Melbourne water restrictions disallow filling pools from the mains water, so now people pay to have it trucked in from country Victoria.
The direct consequences of this are:
- Depletion of acquifers (underground water) where this water is pumped from
- Carbon emissions from pumping from the ground, truck transport, then pumping from the truck to the pool.
The average pool would only get used about 15 days in a year in any case.
