I've noticed that my sump pump is constantly running—about every 15 minutes. It's currently draining into a gravel area by the sidewalk, but there's just too much water, and it flows over the sidewalk, leading to algae and mold growth making it dangerous. I can't just pump it elsewhere as that causes flooding in different spots. The pump is equipped with an overflow safety that directs excess water to the storm sewer if needed, which has been a lifesaver during pump failures. In winter, I turn the pump off and rely on that safety feature. I'm considering putting a timer on the pump to let it dry out and potentially reduce mold, but I'm worried about flooding during heavy storms if it fills up. I'm hoping to find a smart plug that responds to water levels so I can have a timer while still being safe. Any ideas or suggestions?

I’m a bit of a newbie when it comes to sump pumps, but why not just pump into the storm sewer? That sounds like a decent option.
Yeah, many places have restrictions on that. Even if there weren't, pumping directly could overwhelm treatment plants and cause backups.
Have you considered adding a second sump pump? You could install it with a higher float valve, which might help with the drainage issues you're facing. It could provide some backup if the primary pump struggles.
I'm not sure a second pump would help much. I think a backup is unnecessary since the main pump is constantly running and that's not the main problem for me.
If your sump pump runs all the time, it could be due to a few reasons. It's possible the sump was placed too low, or the overall water table in your area has risen, especially if you're near a slew or low-lying section. It might be worth getting a pro in to check out where the excess water is coming from.
I definitely live in the lowest point of my street, and the city says the water table has been high lately. So yeah, I guess I'm just pumping groundwater! I just need a solution to get rid of it.

If the storm sewer backs up during storms, it doesn't really do me any good and can actually lead to flooding. Plus, it's against code here unless I have a permit.
