# Container rainwater storage

Replaced the exposed rainwater cylinders with a dark-green 20-foot container-style enclosure at the existing water-service area. Water is stored in two separate sealed internal tanks; the steel container shell is not used as the water-retaining vessel. Added cargo door hardware, corrugations, support piers, manifold/plumbing concepts, pump and first-flush component, and a west inspection cutaway. Kept the east cargo-door approach clear. Updated chapter 13 while preserving the 30-chapter tour and all other approved features.

Verified both tanks fit inside the container bounds, old exposed-tank objects are absent, all captions match, the kitchen and no-table-tennis decision remain intact, and full render settings remain 2560 × 1440. Inspected actual Cycles exterior and cutaway renders.
