We worked on the executive project for the new wastewater treatment plant for the city of San Ramón. Our scope included the design in the areas of hydraulics, architecture, roads and electricity.

The plant was designed with a biological treatment of activated sludge with extended aeration. This process includes nutrient removal and final disinfection of the water with UV radiation. The treated effluent is discharged into the Santa Lucía River through an outfall. The sludge generated is collected and thickened in a satellite tank and then disposed of in drying beds.

The design of the WWTP considered both effluents from the city sewer system and from individual systems transported by barometric trucks. The main design parameters were:

• Average daily flow rate: 12 liters per second.
• Maximum instantaneous flow rate: 34 liters per second.
• Equivalent population: 5,000 inhabitants.

To develop the project, we use the BIM (Building Information Modeling) methodology. We modeled all disciplines, from civil and hydraulic infrastructure to architecture and concrete and metal structures. This technology allowed us to coordinate the project, improve visualization with the client and generate the necessary technical documentation. In addition, we delivered an integrated model viewer for a better understanding of the work.

This project allowed us to provide a complete and efficient solution for the sanitation of the city, contributing to the protection of the environment and the health of the community.
