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.

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.
