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 help provide clean water for drinking, irrigation, and manufacturing through the design of water treatment and distribution systems. We study and work with water from its source to its destination. Our services include the analysis and design of:

  • Water Filtration and Treatment Plants
  • Water Distribution Systems
  • Water Intakes
  • Transmission Mains
  • Raw Water Storage Tanks
  • Clear Wells
  • Pump Stations
  • Well Pumps
  • Irrigation Design


We specialize in the design of wastewater treatment processes like activated sludge, rotating biological disks, attached growth bio-towers, continuous flow activated sludge and sequential bath reactors (SBR’s). We provide design services for:

  • Municipal Wastewater Treatment Plants
  • Industrial Wastewater Treatment Plants
  • Wastewater Collection Systems
  • Pump Stations
  • Force Mains
  • Infiltration and Inflow Studies
flood control


Flooding affects thousands every year. We help mitigate the effects of flooding by designing detention structures, road crossing structures, erosion control revetment for river banks, and drainage systems. We provide analysis, modeling, and design services in:

  • Surface Hydrology
  • Runoff Detention
  • Storm Drainage Systems
  • BMP/LID/GI implementation
  • Erosion, Sedimentation, and Pollution Control
  • Storm Water Pollution Prevention Plans (SWPPP, C-SWPPP)
  • Rainfall Measurement
  • Hydrologic Uncertainty Analysis and Heuristic Optimization
  • Floodplain and Floodway Management
  • 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 Studies
  • Letters of Map Revision (LOMR, CLOMR)
  • No-Rise Certifications
  • Sediment Transport Studies
  • Design of Bridges and Culverts
  • Scour Analyses
  • River Channelization
sediment transport


We perform watershed management studies through mathematical modeling and surveyed site information. We take advantage of GIS, LiDAR, and aerophotogrammetry when available to develop dam-beak and safe yield analyses of reservoirs in remote locations. We have performed 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
  • Groundwater Modeling


We strive to protect our water resources by going beyond the scope of engineering and delving into the areas of environmental science, limnology, and ecology. Our environmental expertise includes:

  • Environmental Compliance
  • Water Chemistry Studies
  • Water Quality Studies
  • Fish Passage and Life Preservation
  • Stream Restoration
  • Effects of flow on marine and plant life (Ecohydraulics)
  • Physical modeling of open channel flows
  • Fate and Transport Modeling
  • Wetland Delineation and Jurisdictional Determination
  • Plan Reviews
