Water story
Supply constraint
2.7 hm3/yr recharge; -24.1 hm3/yr official availability.
Desal siting clue
Screen shallow coastal alluvium, then verify salinity.
Service risk
Tanks, pumps, aqueducts, and lift show who benefits.
Data behind the story
- CSL report facts are summary-level: 15 chemistry samples, 48 groundwater works, flow directions, static-depth ranges, and negative official availability.
- San Jose adds mapped chemistry, pumping tests, groundwater-flow arrows, static contours, and recharge/extraction zones.
- Surface-water context comes from MGN hydrography: named arroyos, arroyo wash polygons, canals, water bodies, vados, bordos, and presas.
- Infra layers show mapped assets and elevation context. Capacity, pipe losses, pump curves, stored volume, demand, and schedules are not in the raw GIS files.
- IMPLAN/PMD layers should become project overlays: green corridors, water-network extensions, aqueduct relocation, and colonia-level risk/service gaps.
