Passage:
In traditional Ile-Ife residential architecture, the impluvium—a central courtyard designed with sloping roofs to collect rainwater—served as both a domestic water source and a micro-climate regulator. Recent municipal pipe network failures in the urban center have prompted contemporary architects to integrate modified impluvium systems into modern multi-story housing developments. Unlike synthetic storage tanks that exacerbate urban heat island effects through non-reflective surfaces, these subterranean brick cisterns rely on natural evaporation to cool surrounding living spaces while storing filtration-treated water. However, urban planners note that structural retrofitting requires precise load-bearing calculations, as the clay soils of the region expand significantly when saturated. Consequently, high-density residential developments in low-lying zones have largely opted for external pressure-sealed tanks, reserving impluvium integration primarily for sprawling low-rise layouts where spatial footprints permit gradual water dispersion.
Based on the passage above, evaluate whether the following statement is TRUE or FALSE:
The preference for external pressure-sealed tanks in high-density, low-lying developments is primarily driven by the structural risk of soil expansion beneath concentrated building loads.
