We have been working with Mr. Andres to establish a suitable site for
the installation of the Biocycle unit under the innovative systems
program which has been encouraged by the Dept. of Health and Human
Services (DHHS). The site which we have selected required waivers to
the horizontal separation distance to an existing approved Class "A"
well. Attached is a letter from Kevin Kleweno at the Anchorage
District office/ D.E.C. dated August 19, 1994. This l~tter grants the
necessary waivers for the installation of this system on the
referenced property and for the utilization of a portion of the
existing absorption area for the final effluent discharge.
Also attached for your information is a property owners agreement for
the Biocycle wastewater treatment system. This agreement is dated
August 5, 1994 and is made b~tween the Muncipality of Anchorage
D.H.H.S. and the property owners. The agreement has also been
expanded to include a reimbursement to Biocycle PTY.Ltd. for the
Biocycle treatment unit if it proves to be successful.
Request you issue a permit for the installation and modifications of
the on-site wastewater disposal system on the referenced property. We
do not anticipate that the installation of this system will have any
adverse effect on any surrounding property. ~//~× ::

ADEC Project Number 9521-W/W-229-054, Review
Dear Mr. Shafer:
I have reviewed your August 17, 1994 submittal, the information provided to this office on
the Biocycle On-site Wastewater Treatment System, and the information in this office's
files regarding the original waiver. Based on this review, I have the following comments.
From the submitted information, the effluent that will be discharged into the existing soil
absorption system will be treated to a higher level than is currently being done by the
existing wastewater disposal system. In fact, it appears that you are resolving several
existing problems regarding vertical separation distances between the groundwater and
the lowest part of the seepage pit. With the general improvement being made in regards
to separation distances and with a higher treated wastewater being discharged, your
waiver requests are justifiable. Therefore, in accordance with the provisions of 18 AAC
80.030 Drinking Water Regulations, the following waivers are granted:
1. From Class A Public Water System Source Well
To Biocycle Treatment Unit from 200 feet to 135 feet
- To closest point of existing soil absorption system from 200 feet to 122 feet
2. From the lowest part of existing soil absorption system and the highest
groundwater elevation from four feet to two feet
These waivers will remain valid, as long as the following requirements are addressed.
1. Verification that all soil absorption systems not being used to accept

Copies of all analytical results from the required monitoring program on the
effluent from the Biocycle system will need to be provided to this office.
One sample of the inffleunt will need to be taken during the 12 month
testing period and analyzed for the same parameters as the effluent.
This waiver does not imply the granting of any additional authorizations, nor obligate any
state, federal, or local regulatory body to grant required authorizations.
Thank you for your coordination and cooperation with this Department. If you have any
questions, please do not hesitate to contact me.

2.1 DESCRIPTION
This Certificate relates to the Biocycle Waste Water
Treatment System, comprising a four stage process,
contained in a 2.28 m outer diameter outer tank and a
0.95 m diameter inner tank, each subdivided into two
sections giving four chambers. (See Fig. 1). The waste
water flows by gravity through each chamber in
succession. The function of each stage is described
below.
1) Reception and primary treatment (Chamber A)
Settlement of solids resulting in about 20-30%
BOD~ load reduction occurs in Chamber A.
Inorganic materials such as grit and sand will also
be removed by settlement. Floatable substances
· such as fat and grease may be retained and any
floatables that arise in the clarification stage (see
2.1 (3)) will be returned to this chamber. Substantial
reduction in the volume of settled sludge occurs by
anaerobic digestion and this is assisted by adding
some of the activated sludge from the next
(aeration) stage of the treatment process. It is
normal for a thick crust or scum to form on the
surface of the chamber.
2) Aeration (Chamber B)
The discharge from Chamber A flows by gravity to
Chamber B where the organic content is almost
totally degraded by a culture of bacteria referred to
as activated sludge. Oxygen, to support the
degradation processes, is introduced by a small air
pump and the bacteria are supported on a purpose
designed submerged plastic medium.
3) Clarification (Chamber C)
The discharge from the aeration stage drains to the
clarification stage (Chamber C), where separation
· by settlement of the biological solids, generated in
'the previous stage, occurs. The settled solids are
mainly returned to the primary treatment stage
(Chamber A).
4) Pump (Chamber D)
The clarified waste water drains to the sump and
from there it is pumped to the disposal location.
