ROCKER WATER AND SEWER DISTRICT is one of 123 community water systems in Montana in the 501 to 3,300 people size category, formerly serving 2,250 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 5 entries between 1992 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.
