San Antonio Heights sits on the northern edge of Upland with older single-story ranch homes built mostly between the 1940s and 1970s on larger lots that slope toward the San Gabriel Mountains. Many properties still have original galvanized or cast-iron lines that develop pinhole leaks after decades of mineral-rich water exposure. We map these lines using acoustic sensors and camera inspection without tearing up driveways or lawns common along 24th Street and Mountain Avenue.
Dry summers followed by occasional winter rains cause the clay-heavy soil to shrink and swell, shifting underground pipes especially on the steeper parcels near the wash. Access often means working around mature trees and narrow side yards typical of this neighborhood. We schedule most jobs during weekday mornings to avoid the heavier weekend traffic on Euclid Avenue and nearby Foothill Boulevard.

Leak Detection in Leak Detection in San Antonio Heights — Local Notes
- •Homes on the uphill side of 24th Street often have longer service lines that cross sloped lots, requiring extra listening points during acoustic scans.
- •San Antonio Heights properties near the San Antonio Wash experience more soil movement after winter rains, increasing the chance of joint separation on older copper lines.
- •Mature landscaping and narrow easements along Mountain Avenue limit equipment size, so we rely on compact correlators instead of larger trucks.
