In the flood-prone lowlands of Tanza, Navotas, infrastructure plays a critical role in protecting communities and livelihoods. The Tanza Dike, a longstanding barrier against rising tides and stormwater surges, was recently reinforced as part of a strategic drainage improvement initiative led by Calcon Engineering.

To meet the area's growing needs for a more durable and efficient drainage system, Profiled Wall Pipes—a form of Large-Diameter HDPE Pipes—were selected for their strength, flexibility, and resilience in tough environments. With a size of 800mm and a total length of 96 meters across 16 pieces, the installation focused on creating a gravity-fed system capable of withstanding both regular runoff and seasonal flooding.
