RMWEA History

RMWEA was founded in 1936 as the Rocky Mountain Sewage Works Association and has since provided its members with the most current information on water quality issues, technology, regulatory changes, and the latest research developments.  We have published a calendar with photos of facilities from our three-state region for the last thirteen years.

RMWEA is celebrating its 90th Anniversary in 2026! See how we're marking the milestone.

RMWEA reserves the right to make the final photo selection and to publish the photos in the 2027 calendar or on the RMWEA website. A panel of RMWEA members will judge the photos, and the top-ranked pictures will be included in the 2027 Calendar.
