–PTAP- FRANCISCO WIESNER

The Francisco Wiesner Drinking Water Treatment Plant is the plant with the highest production capacity in Colombia and a fundamental part of the operation of the Drinking Water Supply System of the city of Bogotá, currently supplying 70% of the city’s demand – 6 million people – and several neighboring municipalities.

We expanded the treatment capacity from 14 to 21 m3 / s by building 8 new deep bed and constant rate filtration units.

Automation of the operation and maintenance processes of the filters and other main components of the treatment chain. Assembly of a new control center.

It reduces the vulnerability of Bogotá’s supply system, guarantees supply reliability and structurally improves the existing infrastructure.

Commissioning and start-up of electromechanical equipment, measurement, control, production and dosage of chemicals, with an approximate cost of 15 million USD.

Phases: Detailed engineering, construction, start-up and operation.

More than 16,000 m3 of concrete, used in the construction of hydraulic structures

EXPANSION OF THE WASTEWATER TREATMENT PLANT

–PTAR– EL SALITRE

The expansion and optimization of the Wastewater Treatment Plant, PTAR Salitre Phase II, is part of the Bogotá River Sanitation and Recovery Plan. This project, led by the Regional Autonomous Corporation of Cundinamarca (CAR), is of great importance for the community and the environment, since it will treat a volume of 7.0 m3 of water per second. It is decisive to achieve the decontamination of the Bogotá River.

PTAR El Salitre is the largest wastewater treatment project that has been carried out so far in Colombia.

The Biogas obtained from the thickening and stabilization through anaerobic digestion of the sludge extracted from the primary and secondary treatments, is used as fuel in the plant itself to generate 6 MW, equivalent to 40% of the operating demand.

The project will prevent an average of 450 tons of garbage per month from reaching the river and will reduce the contamination level of the tributary by approximately 90%.

In the construction of the project, around 1800 direct jobs from 8 nationalities have been created, 1.8 million m3 of excavations were generated, more than 200.000 m3 of concrete and 198 km of piles were used for the foundation of structures.

The Metropolitan Park is built on an area of 30 hectares, the active recreation space represents 7 hectares of the surface; the remainder will be used for vegetation and generate passive ecological recreation.

Around 2 million people from the towns of Suba and Engativá will benefit.

This project offers important benefits for the environment and human health, which will translate into a better quality of life for Bogotanos.

PTAR– SAN SILVESTRE

The San Silvestre WWTP project seeks to decontaminate the Magdalena River; the Miramar, San Silvestre and Juan Esteban swamps; to Las Camelias, Las Lavanderas, Pozo Siete and La Paz streams; and the San Silvestre, Palmira, San Judas and El Castillo wetlands, contaminated by the discharge of wastewater.
