Quebrada Leon Flood Control Works

The first ARCC flood control project to be completed

$200 million+ saved on construction based on value engineering

Commissioned in March 2024, 2 years and 9 months after start of engineering

Challenges

The Peruvian government introduced a program to reduce recurring floor risks and damages caused by flash floods during El Niño events.
As part of this program, the Quebrada El Leon flood control project needed a partner to manage the conceptual designs, cost-benefit analyses, environmental permitting, and detailed engineering for construction.
The project had to account for public safety and navigate significant challenges including the impacts of climate change, flash floods, and areas with high seismicity.

Through value engineering, we proposed a design that virtually eliminates human intervention during operations, including a 20-km-long canal with low maintenance requirements, which avoids industrial, residential, and agricultural areas.
Planned for structures to avoid environmentally and archeologically sensitive areas to minimize overall impact to the environment.
Optimized the design with a focus on cost control, making efficient use of local materials to reduce costs by 50% compared to an alternative developed at a previous stage.
Commissioned in March 2024, the project focused on simple structures, local materials, and constructability aimed at a shorter construction schedule with a design that was considered unconventional in Peru.

Provided a design approximately half the cost of a previously developed option, which proved better for the environment, safer for the local communities, and simpler for a shorter construction schedule.
Delivered from the Hatch project office in Trujillo by an international team, bringing our Canadian team’s expertise in designing flood control structures with the support of our Latin American delivery team (Lima, Santiago, Medellin, and Belo Horizonte).
Successfully completed the project on a fast-track schedule with the approval of the ARCC on a Hatch design that was considered unconventional in Peru.
