Colorado Springs has added nearly 100,000 water taps since 1980 and grown to about 500,000 residents, yet its water demand has moved in the opposite direction. Per-capita use fell 44% from 2000 to 2025, from roughly 139 gallons per person per day in the 1990s to about 73 gallons today, according to The Colorado Sun.
The figures measure different parts of the system. The per-capita number is an average for residents, while the reported 29% decline in citywide raw-water deliveries from 2000 to 2025 describes total utility volume. Together, they show that population growth has not translated into proportionally higher demand; they do not, by themselves, identify how much of the change came from household behavior, outdoor irrigation, efficiency programs or other factors.
The important precedent came before the latest grass conversions
Colorado Springs’ current landscaping work fits a policy direction documented more than a decade ago. The city’s 2014 Park System Master Plan recommended replacing bluegrass with less water-intensive grass species in lower-use park areas. The recommendation establishes an earlier planning precedent; it does not show that every later reduction in water use resulted from turf replacement.
The utility’s 2017 Integrated Water Resources Plan made a broader observation: after the 2002-2003 drought, population and water use no longer showed a clear correlation while per-capita use declined. That conclusion helps explain why customer growth and total demand should be tracked separately rather than treated as interchangeable measures.
A drought reset the city’s water assumptions
The 2002 drought was a major stress point for the system. Colorado Springs Utilities’ official history says an exceptionally dry and hot spring and summer pushed system storage to 42%, described as an all-time low in modern times. The later utility plan links the post-drought period with declining per-capita use, but the documents do not assign the decline to one policy or technology.
The latest park results provide one measurable part of that longer shift. Colorado Springs Parks and Recreation has converted 102 acres of Kentucky bluegrass to native grass species since 2012, according to reporting by The Colorado Sun and Rocky Mountain PBS. The reported savings differ by accounting period and category: the two outlets cite seasonal and 2025 totals that include water or maintenance costs. Those figures should therefore not be added together as a single cumulative total.
The pattern extends beyond one city, but comparisons have limits
Colorado’s lawn-replacement activity reflects a wider regional response to outdoor demand, though it is not evidence that other cities have achieved Colorado Springs’ results. Resource Central says participants in its separate Colorado program save an average of 15,000 gallons of water a year by replacing thirsty grass with water-wise landscapes. That is a program estimate for participating properties, not a citywide trend.
Colorado Springs’ experience therefore offers a narrower lesson than “growth no longer matters.” The documented record shows that the city has grown while average use and reported raw-water deliveries have declined, alongside a drought-era shift in planning and continued landscape conversion. What remains unresolved from the figures alone is how durable those savings will be as the population grows, and how much future demand will come from uses that lawn conservation cannot address.
