Folks,
Last week was cold, cloudy, windy and generally pretty waluigi
Winter was upon us
Or so I thought
This week though, it's been beautiful
Sunny and warm
...
I'm on-call again
But it's been really quiet
I'm 5 out of 7 days deep and I've only gotten one SCADA alarm
It was however, at 03:39AM this morning...
But still pretty good, all things considered
...
The Water Treatment Plant has been running well
Consequently, I'm not as sleep deprived as I normally would be while on-call
I'm grateful
It's great
...
I'm also excited
I managed to persuade two new lovely folks to join in with the HIVE experiment
Please welcome
and
!
The image today was taken looking out at the Reservoir with a section of the Raw Water Platform visible to the right
This structure of concrete and steel is whereupon the six raw water pumps are mounted
Three high-flow and three low-flow
Two of the high-flow pumps have variable speed drives (VSDs)
This allows the Process Technicians to adjust the flow rate of raw water moving through the plant, as required, to meet the demand for drinking water across the city
(I'm one of the three Process Techs that work here)
The third high-flow raw water pump is fixed-speed
It pumps 300 million litres of water per day when it's running
And zero litres when it's off
That's it
That's your lot
There is no in-between
We generally avoid using it because of that
