Abstract

With decrease rainfall in parts of the world, increase in population and an increase in demand for fresh foods, water conservation is becoming one of the biggest challenges today. A possible solution to this is wastewater reuse. However, one of the biggest challenges with wastewater reuse in food production is the uncertainty of the nutritional quality of produce. Combining the hydroponics method of growing edible food crops while using secondary treated domestic wastewater requires less space than traditional agricultural methods. This also aids in water conservation by reusing the treated effluent. The nutritional quality of tomatoes and silver beet growing in secondary treated domestic wastewater were compared to those grown in a commercially available hydroponics solution, as well as, produce purchased from a local supermarket. The tomatoes and silver beet were analysed for total caroteniods, total soluble solids and ascorbic acid concentrations. The nutritional quality of the wastewater grown tomatoes and silver beet was comparable to those grown in the hydroponic solution and those purchased.
