Silver Thread Public Health District (STPHD) OWTS Rules & Regulations

OWTS Permit Application

Individual On-site Wastewater Treatment Systems are regulated by Regulation 43 in the State of Colorado.  Please contact the Mineral County Land Use Office at 719-658-2360 for any question regarding an OWTS.  OWTS Systems are now designed based on the soil content of that property.  The percolation test is not a valid test for designing an OWTS.  Per Regulation 43, a system in Colorado has to be designed by a "competent technician" or a licensed Professional Engineer from the State of Colorado, depending of the soil type.