Disinfection of clarified waste water is available as
an option.
5) Safety Alarms
Within the Biocycle Waste Water Treatment System
three alarms are installed as warning devices. An
Part D - Materials and Workmanship
Biocycle waste water treatment tanks are made
of acceptable materials as indicated in Part 4 of
this Certificate.
alarm plate (audio/visual), is supplied to be installed
within the house. The alarm plate is similar to an
ordinary light switch with two coloured lights. A switch
provides for the alarm to sound and to be switched to
the "mute" position when heard. The alarm panel is
incorporated into an E.L.C.B. unit which is designed as
an extra safeguard in the event of an electrical fault.
The two lights indicate
(i) The high WATER level alarm - designed to sound if
the water level in the irrigation/disinfectant chamber
reaches a certain level. This indicates that the
submersible pump is malfunctioning.
(ii) The AIR pressure alarm - designed to sound if the
blower ceases to operate, or if the diaphragm ruptures.
(iii) The POWER supply alarm will activate in the event
of a power failure to the system.
The house holder is required to contact the company
when this occurs and Biocycle Limited is obliged to
respond within 48 hours.
2.2 MANUFACTURE
The outer tank, tank riser section and lid are designed
and constructed from steel fibre reinforced concrete in
accordance with the requirements of AS 1546 - 1990
'Australian Standard for Small Septic Tanks; The inner
tank and manhole cover are designed and constructed
from glass reinforced polyester in accordance with BS
4994:1987 Specification for design and construction of
vessels and tanks in reinforced plastics. Each system
design is assembled and fitted at the manufacturer's
works with the air diffuser system, pump, plastic
support media, system internals and pipework. Treated
waste water disposal (irrigation) pipework and electrical
connections are completed on-site.
2.3 DELIVERY, STORAGE AND MARKING
The tanks are completed ready for delivery at the
manufacturer's works. Off-loading must be carefully
supervised using chains, steel cables or lifting bars
rated in excess of five tonnes and should conform with
the requirements of the Safety in Industry Act 1980.
The manufacturer's instructions must be followed to
avoid damage to the tanks during off-loading and
placing in the excavation. A crane or other suitable
lifting equipment must be employed.
The tanks are supplied with full installation instructions
and are labelled on the outside to indicate the lAB
identification Mark incorporating the number of this
Certificate.
2.4 INSTALLATION PROCEDURE
2.4.1 General
The Biocycle Waste Water Treatment System must be
installed in accordance with-~he manufacturers
instructions.
The excavation must be of sufficient depth and width to
allow for safe and easy emplacement of the tank.
Generally a hole of 3 m x 3 m is satisfactory and the
depth will be largely determined by the invert level of
the drain from the premises to be served by the
Biocycle Waste Water Treatment System. The bottom
of the excavation should be dry and level, with no sharp
rocks or large stones protruding. In the case of soft or
unstable soils it may be necessary to put in Place a
levelled layer of compacted hardcore (about'200 mm)
or a concrete pad (about 150 mm thick).
Care must be taken to ensure that the tank is truly
vertical when it is lowered on to the bottom of the
excavation. If it is not, it must be raised and the bottom
of the excavation relevelled until it is absolutely level.
The tank' inlet port must be in line with the drain from
the premises being served.
The excavation should be backfilled to the inlet invert
level with materials such as sand or gravel. Materials
from the excavation may be used provided rocks and
large stones are excluded. Builders rubble should not
be used. The backfill should be carefully consolidated
around the tank. At all stages of installation, care
should be taken to avoid accidental entry of foreign
matter, (clay, stones, rubble, scrap), into the tank
interior. Except when work is taking place in the interior,
the cover should be kept in place at all times.
The lifting holes must be sealed with the plugs provided
and the surfaces sealed with epoxy resin.
2.4.2 Location
The Biocycle Waste Water Treatment System tank
should not be located closer than 1.5 times the depth to
the bottom of the tank or 3 m (whichever is greater) to
any building, road or wall so as to avoid damage to
foundations during excavation for the tank. It should be
located so that there is access for maintenance and for
desludging by vacuum tanker.
The tank should not be located in any area where
vehicles could traverse or damage it.
