  • Who permits septicMixed (with conditions)

    Onsite wastewater (septic) systems on land inside Otis town limits. Northeast Colorado Health Department (NCHD) issues OWTS permits; where the town provides public sewer, the town or its service provider decides whether sewer is feasible.

    • Under the NCHD regulations, no OWTS permit may be issued inside a municipality that provides public sewer service, unless sewer service is not feasible in the municipality's determination or the municipality otherwise authorizes the permit.
    • The regulations apply to all OWTS over municipal corporations in Washington County as well as unincorporated areas.
    • Regulations cited are the 2026 NCHD OWTS regulations; the NCHD OWTS page states that revised OWTS regulations are effective 6/15/2026.
    “no owts permit shall be issued to any person when the subject property is located within a municipality or special district that provides public sewer service, except where such sewer service to the property is not feasible in the determination of the municipality or special district, or the permit is otherwise authorized by the municipality or special district.”

    • Denials may be appealed to the local board of health within 60 days, per a secondary source; not verified on an official page.
