Final answer:
Low-flow fixtures and greywater recycling are water conservation measures widely used by hospitality properties.
Step-by-step explanation:
The water conservation measures widely applicable to and used by hospitality properties include low-flow fixtures and greywater recycling. Low-flow fixtures such as low-flow showerheads and faucet aerators can reduce the amount of water used without compromising the guest experience. Greywater recycling systems collect and treat water from sinks, showers, and laundry, which can then be reused for flushing toilets or irrigation.