2.4.3 Treated Waste Water Disposal
Treated waste water may be disposed of by any of the
following means (See Fig. 1):
a) Surface Irrigation -- disposal assisted by
evaporation and vegetation.
or
b) Subsurface Irrigation -- disposal assisted by
evapotranspiration and vegetation, (direct root feeder
system, or subsurface disposal field).
or
c)
Discharge to surface water in a ditch or drain. A
licence to discharge to waters will be required
from the local authority to comply with the Water
Pollution Acts (1977-i990), if this option is
selected.
The extent of the disposal or irrigation area will be
determined by the population served and the soil
percolation value at the site in accordance with the
guidelines given in Table 1. For each site a test shall
be carried out in accordance with the Biocycle
Irrigation Test Procedure in order to confirm the
suitability of the irrigation system.
Table I: General Guidance for the Sizing of Irrigation Area (nC).
Percolation Value (seconds/mm)
Population
30-90 120-180 21 0-270
4 50 70 110
6 60 90 130
8 70 110 150
These guidelines apply to both surface and sub-surface
irrigation systems. For sites where the measured
percolation value is less than 30 (sec/mm) or greater
than 270 (sec/mm) Biocycle Limited should be
consulted regarding the design of the irrigation system.
Different configurations of irrigation areas (circular,
square etc.) are acceptable. This also applies to sites
Where split irrigation areas are needed t° obtain the
recommended total area.
No point of the irrigation area should be closer that 5 m
to any habitable building, 1 m to boundary walls or
fences and 3 m from any water course. The
separation distance from wells should be not less than
20 m except in the case of very sandy soils or gravels,
where a minimum distance of 40 m should be
maintained. The irrigation area should be down
gradient of any nearby well. Where it is not possible to
locate the irrigation area down gradient of any well
including those on neighbouring properties, a
separation distance of at least 100 m, depending on
percolation conditions, must be maintained. At least 1
m of overburden should be present between the
highest level of the water table and the invert level of
the irrigation system. A raised bank of topsoil may be
required to accommodate this.
2.5 COMMISSIONING
Commissioning will be carried out by Biocycle service
technicians after installation is complete and all
services are connected.

3.1 GENERAL
The Biocycle Waste Water Treatment System has been
designed to treat domestic waste water arising from up to
8 persons. A single system may therefore be used to treat
the waste water from two or three households, provided
the total population served does not exceed 8 persons. It
is suitable for installation at sites where a septic tank and
percolation system does not afford an environmentally
safe and acceptable means of disposing of domestic
waste water. Such sites include those where the water
table is high and where soil types do not afford good
percolation. Where the disinfection option is employed it
may be used .at sites where bacteriological contamination
of ground water must also be avoided. To ensure optimum
efficiency the drainage of the premises served must be
checked to ensure that storm water from roofs and paved
surfaces does not discharge to the system.
The system is designed and installed generally in
accordance with BS 6297:1983 Code of practice for design
and installation of small sewage treatment works and
cesspools. Due to the high quality effluent treatment
achieved (see Table 2 of this Certificate) the Biocycle Waste
Water Treatment System can be installed close to habitable
buildings, as indicated in Section 2.4.2. and Section 2.4.3
subject to any special requirements of the particular site.
The system intentionally does not have an overflow
disposal outlet. There is a minimum spare volumetric
capacity of 2600 litres so that in the event of a pump
malfunction it will continue to accept up to two to three
days discharge from the premises. The monitoring system
(see 3.2.5) will have alerted the owner to the malfunction
and this will normally be corrected before overflow occurs.
Where surface irrigation is employed the system is
designed so that any overflow will be automatically
disinfected, thus minimising the risk of any health hazard.

Installed surface area: 120 m~
3.2.3 DISINFECTION
Disinfection of waste water is available as an option· A
solid formulation, 70% active, of calcium hypochlorite
[Ca(OCI)2] tablets is used. They are retained in a
controlled release chamber so that under and over
dosing does not occur. Replenishment is normally
required twice per year and will be carried out by
Biocycle Limited as part of the mandatory inspection
and maintenance contract for each installation.

concentrations would normally be attained within a
few weeks of commissioning.
