Colombia Saves $18.6M, Secures Water for 1.4M Families

Engineers in Medellín, Colombia just cracked the code on making clean water more affordable and reliable for 1.4 million families, and the solution came from creating a virtual copy of their entire water system.

Empresas Públicas de Medellín (EPM) faced a common challenge: ensuring millions of people get clean water every day while keeping costs low. Their engineers spent weeks hunched over spreadsheets, manually calculating how water flowed through five treatment plants and hundreds of miles of pipes.

Then they built something revolutionary. Using OpenFlows Water software from Bentley Systems, EPM created a complete digital twin of their water network that could predict how the system would perform 30 years into the future.

The results stunned even the engineers. Tasks that once took months now finish in hours. The digital model revealed that Medellín could optimize its existing infrastructure instead of building costly expansions, saving $12 million in unnecessary construction.

But the savings kept adding up. The software identified energy inefficiencies in pumping stations that were wasting power every single day. By fixing these issues, EPM now saves 2,500 kilowatt hours daily, cutting $95,000 from annual energy bills and eliminating 117 tons of carbon emissions.

The digital twin does something even more valuable than saving money. It predicts how droughts and landslides will affect water delivery, allowing engineers to prevent service interruptions before families even notice a problem.

The Ripple Effect

The $18.6 million in total savings means EPM can keep water rates affordable while reinvesting in infrastructure that will serve generations. When utilities save money through smart technology instead of cutting corners, everyone wins.

The approach also shows other cities a path forward. Aging water systems worldwide struggle with the same challenges Medellín faced, and many respond by raising rates or delaying critical upgrades.

Clean water isn't just about turning on a tap. It's about kids staying healthy enough to attend school, parents working without water-borne illnesses, and communities thriving instead of just surviving.

Medellín proved that investing in digital innovation pays for itself many times over while making life better for millions of people at once.
