Check your bill. The City of Surprise runs the Mountain Vista, Desert Oasis, Surprise Foothills and Circle City systems. EPCOR and El Mirage serve other parts of town, and some small systems report through the Arizona Corporation Commission.

No. EPCOR's 2025 Agua Fria report says it doesn't treat drinking water for hardness, which ranged from 2 to 17 gpg in that district.
