Installing a Sump

[Redwood]

I would seal off and abandon the flooded line to the ditch, and put in a pump station to lift the water to a new gravity line to the ditch that discharges above the flood in the ditch. this will maintain your drains in operating condition. You can't have tis line flooded.

I will drill small holes in the pit 1/4 in if I think the water level will go higher then the pit to keep it in the floor and they also help to drain water when the water level is down. From your original post I think you have drain tiles under your floor so this wont hurt anything. Make sure you put rocks around the pit

Here is what I would install in line from the house...

Thanks all for the info. The ABS sump pit, check valve and pump are installed and working fine. Hopefully the flooding won't occur again soon, but now I'll be ready.

The way I understand it is when the creek floods it pushes water back through the drain into the basement.

I hope the check valve is out side well away from the house and the valve can withstand the water pressure from the creek trying to get back into the house.

The pump if it discharges into that same line may be a problem...
