CA Engineering provides services in all areas of water engineering. Since 1992, we have designed flood control structures, wastewater collection systems, wastewater treatment plants, water distribution systems, and water filtration plants in Puerto Rico, the Virgin Islands, the mainland U.S., and Bolivia. We have also performed hydrologic and hydraulic studies for a variety of purposes, including stormwater runoff mitigation, dam-break analysis, river channelization, drainage design, and scour analysis. Our engineers are licensed in several states, and our software development team has produced in-house software for a variety of purposes, including: detention pond design, pipe sizing, hydrograph generation, and sediment transport studies. A list of qualifications and expertise is found here. Our services include:

WATER

We are a leading expert in the design of water filtration plants and water distribution systems. Among our designs are non-mechanical water filtration plants such as the 2 MGD plant in Cabo Rojo, Puerto Rico and several conventional water filtration plants in Puerto Rico, the U.S. and abroad. Commercial software is used for modeling water distribution systems. We provide design services for:

  • Water Intakes
  • Filtration Plants
  • Water Distribution Systems
  • Transmission Mains
  • Storage Tanks
  • Pumping Stations

WASTEWATER

We specialize in the design of municipal wastewater treatment plants: activated sludge, rotating biological disks, attached growth bio-towers, and others, including the design of either continuous flow activated sludge or sequential bath reactors (SBR’s) for industrial facilities. We provide design services for:

  • Municipal Wastewater Treatment Plants
  • Industrial Wastewater Treatment Plants
  • Wastewater Collection Systems
  • Pump Stations
  • Force Mains

STORMWATER

We have vast knowledge of storm water management, sizing and designing single and interconnected storm water detention structures, sizing and designing road crossing structures, and designing erosion control revetment for river banks, as well as storm water collection systems. Additional services extend to the elaboration of Storm Water Pollution Prevention Plans (SWPPP),  in  compliance with  Section  402, 1987 amendments to the Clear Water Act. We have performed hundreds of hydrologic and hydraulic studies for the housing industry, including hydraulic analyses under steady and unsteady flow conditions. We apply the latest public, commercial, and in-house H&H modeling software to create one-, two-, and three-dimensional hydrodynamic models. Internationally, we have performed a Hydrologic and Hydraulic analysis for the Rio Maniqui located in the Bolivian Amazons. We provide analysis, modeling, and design services in:

  • Surface Hydrology
  • Runoff Detention
  • Storm Drainage Systems
  • Erosion Control
  • Storm Water Pollution Prevention Plans (SWPPP, C-SWPPP)
  • Rainfall Measurement
  • Floodplain and Floodway Management
  • Irrigation Design
  • Agricultural Land Preservation

RIVERS

We perform hydraulic studies to request Flood Insurance Rate Map (FIRM) revisions or amendments to FEMA in compliance with the National Flood Insurance Program (NFIP). We have performed tenths of river encroachment studies. We have performed copious sediment transport studies using USACE modeling software. We have designed a method of analysis to fulfill the local regulatory requirements for the control of sand extraction from the rivers of Puerto Rico. In time, this methodology has become the standard analysis followed by engineers and regulators in the island. Our services include:

  • 1D, 2D, and 3D Hydraulic Modeling
  • Encroachment Analysis
  • Letters of Map Revision (LOMR, CLOMR)
  • Sediment Transport Studies
  • Design of Bridges and Culverts
  • Erosion and Scour Protection
  • River Channelization

RESERVOIRS

We apply the latest public and commercial mathematical modeling technology to perform watershed management studies based on GIS, LIDAR, aerophotogrammetry or surveyed information, depending on the needs of the project. We have made Safe Yield Analyses for two major reservoirs in Puerto Rico: the Toa Vaca Reservoir and the Valenciano Reservoir. We perform H&H studies addressed to the design of flood control structures (dikes, levees, and detention basins). Our services include:

  • Safe Yield Analysis
  • Dam Level Analysis
  • Sequential Operation of a Reservoir-Channel
  • Scour and Deposition Analysis
  • Dam Break Modeling
  • Sand Extraction Permits
  • Reservoir Life Estimation

OTHER SERVICES

In addition to our water engineering expertise, we also provide services in environmental engineering and site/civil design, led by our environmental and civil engineers. Our environmental expertise covers the realms of:

  • Environmental Compliance
  • Water Chemistry
  • Water Quality
  • Fish Passage and Life Preservation
  • Stream Restoration

Our site/civil services include:

  • Preparation of Construction Sheets
  • Site Layout Design
  • Utility Design and Profiles
  • Erosion, Sediment, and Pollution Control
  • Plan Review and Certification
