CA Engineering provides services in all areas of water engineering. Our engineers are licensed in several states and proficient in industry-standard models and software. We do not shy away from a challenge and are used to solving complex water problems through a rigorous critical approach.



We are a leading expert in the design of water filtration plants and water distribution systems. We provide design services for:

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


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

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. 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


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). 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

We apply 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. 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


In addition to our water engineering expertise, we also provide services in environmental engineering. Our environmental expertise covers the realms of:

  • Environmental Compliance
  • Water Chemistry
  • Water Quality
  • Fish Passage and Life Preservation
  • Stream Restoration
  • Erosion, Sediment, and Pollution Control
  • Plan Review and Certification
