Is the water purified before or after being supplied to the building?

[rama9]

This machine purifies water supplied to the building.
​

I am confused whether this means the water is purified before or after being supplied to the building.

 

[Matthew Wai]

I think both are possible.

May I ask where you found the sentence, rama9?

 

[rama9]

I created this sentence to make clear my understanding.
If this sentence has two meanings, I would like to know how to modify this sentence such that the meanings can be distinguished.

 

[Matthew Wai]

This machine will purify the water before/after it is supplied to the building.

 

[rama9]

In fact, I would like to know the usage of "water supplied".

Is it possible to use the phrase "water to be supplied" to describe that the water is purified before being supplied to the building, and to use the phrase "water having been supplied" to describe that the water is purified after being supplied to the building ?

 

[Matthew Wai]

I thought of 'water already supplied'.

I think the supply of water is not an issue as water flows continuously through pipes connected to a building, unless it is cut off/turned off.
Water undergoes purification/filtration as it enters a building. If it is before the building, it is done at the source, which is a water treatment plant.

"It" could mean the machine to purify the water.

Water doesn't have to purified as it enters a building. There are small devices available in the UK that users connect to the pipes directly under their own sinks/baths. The water enters the building in whatever condition the water supply company chooses but the small device then makes changes to the quality of the water no more than a couple of feet or so from the taps.

'It' is closer to 'water' than to 'machine'.

We purify our water twice: first with a green sand system that cleans our well water on its way into a big storage tank, and again with a dual cartridge system that uses paper and activated charcoal before delivering it to our drinking-water tap. I'm fairly confident the stored water is safe, but it has plenty of time to grow bugs while it's sitting in the tank. Of course we installed the under-the-sink system long before the green sand system, and there was no reason not to keep using it.

 

[rama9]

Is there a difference between "water supplied" and "water that is supplied"?

Water supplied to this building needs to be tested.
Water that is supplied to this building needs to be tested.

I created these sentences. I am confused whether there is a difference between the two.

Specifically, I would like to know whether the first means that the test needs to be performed after water is supplied to the building, and the second means that the test needs to be performed before water is supplied to the building.

rama9: can you tell us why you started a new thread on this instead of continuing the discussion in the other one?

I have now merged the two threads.
