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. Jamie Seidl

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 ?