Each Biocycle Waste Water Treatment System is
supplied with a monitoring system to alert the owner to
malfunctions. The tank is fitted with a liquid level
detector which will warn of a pump malfunction. A
pressure detector will warn of an air blower
malfunction. In addition a power supply alarm will
activate in the event of a power failure to the Biocycle
unit. These detectors are connected to a fault indicator

BIOCYCLE WASTEWATER TREATMENT PLANTS
A SUITABLE ALTERNATIVE
Paper Presented to the Australian Institute
of Health SUrveyors (South Australian Division)
Mount Gambier South Australia - 26th November 1987
by Ian Walte: Managing Director BIOCYCLE Pry Ltd.
Amended 12th May, 1989.
THE BIOCYCLE AEROBIC WASTEWATER TREATMENT SYSTEMS:
INTRODUCTION
The effective collection, treatment and disposal of human
waste and wastewater has been a puzzle and a challenge to
humans since time began. It is not intended to give a
potted ],[story of how we have arrived at the stage we are
today, but suffice to say that collection and treatment
systems have developed since last century to cope with the
increasing demands for good public sanitation practices.
Authorities, both state and local, have established
reticulation systems for collection, and have developed
treatment facilities to cope with quantities of wastes
generated from communities, both large and small.
What will be discussed in this paper is the function and
operation of the BIOCYCLE system which provides a higher
level of treatment than previously obtained, and which
allows the recycling of the wastewater effluent. The
benefits of the Aerobic Wastewater Treatment System will
become obvious. The recycling of treated effluent is now a
major topic in itself, and others will advance this cause in
the passage of time through awareness campaigns and
government encouragement.
A BIOCYCLE aerobic treatment unit is a packaged wastewater
treatment plant for domestic application when mainline
sewage is not available, or where the soll types or terrain
do not'suit conventional site disposal systems, but
particularly when environmental damage wishes to be avoided.
It provides an excellent and viable alternative for those
areas which are intended to be provided with a reticulated
sewage scheme in years to come.
The treated effluent from a BIOCYCLE aerobic treatment plant
is ideal for garden or landscape irrigation. In certain cold
climates when dispersed via sub-soll drainage, it has a
distinct advantage over traditional on-site disposal systems
because of its sludge-free condition.
-2-
HOW IT WORKS
Biological sewage treatment plants for fairly small and
sometimes quite large establishments have been available for
many years. Such systems are generally based on the
activated sludge principle, followed by clarification by
means of settling; and tertiary treatment by means of
chlorination or pondlng.
The BIOCYCLE aerobic treatment plants, used for single
dwellings and small commercial concerns are somewhat
different from the conventional package treatment plant.
THE SYSTEM AND ITS FUNCTIONS
The BIOCYCLE system is divided into four principal chambers.
RECEIVING CHAMBER (anaerobic/septic)
AERATION CHAMBER
CLARIFICATION CHAMBER
4. IRRIGATION (pump) CHAMBER
CHLORINATION takes plaace between chambers 3 and 4.
THE RECEIVING CHAMBER
All wastes are received into this first chamber. Anaerobic
digestion of solids occur as a primary treatment achieving a
reduction in the B.O.D.5 level (organic loading) of up to
40%, This chamber also provides other valuable service to
the Biocycle system in that it acts as a receiving chamber
for not only organic waste but also inorganic matter, sludge
and skimmed material (sent back from the Clarification
chamber) and cellulous materials that require longer
retention for breakdown. The introduction of
Aerated/Activated sludge from the Clarification chamber
excites and further assists the digestion of solids.
sludge, (the ultimate by-product of waste), is accumulated
in this chamber and when desludglng is required, (estimated
at 9 years in the average household), then only this chamber
requires pumping out.
AERATION CHAMBER
Whilst the Receiving Chamber digests a percentage of the
organic loading, the Aeration Chamber is capable of
achieving the required treatment standard without the
assistance of the first chamber. ~.
-3-
The displaced, and partially treated waste flows from the
receiving chamber to this chamber and air is supplied by
means of a Blower (compressor) and distributed via
diffusers. The amount of air regulred is dependent upon a
calculation based on the anticipated organic loading
(B.O.D.5) and the transfer of oxygen into the water,
(increasing the dissolved oxygen level). The blower used in
the BIOCYCLE system for the individual household is
specified to treat a loading of 2 800 litres per day with a
B.O.D.5 influent loading of 250m9. per litre.
