Faucet aerators, which break the flowing water into fine droplets and entrain air while maintaining wetting effectiveness, are inexpensive devices that can be installed in sinks to reduce water use. Older restroom faucets may have flow rates of 2.2 gal per min (GPM) or higher, so significant water savings result from simply installing new faucet flow-control devices (aerators) with a 0.5 GPM flow rate. Efficient small kitchen sink faucet aerators use 1.5 GPM. The use of foot pedals at handwash stations also saves water [14]. These aerators mix air into the water as it leaves the faucet, reducing both the flow and the amount of splashing, while increasing wetting efficiency.

To reduce the amount of water that comes out of the faucets, simply partially close the supply valves under the sink. First, open the faucet fully, then crank down the supply valve until you get the flow you want. Faucet aerators also work to conserve water, because the air introduced takes up some of the volume of the water stream. If the end of the spigot has threads, add an aerator.

The present study also aims to understand the household water usage behaviours among the sample of participants in Qatar. The participants are asked to report in detail their daily water usage activities as well as any water saving appliances they have installed in their homes. The use of water-saving devices such as low-flow taps and toilets, drought-resistant plants, faucet aerators and so on, are common techniques of reducing water consumption. For example, a study of 100 resorts in the United States found that faucet aerators, low-flow devices, dual-flush toilets and greywater recycling systems were associated with reductions in water consumption of upto 23% (Bruns-Smith et al. 2015). A similar in-depth interview study found that the installation of low-flow tap fittings and sensors were the most popular water saving devices among 23 hotels in Hong Kong (Chan, Okumus, and Chan 2020). Gardens are an important feature of contributing to high water use in houses, and using native and drought-resistant plants have been shown to be one effective technique for saving water (Kelly and Williams 2007). We therefore hypothesise that: Hypothesis 1.7. The use of water saving appliances will be associated with lower levels of water consumption.
