[Ferro List] Re.: Tank in Oblivia

[Christopher Glasspool]

Ron,
That isn't so big...I was thinking in the 50,000+ for a small community. For the laminated process, it will make it easier if you can slope the walls out slightly. I had some further ideas on stabilizing the sides; use whatever the local preference is for a building material and use this for a stay in place mold. It could be bamboo, mud brick, dry stack rock, whatever, just get  stabilized sides. Then look at it for applicability for direct fc work, or Naaman's idea of a stay in place weak fc mold. What I meant by bundling is to make panels of say three layers of chicken wire tied together, and push this into the mortar and repeat. I'm guessing that twelve layers will be OK (that would be laminating three times). Stagger the edges to the intermediate of the below bundle.
Here are some things you don't see even in commercial tanks and set up, but should be there for best effect. 1.) Slooped floor that goes to a clean out drain. Every tank needs to be cleaned out or maintained in some way at some point. 2.) Overflow outlet - nice to know that if something jams up downstream of the tank that it doesn't do damage upstream, or ruin a tank roof, whatever. 3.) A diversion tee just above the tank inlet. Whether it is to prevent temporarily bad water from going in, or whether you want an easy task of diverting so that you can drain and clean tank. - chris
