Introduction
The Vail Valley Learning Camp is proposing to operate within the Ute Springs Subdivision. The
camp is an overnight camp which operates predominantly in the summer, approximately as
follows:
• June, July, August: full use: 50 students, 15 teachers
• Sept. -May: %4 use: 12 students, 3 teachers
A Lodge is proposed to be constructed on Lot 3 for the purposes of:
• Kitchen
• Bathhouse
• Laundry-
0 Bathroom
• Infirmary
Students are to sleep in 6 yurts to be placed on Lots, 1+2, with 2 Devap (Biological Mediation
System Composting) toilet systems located near the yurts for nighttime use (at one location, boys,
iris . Hand wash will be provided, with running water from the Lodge.
The Devap systems have successfully been in operation for a number of years at Vail, Beaver
Q Creek, Arrowhead, Telluride, Deer Valley and Copper Mountain ski areas. The Devap system is
an odorless, waterless, non -discharging system.
Composting toilets are proposed to reduce water consumption for the well permit, and provide for
horizontal setbacks to the existing well and meet setback requirements to the pond and stream.
(See sheets 7, 8)
The composting toilets require a small amount of water to operate, which is to be provided by a
water service line, which will also be used for handwashi. Due to the long distance from the
Lodge (where the water treatment exists), it will be very expensive to pipe treated water to the
restrooms.
The well water has over 250mg/l of sulphates: we are proposing to u e reverse osmosis treatment
for drinking water and run r/o water to the restroom. I",

be paper service. 2 standard water tank toilets are to be provided in the Lodge, for
infirmar teacher use only: it will either be locked, signed, or located in a bedroom to restrict
u ent use. A third devap system will be located in the Lodge for general use (see schematic
attached. .
The students will sleep in the yurts, and have their classes/sessions on the yurt decks during the
day: they will only go to the Lodge for mealtime. Most of the day will be spent at the yurts, on -
site, or off -site not at the Lodge.

•Soil Profile Hole
Two soil profile holes were available, apparently dug for utility construction to the North and
East of Lodge. Both profile holes were similar, if not the same: 3-4' deep of silty/sandy loam, 1'
deep layer of sandy gravelly silty loam, then 1 to 2' of silty sandy loam, over evaporite bedrock
One hole was 6.2' deep, the other 5.6' deep where an evaporite (possible gypsum) was
encountered. The evaporite was very hard, but appeared to percolate water (it is more likely
absorbing water) - and was considered an impervious layer. Since the infiltrators will be 1 %'
deep; there should be 4' of percolative material below the infiltrators/absorption area to the
evaporite - bedrock. (The evaporite reacts to acid, so it is likely a calciferous evaporite, and not
gypsum).
The soil appeared to be uniform across the proposed leach field area, except for some areas on the
west/upper side of lots 2 & 3. It appears that if a pump option is used, and a field placed above
the lodge, 1-2 infiltrator trenches may cut thru this other soil type. This soil did not have as much
vegetation growing on it, but appeared to have more roots in it, was hard to dig and slightly
cemented: it would break into pieces, that by hand could be pulverized into fine silt and sand. I
was concerned that the soil could be gypsiferous, and therefore ran a specific perc test within the
soil which was prewetted and tested for 1 3/4 hours (perc test #2). The hole actually percolated
faster than the other holes in the typical soil condition.
Percolation Tests
4 percolation tests were run in the area of the Lodge Lot 3 absorption area. Since there are at
least 2 options for leach field locations, it is recommended that the system be reviewed, adjusted,
and if necessary obtain perc tests in actual field areas, and/or verify soils and percolation during
the inspections of septic system construction.

Absorption Area
The slowest, last 10 minutes of the 4 percolation tests was 42 minutes/inch. The average of the
perc tests, last 20 minutes was (24+12+19)/3 = 18 min/in. For the application rate, the soil could
be classified as a "sandy loam, loam" or "Loam, porous silt loam", with application rates of
.6gpd/sf. and .45gpd/sf respectively: based upon percolation rates, the average of the last 20
minutes (18 min/in), indicates an application rate of .45gpd/sf., and the slowest last 10 minutes (42

