    • DHSS or a local agency, typically the county health department, is responsible for an individual subsurface septic system serving one single-family residence, an individual lagoon serving no more than one single-family residence, and specified cluster or centralized subsurface systems with maximum domestic flows of 3,000 gpd or less.
    • The official state source does not identify which local agency, if any, administers the applicable DHSS/local-agency category specifically within Eugene Township.

    local-agency cluster or centralized-system maximum daily flow: <= 3000 gpd (Applies to cluster or centralized systems with subsurface soil dispersal under the same common promotional plan within the same operating location.)
