This year, Newsweek recognized the top 850 companies across 28 countries for their environmental sustainability performance; Group is one of only two water utilities on the 2026 list. Newsweek developed the ranking in partnership with statistics portal and industry ranking provider Plant-A Insights Group and GIST Impact.

The methodology compared both public and private companies with more than 500 employees globally against minimum sustainability standards set by the European Union. Newsweek evaluated more than 25 parameters in four categories: greenhouse gas emissions, water usage, waste generation, and sustainability data disclosures and commitments. The ranking also analyzed companies' media coverage.

“At California Water Service Group, we take our role as environmental stewards seriously, and we continue to enhance our efforts to reduce our environmental footprint and protect our natural resources,” said Marty Kropelnicki, Group Chairman & CEO. “We appreciate Newsweek for recognizing us to be among the greenest companies worldwide.”

The event, from 3 to 6 p.m., will offer complimentary watercraft rentals, giveaways, anniversary treats, and family-friendly fun on the water. The celebration will take place at the Forebay Aquatic Center, 930 Garden Drive.

Founded in 1926 by three World War I veterans, Cal Water has grown from serving four California communities to serving more than 20 districts in the state, from Chico in the north down to the South Bay of Los Angeles. In Oroville, where Cal Water has provided high-quality water utility services since 1927, the company is celebrating a century of service by thanking customers and highlighting the local team's continued commitment to delivering safe, clean, reliable water.

"For nearly 100 years in Oroville, our team has worked every day to provide water customers can count on," said Loni Lind, Cal Water's Oroville Local Manager. "This celebration is our way of thanking customers for being part of our story and reaffirming our commitment to investing in the water system that supports everyday life, local businesses, and fire protection."

Cal Water customers are invited to stop by the Cal Water welcome table to check in, pick up a wristband for complimentary watercraft rentals, and learn more about water conservation programs, customer assistance resources, and other services available to customers. Giveaways and special anniversary treats will be available while supplies last. Customers are encouraged to RSVP for the event at: 100years.calwatergroup.com/events/oroville-district.

Watercraft rentals are complimentary for Cal Water customers and available on a first-come, first-served basis. Participants renting equipment will be required to complete a waiver onsite through the Forebay Aquatic Center; participants under 18 must have a parent or legal guardian sign the waiver, and proof of age may be required. Parking fees charged by California State Parks are not included.

Cal Water's Oroville District serves about 11,100 people through approximately 3,560 service connections. The local system includes 52 miles of pipeline, two storage tanks, six booster pumps, and four wells that supplement surface water from the west branch of the Feather River, which is processed at Cal Water's treatment plant.

The groundwater in some parts of the Central Valley, including the well serving Indianola Elementary, have unsafe levels of 1,2,3-trichloropropane-a contaminant commonly known as TCP-for drinking water. Cal Water, whose Selma service area is located about a mile from the school, had already treated its affected water sources for TCP using granular-activated carbon treatment years before. With Cal Water's Selma District delivering safe, clean water to its customers, Selma Unified secured a $3.2 million grant through the State Water Resources Control Board's Department of Financial Assistance and oversaw construction to connect Cal Water's system to the school. Self-Help Enterprises provided technical assistance on the project.

"Being able to partner with Selma Unified School District and Self-Help Enterprises to bring reliable access to safe, clean water to Indianola Elementary students, teachers, and staff is particularly meaningful," said Marty Kropelnicki, Cal Water Chairman and CEO. "Children should be able to focus on learning, and educators should be able to focus on teaching. Neither should be worrying about whether their water is safe."

"This project reflects Selma Unified's ongoing commitment to providing safe, high-quality learning environments for every student. We're grateful for the partnership with California Water Service and Self-Help Enterprises, whose collaboration helped make this important investment possible," said Selma Unified Superintendent Ed Gomes. "Most importantly, our students and staff can begin the school year knowing they have access to safe, reliable drinking water, allowing them to focus on what matters most-teaching, learning, and growing."

