we had a law pass in 2008 that allowed gray water in buckets Text is at end.
we also have gray grey water for toilet flushing. not sure what my charlotte, nc will allow.
I have emailed them and waiting back. I'm guessing toilet flushing only.
so here is my question what kind of dye and chlorine system can I put in a 120gal tank to meet code?

Code:
A third type of graywater reclamation system has been legal in N.C. since 2006. It is a current legal plumbing code in the 2008 International Code Council and International Plumbing Code book, volume 1, plumbing code. There are very strict guidelines to follow. Here are a few of them:
No less than a 50-gallon tank may be used.
No more than a 120-gallon tank may be used.
Vent, drain and waste must not be intermingled.
There must be a separate water supply line from the graywater supply line.
All graywater piping must be labeled as unsuitable for drinking.
Reclaimed graywater can only be used for water closet and urinal flushing.
Chlorine and green dye are required.
SECTION 14.(c) Notwithstanding G.S. 130A-335(a), untreated gray water may be used in periods of drought to hand water trees, shrubs, and inedible plants on single-family residential property under the following conditions:
(1) Gray water shall be applied as soon as practicable. Untreated gray water should not be stored for later use.
(2) Gray water containing hazardous chemicals including, but not limited to, residue from solvents shall not be used.
(3) Use of untreated gray water is restricted to the residential property where the gray water originates. Untreated gray water shall not be allowed to run off onto adjoining property, roadways, or into drainage features such as ditches and storm drains.
(4) Untreated gray water shall be applied using buckets, watering cans, or other handheld containers. Gray water may not be used in an irrigation system unless the gray water has been treated in accordance with standards set out in the State Plumbing Code.
(5) Gray water shall not be applied closer than 100 feet to surface waters or a water supply well.
