Welcome
Dear valued clients and partners
On behalf of the TRILITY Group and its shareholder, we want to wish
you and your family a safe and happy festive season. As the year end
draws near, I would like to take this opportunity to thank you for a
good year, despite its challenges. The success of the TRILITY Group is
based on the relationships we have built over the years, and we really
wouldn’t be where we are today without you.
For me, reflecting on this year has brought mixed thoughts, for the
year contained so much turmoil, unexpected challenges, and sorrow.
As nations, Australia and New Zealand managed the pandemic well
compared to other countries - yet, it caused much devastation for so
many. Our thoughts go out to those across the world that have been
and continue to be affected. We cannot change the past; however,
we can undoubtedly change the future, and it is crucial for us to also
reflect on the many positive learnings that came out of the pandemic.
2020 began with great uncertainty and ends with greater optimism.
TRILITY’s standout achievement this year brings pride. As a company,
we responded early and rapidly to the many challenges we faced,
which was only possible due to our employees’ dedication and you,
our clients, and partners. Therefore, we thought it fitting to share
some of the great work achieved across the year.
From the entire TRILITY team, it’s been a privilege to work with you
and the communities we serve, and we look forward to working
with you all again in 2021.

The MCC boasts contributing to several historical milestones including
drafting the first set of rules for Australian Rules Football and hosting the
first-ever game of test cricket. Along with the playing of cricket, today’s
MCC is an umbrella organisation for hundreds of participants in 11 sporting
sections. The MCG was built in 1853 and, since then, has established a history
that compares favourably with any other in the world. Located in the heart of
Melbourne with a total capacity of 100,024, Australia’s favourite stadium is
the birthplace of Test cricket and the home of Australian football.
Surrounding the MCG are the grounds of Yarra Park, the hub of Melbourne’s
Sports and Entertainment Precinct. In summer, the recycled water is used to
irrigate the Yarra Parklands. In winter the water is used for toilet flushing and
wash down for the MCG. The Yarra Park WRF is a 600m3 per day Class A
sewer mine owned and managed by the Melbourne Cricket Club. The plant
was constructed in 2011/12 with practical completion being achieved in
November 2012.
On April 1 2020 TRILITY began a three year tenure to oversee the Operations and Maintenance (O&M) of the Yarra Park Water Recycling Facility (WRF) which is
owned and managed by the Melbourne Cricket Club (MCC). The facility is innovatively located beneath the Yarra Parklands adjacent to the Melbourne Cricket
Ground (MCG). The prestigious MCC was founded in 1838 and is regarded as the oldest sporting club in Australia with a membership base of 102,800 and
225,000 registered on the waiting list.

TRILITY partners in an industry placement scheme
Max Curtis paired with TRILITY and joined the Macarthur Water Filtration Plant
Operations team in early January to work on the optimisation of backwash parameters
In late 2019, TRILITY engaged with the University
of Sydney’s Chemical Engineering department to
participate in their industry placement scheme.
The Engineering Sydney Industry Placement Scholarship
(ESIPS) and Major Industrial Project Placement Scheme
(MIPPS) program pairs high-achieving students with
industry partners to work full-time on a nominated
project for six months. Max Curtis (ref. picture) was
paired with TRILITY and joined the Macarthur Water
Filtration Plant Operations team in early January to work
on the optimisation of backwash parameters.
During his six month secondment, Max slotted
seamlessly into the Macarthur operations team and
made excellent progress while on a steep learning
curve in drinking water treatment. His time on site
was made even more challenging due to the water
quality changes following heavy inflows to greater
Sydney’s reservoirs

tenance Contract
Yarra Park Water Recycling Facility pumps
Entrance to the Yarra Park plant
The WRF operates in two distinct modes throughout the year, summer and winter. In summer mode, the plant produces 600m³ per day of Class A water for
irrigation of Yarra Park. In winter mode, the plant produces 200m³ per day to supply water for toilet flushing and wash down within the Melbourne Cricket
Ground. Water is also supplied to Richmond Football Club for irrigation of Punt Rd Oval during the summer period.
In amidst all the planning, adapting, and responding to COVID-19, the Melbourne Cricket Club awarded TRILITY a three-year O&M contract for Yarra
Park Water Recycling Facility.
This contract required the team to transition in 16 days instead of the usual 6 - 12-week process time. Our team of experts consisted of; people on the
ground in Victoria and remote teams from Adelaide and Townsville.
Day one, TRILITY was ready to go without any issues; this is a real tribute to our Operations, Solutions, and support services teams for delivering on our
promise to our customer.

