Introduction to Expo Guadalajara and its Sustainability Efforts

Guadalajara, Jalisco. Expo Guadalajara, a prominent trade fair venue in Mexico, has recently unveiled an innovative rainwater harvesting system as part of its sustainability strategy. According to José Andrés Orendáin De Obeso, the president of Expo Guadalajara, this initiative positions the venue as the first in the country to adopt a sustainable approach.

The Rainwater Harvesting System

This groundbreaking project, which required an investment of three million pesos, comprises four cisterns capable of storing 100,000 liters of rainwater. This volume corresponds to the average daily water consumption for operations at the trade fair venue, primarily used for irrigation, sanitary facilities, and services.

Orendáin De Obeso explained that the system collects, stores, treats, and distributes rainwater for use in their facilities. The collected water is filtered and potabilized to ensure its quality for general purposes, with a pumping system leading the water to the main cistern.

The entire process is managed through a technological platform that enables monitoring and control of water distribution.

Complementary Sustainability Initiatives

Beyond the water efficiency aspect, Expo Guadalajara’s sustainability strategy also encompasses an energy efficiency system, set to be announced in August. Moreover, a sustainability program targeting the entire value chain—organizing committees, stand erectors, and other suppliers—is under development.

“This is a step towards a more responsible meetings industry while simultaneously addressing the pressing challenges of today,” Orendáin De Obeso stated.

International Recognition

Mario Silva, Head of the Tapatio Municipal Presidency’s Executive Office, highlighted that Expo Guadalajara is becoming an “international reference” for climate crisis adaptation practices and a model of hydrological resilience.

Silva pointed out that the metropolitan area generates approximately 16 million tons of CO2 annually, with Guadalajara municipality contributing 4.1 million tons—two million of which are related to energy consumption.

“Expo setting an example within the conventions and business tourism industry by implementing such measures is highly relevant, as it demonstrates to other economic activities in the city that economic activity and environmental protection can coexist,” Silva added.

Flood-Prone Area

Patricia Martínez Barba, Director of the Area Metropolitan Planning and Development Institute (Imeplan), mentioned that two flood-prone areas near the trade fair venue have been identified in the Unique Flood Map created by Imeplan.

“Nonetheless, this project is part of our adaptation to the challenges we face in the city; every drop of rainwater captured is water that can be utilized…We cannot fight against climate change; we need to adapt,” Barba emphasized.