The Aeration chamber contains a submerged media upon which
grow both aerobic and anaerobic bacteria. The media is
located where beneficial bacteria thrive. A zoogleal film
of bacterial and algal matrix develops on this media thus
providing biological treatment. The type of media used in
the BIOCYCLE system has a discreet flow pattern with a big
surface area to volume ratio and self cleansing action.
The Aeration Chamber in the BIOCYCLE system is however
different in theory from an ordinary suspended growth
system. Both sub-surface anaerobic and surface aerobic
micro-organisms grow on the submerged .media. However the
anaerobic bacterial action results in a continuous reduction
of the media growth and therefore a reduction in biological
sludge accumulation.
Nevertheless, as the thickness of the materlal grows, some
separation caused by the high liquid movement, will occur.
This separation will ultimately result in excess sludge in
the aeration compartments which will ultimately flow to the
next chamber, (Clarification Chamber), for pick up and
return to the Receiving Chamber.
An amount of activated sludge in the Aeration Chamber plays
an important role, allowing additional micro-organisms to
grow on the sludge particles further assisting digestion.
In the BIOCYCLE system the capacity of this chamber allows
for a 24 hour detention time of the influent load, (16
hours, generally being regarded as sufficient: in some
commercial applications, a greater detention period may be
necessary).
CLARIFICATION CHAMBER
After aeration, the effluent flows into this chamber and is
allowed to settle down under quiescent conditions.
Sludge/undigested material settles to the bottom where it is
picked up and returned to the Receiving Chamber. Floating
matter is also collected and returned to the Receiving
Chamber.
-4-
The method adopted in the return of settled or floating
matter is via a venturi pump, (run off the air supply to the
Aeration Chamber) and is capable of automatic and continuous
operation.
The benefit of a continuous sludge/skimmer return to the
Receiving chamber provides a continuous supply of "food" to
the plant and thus ensures a "healthy" system during periods
of zero flow or extended vacancy of a residence.
From the clarification chamber the effluent is drawn-off at
below the surface level and flows to the pump chamber.
CHLORINATION
During thls flow the effluent comes into contact with
calcium hypochlorite tablets (guaranteed 70% active).
Within the BIOCYCLE Chlorinator a weir has been set and
calibrated to suit above normal water usage, and is designed
for a flow rate generated by a household of up to 10
persons, and to provide sufficient Chlorine stocks under
maximum usage with in-built safety factors to cover all
forseeable circumstances between the quarterly maintenance
calls with a 100% safety margin.
IRRIGATION (pump) CHAMBER
After disinfection, the aerated, settled and chlorinated
water is retained in this chamber to ensure a minimum 20 to
.30 minutes contact time then pumped via an irrigation system
to wherever it is required in the garden landscape area of
the property.
FINAL EFFLUENT QUALITY
A properly maintained plant produces treated waste water of
very high quality Both B.O.D.5 and suspended solids ($.$.
OR N.F.S.), are required by all Government departments in
Australia to be not greater than 20/30 mg /litre .
In relation to Faecal Coliforms the following standards:
Not more than 30 Faecal Coliform Organisms per 100 mi.
FREE CHLORINE - Not less than 0.5 mg. per lltre (0.5 ppm).
All tests on the BIOCYCLE unit thus far have never recorded
any presence of faecal coliform organisms.
-5-
IN PERIODS OF VACANCY:
A user of a BIOCYCLE system is advised to contact the
company if they expect periods of vacancy greater than three
(3) months.
INSTALLATION OF A BIOCYCLE SYSTEM.
The same installation procedures should be followed as if
installing the traditional septic tank.
APPROVALS:
In Australia, and in both the cases of a new installation
into a new.home or in an existing dwelling, it is required
to make application to the local Council for the approval of
the installation of a BIOCYCLE Aerobic Treatment System.
BIOCYCLE IRRIGATION SPECIFICATIONS
The BIOCYCLE systems irrigation water is discharged via a
25mm polythene pipe through a series of 25 to 30 micro,et
sprayheads. These sprays are placed at intervals in the
required positions on the pipe from the tank. Although the
submersible pump in the irrigation chamber is capable of a
discharge'rate of 0.13 cubic metres per minute, the type of
sprayheads and friction loss brought about by the filter and
irrigation line reduces the discharge rate to .75 lttres per
minute when 25 sprayheads are used, therefore evacuating 200
litres in approximately 10 minutes. In certain situations
additional sprayheads may be required further reducing the
flow rate.
