Solar Site Drainage Screening
Identify watercourses, low points, runoff pathways and drainage-study requirements before layout development.

Why this workflow matters
Solar development changes surface roughness, access and concentrated flow paths even when panels are pile-mounted. Early drainage screening helps protect equipment, roads, receiving waters and downstream land.
Questions to answer
- Which water features intersect or border the site?
- Where does runoff enter and leave the boundary?
- Could roads or compounds block natural flow?
- What baseline and design storms are required?
Recommended workflow
- 1Map surface water, wetlands and terrain-derived flow context.
- 2Inspect low points, crossings and downstream receptors.
- 3Reserve preliminary drainage corridors and setbacks.
- 4Commission hydrology, infiltration and erosion studies for design.
Evidence to collect
- ✓ Watercourse and wetland mapping
- ✓ Topography and catchment boundaries
- ✓ Soil and infiltration data
- ✓ Local drainage standards and rainfall inputs
