In 2024, Hitachi Energy’s Halol transformer insulation and components factory in western India faced a unique challenge during the monsoon season, which ultimately turned into an opportunity for sustainability. Heavy rainfall caused waterlogging across the factory grounds, prompting the local team to envision a rainwater harvesting initiative to recharge local groundwater and align with the factory’s broader sustainability goals. Through this effort, the Halol factory achieved “water-positive” status, collecting more water than it consumed.
The project began with a thorough survey to assess the area and develop an artificial recharge structure to address waterlogging and groundwater depletion. The initiative aimed to reduce the factory’s dependence on external water sources, contribute to water conservation efforts, and ensure a sustainable future for the community.
While designing and implementing the rainwater harvesting system was not without its challenges, the results were impressive. During the monsoon season, the factory successfully recharged approximately 14,185 cubic meters of water back into the ground, exceeding its yearly water consumption. The initiative led to a rise in groundwater levels and an improvement in water quality, particularly in Total Dissolved Solids (TDS) levels.
The success of the project created a cultural shift in sustainability within the workforce, inspiring a greater sense of environmental consciousness. Employees are now more aware of their water usage and are adopting sustainable practices in their professional and personal lives. The project’s impact extends beyond the factory, serving as a model for sustainable practices and environmental stewardship. By turning a challenge into an opportunity, the Halol factory sets an example for organizations to prioritize sustainability and make a positive impact on the environment.
