weeks..........ya dick.

Keiwit is one of the contractors in the joint venture. The old pumps will be used to at older pump stations that require maintenance.

Hopefully they fixed all the issues with those MWI pumps initially installed. There is still a lot of money put into those stations besides the pumps and motors. Still have the actual structures, needle gates, field house, etc...
Fun fact. The original plan for the interim stations was to have a guy sitting onsite with a picker and that is how the gates would be raised or lowered during emergency situations. They ditched that and went with hydraulic controls.
