[pre]first of all I’m from peru work for company AQUAFIL this company is specialized in wastedwater treatement plants,we biult steel tank for wastewater. acoording to awwa d100 standard say that should use thickness of 0.25" all parts of the structure in contact with water But we’re using thickness of 3/16”. Acoording to what I’ve read AWWA d100 standar say : the awwa standard usally contain options that must be evaluated by user of the standard, in other words could have trouble with awwa standard . keep in mind we’re using this standard five months ago

Bottoms plate is normally 1/4" minimum regardless.

The AWWA Standard is a voluntary standard. Were you required to construct this tank to the AWWA D-100 standard?
There are other aspects to be considered, foundation, seismic, etc.

I know it's much better to use thickness of 0.25" than 3/16".But keep in mind If I use thickness of 0.25" the budget of cosntrucction steel tanks will be high.but don't worry, when the construcction finish must be tank surface preparation internal and external acoording to SSPC-SP5 STANDARD, after that we have to cover whole the part internal of tank with FIBERCLASS, so getting a thickness of 1/8" this process is standard for the company.on the other hand here in peru we use thickness of 3/16" steel tanks for wasted water storage is standard
anyway thank you for your tip
best regards
