Like Travis and Richard said.....it's just a drain for overflow in your sump. I use 3/4 inch PVC and a garden hose for mine. It's never not worked in 2-3 years now. The garden hose is looking pretty sorry, though.
You're DRIPPING water in the tank, at 2-3 gallons per hour, and so the overflow drain in the sump will trickle water down the overflow, through the hose, to the drain wherever it is.
So .... how likely is it that the garden hose will get completely restricted, and when will gravity stop working. It's really that reliable--has to be.
And, I'm well over 6 months on my filter cartridges right now, still no chlorine/chloramine in the drip.
