By transforming this waste into a valuable resource, we can reduce CO2 emissions, power our economy, and safeguard our water sources. The untapped potential of wastewater is an opportunity for countries worldwide to make the most of this underutilized resource.
Recognizing Wastewater: A Hidden Treasure
Wastewater is often overlooked as a valuable resource, but it holds untapped potential that can benefit both our environment and our society. Recognizing the hidden treasure that wastewater represents is crucial for sustainable development and climate adaptations. With the wake of recent events and extreme weather conditions, including flood risks, it becomes evident that our dependence on traditional water supply methods needs to shift towards solutions that value the more sustainable use of wastewater. By harnessing its potential, we can explore resource efficiency, such as the production of biogas, electricity, heat, and growth-promoting fertilizer. Reclaiming and safely reusing wastewater can not only contribute to the goals of sustainable development but also offer resilience in the face of climate change adaptation measures.
Moving Beyond the Stigma: The Positive Side of Wastewater
Wastewater has long been seen as a burden, but there is untapped potential in this often-overlooked resource. For example, wastewater can be used for irrigation purposes, reducing the strain on freshwater supplies. Expansion strategies and intensification of wastewater treatment capacity can allow for the safe reuse of wastewater, creating a sustainable water supply. This approach has already been successfully implemented in Europe, where canals, for example, have been used to distribute treated wastewater for agricultural use in croplands. By expanding the use of wastewater relative to freshwater, a scale analysis study showed that water conveyance and water quality requirements could be met in countries like China, Spain, and Israel, particularly in regions prone to drought risk, such as Asia. Wastewater reclamation systems, like the one in Po, Italy, have proven to be effective pathways for reducing water scarcity risks. This work was presented at the Assembly Conference and is a significant step towards recognizing the positive potential of wastewater.
The potential for wastewater expansion scenarios is not limited to Europe. In North America, for example, changes in wastewater treatment capacities could play a crucial role in addressing water scarcity. The United Kingdom, for example, has recognized the untapped potential of wastewater and has made it a part of their development agenda. Sewage sludge, as a by-product of wastewater treatment, can also offer opportunities for resource recovery. By reclaiming and reusing 100 percent of the wastewater it produces with a Zero Liquid Discharge approach, the environmental impact of our built infrastructure and energy systems can be reduced. Furthermore, urban water-use efficiency improvements could decrease statewide urban water use by 2.0, making wastewater an essential resource for sustainable water management. The importance of recognizing the untapped potential of wastewater cannot be overstated, as it holds the key to ensuring a reliable water supply for future generations.
Wastewater as a Viable Resource
Wastewater is often overlooked as a viable resource, but it holds huge untapped potential. In terms of quantity, wastewater supply can be significant, especially in densely populated areas. A summary of water quality in many countries shows that freshwater resources are degrading due to increasing demands and pollution load. Neglecting wastewater management can result in environmental degradation, health challenges, and a burden on water resources. However, if treated properly, wastewater can be safely reused, reducing the demand for freshwater supplies. Efforts towards resource recovery and energy generation from wastewater are gaining momentum. For example, sewage sludge, a by-product of wastewater treatment, can be converted into energy. In fact, some places have managed to reclaim and reuse 100% of the wastewater they produce, setting a benchmark for others to follow. Overall, recognizing the untapped potential of wastewater is crucial for reducing the environmental impact of our built infrastructure and energy systems, and for ensuring the well-being and livelihoods of communities.

Steering Wastewater Management Through Water Pollution Control Plants
Water Pollution Control Plants play a crucial role in steering wastewater management and unlocking the untapped potential of wastewater supply. These plants are responsible for treating wastewater and ensuring its safe reuse or disposal. The program managers and business development teams at these plants work diligently to develop processes that maximize resource recovery initiatives. For instance, Princeton University’s Waste Services Business Development Team in partnership with Wood Leidal and the WTD Biosolids Policy Liaison and Principal Technologist are exploring innovative energy initiatives such as converting wastewater solids into natural gas. By implementing such initiatives, water pollution control plants are not only reducing the environmental impact of our built infrastructure and energy systems but also turning wastewater from a waste product into a valuable resource.
One example of the impact that water pollution control plants can have is demonstrated by the efforts of the Toronto Water Technologies Committee. This committee sponsors research studies and provides support to member municipalities in their quest to reclaim and reuse 100 percent of the wastewater they produce with a Zero Liquid Discharge (ZLD) approach. Through these collaborative efforts, Toronto aims to become a model city for sustainable water management practices. By treating and safely reusing wastewater, not only does Toronto address the issue of water scarcity, but it also reduces the strain on freshwater supplies. Urban water-use efficiency improvements could potentially reduce statewide urban water use by 2.0 percent, according to a study conducted by the Water Technologies Committee. With the untapped potential of wastewater supply, water pollution control plants have the power to make a significant positive impact on the environment and contribute to a more sustainable future.
Water Pollution Control Plants as Catalysts for Wastewater Potential
Water Pollution Control Plants (WPCPs) play a vital role as catalysts for the untapped potential of wastewater. These plants are designed to ensure permit compliance and address climate action and environmental concerns. With an engineering degree and experience in wastewater treatment, professionals in this field are responsible for the development, operation, and evaluation of process efficiency in WPCPs. They actively work towards water reuse, leading to the reduction of water scarcity. For instance, the Washington Suburban Sanitary Commission, in partnership with DC Water, is implementing innovative projects like the sewer heat recovery pilot and the carbon district energy systems. These initiatives aim to recover energy from wastewater and reduce natural gas use in vehicles, thereby leveraging the untapped potential of wastewater for sustainable development.
WPCPs also play a crucial role in reclaiming and reusing wastewater. By implementing state-of-the-art technologies and innovative business models, these plants have the ability to reclaim and reuse 100 percent of the wastewater they produce with a Zero Liquid Discharge approach. This not only reduces the environmental impact of our built infrastructure and energy systems but also provides a sustainable source of water.
