affecting both the people and animals living there [9]. However, the WLDS makes its users more aware of their water usage and decreases overall usage. If the WLDS does indeed reduce its customers’ water usage, its benefits may outweigh its costs. Assuming it reduces each user’s water consumption by only 2%, 1 million installations, and an average household water usage of 360 gallons per day [23], we save 7.2 million gallons of water per day. These savings exceed the water costs to operate a large fabrication house of 4.8 million gallons per day [22]. Increased water savings can also save energy, and outweigh the energy cost of manufacturing the Smart Water Meter since much of our energy goes toward transporting and treating water. Manufacturability The WLDS serves as an easy-to-use control box requiring no user input beyond initial installation of the water sensors and motor. As a result, users likely struggle when attempting to fix malfunctions, and when they occur, instead buy a new unit. While this benefits profit, it also leads to less sustainability as more units require more resources. The WLDS must last a long period necessitating a quality build. With no regular maintenance required, the unit requires very little upkeep associated with the product aside from power costs. The product could potentially include easily replaceable internal parts as an upgrade, but this would drive up manufacturing costs. Also, the implementation of the electronics within the WLDS requires the use of rare earth metals. Users can help sustain this resource if they disable the components and recycle them correctly. However, this often does not happen resulting in aggressive unsustainable consumption of resources. The modular design of the WLDS allows the individual manufacturing of the modules. The circuitry likely requires the longest manufacturing time due to its small size and precision design. The other components such as the microprocessor and water sensors come pre-made and ready to integrate into the assembly. Installation of the WLDS consists of placing the water sensors, connecting the motor to the water pump, and supplying power from a nearby wall outlet. Sustainability The WLDS strives to find leaks before any serious damage occurs to the user’s house. The system needs minimal maintenance for the sensors used to monitor leakage [7]. The system only requires connection to residential wall socket voltages to perform its functions. Potential improvements, the incorporation of a solar panel to reduce energy usage would make the product greener for the environment. However, the implementation of a solar panel would require a battery to store the resulting charge. The batteries contain chemicals such as sulfuric acid which can harm the environment. The WLDS could also potentially benefit from a wind generated power source depending on average weather conditions of the region.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
