Building a 2.0 MGD (Million Gallon Per Day) extended aeration biological nutrient removal wastewater treatment plant for the Navajo township is no small feat. Being able to execute at a high level 300 miles from both Phoenix and Albuquerque is the type of work we have become known for. Kayenta, Arizona is a land of contrasts. Rugged, remote, and unforgiving, it borders the iconic sandstone towers of Monument Valley, one of the most breathtaking landscapes in the West. Yet, ankle deep in mud, it’s not vacation scenery. Built on grit, legacy, and sacred ground, this project will stand and serve the township for the next 50+ years, crafted by a team that embodies the spirit of the Southwest.
Kayenta has a community with deep historical roots and a unique governance structure. Established on November 13, 1986, under the Navajo Nation, it remains the only township in the nation, managed by an elected five-member board and a manager. Historically, the area was inhabited by Ancestral Puebloans, who, due to environmental and social stresses in the late 1200s, migrated southward into various regions, including the Kayenta region, now part of northeastern Arizona and southeastern Utah. This migration led to the spread of their cultural influences across the southwestern United States. As of 2025, Kayenta's population is approximately 5,410.
This wastewater treatment plant represents long-term resilience for the township, protecting public health, preserving the surrounding land, and supporting a community with centuries of history behind it and generations ahead. When the equipment moves on, what remains is infrastructure built to endure; a reflection of the people it serves and the team that brought it to life.
