Hydrological Study

Optimize project site layout, streamline permitting, and mitigate stormwater management risks with early insights and advanced modeling.


As solar projects expand into more complex terrains, hydrologic and hydraulic analysis is vital to overcome challenges and unlock project value. From regulatory compliance to land optimization, ORCaS Hydrological Studies help you develop smarter, faster, and more sustainable solar projects — delivering exceptional value while staying on time and within budget.

Prevent environmental damage

Control pollutants like turbidity and suspended solids from entering downstream waterways. Protect ecosystems and meet strict environmental regulations.

Streamline permitting

Satisfy AHJ standards early to reduce permitting delays, avoid costly design revisions, and accelerate project approval.

Maximize land utilization

Accurately size stormwater basins to allocate more land to power production, improving project economics.

Improve construction planning

Understand hydrologic variables that impact construction staging, timelines, and site preparation, minimizing surprises during execution.

Reduce costs and risks

Avoid late-stage redesigns and unforeseen expenses by addressing hydraulic complexities upfront.

Deliver precision and confidence

Leverage high-fidelity data, automated analysis, and cutting-edge hydrologic modeling to generate actionable insights for your project, before breaking ground.

We provide rapid and flexible hydrological studies – from streamlined delineation of construction-phase sedimentation basins through comprehensive reviews that incorporate local environmental and regulatory constraints – and we partner with teams in the solar industry and beyond.
