I really think that like most HD stuff..
The rules are not as clear and specific as they should be.
Without clarity – in writing – too much is left to the discretion of the inspector … and the builder.
Here is how I read this…
Wastewater TANKS (plural) shall have a minimum capacity that is 50% greater
than the potable water TANKS (plural) —- not TANK (single)
As long as your hot water tank is no more than 3 gallons, or you use an instant tankless model, no prob.
And you are going to be selling rice – prepared using potable water…
So based on the next sentence, you are going to need the
Additional wastewater tank capacity equal to the equal to 15% of the WATER SUPPLY.
Does this mean your basic on board water supply?
Or are they referring to you bringing additional water for cooking?
Like a 5 gallon jug??
Are you going to have ice on board??
Again it wants additional wastewater tank capacity.
– PLUS 1/3 the volume of the ice cabinet ( whatever THAT is ) -ice cube tray? freezer? coleman cooler?
With the rules being SO strict down there…. just make sure you get 100% clarification.
I would think that a 75 gallon waste tank would be better.
Then you are covered if things change.
Maybe you do a festival, and need to grab extra water….
Maybe you run low on water, but things are busy, so the wife grabs you a couple of jugs at wally world and runs them down to you.
If you just squeak by with minimum capacity, you can potentially get shut down.
I have heard of it happening.
Sorry for soundin SO anal.
I only want to be helpful.
