California Water Service Group acquires Nexus Water Group's Nevada and Oregon systems for $218 million, cementing its position as the largest regulated water utility in the western United States.
California Water Service Group marked its 100th year with a strategic expansion beyond California. The utility announced a $218 million deal to acquire water and wastewater systems in Nevada and Oregon from Nexus Water Group, adding roughly 36,000 connections and extending its footprint to seven western states
On February 25, 2026 - exactly one hundred years after three World War I veterans founded a small water company serving four California communities - California Water Service Group Chairman and CEO Martin A. Kropelnicki announced a deal that would add two more western states to the company's footprint. The symmetry was not lost on him. "This is a great way to kick off our centennial year," Kropelnicki said. "We started out serving four small California communities in 1926, and with this acquisition, we will serve roughly two million people through approximately 584,000 service connections in seven western states."
The acquisition, priced at approximately $218 million subject to closing adjustments, involves the Nevada and Oregon water and wastewater systems of Nexus Water Group - a Texas-based private utility operator headquartered in Sugar Land. The acquired systems encompass roughly 36,000 equivalent residential connections and carry a combined rate base of approximately $109 million as of December 31, 2025. The deal is expected to close by year-end 2026, pending approval from the applicable public utility commissions in Nevada and Oregon, and management expects it to be accretive to existing operations within one year of closing.
The Nevada systems are operated under Nexus's Great Basin Water brand, which serves approximately 16,000 customers across six communities in the Reno and Las Vegas areas. The Oregon operations extend Cal Water's regulated presence into the Pacific Northwest for the first time. Combined, the two state operations add 16 utility systems and roughly 115,000 people to Cal Water's service territory. The $218 million purchase price was funded entirely through existing working capital and debt and equity facilities - no new equity issuance required.
Baker McKenzie served as Cal Water's external legal counsel. The transaction was unanimously approved by the boards of both California Water Service Group and Nexus Water Group.
Nexus Water Group is a regulated, private water and wastewater utility with operations across North America including the United States and Canada. It operates in more than 20 states and multiple Canadian provinces through subsidiaries and branded utilities. In its Nevada operations, Nexus serves the Reno and Las Vegas areas through Great Basin Water. In Oregon, operations run under the SouthWest Water banner.
The sale to Cal Water is part of a systematic, coordinated divestiture strategy by Nexus CEO Rob MacLean. In May 2025, Nexus announced the sale of operations and assets in eight eastern states - Illinois, Indiana, Kentucky, Maryland, New Jersey, Pennsylvania, Tennessee, and Virginia - to American Water for $315 million, with closing expected by August 2026. The February 2026 California Water Service deal removed the Nevada and Oregon systems. What remains after these transactions is a leaner, geographically tighter Nexus focused on territories where, in MacLean's words, it is "better poised to grow and efficiently serve our customers."
MacLean was direct about the strategic rationale: "With this additional divestment, we are right sized and strategically positioned for continued growth." The Nexus approach - selling peripheral or scattered state operations to better-capitalized, regionally focused operators - represents a broader rationalization taking place across the American water utility sector. The 56 Nexus employees who operate the Nevada and Oregon systems will be offered employment by California Water Service Group following closing.
California Water Service Group is not the only water utility consolidating. The US water industry remains extraordinarily fragmented - more than 50,000 community water systems and approximately 14,000 wastewater treatment facilities operate across the country, the vast majority serving populations under 10,000. The American Society of Civil Engineers gave drinking water infrastructure a "C-" in its 2025 Infrastructure Report Card, while wastewater received a "D+." The EPA estimates the country needs roughly $1.26 trillion in water and wastewater infrastructure investment over the next 20 years to sustain existing systems and meet growing demand.
Smaller utilities, particularly those in rural or mid-sized communities, routinely lack the capital to finance modernization, upgrade aging pipelines, or address contamination threats like PFAS. That capital gap has become a structural opening for investor-owned utilities willing to absorb small systems, invest in infrastructure, and recover costs through regulated rate cases. According to analysts at Capstone, water utility consolidation is expected to expand through 2026, with larger firms including American Water Works and California Water Service Group among the primary beneficiaries.
