About Us
Making Subsurface Intelligence Accessible
Passive Water Intelligence LLC was founded on a simple premise: every water district, dam owner, and mine operator deserves affordable, continuous subsurface monitoring.
Our Mission
We make continuous subsurface water intelligence affordable and accessible. Traditional monitoring methods require expensive drilling, periodic manual measurements, and leave dangerous blind spots between observation wells.
PWI deploys networks of passive sensors that capture mechanical response and other subsurface signal data — and extracts actionable intelligence about what's happening underground, continuously and spatially.
Our technology costs 10–100x less than conventional approaches, requires no drilling or permits, and delivers more information from a single sensor than an entire observation well network.
By the Numbers
Our Technology
Powered by PMRI
PWI is built on the PMRI (Passive Mechanical Response Inversion) analysis engine — a proprietary platform that extracts multiple independent subsurface data streams from passive sensors. Water monitoring, dam safety, geothermal, and environmental applications. Subscription-based SaaS model.
