I am not sure if this is the right forum, so if its not it can be moved. Its a little bit of a weird question, but I was hoping maybe I could find some information. We bought a house a few years ago. It is in the country and has the typical sump pump well setup. However, randomly one day the wife of the family who built the house was passing by and stopped to say hi. She mentioned something about them not wanting to put a sump pump in when they built the house. I cant remember exactly what she called it, and im kicking myself for not asking more questions . I swear she said they put in a natural drain or something like that. She pointed out that there is a clean out for it out back by the field. There is definitely a large pipe by the field with a stone cover on it. It sounded like they ended up going with that, but had to do a sump pump as backup. Does this sound crazy? Is there anything like this that someone knows about that could point me in the right direction? I would like to be informed about it, but unfortunately i didn't get her number and cant find much on what it might be.
