Looking for ref for design of slabs of water and waste water tanks.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Waste water Tanks
You need to get the PCA publications "Design of Rectangular Tanks" and/or "Design of Circular Non-Prestressed Tanks." Also, you need ACI 350-05.
But if the slab supports the walls and doesn't leak, it's done its job.

I will design the slab as a structural slab using plate coefficients with load distributed from the walls. I will not account for the load from the liquid since it will transferred to foundation directly through slab.
I will assume fixed conditions at wall interface and compare that to wall fixity and design for higher moments. I assume wall moments at wall/slab bottom end will control. For positive moment in slab I will assume hinged condition. I will also take into account uplift forces.
Do you agree with this approach?

I think you will be able to design this, now that you have the PCA reference. If you are in a seismic area, there is also a design reference on the seismic design of tanks.

You stated you got the PCA references. Did you get a copy of ACI 350 as well? For wastewater tanks ACI 350 has design requirements that you may not find in the PCA books.
