I'd need to ask more questions. Is this supply connected to a separate
meter? If so, why is there a separate meter from the domestic?
One local water district requires a landscape meter. This includes outside
fawcetts. They bill this water at a higher rate during the summer dry. They
also can shut off all outside water during dry years, and leave the homes
habitable. Their groundwater supply is marginal during drought.
Which goes to the second issue. From when 13-D first arrived on the scene
two reasons have always been given for using the domestic supply for the spk
supply. Cost. Reliability.
The reliability position has always been that if the toilets can't flush
people won't stay in the house long. A shared supply has always been
considered more reliable for this reason.
People can easily live in a home forever with the irrigation turned off.
So the parties involved (design-build firm, owner, FP office), would need
to determine reliability is adequate.

I've never used a set up like this but start with the water supply chapter
in 13D. Talk to your local fire guy, he may be able to tell you in 5
minutes what to do. Since it's been done already, don't re-invent the
wheel, learn by what's been done before, and design it better.
You may have to worry about sediment, and chemical compatibility due to
run-off, fertilizers etc... with the system material in the house, but that
could be checked by a testing lab, and including a strainer on the incoming
line. The irrigation system if it is using a tank, would most likely
include a pump, for which information should be available. You could test
the pump discharge, much like you would run a pump test on a fire pump.
A system like this would be an interesting challenge. You have the added
plus of not having to deal with the BFP, additional pressure loss, and cross
connection regulations.

Subject: Can a 13D system be connected to the U.G. irrigation supply ?
Can a 13D system be connected to the irrigation supply in lieu of the
traditional U.G. arrangement of connecting at the domestic water meter ? I
have an unsprinkled house that I am being asked to sprinkle in the same
manner as the other sprinkled houses in the subdivision; these houses are
not connected to the U.G. at the water meter but are rather connected to a
curb stop that is reserved for irrigation water. The irrigation main does
not tie-back into the city water main so I have no way to gauge the water
supply by flowing and testing a hydrant. (These are single family residence
houses, not townhomes....)
Is this even allowed ? I cannot find anything alluding to this and the AHJ
has never heard of anyone doing this before. I think the rationale behind
doing this was that it did not conflict with the potable water supply and
was considered to be "free" water.
Can anyone shed any light on this and if so, what are the requirements and
where can they be found in 13D ?
