United Nations 2023 Water Conference

United Nations hosted the 2023 Water Conference in New York March 22-26. ERC companies that attended included Epic Cleantec, Gybe, Watergenics and Waterplan. In our new blog, we provide a good roundup of what went down. (I was traveling in Israel during the conference and will report on that trip in another post.)

New Investment in Irrigreen

Irrigreen was created to apply inkjet printing technology to smart irrigation to reduce watering by up to 50%. Within the United States, irrigated turf grass is 2% of the land mass of the continental United States, making it one of the largest crops by acreage. So how can we make an impact here?

Irrigreen is the best solution I've seen to do just that with the potential to massively reduce demand. How does Irrigreen accomplish this? Instead of a dozen sprinklers with overlapping sprays, Irrigreen installs one patented, internet-connected sprinkler head with 16 separate emitters in the center of the lawn directing its spray precisely based on a digital map. You can design your own system by going to and learn more in this story in Techcrunch.


ERC Portfolio News

Job Openings at Portfolio Companies

  • Waterplan is hiring across marketing, sales, customer success and product.


Indigenous Wisdom

The world's largest ever dam removal project has begun. This effort is crucial to sustain the many tribes whose culture are intertwined with the Klamath River and the salmon that call the river home. During my time as the Klamath River Project Director for The Nature Conservancy of California, I learned how the tribes, ranchers, farmers, and many local residents all vied for recognition and inclusion in decision-making. I also learned how important listening, just listening to the stories of many people, was to help find common ground. Thousands of people over the last 20 years contributed to making this restoration happen especially the local tribes and conservationists.

I'm proud of Echo River portfolio company Gybe for providing water quality monitoring technology and services for the restoration of the river.

Gybe sensors on the Klamath River in California

Researchers will rely on Gybe's observations to monitor how the river may improve across parameters like temperature, sediment and harmful algae. It's hard to comprehend just how many stakeholders are involved in this restoration effort. "Many of these researchers are affiliated with universities, or state and federal agencies, and some are from the region’s Tribes. Upstream are the Klamath Tribes in Oregon. And along the lower Klamath River in California are the Yurok, Karuk, Hoopa Valley, Quartz Valley Indian Community and the Resighini Rancheria."
