|  | 29 May 2013: Topless Tanks
 
 | 
|  As we have stated previously, we are going to be taking the ideas  developed in this column over the last couple of years and developing  them into design practices.  This is how it works.  We will provide the  basic narrative here for one design practice each week.  We will keep it  open for comments for one month.  After that, we will finish it in  formal form and offer it for sale at a modest price.  Here is where you  come in.  If you make a substantive contribution to a standard, the  organization for which you work will be granted a pro bono license to  use that standard with its current issue number for as long as you  like.  We have had good response so far!  Contribute, please.
 
 This week's: Topless Tanks (LGM 2013.021.01
 when issued)
 
 Reference:
   In warm climates, it is customary to build tanks, even outdoors, without tops. This idea can be applied anywhere.  Objective:   To use Topless Tanks.   Consideration:   In colder climates, in order to keep out snow and avoid heat loss, the tank may need to have a custom fabric cover out of sail cloth or similar material.
 
 Cross bracing is required to help the tank maintain its shape. Additionally, the cross bracing may need to be slightly concave to make sure materials (snow, debris) can easily slide off the top.
 
 Such a top can be removed for full access and replaced every few years. It will certainly be less expensive than metal, be the metal stainless, carbon steel or aluminum. |
