Installation Observations
Westcliffe Project
1025 Star Mesa Drive
Pitkin County, Colorado
Richard,
ALL SERVICE septic, LLC performed installation observations for the onsite wastewater treatment
system (OWTS) on May 4th, July 19th, August 9th, and October 18th 2011 for the subject property.
On May 4th a site visit was conducted to evaluate the existing drain fields and implications of the
existing liners. A letter was provided.
On July 191h we observed the septic tanks, and requested a filter handle. We requested the primary
outlet tee be raised, and a change in the 90 deg fitting in the Flow Splitter Basin.
On August 91h we observed prior requests completed. The installation included a 2500 gallon single
compartment septic tank, followed by a 2000 gallon single compartment septic tank with an effluent
filter, followed by a 500 gallon septic tank with a dosing siphon. The drain field consisted of 10
gravelless chamber trenches with a total of 198 Q-4 chambers, equaling an area of 1955 SF. A flow
splitter basin serves effluent to the drain field.
The OWTS was generally installed according to specifications. This observation is not a guarantee of
workmanship and/or parts and materials. ALL SERVICE septic, LLC should be notified if changes
are made to the OWTS.
LIMITS:
The observation was based on information submitted and our site visit. If conditions are different
from conditions described in this letter, ALL SERVICE septic, LLC should be notified. All additional
OWTS construction must be according to the county regulations. The installer should have
documented and demonstrated knowledge of the requirements and regulations of the county in which
they are working.

Richard,
During our site visit on May 5th 2011 we observed the digging of one test hole on the
outskirts of the existing drain field.
The west `lined' drain field was full of water.
I understand it is the owners preference to move the proposed drain field trenches to the
west and not interact with the existing drain fields. If there is no interaction with the existing
drain fields, and the proposed trenches are not within 20 feet of existing lined ETA beds, the
ETA beds do not have to be altered. They can remain in place and be `abandoned'

Greg,
Please Drill a 3/16 -inch hole on the bottom side of the elbow in the Flow Splitter Basin per my request, and our
discussion. This will complete our septic construction and I will write letters to county for final approval.
CARLA - The elbow in the flow splitter basin has no room to turn or twist... therefore I am requesting weep hole
in elbow. This will allow for energy reducer device, and prevent freezing due to draining.

Just a reminder we agreed upon drilling a 3/16 hole in the elbow of the inlet pipe where it turns up, the distance from
the bottom of the pipe tolthe floor of the tank is only 1", this will serve as a drain for the pipe. Thank you for your help
on this and am looking forward to your e-mail blessing this procedure.

Subject: RE: Westcliffe Project
G reg,
Yes, I am happy. I have a couple of notes from the inspection that I did with Tim. One was that the pipe coming into the
flow splitter basin angles up. Tim and I thought that could cause a freezing issue and it would be better to angle it
down. Tim was going to Check on the final grading. Also, we'll need confirmation that the dosing siphon is hooked up
and primed prior to CO. It might be too early to think about doing that yet, but once you are getting ready to put the
system on line you can finish the installation and I will finalize the paperwork. Thanks,

on all sides of the new drain field. Just dig down and tear liner in multiple spots (every 12 feet or so)
to prevent a bathtub effect..

The existing drain field is an ETA bed with a liner. Therefore we really need to remove the liner under
the areas of the new drain field only. I have seen the liners pulled up before and they come out
relatively easily. I am less concerned with the gravel and or sand that is in the field being removed,
that would not hinder the proposed new system. Just the liner and fabric should be pulled out, under
the new field area only

Larry,
Yes, if the soils appear to be saturated, I would say the Tim will need to come in and make a determination if soil
replacement needs to occur. I know that puts a variable in your bidding process, which is never ideal. Hard to say what
we'll see until you get in there. Tim, can you comment on the remaining field area liner? Should we try to perforate
that as part of the abandonment process? I hate to see that liner intact still creating the bathtub effect and relying
solely on evaporation.

If I could comment i would say, no need to bring in any soil UNLESS the soil is totally saturated and
full of Biomat. then yes, bring in granular material, and place in 1 foot lifts, then bucket pack for

Larry,
That's a really good question that I don't think was adequately addressed either in the design or the permit. But I did
think about it! The existing field is a lined (10 mil PVC) ET bed with pipe and gravel covered with a mirifi fabric (or 4"
straw over the distribution piping). It might be feasible to perforate the liner rather than digging it up. It looks like the
system is 2-6" of topsoil, 7" of sand, fabric, 13" of rock, and the liner under that, so about 2' deep. Of course any portion
of the new field that overlaps the old will need to be entirely removed, but I don't know if there would be any harm in
leaving the rest of the system in place and providing a mechanism for water to get through it. We don't want additional
water to be diverted toward the new system. Tim, what do you think???

