We have performed projects in the in the United States & territories (Puerto Rico, the Virgin Islands), and in South America (Bolivia). In addition to the sample projects listed below, we have also provided expert witness for court cases involving flood damages. Some representative sample projects include:


Cabo Rojo, Puerto Rico

Cabo Rojo Water Filtration Plant (1992)

CA Engineering designed the non-mechanical water filtration plant in Cabo Rojo, Puerto Rico for the Puerto Rico Aqueduct and Sewer Authority. Since its construction, we have continued to provide services for the plant, including designing the Raw Water Storage Tank for the plant in 2001.


Puerto Rico

Design of Multiple Wastewater Systems in Puerto Rico (1992-present)

Throughout our first 16 years in business, we have designed various sanitary systems for the Puerto Rico Aqueduct and Sewer Authority, including the Eulogio Reyes sanitary system, La Gonzalez Community sewer system, the Humacao Wastewater Treatment Plant and the Puerto Nuevo Wastewater Treatment Plant Sludge Pumping Station. We have also designed upgrades to the San Sebastian Wastewater Treatment Plant, and the Caguas Water Treatment Plant Intake. In addition, we have designed wastewater treatment plants for two Puerto Rico Army National Guard posts: Fort Allen and Camp Santiago. In the private sector, we have designed wastewater pump stations for multiple clients, including Johnson & Johnson.


Yabucoa, Puerto Rico

Runoff Management Analysis for the Yabucoa Agricultural Reserve (2017)

CA Engineering performed a hydrologic and hydraulic study for a 450-acre agricultural land immersed in the Rio Guayanés flood way. The project, part of the Regional Conservation Partnership Program funded by the Natural Resources Conservation Service (NRCS), consisted on designing the most expeditious way to drain the agricultural lands after a flood event in order to salvage the crops. Grass waterways and a parallel network of open channels were modeled and designed.


Caguas, Puerto Rico

Río Turabo Channelization (1997)

CA Engineering designed the channelization of the Turabo River to preserve conveyance, water surface elevations, and aquatic life passage in a contract with Raytheon.


Juncos, Puerto Rico

Sediment Transport Study of the Valenciano Reservoir (2007)

CA Engineering performed a hydrodynamic study of the Valenciano Reservoir in San Juan, Puerto Rico to determine the erosive effects within the reservoir bed caused from flow rate increases. This study included a hydraulic analysis of the upstream tributaries to the reservoir, as well as a hydrodynamic analysis of the reservoir itself. For this effort, we teamed up with Dr. Marcelo Garcia (University of Illinois), one of the leading sediment transport experts in the nation. This project was a sub-consulting work for CSA Group.


Maricao, Puerto Rico

Redesign of the Maricao Fish Hatchery (2003)

CA Engineering designed the upgrades to the Maricao Fish Hatchery, in a project funded by the Puerto Rico Department of Natural and Environmental Resources.
