Overview
Water is simple. Water issues are complex. Legal is an important perspective in water matters but rarely the only one. That’s why we strategize with engineers, hydrologists, geologists, and water quality specialists to find solutions. Our team-oriented approach is one way we help clients resolve issues and deliver value.
We work daily to protect and secure long-term supplies of surface, ground, reclaimed, and desalinated water for members of the water industry and their customers. For more than 60 years, we have worked to preserve water rights, promote legislative interests, develop and finance essential infrastructure, recover costs of service, respond to regulatory initiatives and protect clients from potential liability.
We understand the unique California and federal laws and regulations that impact water from every possible perspective. We represent watermasters, water districts, cities, utilities, developers, agricultural growers and processors, design-builders, operators, and local, regional, and state agencies. We counsel them on a wide range of environmental, financing, water law, and water utility issues, including related litigation.
Our team includes an active Government Relations & Regulation practice in Sacramento and Washington, DC. They help clients achieve legislative and administrative solutions to the legal, environmental, and political barriers related to permitting, construction, development, and project approval. Working with our colleagues in the environment, land use, eminent domain, public finance, infrastructure, insurance recovery, and employment law arenas is crucial to serve our clients' diverse needs.
We are actively involved in advancing industry and professional organizations such as the Association of California Water Agencies, the California Water Association, the American Water Works Association, the American Groundwater Trust, the Water Education Foundation, the Groundwater Resources Association, and the Association of Ground Water Agencies.
Our attorneys and policy advisors provide timely and insightful updates on the water sector in California on our blog, California Water Views.

Successes
Successes
We obtained regulatory approval from the California Public Utilities Commission (CPUC) on behalf of the San Gabriel Valley Water Company so it could acquire the City of Montebello’s water system and associated assets.
After a challenging three-week federal court trial, we secured a $65 million jury verdict in favor of our public water agency client who had been involved in a 20-year legal battle with a polluter.
After a seven-year legal battle, we obtained a successful monetary settlement for our client, the Goleta Water District.
We achieved a successful result on behalf of both the buyer and seller of a California water company. We secured full approval from the CPUC—with amicable waivers obtained all around—and upheld state policy encouraging consolidation of smaller water systems.
We represented a water agency in a matter involving groundwater contamination.
On July 16, 2020, California’s Fourth Appellate District Court issued a published decision in favor of firm client Imperial Irrigation District (IID) in a dispute between a farmer in the district and IID over IID’s rights to Colorado River water. The published opinion can be found at Michael Abatti, et al. v. Imperial Irrigation District (2020 S.O.S. 3585).
We worked with leading California water associations to negotiate amendments to the recently adopted Waters of the State regulations to provide an exclusion for ongoing water supply and flood control related activities.
The California Public Utilities Commission voted to allow our client, California American Water Company, to proceed with its $322 million project.
We successfully represented a client in the first formal hearing involving a disputed starting allocation under California’s South Coast Air Basin’s emissions cap and trade program.
No stranger to the rough and tumble nature of California water disputes, we secured $50 million in water rights for an investor-owned water utility.
We used a multi-pronged approach to jump-start stalled water clean up efforts, which culminated in a $350 million contamination settlement.
We drew upon our water and public policy resources to prevent potable water from being regulated as a "waste" or "pollutant."