The minimum area required for irrigation varies depending on
site conditions, however an area bf about 100 square metres
is the generally accepted average. This may be in any
configuration and with some innovative planning can provide
for a fully integrated irrigation system and provide genuine
landscaping benefits. After irrigation, nutrient removal is
achieved.
Irrigation of recreational areas and growing vegetables or
fruit must be avoided. Discharge or run-off into stormwater
easements or other drainage channels is not recommended.
All effluents must be disposed of within the boundaries of
the property.
In the case of "split" irrigation areas, BIOCYCLE will
instal valves necessary to allow the alternate use. The
system is designed to ensure that at least one irrigation
area is available for use at all times.
The Irrigation area should ideally have a vegetative cover
and the System is designed to be operative with an
evaporation rate of about 6mm per day. If the irrigation
area consists of shrubs and natives with a plant cover of
say 40% we would es.timate.a transpiration rate of about 30%
of deposited water.
COMMISSIONING:
It should be remembered that it might be necessary to instal
the BIOCYCLE System prior to building commencement,
particularly when the property, when built, may preclude
physical access to the preferred location on your site or if
it is required for the system to be used during building
operations, however some time will probably elapse between
installation and commissioning of the system.
The normal BIOCYCLE installation leaves the' System ready for
automatic commissioning.
As the BIOCYCLE is a completely natural biological process,
time must be given for the bacteria cultures to form. It
will generally take up to about four weeks for this to
occur. Whilst this settling period takes place slight odours
may come from within the system.
To assist with a more rapid settling in period it is
recommended that a cup full of ordinary garden llme is
deposited in the Primary chamber daily for the first week of
operation. This assists the breakdown of solids and usually
halves the settling-in period, or alternatively, a bucket
full of waste from an operating septic system will achieve
the desired effect. There are also several proprietary lines
of "enzyme accelerators" that can be used.
IN-BUILT SAFETY FACTORS AND ALARMS
Within the Biocycle System two alarms are installed as
warning devices. An Alarm Plate (audio/visual) is supplied
to be installed within the house, (the kitchen being the
most preferred room). The alarm plate is similar to an
ordinary light switch with two coloured lights. A switch
provides for the alarm to sound and to be switched to the
"mute" position when heard. The two lights indicate if:
1. The high WATER level alarm - designed to sound if the
water level in the Irrigation/Disinfectant Chamber reaches a
certain level. This indicates that the submersible pump is
malfunctioning.
2. The AIR pressure alarm - designed to sound if the
diaphragm blower ceases to operate.
--.7--
The householder is required to contac% the company when this
occurs and BIOCYCLE PTY. LIMITED is obligated to respond
within 24 hours.
Further, the domestic BIOCYCLE design provides for an air
space that is capable of accepting not less than an
additional I 200 litres, should the irrigation pump fail.
This gives at least 2 days capacity, in the average
household safety span, prior to the system overflowing.
However, even if the system overflows there are sufficient
chlorine stocks within the system that dissolve as the
liquld level rises, to render the overflow relatively
harmless.
MAINTENANCE OF AEROBIC TREATMENT PLANTS
All BIOCYCLE units require quarterly maintenance. In the
flrzt year after commissioning, the labour is included in
the sale price of the system and the only charge ks for
chlorine tablet replenishment. In the second and ensuing
years, the current cost of this is $175.00, but includes all
chlorine tablet replenishment.
NOTE: In Australia there are no requlrements for maintenance
or testing of the traditional septic, and consequently,
there is no knowledge after installation as to whether the
septic is working efficiently or whether it has completely
failed.
ACCEPTANCE OF THE BIOCYCLE SYSTEM
BIOCYCLE PTY. LIMITED. first gained approval to commence
manufacture of their systems in New South Wales in November
1985. Since then, blanket approvals have been gained in
South Australia/Northern Territory and Queensland. Blanket
approval is pending in Western Australia.
Preliminary approval has been gained in New Zealand with the
first two systems having now been installed in that country
and the first of five contracted systems have been installed
in New Guinea.
Negotiations are being concluded on technology transfer
agreements in Bahrain, Saudl Arabia, Italy, Israel, the
U.S.A. and Ireland.
