RE: Buffalo Valley Force Main Calculations
Dear Larry and Robin:
Please find enclosed calculations for the Buffalo Valley Low Pressure Sewer System.
I am enclosing calculations which size the force main and pumping requirements for
Buffalo Valley. I am attaching a sample pump curve for the Buffalo Valley duplex
pumps. Finally, I am attaching some sample specifications and pump sizes for
residential uses that can be used as a guide. Myers Pumps, the pioneer of low
pressure sewer systems, will be sending me a software program that can be used for
sizing future pumps and service mains. As soon as I receive that I will go through
their methodology and provide that information to you. I can also provide a copy of
their software.
If we can provide any additional information, please contact me.
Sincerely,

RE: Application For Site Approval For Construction of Lift Station
Buffalo Valley Inn
Dear Larry and Mark:
Please find attached hereto the above -referenced application. This application is for the lift
station and associated force main being constructed in conjunction with the remodel of the
Buffalo Valley Inn owned by Mr. Kurt Wigger. The Colorado Department of Health requires
such an application for all lift station project for which they have jurisdiction. By way of
review, there were three alternatives considered for wastewater alternatives for the subject
property:
Modification and repair of the existing septic tank system.
Construction of a lift station and pumping of the wastewater for treatment at the
El Racho Mobile Home Park.
Construction of a lift station and force main for connection to the City of
Glenwood Springs wastewater collection system and treatment facility.
The latter alternative was chosen and is the subject of this application. The alternative provides
for the elimination of a commercial septic tank installation. While the lift station will service
only the Buffalo Valley Inn, the force main has been sized to accommodate future use by the
intervening residential properties along County Road 154, including Mountain View Baptist
Church, El Racho Mobile Home Park, Holy Cross Electric Association office complex,
commercial properties east of Hwy 82 and single family residential properties from Buffalo
Valley to Glenwood Springs. These properties are not part of this application and are not being
connected to the City of Glenwood Springs wastewater collection system at this point in time.
Construction of the facilities under this application, however, will allow these properties to be
connected upon meeting the requirements of the City of Glenwood Springs.
Wastewater flow from the Buffalo Valley Inn has been calculated based on the following criteria:
240 seating capacity @ 10 gpd = 2,400 gpd
May 20, 1993
Messrs. Thompson and Bean
Page 2
15 employees (g? 15 gpd = 225 gpd
Total 2,625 gpd
The peak day wastewater flow as been estimated at 1.5 times the average daily flow, or 3937.5
gpd. The average day wastewater flow and peak day wastewater flow represent the hydraulic
loading impacts to the City of Glenwood Springs wastewater treatment facility. The lift station
is being sized to maintain minimum flow velocities in the force main system. The lift station
will be a duplex pump arrangement with each pump rated at a capacity of 50 gpm. I am
attaching calculations with this Permit.
Please note that the Site Application requires a sign -off by the City of Glenwood Springs as the
"Local Government". The City Council has previously approved the project. Sign -off from
Garfield County is required at two locations, on the blank for "Board of County Commissioners"
and for "County Planning Authority", since this project does lie within the County - not the City
boundaries. In previous conversations with Mark, Garfield County is no longer providing sign -
offs on Site Applications as the local health authority.
Please feel free to contact Mr. Dwain Watson, Colorado Department of Health, Grand Junction,
directly with any questions either concerning the contents of this Site Application or the
procedures to be used for its approval. As you know, Dwain has been directly involved in the
discussions of alternatives and implementation of this project. I would like to schedule this
application on the agenda of the Planning and Zoning Commission and Board of County
Commissioners as quickly as possible.
Thank you in advance for your continued cooperation on providing a solution for the wastewater
needs of the Buffalo Valley Inn. Please call me with any questions.

Wastewater Applications
The Myers versatile 2 horsepower WGL-20
submersible centrifugal grinder pumps
wastewater at capacities up to 40 gallons
per minute and heads up to 105 feet. It
features Myers' patented cutter mechanism
and recessed impeller design to effectively
mascerate typical sewage solids into a fine slurry.
The slurry or wastewater can then be pumped
to a treatment plant, lagoon, or gravity man-
hole through a discharge pipe as small as
1'/4 " in diameter.
The Myers WGL-20 can be installed with a
variety of package systems. A simplex or
duplex, quick -disconnect fiberglass rail system
can be used for depths up to 16 feet. In areas
with mild climates and shallow frost lines, the
grinder pump can be mounted on legs for Union
system installation. A suspended type package
system is also available for indoor applications.
The WGL-20 grinder pump is not
recommended for heavy duty applications.
Instead, use a Myers 3, 5 or 7-1/2 horsepower
grinder pump.
F.E. Myers manufactures a complete line of
sump, sewage, effluent, grinder and non -clog
submersible wastewater pumps. Myers
also manufacturers a companion line of
control panels, controls, and fiberglass basins.
