New Storm Water Infrastructure in Santiago, Nuevo Leon

Status: Completed


An area of the community of Los Fierros experiences frequent flooding during the rainy season due to the lack of adequate storm drainage infrastructure. The Municipality of Santiago is planning to construct infrastructure to collect, convey and discharge the storm water into an existing storm water collector, which discharges to a regional storm
water system managed by the Monterrey water utility, SADM. The existing system has sufficient capacity to receive the additional flow.


The project consists of constructing a new storm water collection main
along Benito Juarez Street and Tamaulipas Street to interconnect with
the existing regional storm water system and includes:

  • 1,089 ft. of 48-inch reinforced polystyrene pipeline.
  • 192.4 ft. of 86-inch reinforced polystyrene pipeline to carry
    storm water flows from Tamaulipas Street, under the federal
    highway, to a natural open drain.
  • One pentagonal reinforced concrete culvert.
  • Five reinforced concrete inlets with gratings.
  • One reinforced concrete transition manhole.


Improved storm water management will prevent unsanitary conditions, including flooding and surface ponding, thereby eliminating possible exposure to stagnant water and reducing the risk for waterborne diseases. In addition, the project will contribute to the conservation of natural resources by directing storm water flows to natural water bodies, thus creating opportunities for its beneficial use, as well as preventing dangerous erosion patterns caused by recurrent flooding. Finally, the project will also help protect private property and public infrastructure from recurring flood damage.
