PhishCo runs a number of farms in the arid province of Nufa, depending largely on irrigation  Now, as part of a plan to efficiently increase the farms' total production, it plans to drill down to an aquifer containing warm, slightly salty water that will be used to raise fish in ponds
The water from the ponds will later be used to supplement piped-in irrigation water for PhishCo's vegetable fields, and the ponds and accompanying vegetation should help reduce the heat in the area of the farms
Organic waste from fish in the pond water will help to fertilize fields where it is used for irrigation.
