The diagram illustrates the process of collecting and treating rainwater for potable use in an Australian town.
The system comprises five distinct stages, commencing with rainwater collection and culminating in the delivery of treated drinking water, while excess water is appropriately drained.
Initially, rainwater is captured from rooftops and paved surfaces through a series of pipe systems, directing the water into a cylindrical filter. This filtration mechanism is crucial for removing debris and impurities prior to further processing. Following filtration, the collected rainwater is channeled via pipelines into a rectangular storage reservoir, where it is temporarily held in anticipation of treatment.
Subsequent to the storage phase, the water is transported to a square-shaped treatment facility. At this juncture, chemical agents are introduced to disinfect and enhance the quality of the water, rendering it safe for human consumption. Ultimately, the treated water is conveyed through pipelines to household faucets, facilitating accessible drinking water for the town’s residents, while any surplus water is expelled through a dedicated drain outlet.
