Fight Your High Water Spend with On-site Water Recycling

Catherine Osborne

If you’re like most of ENGIE Insight’s commercial clients, your company’s water bill is an ongoing source of frustration. Many of you have already implemented water-saving measures—reducing overall consumption—only to see water-related expenses continue to go up. Why does this happen? Water costs are rising steadily. According to aggregated data from ENGIE Insight’s (formerly Ecova) North American clients, water accounted for approximately 11% of utility costs in 2015—up from 8.5% in 2008.

I recently co-presented the ENGIE Insight-sponsored webinar, Innovative Water Technologies: On-Site Water Recycling Solutions for Commercial Facilities. This webinar allowed us to establish the importance of strategically reducing water usage onsite at commercial facilities by using innovative reclamation, reuse and recycling strategies. By implementing some of our recommended strategies, you’ll be able to reduce the amount of freshwater consumed and drive down water costs to better position your business for the future. I’d like to share some of the webinar’s key insights with you and encourage you to watch the 30-minute on-demand version of the webinar.

What is onsite water recycling and what are the benefits?

Planned onsite water recycling projects use technology to speed up the natural water cycle with the goal of beneficially reusing or recycling a reclaimed water supply. Performing on-site water recycling means this activity occurs entirely within the boundaries of your facility, without purchasing recycled water from outside sources. On-site water recycling can yield numerous benefits for your company and the community: resource savings, financial savings, risk mitigation, decreased wastewater discharges, decreased volume of wastewater to treatment plants and decreased pollution.

Our webinar explored several innovative onsite reuse and recycling solutions, including:

  • Cooling towers. Businesses can reduce the amount of fresh water intake to their system by using monitoring and advanced filtration technologies. When combined with low temperature evaporation and crystallization technologies, businesses can achieve Zero Liquid Discharge (ZLD), which means that all solids are extracted and there is no discharge of wastewater to the drain.
  • Graywater recycling. Graywater solutions for commercial businesses capture relatively clean water from bathrooms and kitchens, or condensate from your AC system, and recycle this water for a second purpose. Graywater systems come in several different varieties.
  • Rainwater harvesting. Gathering rainwater and storm water—either via a series of filtration, sanitation and storage systems or a fully-automated rain harvesting system—can significantly reduce potable water demands. Rainwater is typically used for toilet flushing, irrigation and cooling tower make-up.

The rising cost and increased scarcity of water continues to be both a global issue and a concern for many businesses. On-site water reuse and recycling offers an economical solution for achieving resource savings, financial savings and risk mitigation.
