Urban Storm Drainage Trujillo City

A safer future for 1 million people.

+ 11,000 hectares of a complex urban fabric and converging streams with a low coverage of rainwater services are the starting point for an integrated project.
Geotechnical team surveying the streams adjacent to the city to identify sites for the placement of sediment retention dams.
Helicopter equipped with LiDAR technology to survey 11 thousand hectares. The work required 6 days of flight, the marking of 10 thousand blades and more than 80 collaborators for the post-processing.

«The project provides an integral solution that will allow the city to face the onslaught of nature with a sustainable and resilient approach, reducing risks, damages and loss of assets, favoring the development of the community.»
Flooding in the city of Trujillo is a recurring problem, but it is about to be left behind thanks to the ARCC and Lombardi agreement, which will provide a comprehensive solution for the design of more than 100 kilometers of pipelines and 10 dams for sediment management, following the RIBA methodology and BIM management to ensure quality in execution and leave a legacy for the next generations of this wonderful city.

The city of Trujillo, the third largest city in Peru, located in the north of the country, in the department of La Libertad, has been affected over the years by floods of pluvial and torrential origin, mainly caused by the El Niño phenomenon.

These recurrent floods have caused devastating damage in several sectors of the city, which do not have the drainage infrastructure for the prevention and mitigation of rainfall risk, so this city has been developing in a disorderly manner repeatedly coexisting with floods that affect the welfare of the population, education, health, safety, trade and quality of life, which ultimately becomes an obstacle to development.

For this reason, the Authority for Reconstruction with Change (ARCC), carried out a Master Plan and a pre-investment study (Feasibility) to determine the integral solution to the problem, and thus provide protection to the population and the productive and service assets.

The project, with an estimated investment of US$125 million, has a structural component consisting of 10 sediment retention dikes, improvement of the hydraulic capacity of roads, more than 100 km of collectors, subcollectors, outfalls to the Moche River and the Pacific Ocean, sediment settlers, Sustainable Urban Drainage Systems (SUDS), coastal edge protection rockfill, as well as a non-structural component, which constitutes training in operation and maintenance.

Accordingly, for the preparation of the definitive studies and technical files for the project, which will benefit a population of more than 1 million people, LOMBARDI is developing an 18-month study, including all the basic studies of good technical practice, social and environmental studies and 2D-1D modeling of more than 9,000 urban hectares.