The western geography is particularly strategic. Nevada and Oregon sit in water-stressed regions where the intersection of population growth, climate variability, and aging infrastructure creates persistent pressure on utility operators. The Las Vegas and Reno metro areas, which the Nexus Nevada systems serve, rely on water supplies subject to long-term scarcity concerns and increasingly contested allocation frameworks. For a capital-intensive regulated utility like Cal Water, acquiring established systems in such markets provides not just immediate accretion but a platform for future infrastructure investment that regulators are more likely to approve given the region's water urgency. Cal Water's own capital investment program is substantial: in 2025, the company deployed $517 million in infrastructure spending, a record representing roughly 20 percent growth over 2024 levels. Management has projected a further $1.6 billion in combined infrastructure and water quality investments through 2027, including major PFAS treatment expenditures. The Nevada and Oregon acquisitions add rate base and customer connections against which that capital can be deployed under regulatory frameworks in two new states.
The transaction price of $218 million represents approximately two times the acquired rate base of $109 million - broadly consistent with premiums paid in recent water utility acquisitions. The company's $2.78 billion market capitalization as of the announcement date places the deal at roughly 8 percent of enterprise value. Financing through existing facilities rather than a new equity raise avoids dilution and reflects Cal Water's assertion that it has sufficient balance sheet capacity to absorb the acquisition.
Management's expectation of accretion within one year of closing will hinge on regulatory outcomes in Nevada and Oregon - both require public utility commission approval for the change of control, standard in investor-owned utility transactions. Cal Water has recent experience navigating such processes: in December 2025 it received California Public Utilities Commission approval for its pending acquisition of Palm Mutual Water Company, a small system near Bakersfield. The company is also simultaneously pursuing full ownership of its Texas joint venture, BVRT Utility Holding Company, which operates seven water and wastewater utilities in the San Antonio and Austin areas. Taken together, these moves represent a concerted geographic and financial diversification away from reliance on California regulation for the majority of its rate base.
Cal Water's weaker Q4 2025 earnings - net income fell nearly 40 percent year-over-year to $11.5 million on lower water consumption driven by atmospheric river weather events in California - underscore why this diversification matters. A more distributed rate base across multiple state regulatory environments reduces exposure to weather, California rate case timing, and single-regulator decisions.
Not everyone celebrates the consolidation of water utilities into fewer, larger private hands. Consumer advocates and environmental groups have long argued that investor-owned water utilities prioritize shareholder returns over affordability, and that rate-of-return regulation too often lags behind capital recovery needs in ways that disadvantage lower-income customers.
The broader privatization debate is active and politically charged. In Gloucester Township, New Jersey, 81 percent of residents voted against selling their public sewer utility to New Jersey American Water in 2024, in defiance of a more than $1 million corporate campaign. Food and Water Watch and allied organizations argue that private water companies use the guarantee of a regulated return to extract profits from infrastructure that took generations of public investment to build.
For California Water Service Group's acquisitions of regulated private systems from another regulated private operator like Nexus, the privatization debate is less acute - these systems were already investor-owned before the deal. But the question of whether rate-setting commissions in Nevada and Oregon will quickly approve rates that allow Cal Water to earn its target returns on the $218 million invested is genuinely open. Regulatory lag - the gap between capital deployed and rates approved - is a persistent risk in this business model, and one that explains why management's one-year accretion target is explicitly conditioned on closing, not on immediate rate recovery.
The story of California Water Service Group is, in one sense, the story of what happens when patient capital is applied to an essential service in a growing but resource-constrained region. Founded in 1926 by three veterans determined to serve communities they had returned home to build, the company spent its first seven decades focused almost entirely on California. It began its multi-state expansion in 1997 when it formed a holding company structure to reach into New Mexico, Hawaii, Washington, and eventually Texas. The Nevada and Oregon acquisition closes one chapter and opens another. Cal Water is now the largest regulated water utility in the western United States by connection count. It serves roughly two million people - a scale that, a century ago, would have seemed unimaginable to the founders drawing water for four small California towns. Whether the next hundred years produce more consolidation, tighter regulation, or some new model for delivering water to a water-scarce West remains unresolved. What is certain is that the infrastructure problem is not going away. The pipes are aging, the aquifers are stressed, and the EPA's $1.26 trillion estimate for needed investment will not fund itself. In that environment, companies with the capital, the regulatory relationships, and the operational scale to absorb that investment are likely to find no shortage of systems willing to be acquired.