2020 saw the Macarthur Water Filtration Plant upgrade project come to a close; despite the many challenges faced due to COVID-19.
The upgrade was conducted on a brownfield site (meaning the site had to remain operational at all times). The team faced COVID-19 restrictions and endured
volatile weather conditions, install and water quality challenges along the way.

The raw water tanks form an integral part of the supply system to get water
from Broughton Pass Weir on the Cataract River, to the head of the Macarthur
Water Filtration Plant three km away. This involves a two-stage pumping
process with six low lift pumps, a balance tank, four high lift pumps, and two
raw water storage tanks at the top of the hill, each of 5ML capacity. Each of
the raw water tanks is fabricated from steel plate and is 33.06 metres in
diameter with a wall height of 7.80 metres.
From the raw water tanks water flows by gravity through the plant and all
the way to Campbelltown, 15 km away. Being free of any chemicals, the raw
water tanks tend to develop their own ecosystem of weeds and fish, which
presumably pass through the two stages of pumps as eggs or fingerlings.
The image shows cleaning one of the two raw water tanks. The clean takes
approximately five days to complete.

Sample and chemical dosing lines
TRILITY constructed two 10 ML tanks and installed pipelines during stringent ‘social distancing’ guidelines. Even more challenging was installing the
interconnecting of pipework, tanks, and filter cells while ensuring 24/7 operations.
A low voltage motor control centre (LVMCC) was manufactured in South Australia and trucked across. Once installed, the team TRILITY Solutions, Operations,
and the client conducted 12 major shutdowns, which required a great deal of planning and within a very tight timeline. The shutdowns allowed the electrical
systems, raw water and treated water process, and chemical dosing system to be thoroughly tested and to ensure operability.
In addition, the upgrade integrated our KOIOS DatalytiX service to harvest data from the operational SCADA systems and Historian for cutting edge machine
learning and data science to deliver real-time high-performance key statistical modelling, dashboard visualisation, validation, and reporting through a secure
web interface.

For more information please contact Adrian Blinman, Manager
Business Growth: Adrian.Blinman@trility.com.au
In early 2019, Operations discussed the option of converting the disinfection
system at the Bamaga Water Treatment Plant in the Northern Peninsula Area
(NPA) from sodium hypochlorite to gaseous chlorine. The conversion offered
the client various benefits and cost savings.
While the benefits for chlorine gas are the reduced by-product formation,
which decreases the potential of Trihalomethanes (THM) formation - resulting
in better disinfection and overall water quality, the overall focus was around
cost reductions and safety-related operational issues faced with sodium
hypochlorite disinfection.
Some of the inherent operational issues experienced with the existing sodium
hypochlorite disinfection were:
•
The availability of supply of sodium hypochlorite (supplied in 1000lt
Intermediate Bulk Containers (IBCs) on an overnight ferry from Cairns)
•
The degradation of sodium hypochlorite strength, particularly during
the hot summer months
•
Subsequent constant dosing rate changes required to maintain
consistent disinfection
•
Extensive storage requirements (and subsequent degradation) of
sodium hypochlorite on-site during the wet season; which is typical
during the summer months
The project provides the client with full in house services covering;
•
In-house chlorine training package for all on-site staff
•
Service and maintenance on a six-monthly and annual basis
•
Spare parts management for the chlorine system
•
Off-site technical support when required
The financial evaluation showed a substantial cost saving of over $90k
per year. Sodium hypochlorite conversion to gaseous chlorine presented a
3.5 payback period, including all training requirements and
other on-costs associated with chlorine gas.
Construction and commissioning of the conversion were completed on time
despite procurement constraints outside of TRILITY’s control. We engaged
local contractors for civil works and demolition works, which has resulted in
us having stronger relationships within the community.
An eye for detail was evident throughout the entire project with the
completion of all permits, JSEAs, and demonstration of working safely at
all times, having reported no LTIs for the project’s duration. As part of the
handover to the site operational team, our in-house service team and training
arm conducted a final practical training module providing our operators with
certification in Operate and Control Liquified Chlorine Gas Disinfection.
The overall project has resulted in a robust, cost-effective plant and
improved water quality solution for the Northern Peninsula Area (NPA)
and its communities.
