Who We Serve
Domestic, industrial, and Indigenous community water infrastructure — every engagement delivered personally by a senior P.Eng. with 36+ years of hands-on experience.
Municipal WWTPs, small community systems, collection systems and domestic PFAS compliance — serving communities from 500 residents to 1.2 million.
Twelve-plus industrial sectors covered — food & beverage, dairy, oil & gas, textiles, sugar refineries, pharmaceuticals, metal finishing, steel mills and landfill leachate.
First Nations water and wastewater infrastructure — robust, operable systems designed with the community, backed by training and long-term support.
What Makes BioTerraVa Different
BioTerraVa is not a conventional engineering firm. We combine senior P.Eng. delivery with patent-pending nano-technology and modular system solutions designed for real-world operability.
Four provisional patents in circular water and waste technology — ICEBT integrated chemical enhanced biological treatment and ANOC advanced nano oxidation composites — developed and validated for 90–99% contaminant removal.
Decades of applied research in nano-material engineering for pollution control, from the INNPT platform through to today's ICEBT and ANOC composites targeting organic, inorganic and heavy metal contaminants.
Every engagement is delivered personally by Medhat Gad, P.Eng., PMP® — a senior civil engineer with 36+ years of water, wastewater treatment, and reuse experience across 12+ industrial sectors and four countries.
Four available system modules to match your scale: 5,000 m³/d, 20,000 m³/d, 50,000 m³/d and a mobile truck-mounted unit at 30 m³ — designed for rapid deployment and minimal civil works.
Our Process
A transparent, four-stage engagement process designed for procurement officers, plant managers, and council decision-makers who need certainty on outcomes, timelines, and budgets.
Free 30-minute consultation to understand your facility, compliance pressures, and budget constraints. We identify the lowest-cost path to your outcome — often operational before capital.
Written proposal with defined deliverables, timeline, and fixed or hourly fee structure. Includes preliminary findings, regulatory pathway, and risk assessment — delivered within 3–5 business days.
Senior P.Eng. delivers every site visit, drawing, and submission personally. Regular progress updates, draft reports for review, and direct access to the engineer — no account-manager filter.
Final report stamped by P.Eng. under PEO Certificate of Authorization. Commissioning support, operator training, and 90-day post-delivery check-in included on every engagement.
