The provided diagram illustrates the complete, multi-stage process by which rainwater is collected from residential properties in an Australian town and subsequently treated to produce drinking water.
Overall, the process is a linear, four-stage cycle that begins with the domestic collection of water and concludes with its final distribution back to the homes after passing through a central purification system. The entire operation is designed to ensure a constant supply of potable water through recycling.
The system commences with the collection phase, where rainwater is captured from the roofs of multiple houses and channeled via a drain into a communal underground pipe network. From this network, the water is first directed through a single Water Filter, which serves to remove large particulate matter and debris. Following this primary filtration, the partially cleaned water flows into a substantial Storage tank.
The second half of the process focuses on intensive purification. Water is pumped from the storage facility into the separate Water Treatment tank. This is the crucial stage where Chemicals are introduced to the water to purify it, ensuring it is safe for human consumption. Finally, the treated Drinking Water is then distributed via pipes back up to the individual houses, completing the cycle and making it available for household use.
