The "System" names have been updated to reflect changes/additions related to the Third Amendment to Consent Judgment (effective March 8, 2011). The former "Western System" has been renamed "Little Lake Area System". Two new systems will replace the previous system nomenclature: "Western Area System" (west of Wagner Road) and "Eastern Area System" (east of Wagner Road).