WATERLESS TOILETS
WATER CONSERVATION TECHNOLOGY
FOR PUBLIC RESTROOM FACILITIES
Water is our most precious resource. Without it, we could not exist: We drink it, grow food with
it, recreate in it, use it for industry and flush it down the toilet.
Biological Mediation Systems is the leader in the development of systems designed to conserve water
and reduce energy costs. Our hands-on field experience, in connection with research and
development, has resulted in the creation of two patented systems, the DEVAPT" 2000 and the Vault
Evaporator.
Systems:
I. DEVAPTM 2000
The DEVAPTM 2000 is a zero discharge on -site waste reduction and treatment system. This system
can be used for any application where clean, odorless restrooms are needed. Since the DEVAPTM
2000 effectively reduces and treats waste on site, without a sub -surface drain field, the benefits are
numerous. (Please see Important Notice - attached)
Benefits:
1. Reduced energy cost savings, since pumping is not usually required
2. Safe for the environment, does not pollute underground water supplies
3. Unequaled performance which does not emulate any other technology
4. Odorless
5. Uses no chemicals
6 Ease of maintenance, maintenance personnel agree the Devap"m 2000 is the "system of
choice"
7. High public approval
8. Saves water
The DEVAPTM 2000 can be used, and is currently in use, in luxurious homes, guest lodges, ski
resorts, trails, camps, offices, highway rest areas, day use areas, parks, etc. Indeed, the DevapTM
2000 is suitable for any location where public restrooms are needed, as well as being ideal for back
country areas where on -site waste reduction is important. (For AC or DC application)
II. Vault Evaporator
The Vault Evaporator is zero discharge on -site waste reduction technology. This patented system
was developed to address two very important issues, odors and escalating pumping costs. The Vault

SYSTEM
THE DEVAP'" 2000 1S A HUMAN WASTE REDUCTION SYSTEM
THAT HAS A PRIMARY DESIGN FUNCTION OF ELIMINATING LIQUID.
The DEVAP' 2000 has been designed to achieve
an optimum -controlled environment for the
natural aerobic biological reduction of human
waste. This system is an odorless, waterless,
natural process that uses no chemicals. It has
been specifically designed for heavy public use
and can be installed in any location.
Our DEVAP" SYSTEM accelerates the process of
waste reduction through evaporation and
dehydration. This system controls the direction
of the air as it moves through the conversion
tank. This provides a clean and odorless
restroom facility. Another unique feature of the
DEVAP'" SYSTEM is the control of liquid. Liquid
that enters the tank may travel up to 126 feet
during the evaporation process. There are two
methods of directing liquid to the back of the
tank: one is to pipe the urinal drain to the rear of
the tank, and the other is through liquid channels
on the sides of the center vent that direct liquid
to the rear. This increases the liquid retention
time and allows thousands of cubic feet of air to
pass over the liquid in the bottom as it travels
and evaporates. The ventilation fan can regulate
the amount of CFM, depending on usage.
- . %% y' _'
The engineered ventilation system is desi ned to
regulate the amount*of oxygen (air) that frows
through the conversion tank. The amount of air
flow (or CFM) can be regulated, depending on the
amount of usage. The ventilation system directs the
air flow by pulling air into the tank, either through
the toilet chutes or air vents. This provides the
oxygen for the initial conversion area. Air is then
pulled down the two side panels to the lower
portion. This again provides the oxy&en for the
biological process and a continual air flow for
evaporation. The air flow is then directed into the
center clean -out vent to be exhausted out of the
tank.
The maintenance aspect is one of the most
important features in the DEVAP` 2000 final design.
The removal of the finished material is required at
least once a year. The front lower area of the tank
provides a clean -out area 18".vide and 60" long.
After the first year of use, material is moved into this
area from the interior bottom of the tank. Another
unique feature is the center vent and side vents
allowing the removal of material from the back,
center and front of the tank. The material that has
been moved into the removal area is allowed to
remain until it is thoroughly dry. The DEVAP'
SYSTEM prevents liquid from entering the clean -out
area. I .
Two interior service tools, an interior light and viewing ports, allow
maintenance personnel to service the upper chamber without opening
the access door or removing the service tools.11

