Sound 2 - Sewer Drains

I was crossing the street and heard some water flowing almost like a creek. What made it odd to me was I was in the middle of the city and there was no creeks where I was. I noticed the sound was coming from two sewer drains that had water flowing into them. They where on each side of me so my mics picked up to different sound of running water. Here is what it sounded like.
