CASQA
Advancing Sustainable Infrastructure for California’s Complex Watersheds
At Ulteig, we specialize in the development and application of open-source hydrologic and hydraulic models, advanced data workflows, and watershed-scale planning strategies tailored to California’s regulatory landscape.
Our team of engineers, hydrologists, modelers, and environmental scientists partners with regional agencies and municipalities to meet MS4 and NPDES requirements, enhance water quality, and build data-driven, climate-resilient infrastructure.
We don’t just analyze flow: we help design the systems and strategies that move California forward.
How We Help:
- Regional hydrologic and hydraulic modeling
- Advanced watershed planning and calibration
- MS4 and NPDES compliance strategies
- Flow duration curve modeling for ungauged streams
- Dynamic dashboards and visualization platforms
- Regulatory support and permitting navigation
- Cloud-based simulation and data tools
