disposed downstream or below the water inlet 142 to receive the waterflow 10. First evaporative cooler 110 may extend laterally or horizontally across the chamber 140 such that the waterflow 10 has to pass through it before being directed to the second evaporative cooler 120. First evaporative cooler 110 may be disposed below the plurality of nozzles 142N to receive the waterflow 10. Cooling apparatus 100 may include a fan 150 disposed across the air outlet 148 to draw the airflow 20 out from the chamber 140 from the top. As shown in Fig. 1, the fan 150 may be disposed above the plurality of nozzles 142N. First evaporative cooler 110 may be disposed below the fan 150. Second evaporative cooler 120 may be connected to the air inlet 146 to allow airflow 20 therethrough when it enters the chamber 140 and connected to the water outlet 144 to allow waterflow 10 therethrough when it exits the chamber 140. Second evaporative cooler 120 may be disposed downstream of the air inlet 146 to receive the airflow 20 entering the chamber 140 and upstream of the water outlet 144 to allow the waterflow 10 out of the chamber 140. Waterflow 10 exiting the chamber 140 may be collected in a water pan 152 fluidly connected to chamber 140. Water pan 152 may include a water channel 154 to channel the cooled water collected to be used where required, e.g. a condenser of a building. Waterflow 10 may be channelled directly from the water outlet 144 without a water pan 152. Second evaporative cooler 120 may extend longitudinally or vertically. As shown in Fig. 1, the waterflow 10 may flow through the second evaporative cooler 120 longitudinally and the airflow 20 may flow through the second evaporative cooler 120 laterally thus forming a cross- flow. Second evaporative cooler 120 may include one or more infills. As shown in Fig. 1, the second evaporative cooler 120 may include two infills disposed opposite each other at opposite sides of the chamber 140. Second evaporative cooler 120 may extend along the perimeter of the chamber 140 to surround the chamber 140. While the cooling apparatus 100 in Fig. 1 is shown as a vertical configuration, e.g. first evaporative cooler 110 disposed above the second evaporative cooler 120, it is possible for the cooling apparatus 100 to be arranged in a horizontal configuration such that the first evaporative cooler 110 and the second evaporative cooler 120 may be disposed laterally at the same height from the ground and the waterflow 10 from the first evaporative cooler 110 may be pumped into the second evaporative cooler 120 and the airflow 20 may be drawn laterally across both the first evaporative cooler 110 and the second evaporative cooler 120. [0033] Fig. 2 shows a flowchart of a cooling method 2000 adapted to cool the waterflow 10. Method 2000 includes receiving an airflow 20 through a first evaporative cooler 110 from a
