Pump Stations, Lift Stations - How They Work To Drain Communities

[@TheOnlySgtRock]

Interesting. Amazing the volume of those pumps.

[@whitemonkey7932]

I would never have understood the concept of the pumps changing over if you hadn't mentioned it a thousand times during this recording.

lmao

I'm in Memphis Tn and we have a series of levees around the city to protect us from the floods from the Mississippi River. At several location near the river there are pumping stations that do this but on a more massive scale. You can drive by them and see the grates. During low water times the water just flows thru the pumps. Once flooding occurs they will close the gates and the pumps lift the water over the levees. These grates have automatic cleaners that remove the debris collected on the grating. During the floods in 2011, these stations ran for about 4 months.

Thank you for sharing. That's pretty massive. 4 months is insane 😳

[@charliefunboy5210]

you would think those short cycles would be bad for the bearings, etc.

[@scottstrang1583]

Very cool.

[@rs-xr3ty]

You mentioned that it wasn't working for a long time but then it suddenly began operating on it's own unexpectedly?

[@FRENCHDRAINMAN]

It's on a float trigger. When the water is high enough, it turns on automatically.

[@dunlaoghaire1000]

Why is that all needed? What is going to happen, if all that ( dam, pumps, pumps house ) wili be taken away?

[@rajivunome]

It is design to keep the canal water level low so the storm water will be able to drain into the canal

[@KevinBenecke]

If there is a lot of water, can it turn both pumps on if needed?

[@FRENCHDRAINMAN]

They may do that I don't really know. I thought they alternate until on fails. The main station gets a warning light. They send repair technicians out while still on one pump

[@braintumor943]

theres a problem with this one, its stopped up, short cycling

[@FRENCHDRAINMAN]

I believe it's working correctly. The pumps Alternate

[@braintumor943]

Well these applications are usually set up as stages, you may have a lead and a lag but I will guarantee you no electric motor should short cycle like that, in no world is that a good thing, the on and off constantly hood on a motor

[@braintumor943]

My first guess, I can’t see it but I would guess There’s not good drainage in to the intake where the floats are, but maybe a control issue

[@braintumor943]

I would find a mechanical guy to look at it, but if you want to check it out, look at the floats or what ever controls the pumps, are there two of them at different levels, I bet so

[@mikeelliott9469]

If powered by electric motors, this short time, start/stop operation , is very expensive ! start up uses the most electricity and as the pump “primes” the motor runs more efficiently ! …..js

[@mccarag13]

Damn, guess the cities failed and thats why Grosse pointe flooded.

[@mccarag13]

Is this Connor creek?
