Stewart Residence, 13 Silver Spruce Dr., Carbondale CO, 81623.
OWTS Construction Approval Letter. (Project No. 2151609)
The proposed OWTS field design at 13 Silver Spruce Drive outside of Carbondale, CO has been
installed per the approved plans through Garfield County.
The OWTS field was constructed of 3 rows of 14 chambers and a 4th row of 15 chambers to
accommodate 684SF of infiltration area. The design packet required a bed area of 675 SF per
the design. The 3 feet of sand required per this type of native soils was placed below the
chambers per design and the proposed bottom of chamber elevation was met to accommodate the
separation of chambers to ground water.
The septic tank that was constructed and placed by Valley Precast out of Bueno Vista, CO is a
1,500 gallon tank per the design calculations. The tank is fitted with a pump to pressure dose the
field as required with sand beds in the new state 43 regulations.
Please let me know if you have questions pertaining to this design letter submittal.
Thanks,
Matthew Langhorst, P .E.
