The Weekly Dive #13
You can now harvest up to 2.5 gallons of alkaline water from the air at home. TidalWatt's underwater turbines are 60x smaller and produce 3x as much energy as wind turbines. The water industry cannot ignore digitisation and we explore why. Industry experts share their views on the water-tech investment landscape in 2023. Sea sponges and marine bacterias could help us fight COVID. This week, we are highlighting David Katzev, one of HydroDAO's key advisors. Learn about his impressive background and why he is passionate about water.
Your weekly Bonus - What do the new PFAS restrictions mean for 2023?
This week's quote:
“From birth, men and women carry the
weight of gravity on their shoulders.
They are bolted to the earth.
But they have only to sink beneath the
surface of the sea and they are free.”
- Jacques Yves Cousteau

The compounds found are effective against several variants including delta and omicron.
Agronomist checked whether hydrogels can save agriculture from water shortage
It turned out that this approach is unlikely to help save agriculture from drought.
David is a senior civil engineer at the East Bay Municipal Utility District (EBMUD). EBMUD is a California public utility that supplies high-quality drinking water, generates renewable energy and provides wastewater treatment and pollution prevention services that protect San Francisco Bay.
Through a system of pipes and facilities, EBMUD supplies Sierra mountain water to 1.4 million East Bay customers. EBMUD's water service area spans 332-square miles in Alameda and Contra Costa counties, extending from Crockett in the north, southward to San Lorenzo, eastward from San Francisco Bay to Walnut Creek, and south through the San Ramon Valley.
For more than 50 years, EBMUD has helped protect public health and San Francisco Bay with wastewater treatment and innovative pollution protection programs. The wastewater system serves approximately 685,000 people in an 88-square-mile area along the east shore of the bay.
Thank you David for your work and leadership in bringing clean drinking water to our communities.
