Open Arsenal

Designed to Replace, Not Retrofit.

OpenHydrology is an open-source water infrastructure platform designed to rethink how clean water is created, managed, and shared. Instead of relying on proprietary filtration systems that remove everything and require ongoing replacement components, OpenHydrology focuses on selective purification, preserving beneficial minerals, and creating a transparent system that communities can understand, repair, and improve.

At its core, OpenHydrology uses modular electro-separation technology combined with advanced monitoring, automation, and mineral balancing to create a more natural approach to water treatment. The system is designed to remove unwanted contaminants such as salts, pharmaceuticals, industrial chemicals, heavy metals, and emerging pollutants while maintaining customizable water profiles inspired by natural spring systems. Users can configure mineral targets, including enhanced magnesium profiles, to create water chemistry suited for different environments and needs.

OpenHydrology is built as a fully open ecosystem with both hardware and software designed for modification and expansion. The platform includes modular treatment cells, open hardware designs, sensor systems, embedded controls, APIs, dashboards, and automation tools. Its decentralized architecture supports everything from individual homes and off-grid installations to community networks and municipal infrastructure, allowing local ownership and operation of critical water resources.

Artificial intelligence and automation are integrated to improve efficiency, reliability, and accessibility. OpenHydrology can provide predictive maintenance, contaminant modeling, treatment optimization, anomaly detection, digital twin simulations, and intelligent system recommendations while keeping control local and transparent. The platform is designed to help users understand their water systems rather than depend on hidden processes.

Beyond technology, OpenHydrology is built around an open-source community model. With transparent documentation, open manufacturing standards, shared research data, community-developed treatment profiles, and collaborative improvement workflows, the project aims to create a global ecosystem where individuals, researchers, engineers, and communities can contribute to the future of sustainable water infrastructure.
