In mid-October 2013, construction was finalized on the installation of 2,944 ft of new 36-in. ID storm and sanitary pipelines using pilot tube guided boring methods in Mexico City. The Subcolector San Marcos project, owned by La Comisión del Agua del Estado de México (CAEM), represents the first trenchless installation with this technique in Mexico. Akkerman Inc. was involved as the equipment supplier.
The Subcolector San Marcos project embodies the successful and accurate completion of the alignments, but more importantly, the culmination of several years of partnerships to educate, design, and procure equipment and pipe among many entities. Crews installed the 2,944-ft total in eight drives, ranging from 186 to 441 ft in length, from nine minimal depth and diameter shafts in the urban Plaza de Aragon, Ciudad Nezahualcóyotl municipality of Mexico City.
