RE: Turley Septic System - Recommendation of Final Approval
Frying Pan Road
ECEH Permit # OWTS- 4-11-5903
This Final approval letter is written for the septic system and the associated
permit that serves the Turley Home in the Frying Pan Valley. The system was
designed in 2011 and installed in the summer of 2011 and placed into service in
the summer of 201 MWE (Carter Page) inspected the installation of the system
and found it was installed according to MWE’s design with minor changes as
noted on the asbuilt drawings and ECEH requirements. This letter is to serve as
the acceptance letter for MWE and recommendation to Eagle County for final
acceptance of the system.
Attached is an asbuilt drawing of the system installation.
To my knowledge the system was installed according to MWE and ECEH
standards and the system layout was installed per the attached asbuilt design
drawing, which can be used as the asbuilt for system and permit. The system
consists of 1 - new 1250 gallon and 3 rows of infiltrator units (23 units in each
row) in a serial distribution system with 69 total units. All trenches were installed
using a infiltrator gravelless chamber system. All setback limitations were met.
Please call is you have any questions.

RE: Turley Residence - Septic System Design Notes – Frying Pan Road
Eagle County ISDS # to be determined
The following are my design notes for the new septic system to serve the new Turley
residence in the Frying Pan Valley. The site is the flat area to the west of the home.
- 4 - Bedrooms
- Approx. 4,000 Square Feet of living area
- 75 gallons per day per person
- Per Rates – 17 to 24 MPI, (use 22 avg mpi) – See Attached percolation test results by HP
Geotech
- Soils fractures sandy silty clay loam with small rocks – See attached HP GeoTech
Report as well
- LTAR = Loading rate of .65 gals/sq ft.
- Ground water 20+\- feet from surface not encountered
-The home is fed by a community well more than 500 feet away– no water lines in the
area of the field and system will meet any required setbacks from the well
- The Frying Pan River is approximately 100 to 150 feet away and the system will meet the
100 foot setback requirement
Flow = Q = 4 bed rooms x 2 peo/br x 75 gal/day/per x 1.50(max flow) = 900 gallons per
day.
Tank sizing - 4 - Bed Rooms requires 1,250 gallons of septic tanks; Q X 1.25 – Install
either a 1,250 or 1,500 gallon double chambered CONCRETE septic tank. Install tank to
meet site contours and allow access for cleaning, next to the proposed home. See tank
notes below.
McLaughlin Water Engineers. 111 P AABC, Aspen, Colorado 81611 P 970-925-1920 F970-925-1974
This is a gravity feed system using infiltrators and serial distribution. No pumping or
dosing system is proposed.
Area of Septic field required = A
A= Q/5 X SR of Perc Rate or 900/5 X SR 22 = 845 SF
Percolation Rate = 17 to 24 minute per inch Use 22 mpi for the average or
LTAR = Loading Rate of .65 gals per square foot. The 0.65 is a similar rate used in the
area for similar soils as reported in the HP Geotech Report
A=Q/LTAR
900/.65 = 1,385 square feet
Use LTAR sizing of 1,385 SF as it’s the larger required area
Design Proposes to use Infiltrator Quick 4 units or ADS ARC 36 Units. The State and
Eagle County allow a 50% reduction in area when using these systems
With the 50% reduction for ADS or Infiltrators – Number of units is as follows for each
ADS – ARC 36 5 feet long and 24.5 sf/unit = 57 units – Use 3 rows of 19 even length
trenches for 57 Total units in a 95’ long trench
Infiltrators= Std Quick 4 – 4 foot long and 10 sf/unit = 69 units – Use 3 rows of 23 units for
69 Total Units and a 92’ long trench
Install 3 rows of 19 or 23 units depending on product used, (see above), in a serial
distributed trench system of 57 or 69 total units. Contour the trenches to fit site
conditions and the topo of the site. Trenches are to be 10' apart, (6’ of undisturbed soils).
