The entrance Brewer "B" Drain is located down river a short ways from the Brewer "A" Drain. Though we call it "Drain B", the sign on the shore says something like "waste water run-off drain #03".

This drain starts off with a section of dry concrete pipe, large enough to walk through with the standard bow-legged-squaty-gate often used in tunnels that are about two or three feet too small to stand up strait in. As we said, the tunnel is dry, but the sound of running water can be heard off in the darkness ahead of us. The tunnel goes strait in for about 75 yards and ends with a short section of wall, at the top of which, the wall slopes up and away for about five feet at a 45 degree. Right above this slope, a sturdy enclosed matal pipe bisects the tunnel from one side to the other. Looking up, we can see that the tunnel opens into a room above us. It is an easy climp up over the pipe and into the room above.

This room is obviously designed as a sewage run-off room, with the overflowing sewage, running out the dry tunnel we entered through. The room is about 20' square, with the tunnel we just came in from opening down in the lower right hand corner. The room is essentially divided into quarters by a short wall and system of troughs in the floor. The short (about five feet tall) wall is just to the left of where we came into the room and cuts about half way across the chamber. From the center of the wall opposite the one we came in on, or directly across from the end of the short wall, is a cement "mummy" tunnel which drains water into the troughs in the floor of the room. One trough comes out of the "mummy" tunnel and intercects in front of the short wall with another trough which cuts the room in half, creating a sort of "T" of troughs in the floor. The troughs empty out into two small tunnels (1' and 2' diameter) on each side of the room. There is some nice brickwork on the floor in this room, by far the best brickwork we have seen in a drain. There are also three solid, heavy looking manhole covers; some sort of electrical box things hanging from the wall near one of the manholes; and a metal ring hanging from the ceiling, purhaps for workers to clip a safety line onto. The area near the manhole covers smelled strongly of sewer gases. We explored this drain during the winter, the gases would likely be much worse during the summer. Expect to see human waste and other such things in this room... big clots of it in fact. Despite that fact, it is quite a nice little room. We suspect that the small tunnel on the right while entering through the run-off drain might connect up with the first intersection room in Drain A.

Looking up the mummy tunnel from the room, some sort of manhole room or intersection can be seen not too far up. Being not entirely well equiped for a sewer adventure, we only explored up the mummy tunnel about twenty feet to find out what kind of room could be seen ahead. It was nothing interesting, just a small manhole room, with the mummy tunnel continueing on strait past it.
