Ahead of World Water-Tech North America next month, three water industry experts share their thoughts on the future of water reuse. 

The future of water reuse is simple: There must be more of it. As climate change continues to constrain water supplies, the need for reuse is increasing. As the driest city in the driest state in the nation, nearly all indoor water use in Las Vegas is reclaimed and sustainably returned to Lake Mead, our primary drinking water source for indirect reuse.

As a result, reducing consumptive water uses is a key focus for our organization, and water-intensive evaporative cooling is one area that has reuse potential. Implementing technologies and methodologies for reclaiming and reusing water for evaporative cooling systems can not only expand the use of recycled water, but also improve water efficiency within communities. This requires fostering partnerships in the business community to engage and participate, which can be a challenge, and may even require financial incentives to help the business community transition to more efficient cooling systems.

Zeynep Erdal, Director: Integrated Solutions & Capabilities, BLACK & VEATCH:
Advances in treatment technologies, improved monitoring and control, public and regulatory understanding for solutions, and economics are all converging to elevate reuse projects at a time when water reuse is emerging as a key piece in the water system resilience solutions.

Rethinking and climate-proofing our water systems, rapid deployment of proven technologies and allocating the necessary funds at regional scale will require collaboration between regulators, owners, and engineers. Integrated resource management strategies reveal opportunities to extract resources that would otherwise be wasted, enhance water quality, and lower costs through cost-sharing opportunities. This is truly the golden age for reuse.

John Kmiec, Director, TUCSON WATER:
Recycling water will continue to be a critical tool in a resource portfolio for water utilities in water resource-limited areas. The ability to use, clean, and re-use the same drop of water for multiple functions will allow flexibility in development and community growth. Many agencies spend large amounts of time and money acquiring and securing water resources. Once you have them, why not use that resource to its fullest potential?’

Decentralizing water treatment for on-site commercial purposes can be a great partnership between a utility and an industry.  Creating an environment where localized water reuse can offset infrastructure needs may allow for development on the periphery of communities where traditional infrastructure is limited or too costly to extend.

These three industry leaders will take the stage at the summit to discuss ‘The Future of Water Reuse: Decentralized and Onsite Solutions for Drought Mitigation’ on September 28 at 11.45am PT.
