About Martinson Consulting Engineers

Direct work, clear ownership.

We design water and wastewater systems for communities across Colorado and the Mountain West, with ownership grounded in a focused practice and right-sized teams.

The Firm

A small firm, by design.

Martinson Consulting Engineers is a Colorado-based, multi-state licensed civil engineering firm specializing in water and wastewater infrastructure for small and mid-size communities across the Mountain West. We serve municipalities, districts, and private utilities with planning, design, and construction support services.

Our principal-led structure provides direct engineering oversight from scoping through startup. We stay lean by design and bring in proven specialty partners (structural, geotech, electrical and controls, process, surveying) when needed.

No handoffs. No internal silos. Direct accountability.

Best Fit For
  • Water/wastewater treatment, lift stations, pumping, and storage issues
  • Funding-driven projects (SRF, USDA RD)
  • Compliance-driven upgrades and CDPHE reviews
  • Owners who want a single point of contact and responsibility from scoping through startup

Our Approach

Three principles.

Field-driven design

We design from real operating conditions, not just calculations. Operators and field staff inform our design decisions.

Regulatory coordination

We coordinate early with CDPHE and local agencies so reviews stay efficient as requirements evolve.

Transparent communication

Direct access to the engineer leading the work. Status, risks, and tradeoffs in relatable language boards and operators can act on.

Nathan Martinson, PE

Founder & Principal

Nathan founded Martinson Consulting Engineers to deliver water and wastewater engineering with clear ownership from scoping through startup. He has nearly two decades of experience in the field, beginning with a Bachelor of Science in Civil Engineering from Colorado State University in 2006.

Before founding MCE, Nathan served as a team lead, project lead, and served as record engineer at established Mountain West consulting firms, leading treatment process design, conveyance, and owner’s advisor work for municipalities, special districts, and private utilities.

MCE was founded to bring that experience into a direct-oversight structure with no handoffs and clear lines of accountability. The firm focuses on funding readiness, CDPHE coordination, and compliance-driven upgrades for systems across Colorado and the Mountain West. Clients work directly with the principal from initial conversation through review and permitting, supported by a trusted network of specialized subconsultants and industry partners.
