What kinds of water systems operate in Lake County?

Lake County's active systems break down as 3 community systems (3.2%), 2 non-transient non-community systems (2.1%) and 89 transient non-community systems (95%). A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. EPA lists their owner types as private (81%), state government (9.6%), federal government (6.4%) and local government (3.2%).
