Hi Susan. Romani Landscaping did the beautiful hardscape on this job, so they will be able to answer your question.

Hi Susan - Thank you for your question. That drain is a deep concrete catch basin with an iron grate lid on top. There is no pump inside....the yard is gently pitched to that corner and once the rain water level inside reaches a certain height, it exits through pipes that are connected to that basin. Hope this answers your question! :-)
