Could we use waste water to irrigate food crops?

Would using waste water (effluent) benefit the growing of food or any other crops? Would it act as a fertiliser?

This is already a common practice in developing countries. The issue in developed countries are health risks, naturally.

Wastewater is often the only source of water for irrigation in these areas. Even in areas where other water sources exist, small farmers often prefer wastewater because its high nutrient content reduces or even eliminates the need for expensive chemical fertilizers.
