About US3
Utility Systems Science & Software is a specialized sewer flow data services firm based in Santa Ana, California, serving clients nationwide since 2002.
Company Experience
Utility monitoring built around field data and engineering review
US3 combines field instrumentation, telemetry, reporting, and engineering support for sewer flow monitoring and utility data programs.
What US3 Does
US3 exists to answer one question for engineers, municipalities, and developers: does this sewer system have the capacity to handle the flows being put into it? We answer with measured field data — not assumptions — sealed with a licensed Professional Engineer's stamp.
Our practice is built around collecting, validating, and delivering high-quality sewer flow monitoring data. We do not build models, design infrastructure, or manage construction. This focused scope means our clients receive data services from specialists, not generalists.
