Population served: 120
Service connections: 70

PELICAN PLAZA is one of 583 community water systems in South Dakota in the 500 or fewer people size category, formerly serving 120 people from groundwater.

EPA's federal records list this system as inactive in 2025; the record below is historical.

As of August 1, 2026, its federal record holds 34 entries between 1976 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.

Of the 34, 23 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves synthetic organic chemicals, the Total Coliform Rules, and the Consumer Confidence Rule.
