Specialty infrastructure engineering
WillCo Engineering is a specialty firm focused on utility infrastructure for projects without reliable municipal water and sewer service.
Founded and led by Eric Williams, P.E., the firm provides owner-focused engineering for commercial wastewater, decentralized treatment, public and private water supply, reclaimed water, lift stations, fire-water infrastructure, and related permitting.
Experience
Practical engineering across more than 2,500 projects.
WillCo’s experience ranges from individual commercial OSSF systems to RV resorts, industrial and high-strength wastewater applications, small wastewater facilities, public water systems, fire-water studies, and large rural infrastructure projects.
The firm regularly works with owners, developers, civil engineers, architects, contractors, manufacturers, operators, county authorities, TCEQ staff, and local fire officials.

How the firm works
Specialized support without competing with the civil team.
WillCo complements owners and civil engineering firms by handling specialized water, wastewater, reuse, fire-water, and permitting assignments. The firm does not position itself as a traditional land-development civil consultant; instead, it coordinates closely with the project civil team so utility decisions are resolved early and incorporated into the overall site plan.
