1.3.14 Installation of motion sensor faucets

Description

A motion sensor faucet is a faucet equipped with a proximity sensor and mechanism that opens its valve to allow water to flow in response to the presence of a hand or hands in close proximity.

Benefits

  • Easy to operate

  • Stop the spread of germs and bacteria

  • Prevent water overflow

  • Prevent scalding injury

  • Improvements to sensor-controlled fixtures and to low-and no-flow toilets and urinals

Limitations

  • Most touchless faucets operate on battery or A/C power and require sensors to work. This can be costly and inconvenient when the batteries run out and need to be replaced

  • It is often inconvenient to have a touchless faucet in a sink where different temperatures of water are needed

  • The installation process can be complex

Economic assessment

On average, the return on investment for sensor devices is about 30%. The higher the water costs, the higher the return. The lower the water costs, the lower the return. The payback period is about 3-6 months.
