Water pipeline being staged for the San Juan Lateral.
By Damon Hill
The Navajo-Gallup Water Supply Project (NGWSP) includes 300 miles of pipeline, several pumping plants, and two water treatment plants that will bring a long-term sustainable water supply from the San Juan River to parts of the Navajo Nation, the Jicarilla Apache Nation, and the City of Gallup.
Currently, more than 40 percent of Navajo Nation households rely on hauling water to meet their daily needs, and their groundwater supply is rapidly depleting. Insufficient water also limits the ability of residents of the Jicarilla Apache Nation to live and work outside of the reservation town of Dulce. Lack of reliable drinking water has also had a profound effect on families and communities during the pandemic. The Bureau of Reclamation estimates that th... (more)

We're pleased to welcome Pamela Mugisha as an intern with our Puget Sound Water group! We asked her a few questions about her background, career, and goals.
Education: I got my bachelor’s degree in Agricultural engineering from Makerere University, Uganda. Then I got my Master’s degree in Hydroscience and engineering from Technical University Dresden in the Saxony state of Germany. Currently I am pursuing a PhD in Environmental engineering at Texas A&M in Kingsville, Texas.
Where did you grow up? I grew up in the capital of Uganda, Kampala. But my Village is Kisoro located at the South-West border of Uganda and Rwanda.
Why did you choose Parametrix for your internship? I chose an internship at Parametrix because I have learned quite a bit in school and would like to use my knowledge to make real-life impact and decisions in a ... (more)

The United States Environmental Protection Agency has announced that community water systems that serve more than 3,300 people are required to complete a risk and resilience assessment and develop an emergency response plan by June 30, 2021. (This is according to Section 2013 of America’s Water Infrastructure Act of 2018.) Are you prepared?
What is a Risk and Resilience Assessment?
According to the EPA, risk and resilience assessments “evaluate the vulnerabilities, threats and consequences from potential hazards.” These must be reviewed every five years and resubmitted to the EPA. They include elements such as natural hazards and malevolent acts; resilience of water source treatment, and distribution system infrastructure; monitoring practices; security and resilience of financial, electron...

Part 1: AFT Arrow
By Matt Steiner & Jen Murphy
Many utility ratepayers are currently struggling with economic security. At the same time, energy costs are rising and the impact of uncertain material and equipment markets is driving project costs up and making capital planning less predictable. As such, it is important that as engineers that we leverage all available tools to optimize each project’s capital and operational costs. Almost just as important is sharing what we learn with not only our colleagues, but the wider engineering community.
The Aeration systems at Resource Recovery Facilities (Wastewater Treatment Plants) account for 30 to 80 percent of a plant’s energy usage, making them typically the single largest source of energy use within the facility. They’re also the most complex and capital intensive systems within a plant. This integral system, which ... (more)

Clara Olson is a water engineer based out of our Portland, OR office who recently earned her Professional Engineer license. Learn more about Clara, the projects she’s worked on, and her advice for others taking the PE test.
Tell us about yourself.
I grew up in Portland and after four years of college in Spokane (Go Zags!) and two years in the Puyallup office, Portland was calling me home again. I’ve been back in Portland for over two years and couldn’t be happier. The Portland office was an easy transition and I love having the community in both Puyallup and Portland.
I love the outdoors and have been getting more and more into backpacking trips in the Pacific Northwest. This summer included a lot of hiking, camping, and backpacking! Mt. Rainier is one of my favorite places on earth and I was lucky enough to spend three different weekends in th... (more)

Parametrix wetland scientists delineating wetlands in Mason County, WA.
The final rule for defining waters of the United States (WOTUS) was approved in January 2020. The new rule eliminates Clean Water Act protections
for the majority of the nation's wetlands and more than 18% of streams, according to the US Geological Survey’s National Hydrology Dataset.
The Navigable Waters Protection Rule, also known as the Waters of the US, or WOTUS, rule, replaces regulations that have been in place since the Reagan administration.
