Jynxie, did you find the answer to your septic question? we are getting a property in Cochise county and we wondering all the same things.
all i could find that there's a 1000 gal tank requirement or alternative system with a small septic. there's a requirement to get Soil and Site Evaluator to prepare the septic plan
application.
