Any sump pump specalists?

Quick description.
Had a metal all in 1 bulkead/steps unit removed 7 years ago due to it rotted being against the earth so many years since 1965.

New guy dug out a box like area, put in footings and 3 cinder block walls.
During heavy rain season the floor/pit would fill up with water. I tried that paint on dry lock. did not work, I tried heavy plastic allong outside walls did not work.
So I added a 1.5' cement threshold making it a 3" pit to buy me time to pump it out with a flow tech portible pump. Me PLAYING water boy gets OLD fast!

When the pit overfills it overflows into cellar.

Can a sump pump work being in a cold unheated bulkhead pit? I would also rather pump the water into the house sewer via a hose. My worry about pumping outside is pipe or hose freezing up with no place for the sump pump to push it.

Anyone up north with this issue?

If it's not frozen the pump shoudl work fine. Your output line needs to be 4 foot under ground to prevent freezing. Do you have septic or city sewer? Don't think you want to put that much water into your septic system...

I have never seen the water in the pit freeze then again I don't always check.
I figure if its getting in there it has to be above freezing so that means a SUMP PUMP should be able to suck it out.

i have city sewer = NICE