System size = 92 to 95' long X 26’ wide. Minimum depth = 12"; maximum depth = 24" to
top of infiltrator. Install ~ 3” of concrete sand at the bottom of the trench to level the
trench and units and to provide a better biomass surface. Install access port on the end
of each row of trenches. Locate access ports to minimize conflicts with site.
The new double chambered 1,250 or 1,500 gallon concrete tank shall be installed in the
general area west and below the home in the open area. A minimum drop of 3” is
required between tanks. Tees will be installed on both the influent and effluent lines of
the tank; set on the inside of the tank. Set top of line from tee within 1" of the roof of the
tank and extend line downward 14" below centerline of tee. Maximum cover over access
to tank shall be 6" and easily accessed for maintenance. Asbuilt location of the tank lids
for future maintenance. Tank lids normally are not to be buried, however if required,
minimize cover and landscaping on lids to allow yearly access. Bedding under and within
6" of the tanks will be roadbase compacted to 95%. Installation of native fill or screened
rock around the tanks outside the bedding zone is acceptable.
Fill tank with water prior to backfill to check for leaks and leave water in tank for placing
the system in service. Septic tank will be two-chambered tanks. Install an OSI 4" diameter
Biotube, or equal, inside the new tank’s effluent line. The housing is to be 36" high with a
McLaughlin Water Engineers. 111 P AABC, Aspen, Colorado 81611 P 970-925-1920 F970-925-1974
unit length of 28", using SDR 26 PVC piping.
Piping from the home to the tanks will be 4" SDR 35 PVC laid at a minimum of 1%.
Insulate lines with less than 42” of cover or in uninsulated crawl spaces. Minimum depth
is 3.5' for all piping. Install cleanout between house and septic tank. Use standard 2”
Blue Board insulation placed 6” above the pipe and laid on a flat bedding surface if less
then 3.5’ of cover on all pipelines to and from the septic tanks. Install cleanouts between
the home and septic tanks.
Distribution line to the field from the tank and in between the serial distribution system
shall be 4” SCH 80 PVC. All pipe bedding to consist of a minimum of 2" under and 6"
over the pipe of native soils with maximum sized material of 1”. Remove all burrs,
excess material, and other debris from edges of the pipe. Rake trench bottoms and
sidewalls prior to installation of infiltrators.
The 3 rows are to have serial distribution. Follow the manufacturers recommendations
for installation of the serial distribution pipe in and out of each row of infiltrators, where
the 4” solid Sch 80 PVC enters the row of infiltrators and stops at the first infiltrator. The
serial distribution continues at the end of the each row with solid 4” Sch 80 PVC to the
next row. Trenches to be with in 1" of level across the entire length of each row. Each
row may be stepped down to match contours and other site conditions. Install splash
plates under the entry and exit piping at each end of each row of infiltrators. (Splash
Plate - 1’ Wide and 18” Long)
Adjustments to fit site contours and conditions may be made per approval of the
engineer and homeowner. Minimize trees to be disturbed during installation. No tree
removal without consent from Owner. The engineer shall finalize elevations of the tank
and trenches in the field. Installation and operation shall be approved by the engineer
prior to final acceptance.
System must meet all Eagle County ISDS requirements and MWE design standards.
System is required to be installed by a Licensed Installer. Contact Eagle County for an
approved listing of Installers. Owner is recommended to pump the septic tank at 2-year
intervals. Landscaping and watering us on top of septic field shall be minimized or
eliminated.
MWE will provide inspection at the installation of the tank and piping, tank leak testing,
and installation of infiltrators and serial distribution. MWE is to be notified prior to each
required inspection.
Eagle County will require inspections on the tank and infiltrator installation. Please notify
Eagle County in advance of all anticipated inspections.
See attached ISDS Completeness form for more information on installation requirements
and information needed for asbuilts. The contractor or installer is responsible to supply
the Design Engineer and County with asbuilt information prior to final acceptance.
