water-tower-original.glb is the unchanged downloaded original, 63,428 bytes.
water-tower.glb retains the source tank, steel bands, support legs and cross braces.
Project adaptations: remove the roof and horizontal lid, recolor galvanized steel,
and scale the same shared asset to the three former warehouse locations.
The adapted asset contains 994 triangles, compared with 1,158 in the original.
The reproducible adaptation script is tools/prepare-water-tower.py (Blender).

Three.js additions: concrete foundations, tank interior lining, open rim, mounted
night lamps, and water surfaces with small moving waves and animated normals.
The three water surfaces share one 2,240-triangle geometry and one material.
Water uses existing environment lighting; no extra scene-reflection render passes.
All running model data and code are local and work without internet access.
