We have completed projects across North and South America in all areas of water engineering. We have served expert witnesses for court cases involving flooding, pollution, leaks, and water rights. Some of our sample projects are summarized below

cabo rojo water filtration plant


Cabo Rojo Water Filtration Plant

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 Operation and Maintenance Services as well as designing the Raw Water Storage Tank for the plant in 2001.

Other Water Projects

  • Water System Hydraulic Analysis for Grove Landing Subdivision (Houston County, GA)
  • Water System Leak Analysis for the Puerto Rico Aqueduct and Sewer Authority (Cidra, PR)
  • Design Services for the Jimenez WFP Elimination Project (Rio Grande, PR)
  • Design of the Pasto Viejo Water Supply and Well Pumping System (Cayey, PR)
  • Water Supply System Design for Santa Ana del Yacuma (Bolivia)


Fort Allen Wastewater Treatment Plant

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.

Other Wastewater Projects

  • WWTP Assessment for Magen's Junction Apartments (St. Thomas, VI)
  • Construction Services for the Lajas Creek Crossing Sanitary Sewer (Lajas, PR)
  • Design of the Sewage Pump Station and Force Main for Riverside Town Center (Toa Baja, PR)
  • Improvements to the Sewage Pumping System for Barahona (Morovis, PR)

Runoff Management Analysis for the Yabucoa Agricultural Reserve

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.

Other Stormwater Projects

  • Hydrologic Analysis for SR 686 Pond 9 (Pinellas County, FL)
  • Sedgefield Subdivision Detention Pond Assessment (Paulding County, GA)
  • Review of the Stormwater Design Guidelines for Puerto Rico (Puerto Rico Planning Board)
  • SWPPP for Guaynabo Chalets (Guaynabo, PR)
  • Design of the Emergency Overflow Structure for Los Montes Residential Development (Dorado, PR)


Río Turabo Channelization

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

Other River Projects

  • Rio Descalabrado Bridge Scour Analysis (Coamo, PR)
  • Gotay Bridge HH Study (Jayuya, PR)
  • Bridge 150 PR-10 Scour Analysis (Utuado, PR)
  • LOMR-F for Las Primaveras development (Carolina, PR)
  • Rio Maniqui HH Study (Bolivia)


Sediment Transport Study of the Valenciano Reservoir

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.

Other Reservoir, Sediment, and Groundwater Projects

  • Sediment Transport Study for Rio Cayaguas (San Lorenzo, PR)
  • Design of the Hacienda de Lealtad Dam (Lares, PR)
  • Material Extraction Activity Study at Rio Cayaguas (San Lorenzo, PR)
  • Sediment Transport Study for Rio Grande de Manati (Manati, PR)
  • Groundwater Impact Assessment for Reina del Sur (Fajardo, PR)


Design of the Maricao Fish Hatchery

CA Engineering designed the upgrades to the Maricao Fish Hatchery, in a project funded by the Puerto Rico Department of Natural and Environmental Resources. We also provided Construction Inspection Services. Since its implementation, we have provided assessment and rehabilitation services.

Other Environment Projects

  • Water Quality Analysis for the Colewood Creek Watershed (Sandy Springs, GA)
  • Pool Stain Analysis for Parque De Las Fuentes Condominium (San Juan, PR)
  • Environmental Assessment for the Cayey Entrance and Information Center (Cayey, PR)
