Good organization here. That first problem was my first question, too. I'm working on rainwater collection and a water purification unit at the diner. Finally got it assembled yesterday, but I'll need to test it on purifying what's here before we start having fill ups. Still, it's only meant to be a back-up for a city treatment plant.

I should be able to start serving at least one meal a day at the diner when it's running properly.
