Why One of Colombia’s Largest Wastewater Plants Trusts Rubber Check Valves

Proco Products, ABC Ingeniería supply new, 84-inch duckbill check valve to protect Medellín treatment plant

Boasting zero maintenance requirements and absolute protection against backflow, it is no wonder why one of Colombia’s largest wastewater treatment plants has trusted rubber duckbill check valves to protect the integrity of its operations for more than 20 years.

An 11-mgd facility in southern Medellín is one of Colombia’s most important. It is the largest wastewater treatment plant in the Aburrá Valley, an inland region of nearly 4 million residents shaped both physically and culturally by the health of the Medellín River. When an 84-inch-wide duckbill check valve capping an outfall pipe only a few feet above the river bottom began to show signs of age, securing a fast and reliable replacement for the valve became critical to the facility’s mission.

Proco Products, Inc., working alongside its Colombian distribution partner ABC Ingeniería, responded by sourcing a new ProFlex™ Style 711 Flanged Sloped Bottom Check Valve according to the facility’s specifications. The replacement valve, installed in April 2023, promises to safeguard the facility as well as the quality of the Medellín River for decades to come.
