You can find it easily from multiple sources if you bother to look. You can start with Wikipedia.Basically, 80% of the annual water use in California is agricultural irrigation. That leaves 20% for residential use. Of that, more than half goes to landscape watering, a good chunk of that to golf course in the Palm Springs area, and I think you will agree that illegal aliens don't typically have lush lawns. So about 8% goes to actual household use--toilets, showers, etc., with usage heavier in more affluent neighborhoods. Illegal aliens make up about 10% of the population. So, assuming that illegal aliens use the average amount of water, they account for less than 1% of the annual water used in the state.
