UC Davis CWEE Accelerates Water Conservation Research with Secure, Compliant Data Storage on AWS

To solve some of the most pressing water and energy challenges, scientists and engineers need access to robust, reliable data that is often sensitive and protected. Data providers, researchers, and host institutions need to adhere to strict requirements for protecting and securing this data. The Center for Water-Energy Efficiency (CWEE) at the University of California, Davis (UC Davis) used Amazon Web Services (AWS) to create a centralized, secure data repository that streamlines data sharing.

Researchers at CWEE quantify how much energy is used in various elements of the water sector, including potable water, irrigation, and wastewater. This research helps water utilities, energy utilities, and policy makers decide how to invest in and promote water use efficiency, energy efficiency, and electric load shifting in the water sector. This research is critical particularly in California, where drought and other climate change outcomes, like heat waves and forest fires, have been an issue for decades and are growing more severe.

CWEE’s research heavily depends on large amounts of data that must be used in compliance with data privacy requirements. To date, data acquisition has been a largely manual process with strict security agreements and standards that can make it challenging to obtain.

To overcome these challenges, Dr. Frank Loge, director of CWEE and a professor in the UC Davis Civil and Environmental Engineering department, worked with UC Davis’s information technology departments to develop a new secure, shared system using a range of AWS services. The new system protects sensitive research data, makes clear who is responsible for protecting it, and verifies compliance. The system has garnered new interest and funding opportunities and has the potential to help spur new innovations in the water sector, driven by broad access to data.

How Water Conservation can Help Save Energy, Too

Watering the lawn less, taking shorter showers, and switching to a low-flow toilet all conserve water. And they also reduce carbon pollution. “About 20% of the state of California’s energy use is associated with the water system,” says Frank Loge of the University of California, Davis.

He explains that every step of a water system uses energy: pumping water from lakes and reservoirs, treating it to make it safe to drink, and pumping it into homes and businesses. Then, if it’s sent down a sink or toilet, it’s usually processed at a wastewater treatment plant, which Loge says takes a tremendous amount of energy.

Is California Ready for Brown Lawns and Shorter Showers? Drought Requires Less Water Use

In the face of rapidly worsening drought conditions this week, Gov. Gavin Newsom urged all Californians to voluntarily cut their water usage by 15% — but what exactly does that mean for the average California household?

The governor made his plea Thursday as he extended a regional state of drought emergency to 50 counties, comprising about 42% of the state’s population. For many, the talk of water reductions reminded them of the shriveled lawns, attenuated showers and water-bucket toilet flushing of the last devastating drought.

It also prompted some to wonder just how much more water Californians can conserve, since they continue to use substantially less water than they did before the 2012-2016 drought.

U.S. West faces little-known effect of raging wildfires: contaminated water

Early this spring, water bills arrived with notes urging Fort Collins Utilities customers to conserve. The Colorado customers may have thought the issue was persistent drought in the U.S. West.

But the problem was not the quantity of water available. It was the quality.

Utilities are increasingly paying attention to a little-known impact of large-scale fires: water contamination.

Huge forest fires last year denuded vast areas of Colorado’s mountains and left them covered in ash – ash that with sediment has since been washed by rains into the Cache la Poudre River. The river is one of two sources for household water in this college town of 165,000. With more and fiercer storms expected this year, officials worry about water quality worsening beyond what treatment systems can handle.
