here. Its about 30 minutes long and we learned a ton of water facts that are mostly useless but very interesting. Back in the day when the cistern was Houston's only water usage there was a point where the water was deemed unsuitable for use by anyone, including the fire dept. The cistern did not only supply drinking water but was also very important to the HFD. The government knew for a while that the water wasn't always good to drink but they let it slide... proving the government has always made poor decisions regarding public safety.
We had really awesome high quality images that got lost when our SD card reformatted... switching from sony to cannon cameras is apparently a no-no. It corrupts all of the images. To see this beauty, you might have to pay 2 dollars for a tour... It's also free on Thursdays, but reservations are required.
They will be holding tours in its current state for a few more months and then it will undergo an awesome transformation. The city will be transforming the space into a light and sound themed exhibit. They hope to have it together by the Superbowl. I can't wait to go back again once the installation is complete. It's a beautiful must see literally underneath the heart of Houston.
