The town of Springhill frequently must declare a water emergency, making it temporarily unlawful to use water for such nonessential purposes as car washing. █████ ███████████ █████ ██ ███████ ██ ██████████ █████ █████████ █████████ ████████ ██████████ ███ █████ █████████████ █████████ ██████████ ███████████ ████████████ ███████ ████ █████████ ████ █ ██████ ███████ ████ ███ ███ ███ ██████ ██ █████ █████ █ ███████ █████ ██████████ ███ █ ███████████ █████████ ████ ████ █████ ███ █████████ ██ ████████
The author concludes that Springhill discourages water conservation. This is because households in Springhill pay a low monthly flat rate for their water, and are only charged per liter if they exceed a threshold.
The author assumes that the threshold is high enough that most households don’t end up paying the substantial per-liter rate once the threshold is exceeded.

The argument centers around whether Springhill's normal policies currently discourage water conservation. How emergency measures are enforced isn't relevant to that.

We have no idea how high the threshold was to begin with. If it's not extremely high already, refusing to raise the threshold suggests a concern with conserving water, which potentially even weakens the author’s argument.
The threshold is ████ ██ █ ████ ██████ █████ ██ ██████ ███ █████ ████████████ ██ ████ ██████████ ██ ███████████
Most households never hit the threshold, which means they never pay the per-liter fee. This strengthens the argument by showing that Springhill indeed isn’t encouraging people to cut back on their water usage.
The threshold is ███ ██ ████ ██ ██████████ ██ ██ ██ ██ ███████████ ██████
This doesn’t give us enough information, because we don't know anything about the neighboring towns. The threshold may still be high enough that most people never pay the per-liter fee—we can't say.
The threshold remains ██ ███ █████████████ █████ █████████ ██ ███ █████ █ ██████ ██ ████████ ██ ███ ██████████ ████ ████████
This simply tells us how the threshold is set. We need to know if it’s set high enough that most households never pay the per-liter rate. Since this doesn't tell us, it's irrelevant.
