Chinle, Arizona is a census designated area in the northeast section of the state located in Apache County.

The Navajo Nation is a Native American reservation located nearby in a northeast section of Arizona that also goes into parts of New Mexico and Utah. The Navajo Nation’s seat of government is based out of Window Rock, Arizona. Spanning 413 square miles, the Navajo Nation has the largest land area held by a federally recognized tribe in the U.S.

In the Navajo Nation, Chinle means “flowing out”, which refers to the water that flows out of the Canyon De Chelly. The population is around 4,500 while it connects to other parts of the region by U.S. Route 191.

Located to the east of Chinle is the Canyon De Chelly National Monument. This monument is managed by the Navajo Nation and the National Park Service. They collectively manage 84,000 acres. The National Monument was authorized in 1931 to preserve this canyon and surrounding areas. Various Native American people, including the Navajo and Pueblo Tribes, have resided in their ancestral homelands for thousands of years.

Canyon De Chelly features the Spider Rock spire which is about 800 feet tall within a surrounding canyon with sandstone cliffs. The Canyon De Chelly National Monument in Chinle, Arizona is an amazing place with scenic lookouts, hiking trails, tours, camping, welcome center, and drives.

This National Park Service required a lift station replacement. This was a “turnkey” project designed to meet commercial, municipal, and Navajo EPA standards for medium sewage flows.

Romtec Utilities was chosen as the single entity that could design, supply, and install this replacement lift station for the National Park Service (NPS), Navajo Tribal Utility Authority (NTUA), and White Dove, Inc.

These organizations preferred a single source with “site specific” expertise because of the remoteness of their location and the complexity of having three reviewing parties.

The design included chopper pumps in a duplex configuration, an inlet-line drop bowl, and a separate below-grade valve assembly.

The UL-listed control panel included primary and backup floats for level sensing, an auto dialer alarm, and a permanent on-site generator. It was designed with a shelter for the controls, and a crane was included on the top slab to pull and lower the pumps.

Romtec Utilities was able to meet NPS, NTUA, and Navajo Nation Environmental Protection Agency criteria for construction and pumping requirements. Utilizing Romtec Utilities as a single entity offered an incredible value for this package lift station and its installation. The group also was able to retain their existing lift station for emergency backup operation.

The replacement pump system featured a 6′ diameter wet well, 4″ discharge piping, Vaughan pumps, and a 4″ – 577 valve vault.

Romtec Utilities was pleased to be a part of this lift station replacement at the Canyon De Chelly National Monument in Chinle, Arizona.
