What EPD Consultants does

EPD Consultants, Inc. is a privately held civil and environmental engineering consulting firm founded in 1998 and headquartered at 20722 Main St, Carson, California. The firm delivers engineering design services narrowly focused on water-related infrastructure, including on-site wastewater treatment systems, graywater reuse, stormwater capture and use, low impact development, grading and drainage, erosion control, bridges, pumping systems, and hydrologic studies. Project work spans residential, commercial, and municipal clients throughout Southern California and includes LEED-Platinum certified water reuse installations (NRDC Santa Monica, Audubon Nature Center) and remote-site decentralized wastewater systems (Big River Elementary School, 7,000 gpd capacity).

Operationally, EPD runs a sales-led, project-based professional services model with no publicly disclosed pricing. Engagements are scoped per project and cover engineering design, project management, construction management, quality control/assurance, and permit processing across city, state, federal, and coastal authorities, with explicit expertise in California Title 22 unrestricted non-potable reuse standards. The firm generates revenue from engineering consultancy fees and extends delivery through EPD Construction, a bonded and insured subsidiary holding C-42 Septic Contractors and B General Contractors licenses that provides turnkey onsite wastewater system installation, inspection, repair, and manufacturer-certified maintenance. The company is privately held, with no disclosed external investors, parent entity, or funding history.

Regional players

• Dudek: California-based environmental and engineering firm with strong municipal water, wastewater, and stormwater capabilities. Direct competitor for SoCal municipal RFPs that EPD also pursues.
• Hilton Farnkopf & Hobson (HF&H Consultants): California-based environmental and water resources engineering firm serving municipalities on water reuse, wastewater, and stormwater programs. Direct regional peer for SoCal municipal RFPs.

Direct peers

• Brown and Caldwell: Environmental and water-focused engineering consulting firm serving municipal and industrial clients across the U.S. Highly comparable to EPD's water/wastewater and reuse design practice, though at substantially larger scale.
• Civil & Environmental Consultants (CEC): Mid-sized civil and environmental engineering firm providing site development, water resources, and wastewater services to public and private clients. Closely matches EPD's combined civil + environmental offering at comparable scale.
• Carollo Engineers: Specialist water and wastewater engineering firm focused on treatment plant design, water reuse, and stormwater. Directly comparable to EPD's water/wastewater design core, again at much larger scale.
• Woodard & Curran: Environmental engineering and operations firm specializing in water, wastewater, and stormwater for municipalities. Comparable service mix to EPD with design + operations offerings.
• Kennedy Jenks Consultants: Employee-owned environmental and engineering firm focused on water, wastewater, and stormwater for municipalities. Closely aligned with EPD's public-sector water focus.

Broad incumbents

• Michael Baker International: Large multi-disciplinary engineering firm with water resources, wastewater, and stormwater practices serving public-sector clients. Overlaps with EPD's public infrastructure engineering services.
• AECOM: Global infrastructure consulting firm with a major water and environment practice. Overlaps with EPD on large municipal water reuse, stormwater, and wastewater programs.
• Stantec: Global engineering, architecture, and environmental services firm with significant water practice. Competes with EPD for municipal water/wastewater work at the upper end of project size.