There are now approaching 1000 domestic BIOCYCLE systems in
operation in Australia and about 100 larger commercial
(BIOCYCLE Jumbo) units in operation.
The acceptance by the general public, and local and state
authorities is mushrooming, particularly in New South Wales,
and Queensland.
-8-
Many Local Government Areas now "exclusively" specify the
BIOCYLE system or similar in preference to the out-moded
septic tank.
CONCLUSION
The BIOCYCLE systems achieve the primary objective of high
quality effluent that can be recycled for irrigation
purposes.
The BIOCYCLE system overcomes the significant community
stress caused by failed on-site disposal, illegal.discharge
and subsequent pollution of the local environment.
The BIOCYCLE system may relieve the community cost where a
reticulated mains sewer scheme is not economically viable.
Finally, the BIOCYCLE system is an acceptable alternative.

" ~ BIOCYCLE TEST RESULTS
TESTING OF THE BIOCYCLE UNIT BY THE NSW DEPARTMENT OF HEALTH
WAS CONDUCTED BY STAFF FROM THE NORTHERN METROPOLITAN
REGIONAL OFFICE OF THAT DEPARTMENT. SAMPLES FOR B.O.D. 5 AND
SUSPENDED SOLIDS WERE TAKEN BY THOSE OFFICERS TO AUSTRALIAN
ANALYTICAL LABORATORIES (a National Approved Testing
Authority {NATA}). FAECAL COLIFORM SAMPLES WERE TESTED AT
THEIR OWN LABORATORIES.
THE TEST SITE HAD TO BE APPROVED BY THE DEPARTMENT AND THE
SYSTEM WAS PLACED UNDER LOCK AND KEY DURING THE TEST PERIOD
WITH A DEPARTMENTAL OFFICER IN CHARGE HAVING THE ONLY KEY
FOR ACCESS.
IN SOUTH AUSTRALIA, THE SOUTH AUSTRALIAN HEALTH COMMISSION
WERE SATIS~FED WITH THE TESTING CRITERIA OF THE NSW
DEPARTMENT OF HEALTH AND ACCEPTED THEIR TEST RESULTS.
HOWEVER, AFTER INSTALLATION OF THE FIRST BIOCYCLE SYSTEM IN
THAT STATE, OFFICERS OF THE S.A. GOVERNMENT MADE PERIODIC
INSPECTIONS OF THE SYSTEM AND TOOK RANDOM SAMPLE TESTS, ALL
OF WHICH FELL WITHIN THEIR GUIDLINES. NONE OF THEIR TEST
RESULTS HAVE BEEN MADE AVAILABLE TO BIOCYCLE.
IN THE NORTHERN TERRITORY, THEIR GOVERNMENT ACCEPTED THE
SOUTH AUSTRALIAN RECOMMENDATION.
IN NEW ZEALAND, THEY ACCEPTED THE NSW APPROVALS.
IN QUEENSLAND, A DIFFERENT SYSTEM OF EVALUATION OF THE
BIOCYCLE SYSTEM WAS REQUIRED AND THAT PROCEDURE AND RESULTS
ARE LISTED HEREON.
IN NEW GUINEA, THEY ACCEPTED THE SYSTEM ON THE MERITS OF THE
AUSTRALIAN APPROVALS. NO FORMAL APPLICATION HAD TO BE MADE
AND CONSEQUENTLY NO FORMAL ACCEPTANCE HAS BEEN RECEIVED.
IN WESTERN AUSTRALIA, THE W.A. HEALTH DEPARTMENT HAS
APPOINTED A SENIOR HEALTH SURVEYOR FROM KALUMUNDA SHIRE
COUNCIL TO CONDUCT TESTING. THIS TESTING HAS INCLUDED RANDOM
SAMPLING OF THE SYSTEM ON A WEEKLY BASIS FOR THE FIRST FOUR
MONTHS, RANDOM FORTNIGHTLY TESTING ON A FORTNIGHTLY BASIS
FOR THE NEXT TWO MONTHS, AND IS NOW CURRENTLY BEING TESTED
ON A ONCE A MONTH RANDOM BASIS. IN W.A. IT HAS BEEN
NECESSARY TO ALTER LEGISLATION TO ALLOW THE INTRODUCTION OF
THE BIOCYCLE SYSTEM. WE HAVE BEEN VERBALLY ADVISED THAT
THEIR HEALTH DEPARTMENT ARE SATISIFED WITH THE RESULTS OF
THEIR TESTING BUT NONE OF THE RESULTS HAVE BEEN GIVEN TO US.
