You have 25 seconds to prepare and 40 seconds to speak.

Sample answer (68 words, about 35 seconds)

The diagram shows how a home rainwater system works in four stages. First, rainwater is collected from the roof. It then passes through a filter that removes leaves and dirt, before being stored in a tank. Finally, a pump sends the water to the garden and toilets. When the tank is full, extra water overflows to the stormwater drain. Overall, the system allows households to reuse rainwater efficiently.

Keep a steady pace and don't stop for more than 3 seconds; a long pause can end your recording. Fluency and pronunciation count for more than describing every detail.
