How a Small District in Colorado is Leading The West in Water Innovation

In this episode of 21st Century Water, we sit down with Andrea Cole, General Manager of Dominion Water & Sanitation District in Colorado. With a background in engineering and law, Andrea brings a multidimensional perspective to leading water, wastewater, and stormwater efforts in the fast-growing Sterling Ranch community. We begin by exploring her journey from a small town in Wyoming, where an early appreciation for natural resources sparked her passion for water. Her unique blend of technical knowledge and legal expertise has positioned her to address the regulatory, financial, and political challenges that utilities face today.

We dive into Sterling Ranch’s model of sustainability, where renewable water is foundational—not an afterthought. Dominion, under Andrea's leadership, has helped position the community as a leader in water efficiency, achieving usage rates as low as 0.17 acre-feet per home annually. This mindset-first approach has shaped a culture where residents inherently value water as a finite resource. With only 10% of the community built out so far, Sterling Ranch is on track to grow to nearly 60,000 residents, with infrastructure in place to support long-term sustainability.

We also look at Douglas County’s broader vision for growth, where Dominion plays a central role in establishing renewable water systems to support future economic development. A key highlight is the $34 million regional wastewater treatment plant set to break ground, which will treat reusable water and enable indirect potable reuse. This project also connects a nearby disadvantaged community to modern infrastructure and safe water, correcting long-standing issues with non-renewable, contaminated sources.

Andrea emphasizes the importance of soft skills in leadership—stakeholder engagement, regulatory navigation, and political awareness—as often more critical than the technical engineering work itself. Her legal training enables her to view regulatory frameworks not as barriers but as tools for innovative problem-solving. We also discuss Dominion’s forward-thinking investment strategy, totaling over $70 million across wastewater, pump stations, and water pipeline projects in the coming years.

Despite being a small and growing utility with only 11 employees, Dominion is leveraging its flexibility to adopt modern technology like GIS to enhance planning and operations. Workforce development is another key theme, with Andrea focusing on hiring people who thrive in dynamic environments and want to help shape the district’s future. She closes by expressing her vision for a legacy rooted in sustainability—a future where our great-grandchildren can enjoy water and nature just as we have.
