At the end of 2025, Fort Collins’ City Council adopted the Water Demand Calculator (WDC) for calculating peak water demand and designing better plumbing systems for multi-unit residential housing, which is effective on April 1, 2026. The new code requires all housing, 3 or more units, to use the WDC (other types of housing may use it as an approved alternative). The WDC is part of the Uniform Plumbing Code and was created to account for the decades’ long improvements to water efficiency, which have resulted in lower peak demand and smaller piping needs. Right-sizing piping results in less water and energy waste, and less material costs.
