When Main Water Lines Break

From the title, I'm sure you can guess what this blog is about. I had a very interesting weekend. We had a small crowd of volunteers this weekend to help fix some things up. On Sunday, we had some sewer problems in the chapel. This usually comes from a holding tank in the cafeteria being full. That's where the chapel bathroom drains to. We usually pump it out into the main holding tanks buried in the courtyard. Nothing unusual so far, but then we started to have some overflow out of a crack in the cement. This flooded a hallway with raw sewage.

As it turned out, this 'overflow' behavior was normal here, but the problem was that it was not draining. We happened upon a vertical pipe that a child had shoved a small board down, blocking the flow. OK, so now we solved the overflow drainage problem.

Next up, we were thinking about why the tanks were filling up so quickly. After some consideration, we decided that the laundry room, with 4 washing machines going nearly every day, should not empty into the septic system. All that 'gray' water was filling up the holding tanks too rapidly.

We found an empty and unused holding tank in the far corner of the complex. It was a long way off, but we ended up routing a drain from the laundry room, 160 feet (including some vertical drop) to teh empty and unused tank. Fortunately, the laundry room was on the 2nd floor. It was quite a project, but did that bust a main water line? Read on.

Here in Chapultapec, the water pressure sometimes goes down to nothing ("nada" in Spanish). For that reason, most places have a holding tank for water and when the pressure goes down too low, you just use that reserve. Our reserve is about 500 gallons and with all the people here, it is gone in about an hour and a half. We had two 1,000 gallon tanks on the second floor, but they were both hooked up to the old water purifier that hasn't been working for years.

We decided to go ahead and hook all the tanks up together by connecting the pipes on the bottoms of the tanks. A great idea! Well, in doing so, we lifted the now very light 500 gallon tank and didn't notice the stress it caused on the main water line that connected to it. I'm on my hands and knees connecting a 'T' and 'SHHHHHH' water everywhere. And nobody could get the water shut off! I didn't have the right size to slam a cap on it. What a mess.

Someone ran to get the replacement pieces, and some others tried to find the shutoff. While they were doing that, I went ahead and hooked up the rest of the pipes for the storage tanks.

After getting the plumbing parts, elbows, T's, pipe, SHUTOFF VALVE, we got it all hooked back up. Best thing is that now we have a good 2,000+ gallons of reserve water. The third tank is on a little higher elevation than the other two, so it doesn't fill all the way up, but it's a lot more than we had before.

My next post will have to do with the solution to our ELECTRICAL nightmare from last week. We found the problem.....
