Access to clean drinking water is essential to public health, economic stability, and self governance. For tribal nations across the United States, water infrastructure is not just a technical issue. It reflects sovereignty, planning authority, and long-term responsibility to the community. When these systems are designed and implemented on tribal terms, they offer important lessons about partnership, durability, and respect for governance.
At Big Valley Rancheria in Lake County, California, the Big Valley Band of Pomo Indians has completed a water treatment system upgrade that reflects those principles. The project, developed in partnership with ATEC Water Systems, a subsidiary of public company Cadiz Inc., provides reliable infrastructure to meet the community’s water needs today and for years to come, while remaining fully under tribal ownership and control.
The facility treats up to 100 gallons per minute and serves approximately 1,400 residents. It filters contaminants including iron, manganese, ammonia, and corrosivity. While water contamination is common throughout California, the approach taken at Big Valley Rancheria reflects a locally driven solution rather than a one-size-fits-all system.
Infrastructure Designed for Longevity and Choice
Tribal governments routinely make infrastructure decisions that must balance performance, long-term adaptability, and alignment with community priorities. By choosing ATEC Water Systems, Big Valley Rancheria opted for a system that uses modular filtration vessels that allow treatment capacity and configuration to evolve over time without requiring a full rebuild.
This design supports flexibility and long-term planning. As water quality standards evolve or community needs shift, the system can be adapted using the same core infrastructure. According to Ben Ray III, CEO and Tribal Administrator for the Big Valley Band of Pomo Indians, the ability to address different contaminants using the same vessels was a key consideration in selecting the system.
The result is infrastructure that supports continuity while preserving future choice, an essential element of responsible governance.
Reliability as a Community Standard
Reliable water service is part of everyday life, supporting homes, schools, healthcare, and public facilities.
The ATEC system’s automated backwashing process allows filtration cycles to continue without interrupting water production. This design maintains consistent service while enabling operators to focus on oversight, monitoring, and long term system performance.
Lead operator Leon Fred has noted that the system runs so seamlessly that backwashing often goes unnoticed. That consistency builds operational confidence and strengthens trust in the system.
Water Governance and Sovereignty
For the Big Valley Band of Pomo Indians, the water treatment facility is more than a utility upgrade. It is an expression of water sovereignty. Maintaining ownership and operational authority over water systems allows the tribe to govern essential resources according to its own priorities and values.
Tribal Chairman Flaman McCloud Jr. has emphasized that sovereignty extends to water infrastructure, reinforcing the tribe’s ability to plan, invest, and manage resources for the benefit of present and future generations. The completed facility now functions as a permanent piece of public infrastructure supporting residential use, community facilities, and long range planning at the Rancheria.
A Partnership Model Grounded in Respect
Through its ATEC Water Systems platform, Cadiz Inc. has worked with multiple tribal communities since 2008, focusing on groundwater treatment systems tailored to local conditions and community goals. At Big Valley Rancheria, the partnership reflects a model rooted in collaboration rather than substitution, supporting tribal leadership rather than replacing it.
The outcome is not defined by scale or spectacle. It is defined by durability, local control, and alignment with tribal governance. In a landscape where tribal water stories are often framed around crisis or scarcity, the Big Valley project offers a different perspective. It shows what is possible when infrastructure investment is guided by respect and partnership, recognizing that tribes are not merely filling a gap, but instead exercising capacity on their terms.
