Returning middle and high school students in Walnut are adding an extra item to their agendas – helping members of their community monitor their home’s water usage. Dubbed Project Bright, the students earn community service hours by engaging with the public over the environmental and fiscal benefits of more efficient water usage. They spot any leaks with the help of water sensor technology, Flume, provided through the Walnut Valley Water District. … When water flows through a water meter, a magnetic disc spins inside the meter. The rate at which this disc spins indicated the water’s flow rate. The Flume Water Sensor straps onto the meter to measure the magnetic field.
