Denver Water seeks permit for cost-saving sediment removal method

During the recent Water Policy Committee meeting held on July 17, 2025, in Aurora, Colorado, significant discussions centered around the Strontia Springs deep sediment removal project and its potential amendments. The committee reviewed an intergovernmental agreement amendment that could lead to substantial cost savings and environmental benefits for the community.

Matthew Allsopp, the source of supply superintendent, presented a new method for sediment removal known as facilitated flushing. This innovative approach utilizes the emergency reservoir draining system and a dredge pump to move sediment downstream, which could save Aurora approximately $1 million compared to the original mechanical dredging plan. However, the implementation of this method hinges on obtaining a permit from the Army Corps of Engineers, which may take an uncertain amount of time. If the permit is denied, the city would revert to the original plan, scheduled for 2029 to 2030.

The committee expressed support for pursuing the facilitated flushing alternative, recognizing its potential to enhance environmental management while reducing costs. The discussion highlighted the importance of efficient water management practices in maintaining the community's water resources.

In addition to the sediment removal project, the meeting also touched on the topic of "growth with intention," led by Alex Davis and Marshall Brown. This segment aimed to engage committee members in discussions about future growth strategies and their implications for water policy. The presenters emphasized the need for collaboration and input from council members to ensure that growth aligns with sustainable water management practices.

As Aurora continues to navigate its water policy challenges, the outcomes of this meeting reflect a commitment to innovative solutions and community involvement in decision-making processes. The next steps will involve pursuing the necessary permits and further discussions on growth strategies, ensuring that the city remains proactive in addressing its water needs.