AT THE TIME OF PREPARATION OF THIS REPORT WE UNDERSTAND THAT
THE NECESSARY LEGISLATION HAS BEEN PUT BEFORE THEIR LOWER

ADEC Project Number 9521-W/W-229-054, Review
Dear Mr. Shafer:
I have reviewed your August 17, 1994 submittal, the information provided to this office on
the Biocycle On-site Wastewater Treatment System, and the information in this office's
files regarding the original waiver. Based on this review, I have the following comments.
From the submitted information, the effluent that will be discharged into the existing soil
absorption system will be treated to a higher level than is currently being done by the
existing wastewater disposal system. In fact, it appears that you are resolving several
existing problems regarding vertical separation distances between the groundwater and
the lowest part of the seepage pit. With the general improvement being made in regards
to separation distances and with a higher treated wastewater being discharged, your
waiver requests are justifiable. Therefore, in accordance with the provisions of 18 AAC
80.030 Drinking Water Regulations, the following waivers are granted:
1. From Class A Public Water System Source Well
To Biocycle Treatment Unit from 200 feet to 135 feet
To closest point of existing soil absorption system from 200 feet to 122 feet
2. From the lowest part of existing soil absorption system and the highest
groundwater elevation from four feet to two feet
These waivers will remain valid, as long as the following requirements are addressed.

SUBJECT:
Horizontal Separation Waiver
Lot 6, Alpha Circle, Borealis S/D, Anchorage, AK
(9021-WA-006)
Dear Ms. Hamilton:
Due to additional information submitted to this Department by Mr.
Leroy Reed of Alaska Environmental Engineering Service, this letter
supersedes our letter to you dated August 11, 1989.
The Department has reviewed the subject waiver request and hereby
waives the horizontal separation distances between the well and the
following sources of potential contaminations to:
122 feet for the existing crib, (1974)
122 feet for the existing leach line,
122 feet for the proposed leach line,
108 feet for the existing septic tank,
(1980)
(1989)
(1974)
The Department has granted these separation waivers, in part due
to the understanding that a diversion valve will be installed and
properly utilized within the wastewater system. This is to allow
for half of the wastewater system to have adequate "resting time",
to rejuvenate.
Please be advised this is an important document and should remain
with the deed of the house. These granted waivers are for a
4-Bedroom single family residence occupancy only.

SUBJECT-
Horizontal Separation Waiver
Lot 6, Alpha Circle, Borealis S/D, Anchorage, AK
(9021-WA-006)
Dear Ms. Hamilton:
Due to additional information submitted to this Department by Mr.
Leroy Reed of Alaska Environmental Engineering Service, this letter
supersedes our letter to you dated August 11, 1989.
The Department has reviewed the subject waiver request and hereby
waives the horizontal separation distances between the well and the
following sources of potential contaminations to:
122 feet for the existing crib, (1974)
122 feet for the existing leach line,
122 feet for the proposed leach line,
108 feet for the existing septic tank,
(1980)
(1989)
(1974)
The Department has granted these separation waivers, in part due
to the understanding that a diversion valve will be installed and
properly utilized within the wastewater system. This is to allow
for half of the wastewater system to have adequate "resting time",
to rejuvenate·
Please be advised this is an important document and should remain
with the deed of the house. These granted waivers are for a
4-Bedroom single family residence occupancy only.

Anchorage, Ak 99507
Dear Mr. Parks:
On November 29, 1980 we drilled'the testhole approximately 10 FL.
From the end of the trench left open by spendlove the results are
as follows:
0-3' S~IE, slight moisture (ML)
3-6' Silt, some gravel (GM)
6-9' Silt, one layer highly saturated (silt) (Mt)
9-12' Occasional gravel silt mix Mostly silt very
plastic and~saturated.(ML)
Bit wet on retrieval.
After 2 minutes water was evident in the hole. The static level
was approximately 9'. This depth matched the top of the water in
the open trench.
1'he only assumption to be reached is that the water in the trench
is groundwater and not water From the crib.
IF I can be of any assistance, please let me know.
Sincerely,
