Arraijan y Burunga Panama
Arraijan, Panama
The Project
This sanitary sewer project, being constructed by the Panama Sanitation Program in the district of Arraiján Cabecera, aims to improve the sanitary and environmental conditions of the communities in this sector of Panamá Oeste Province through the construction of a wastewater collection, treatment, and final disposal system. Currently, wastewater is discharged without prior treatment into rivers and streams.
At present, the project is 52% complete. Work carried out includes earthmoving activities, pipeline installation, construction of inspection manholes, restoration work, and installation of residential service connections in areas near the Cáceres River and in communities within Arraiján Cabecera.
Supply Challenge
For this sanitary sewer project in Arraiján Cabecera, the primary supply challenge centered on the corrugated HDPE pipe requirements. The customer needed multiple non-standard lengths — 42” x 14.24’, 42” x 15’, 42” x 18.3’, 24” x 18.3’, and 24” x 14.24’ — in order to properly interface with the various precast chambers specified in the design.
The complication was that manufacturers typically produce this pipe in a single standard 20-foot length. Procuring the required dimensions was not simply a matter of ordering material; it required a coordinated technical and logistical solution.
AVEM Solution
At AVEM Water, we began by working closely with the project team to review the plans and perform a detailed material takeoff. From there, we helped identify each required pipe size and developed a clear allocation system so the contractor could easily track which pipe length corresponded to each chamber type in the field.
Leveraging our position as a major exporter of HDPE pipe, we negotiated a special production run with the factory to manufacture the specified custom lengths. In parallel, we structured the shipping plan to telescope the pipe efficiently, significantly reducing the number of containers required.
The result was a measurable cost benefit across the board — savings in material waste, reduced field labor adjustments, improved installation efficiency, and lower freight and logistics expenses.
