Tres Rios Consulting Engineers provides Arizona-licensed engineering services for clients throughout the state. Our mission is to provide professional civil engineering planning, design, and permitting of public water supply, sanitary sewer, and solid waste systems.

We can assist with conceptual planning of new water supply systems, like evaluating groundwater sources or estimating system demands and growth. Often, we’ve assisted water system owners to evaluate several options for production well blending or treatment of sources that are impacted with arsenic, nitrates, fluoride, or TDS. Our engineers will design the final water production well site and treatment system, then help our clients to obtain the Approval To Construct permit.

Tres Rios’ engineers have designed gravity sewers, force mains, and lift stations to help clients with connecting to an existing City or Private wastewater utility. We can assist with project planning and preliminary design, detailed design of the construction documents, and assist with some bidding and construction phase services.

Our engineers have design and permitting experience with numerous state and federal agencies including ADEQ, Maricopa County, the City of Phoenix, the Corps of Engineers, Luke Air Force Base, and others.

We would be pleased to help you design your next water or wastewater project..
