IES WEBINAR: INNOVATIVE WATER TECHNOLOGIES: ON-SITE WATER RECYCLING SOLUTIONS FOR COMMERCIAL FACILITIES

On a daily basis, we are presented with the opportunity to have a positive impact on the way that water is managed and used while minimizing the effect of rising water cost on our businesses.

Sustainability-minded professionals that have already implemented low-cost water conservation and efficiency projects are now asking themselves, “what’s next?” and “how can we get more from our water?”

On-site water recycling offers more creative ways for companies to cut back on water use across sites by reusing water that has already been used once.

Join Ecova to learn more about:

Where water goes beyond the drain and how you can chose to reclaim and reuse water The benefits and identification of on-site water recycling opportunities Solutions, technologies, challenges, and guidelines for on-site water recycling
