RELIABLE WATER SERVICE is one of 1,084 community water systems in Montana in the 500 or fewer people size category, formerly serving 110 people from surface water.
EPA's federal records list this system as inactive in 2022; the record below is historical.
As of August 1, 2026, its federal record holds 13 entries between 1998 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.
Of the 13, 8 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 the Lead and Copper Rule, the Consumer Confidence Rule, and the Total Coliform Rules.
