Aurora is planning an expansion to its innovative Prairie Waters project with the help of a $5 million federal grant, a project that city staffers say could recover enough water to support thousands of homes. The grant, which the federal government says the city is likely to receive, would be used toward the $11.5 million undertaking of digging a new pump station and radial well, which would draw water from below the South Platte River.
“Drought has been something we’re needing to tackle and handle more and more as the years go on, and so having this resource come from the South Platte instead of the mountains is definitely a drought resiliency component,” said Aurora Water staffer Justin Montes, who applied for the federal grant…
Radial wells consist of a single vertical shaft ending in multiple horizontal shafts that radiate outward like the spokes of a wheel. The radial well and pump station would be part of an expansion to the Prairie Waters project including another radial well that the city plans to dig in 2024. Aurora Water representatives say the entire expansion has the potential to double the water recovered by the project, which uses wells dug near the South Platte River to collect water that has been absorbed and naturally filtered by the riverbank. By the time water is collected by the wells, it has already passed through hundreds of feet of sediment beneath the South Platte, filtering out pathogens, organic chemicals and other contaminants. Montes said the process can also filter out debris introduced by wildfires.
