Hi, I hope this is the right forum for this question. I'm part of a multi-building condo complex.

I have an outside stairwell leading to the basement on each building. Many times a year, tree-droppings and mulch get washed down into the bottom and clog the drain. If the debris is enough, it covers/clogs the six-inch flat drain, and the water backs up and goes inside the basement. All I have to do is brush the debris away, and it drains, until the water pulls the debris back in.

I thought maybe I could get a domed drain there instead of a flat one, so that it doesn't get clogged. But the ones I'm finding are a few inches high. I want it to be maybe an inch high, because the drain is right in the middle, and there's not much room to move around. I also want it to be metal, in case someone stands on it. And I want it to be rounded so it's easy to maneuver around, for example if people are moving boxes or furniture through there.

I haven't found anything quite like this in stores or web searches. Can you suggest a drain that works here? Is there another solution that works better?

 

You're pretty specific in your wants. Since the drain portion is already in concrete that much is fixed so you're stuck with grates that will fit it. And most grates come with the drain as part of a pair.

1. You can just leave it is and continue to clean out the drain periodically.

2. You can make or have made a separate screen that sits over your existing to filter out debris. On the high end you could have something cast or machined. On the cheap side you can make a screen out of hardware cloth.
