The correct answer is indeed that using final plant effluent in cooling towers is considered a beneficial way to reuse treated effluent. This practice reflects the principles of sustainability and resource conservation by making effective use of treated wastewater, which can contribute to reducing the overall demand for fresh water resources. It demonstrates an innovative approach to managing water in industrial settings, where cooling towers often require substantial volumes of water.

Utilizing treated effluent in cooling towers can lead to cost savings and efficiency improvements, as it alleviates dependence on potable water sources. This recycling of wastewater not only maximizes the use of existing resources but also helps to mitigate environmental impacts associated with water extraction and wastewater discharge.

In contrast, referring to this practice as wasteful or unnecessary overlooks its potential benefits and practical applications in resource management. The notion of water discharge violations does not apply when effluent has been appropriately treated to meet the necessary quality standards for reuse. Lastly, labeling it as an unnecessary cost fails to recognize the long-term savings and environmental benefits that can result from such reuse strategies.