Carla & Tim,
1025 Star Mesa septic plans call for "Existing Drain Field to be removed" liner under proposed trenches must be removed.
Please clarify the extent of removal of "Existing Drain Field" Are we talking removal all chambers, piping and liner as well
as the soils underneath the existing trenches or do you have something else in mind? I've attached Tim's plans for your
review.
Let me know your thoughts.

will be allowed to pull our building permit for the work proposed inside the approved building envelope with the
condition that the owners will have their amended Land Use Approvals in place before the C of O is issued. We will
submit a OWTS waiver at the time of our permit submittal and I will talk to Carla at Environmental Health to see how to
proceed with her review.
Thanks again and have a great weekend!

Project No. 1739
Subsurface Investigation and Revised Upgrade Wastewater Treatment System Design
Westcliffe Project
1325 Star Mesa Drive
Pitkin County, Colorado
Ryan,
ALL SERVICE septic, LLC performed a subsurface investigation and an onsite wastewater treatment
system (OWTS) design for the subject residence. The property is located outside of Aspen, in an area
where OWTS and wells are necessary. The revision is based on a tank and drain field sizing
clarification.
SITE CONDITIONS
A single-family residence presently exists and is utilizing an OWTS, The current drain field will have
to be abandoned, and the liners partially removed due to existing trees. An 11 -bedroom residence
having over 6000 SF is planned. Remodeling will take place. The proposed drain field area slopes 8%
to the west, and vegetation consists of a moderate cover of grasses with sparse trees. The property is
served by a well located 300+ feet to the southwest of the residence.
SUBSURFACE
The subsurface was investigated by drilling one profile hole and 3 percolation holes, as indicated. The
materials encountered in the profile hole consisted of 1.5 feet of sandy clay topsoil, underlain by sandy
clay with scattered rocks to the maximum depth explored of 8 feet. Groundwater or bedrock was not
encountered. Three percolation holes were dug, in the area of the proposed drain field, as indicated.
Percolation rates ranged from 10 to 20 minutes per inch (MPI). A 17 MPI rate will be used to design
the OWTS.

Page 2
DESIGN SPECIFICATIONS
The OWTS design is based on 11 -bedrooms and an average sewage load of 2200 GPD. The
installation must include a 2500 -gallon, single -compartment, precast concrete septic tank, to be
followed by a 2000 -gallon, single compartment concrete septic tank with an effluent filter, followed
by a 500 gallon septic tank with a dosing siphon. (Front Range Precast out of Boulder 303-442-3207
can supply large tank). Tank alternatives may be considered. Ten gravelless chamber trenches, using
" `Quick -4' InfiltratorTM chambers, must be installed as indicated. There must be a total of 198
chambers and 1955 SF of infiltrative area. A flow splitter basin must be installed to distribute
effluent.
Construction must be according to the Pitkin County Environmental Health and Natural Resources
Department OWTS regulations, the OWTS Construction Permit provided by Pitkin County
Environmental Health and Natural Resources Department, and this design.
OPERATION INFORMATION AND MAINTENANCE
The surface of the drain field should be seeded upon completion. Vegetation is an important factor in
drain field performance. Erosion control should be practiced prior to and during re -vegetation. Geo -
fabrics or plastics should not be used over the drain field. No heavy equipment, machinery, or
materials should be placed on backfilled drain field. Livestock should not graze on the drain field.
Plumbing fixtures should be checked to ensure that no additional water is being discharged to OWTS.
For Example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day and
harm a drain field.
The homeowner should pump the septic tank every two years and clean the effluent filter as needed.
Garbage disposal use should be minimized, and non -biodegradable materials should not be placed
into the OWTS. Grease should not be placed in household drains. Loading from a water softener
should not be discharged into the OWTS. No hazardous wastes should be directed into the OWTS.
Mechanical room drains should not discharge into the OWS. The OWTS is engineered for domestic
waste only.
ADDITIONAL CONSTRUCTION NOTES
If design includes a pump, air release valves and weep holes should be installed to allow pump lines
to drain to minimize risk of freezing. Excavation equipment must not drive in excavation of drain
field due to the potential to compact soil. Extensions should be placed on all septic tank components
to allow access to them from existing grade. Precast concrete tanks and distribution boxes should be
used, unless plastic or fiberglass is required. Access to all tank compartments and distribution devices
is optimal.
INSTALLATION OBSERVATIONS
ALL SERVICE septic, LLC, and the county must view the OWTS during construction. The OWTS
observation should be performed before backfill, after placement of chambers and distribution pipes.
Septic tanks, distribution devices, pumps, dosing siphons, and other plumbing, as applicable, must
also be observed. ALL SERVICE septic, LLC should be notified 48 hours in advance to observe the
installation.

The design is based on information submitted. If soil conditions encountered are different from
conditions described in report, ALL SERVICE septic, LLC should be notified. All OWS construction
must be according to the county regulations. Requirements not specified in this report must follow
county regulations. The installer should have documented and demonstrated knowledge of the
requirements and regulations of the county in which they are working.
Please call with questions.
Sincerely,
ALL SERVICE septic, LLC
