Due to the rainy season, which sees 50 to 125 mm of rainfall per day, the trench was excavated section by section, laying the pipes and covering them before the rain could collapse the trench walls. Bedding material for the pipes came from nearby creeks and was manually shoveled onto tractor trailers, transported to the unloading point where it was manually unloaded, and wheeled to the trench. The works generally lasted until approximately 2:00 o’clock in the afternoon, until the rain would set in. An average installation rate of five pipes per day was achieved under these weather-restricted conditions and minimal use of machinery.
Thanks to a good construction team, Juan Pablo Cordon, who personally supervised the installation, and not least the HOBAS Site Expert who advised the team in optimally storing, transporting, manipulating and installing the products, the installation works were finalized to everyone’s content in September 2015. The pressure test was successfully conducted on October 24, and the hydropower plant went into service three days later, looking ahead to decades of green energy.
