EFFECTIVE APRIL 1, 2026 - WATER DEMAND CALCULATOR TO REDUCE WATER, ENERGY, AND CONSTRUCTION MATERIAL COSTS

Join us for an online training on March 24 from 12-1pm to learn about the Water Demand Calculator (WDC), which will be effective on April 1.  This training is for plumbing design professionals and others in the building industry. Please register for the event HERE to gain access to the event and the recording.

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. Here is more information and to download the calculator: https://iapmo.org/we-stand/water-demand-calculator (it is recommended that you download the calculator prior to the training).
