Basic engineering, detailed engineering, structural engineering, and structural technical consulting were provided, as well as topographic and geotechnical studies and technical reports. The infrastructure project put out to bid involves the construction of a new wastewater treatment plant designed for an average flow rate of 8 m³/s, with the aim of improving the treatment of effluents before they are discharged into the sea.

To transport the raw effluent from the old treatment plant to the new site, a reinforced concrete pipeline with an internal diameter of 2.6 meters was planned, to be constructed as a tunnel, while the treated effluent will be transported through a similar pipeline, but an open-channel one, to be discharged at the pumping station that will feed the effluent into the subsea outfall, approximately 3 to 4 km offshore.

The project also calls for the demolition of the existing plant once construction is complete and the new plant is up and running.
