The diagram illustrates how rainwater is harvested and then treated to drink in an Australian town.
Overall, the purification of stormwater involves various stages, commencing with collecting rainwater from individual houses and ending with distributing purified water to the respective households.
To begin, the precipitation from the sky is collected and allowed to flow into a single drain in every house. Then, the water from the drain is directed into a single larger pipe. The pipe is connected to a small chamber called a water filter, which aids in removing the larger and suspended impurities in the collected water. Subsequently, the filtered water is collected in a larger chamber called a storage tank, where sedimentation takes place to settle colloidal impurities.
After storage, the water is passed to a treatment chamber where disinfection, such as chlorination, is done to kill pathogens by adding chemicals. Finally, the water is deemed potable and distributed to the nearby households in the town through a distribution system.
