The St. Benedict Monastery Cabins E and F septic systems has been installed by
Bill Doray Excavation and placed into service. MWS and GDD have inspected the
installation of the systems and find both were installed according to MVWE's
design and PCEH requirements. This letter is to serve as the acceptance
letter for MWH and recommendation to Pitkin County for final acceptance of the
system. I have attached a not of record drawings for your information and

Benedicts Monatetery Cabins E and F - ADDITIONAL NOTHS111
Design change:
This change will apply to both of the new systems being installed at the
Monastery for cabins E and F.
Due to field conditions limiting the area available for use, we are changing
the design of the field from 4 trenches with 7 infiltrator unite in each
trench, (28 total), to a bed system with 40 total units. The bed will be
approximately 5 units wide and 8 units long, or 15, wide and 48, feet long.
A minimum of 38 units is required for the system due to the fact that no
reduction in sizing allowed for bed systems. 40 units are being used in this
design to allow to even lengths in the bed system. See original design notes
for more information regarding the design.
This will be a field change and a asbuilt of the new design and layout will be
provide after ;Final completion, acceptance, and approval.

From: Dean Derosier; McLaughlin Water Engineers, Ltd.
RE: St. Benedict's Monastery Cabins - Septic System Design Notes - St.
Benedicts Monastery Cabins E and F
The following are my design notes for the new Cabin's E and F Septic System
design. The site is a sloped area on above the valley. This design applies to
each cabin, thus each cabin will have a similar system installed to provide
septic service.
- 1 - Bedrooms (Design 2 min)
- Approx. less than 2,000 Square Feet of living area, Remote cabin
- 75 gallons per day per person
- 30 minutes per inch perc rates - Perc Test by GDD/MWE
- Ground water 150+\- feet from surface unknown not encountered.
- Well for domestic water - 100' min away and above system
Flow = Q = 2 bed rooms x 2 peo/br x 75 gal/day/per x 1.75 = 525 gallons per
day.
This requires the new system to be 100 -feet from the well.
Tank sizing - 2 - Bed Rooms requires 656 gallons of septic tanks; Q X 1.25
Install one 750 gallon tank for the cabin. If a plastic tank is used, proper
bedding must be used to protect the tank.
Area of Septic field required = A
A = (Q\5) x square roots of the perc rate (AVG) = 525/5 X SR(30)
A = 575 square feet = 38 Infiltrators
30% Reduction with Infiltrators
Ar= 403 Square Feet =126 Infiltrators
System size is for 28 infiltrators to allow for even length rows in a trench
system, with trenches 10 apart minimum. (4 rows OF 7 UNITS or 28 total UNITS)
The layout of the system is to fit site conditions and meet all setbacks as
shown on the attached drawing. Maximum size of bedding material over top of
infiltrators is 211. Min cover over units is 18" and approximate dimensions
are 30' X 421.
The Tank will be installed in the general area below the home. Tees will be
installed on both the inffluent 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 1211 below center line of tee. Fill tank with
water prior to backfill to check for leaks and leave water in tank for placing
the system in service. Septic tanks will be a two -chambered tanks with access
ports within 6" of final grade.
Piping from the cabin to the tanks will be 4" SDR 35 PVC laid at a minimum of
1%. Insulate lines with less than 5 -foot of cover or in uninsulated crawl
spaces. All piping to be bedded in a minimum of 2" under and 6" over of 3/4"
screened rock. Piping from tanks to field shall be 4" SDR 35 PVC with a min
slope of 1%. Provide a 4" distribution line to each trench. Install tees to
distribute flow to each trench of infiltrators. Install vents at the end of
each row or trench.
Adjustments to fit site contours and conditions may be made per approval of
the engineer. Elevations of the tank and trenches shall be finalized in the
field by the engineer. Installation and operation shall be approved by the
engineers prior to final acceptance. System must meet all PCEH and MWE
standards.
