Effective use of drones from ZDNet:

Singapore is sending out drones to monitor water quality and activities at its reservoirs. It hopes this will reduce the number of hours currently needed to perform such tasks by 5,000 man-hours.

Officers currently spend 7,200 man-hours a year carrying out various duties at these water catchment areas across the island. These include daily patrols to identify excessive growth of aquatic plants and algal blooms, which could affect water quality. Data also is collected on water activities, such as fishing and paddling, in and along the edge of the reservoir to ensure these are carried out safely.