Piney Run Park and Nature Center
30 Martz Rd.
Sykesville, Maryland 21784-8125
Dear Mr. Lustig
I am hanpv to reply to the questions in your letter of February 7, 1998 concerning our exner;erlce
with composting toilet buildings and the units from Biological Mediation Systems (BMS) in
particular. The Coconino National Forest has been installing composting toilets since 1989 and
currently operates 12 composting toilets at 10 different campground and day use recreation sites. All
but two of these sites are adjacent to streams and reservoirs. (Note: I will use the term
"composting" thoughout this letter to collectively refer to all of the various types of composting or
evaporative waste treatment units available.) We have composting units from four different
manufacturer's and have settled on the BMS units as our preferred choice. BMS has put a lot of
thought into their design. The units are easy to maintain and easily.accomodate shock loading from a
holiday weekend. We have received excellent support from BMS after installation. They call
whenever they plan to travel through our area to see if we need anything and usually stop by one of
the sites to monitor the operation of the unit.
In general, composting toilets have worked out well for us. Our visitors like the them for their
cleanliness and odor free environment compared to our standard vault toilets. Where we have a site
that is environmentally sensitive or has restricted access for a sewage pumper truck we prefer using a
composting toilet.
We currently have 3 BMS units in operation ranging from 4 years to 6 months old, all are working
fine. One of these units was a retrofit of an older composter that proved too small for the usage and
was replaced with a BMS unit. The utilization level of these units ranges from about 25% of
capacity'at a reservation -only equestrian campground to about 60% at a campground. We have 2
more toilets with BMS units under construction that will go into service this spring.
One of the existing and both of the 2 new BMS units are located at recreation sites along Oak Creek
near Sedona, A.Z. Oak Creek is one the few perennial streams in our area and the state legislature
has designated it a "unique waterway," meaning that any wastewater discharge within 1/4 mile of the
stream must be the same water quality as the creek or be fully contained in a lined disposal system.
The Arizona Department of Environmental Quality (ADEQ) regulates all of our wastewater
facilities. We follow their setback requirements of 100' to a live stream or lake, our closest toilet to
Oak Creek is about 120'. ADEQ also requires us to install some type of backup device to evaporate
or store any excess liquid that can't be evaporated by the composter at our sites along Oak Creek.
This is due to problems experienced by most of the earlier composting systems with evaporating all
of the liquid waste they received. We have been allowed to locate our toilet buildings just inside the
U�S IF' -
Caring for the Land and Serving People Prmed on Recyded Papef
100 year flood plain as long as the top of our evaporation bed is above the flood plain. These beds
look like raised planter beds with a decorative rock surface and they double as interpretive exhibits.
A small sign on the side of the bed explains that the composter and evaporation bed are part of a
self-contained wastewater treatment system that doesn't use any of the limited drinking water
available at the site. At first ADEQ wanted a chain link fence around the raised bed to keep people
off of the gravel surface. We asked them to allow us to try these signs instead and they have been
very effective at doing the same thing at much less cost and visual impact. We have received quite a
few favorable comments about the message we're conveying and it ties in with the conservation
message given throughout this particular site.
We chose to use a lined evaporation bed adjacent to each of these toilets that takes advantage of the
and climate at these sites to dispose of any excess liquid waste. At our toilets equipped with BMS
units the amount of excess liquid going to the evaporation bed has been minimal as observed through
an inspection port built into the bed. BMS sizes the ventilation system for each site's usage and v
relative humidity conditions. At one of our sites located away from Oak Creek we have equipped
the BMS unit with their DEVAP equipment to evaporate the excess liquid in place of a Ieach field.
This device has worked well. We have not been required to install these backup devices at sites away
from Oak Creek.
At most of our older composting toilets we constructed a small leach field when soil conditions
permitted. A small pump inside the composter operated by a float switch pumps the excess liquid to
the leach field. The leach field was located 200-300' from any watercourse The typical volume of
excess liquid is usually less than 5 gallons per day, about 10 gal/day on a holiday weekend. Another
site with an older composting toilet is built on solid rock next to a boat ramp at a remote reservoir.
The composter is connected to a 200 gallon fiberglass tank in the basement to collect the excess
liquid. The tank is periodically pumped out by a septage hauler but we have been thinking of fitting
the tank with fan and air diffuser to help evaporate the liquid and maybe eliminate the need to pump
it out.
We would not hesitate to use BMS for any future installations. Their designs, service, and quality of
materials have been the best of the four manufacturer's I have dealt with. They are a very innovative
company when it comes to restrooms at difficult or sensitive sites. ADEQ has been quite pleased to
see us use composting toilets instead of vault or flush toilets because the waste is treated onsite
instead of carried elsewhere or put into the soil for disposal. ADEQ intends to use one of our sites
on Oak Creek that will be finished this spring as a demonstration site to show nearby landowners
what can be accomplished with composting and photovoltaic technology.
I hope this information will be of help in allowing your new facility to be built. In my experience, a
BMS toilet located within 60' of the reservoir would not be a potential pollution source if properly
maintained and located above the maximum spillway flood elevation. In the unfortunate event a
composting toilet should be inundated by flood and any waste escapes the unit, the dilution factor is
so great as to make it imperceptible, probably no worse than the amount of wildlife excrement that
would be washed into the reservoir. Our only experience with leaking composters has been on our
older units that depend on effluent pumps to transfer the excess liquid to a leach field or holding
tank. Occaissionally the pumps have failed or plugged up with fine sawdust. The liquid level would
build up and eventually flow out a vent hole in the chamber and make a puddle on the floor. Clean
up was done with a mop, bucket and disinfectant. We have not had this problem with any of our
BMS units. Composters have the advantage of being able to readily detect any problems because all
of the equipment is exposed and easily inspected whenever the routine maintenance is done. Any
leak would be readily noticed and contained in the basement, unlike a buried vault or sewer line.
Should you desire any additional information or need to clarify any of the above, please feel free to
contact meat 520/527-3591. If you ever happen to be in the vicinity of the Grand Canyon, we are
about 80 miles south and would be happy to show you any of our sites.

Shannon Clark, P.E.
