In most cases/places, the sprinkler water is considered gray water, and it would be OK to discharge a sprinkler drain to a storm sewer (this is most likely where it would end up if you have ever piped a sprinkler drain out an exterior wall). This is not OK everywhere, so for your specific project, it would be best to ask the AHJ and the plumber (and possibly the plumbing inspector) on the project if it is OK.