This project extended Cal Water's water main to connect 27 customers whose wells had gone dry. More than $1.3 million in funding was secured for the project through a direct allocation of the County's American Recovery Plan Act (ARPA) funding and DWR's Small Community Drought Relief Program to the County of Tulare. With the grant, crews installed 2,265 feet of 8-inch pipe and 335 feet of 12-inch pipe to connect the underserved community to Cal Water's Visalia District. Five fire hydrants were also installed to improve fire protection in the area.

"We believe that everyone should have access to safe, clean, reliable water, yet we know that's not a reality for too many communities right here in California," said Marty Kropelnicki, Cal Water Chairman and CEO. "We are pleased that, through this partnership with Tulare County, DWR, and Self-Help Enterprises, residents along Harrison Road can now have the dependable supply of safe, reliable water they need."

The County of Tulare committed significant ARPA funding to address long-standing drinking water challenges in its communities. "This project was denied previous drought funding, and households have continued to receive hauled and bottled water for several years," said Pete Vander Poel, County of Tulare District 2 Supervisor. "The County leveraged ARPA funds against new drought funding provided by DWR. This project is a prime example of state and local government working together to improve access to clean, affordable drinking water for communities that need it most."

"DWR believes every community should have access to reliable water for drinking, irrigating, emergency, and recreation," said Sammy Naventhan, DWR Small Community Drought Relief Program Manager. "The resilience this community and our partners have shown on this project showcases what's possible when human right to water is at the forefront in an underserved region. DWR is proud to have worked with Self-Help Enterprises, the County of Tulare, and Cal Water to make this happen."

In Goshen, part of the Visalia District, crews are installing 4,500 feet of new 12-inch and eight-inch water main and six new fire hydrants. In north Visalia, crews recently completed the installation of 2,300 feet of eight and six-inch water main between West Prospect Avenue and West Harold Avenue, on North Turner Street, North Conyer Street, North Stevenson Street, and North Willis Street.

"Proactively replacing aging water main enables us to continue delivering a reliable supply of safe, clean water to the community and local first responders before that infrastructure becomes unreliable," said Stuart Skoglund, Interim Visalia District Manager. "We've proudly served our customers for a century, and infrastructure upgrades like this one allows us to continue providing quality, service, and value-both now and for future generations, as we look to the next 100 years."

Crews will be working Monday Through Friday, from 7:30 a.m. to 4 p.m., east of Highway 99 on Avenue 308, Willis Avenue, Harvest Avenue, Avenue 306, and Avenue 305 from Road 72 to Farr Road. The infrastructure upgrade is expected to be completed by September.

Crews will work to minimize any disruption to traffic. Temporary asphalt will be applied until permanent paving is completed, which can be up to 30 days after project completion.

The project is part of Cal Water's ongoing commitment to responsibly invest in and maintain critical water infrastructure. Proactive improvements such as this help reduce future service interruptions, enhance fire protection, and continue providing safe, clean, reliable drinking water to the community.

The project, which started this week and is expected to be completed in October, includes installation of approximately 2,700 feet of new eight-inch water main. Crews are working to install the new main on Gaither, Logan, Lee, and Stillman streets.

"Water infrastructure improvements like this help Cal Water continue to provide reliable service for customers' everyday needs, while supporting first responders' emergency needs to protect the communities we serve," said Mike Andrada, Cal Water's Selma District Operations Manager. "We appreciate customers' patience as we complete work that will help maintain safe, reliable service for customers, support firefighters, and benefit the community for decades to come."

Crews will perform the majority of work Monday through Friday, between 8 a.m. and 4:30 p.m. Some night or weekend construction may be required, and nearby customers will be notified when scheduled after-hours work is needed. Cal Water crews will make every effort to minimize traffic delays during construction.

After installation, crews will flush the water lines and test water quality samples before connecting individual water services to the new main. Temporary service interruptions will be required when customer services are connected and the new main is placed into service; however, customers will be notified before any planned shutdowns.

Temporary asphalt will be applied until permanent paving is completed, which can be up to 30 days after project completion. This waiting period allows the trench to fully compact, helping provide a smoother road surface.
