Public health assurance through effective wastewater treatment system design is a primary area of expertise. Navarro & Wright brings a variety of engineering experience and expertise to any job. Having worked with numerous municipalities and private-sector clients, our expertise has evolved—as has the field of sanitary engineering into environmental engineering, encompassing the management of air pollution, solid waste, and hazardous substances; along with drinking water, wastewater, and stormwater.

We provide evaluation, design and construction services for interceptor and lateral sewer lines, pumping stations, wastewater treatment facilities and optimization of existing facilities.
