February 28,2020 - We recently updated the City's Stormwater Management Plan, which describes the Division's completed and future work. Members of the public can view the document and provide comments to City Staff by clicking the following links:

February 26, 2020 - The results are in! Last year eleven residents collected 773 lbs. of debris from local neighborhood storm drains through the City's inaugural Adopt a Drain Program! When added to the City's stormwater pollutant collection efforts, participating residents and City crews kept over 5,923 tons of debris from dumping into local waterways in 2019. That is equivalent to the weight of 456 full size school buses.

A huge thank you to those residents who participated and to the City crews working hard to make Bozeman a great place to live. Please click the link if you would like to learn more about adopting a drain in your neighborhood  - Adopt a Drain Program

October 3, 2019 - Please see below for a learning opportunity provided by the Montana Stormwater Committee.   



July 24, 2019 - We recently completed the City's first boulevard infiltration gallery near the intersection of W. Mason and S. Tracy. The facility captures and infiltrates stormwater runoff from two acres of nearby urban landscape, which would otherwise dump directly into Matthew Bird Creek untreated. Check out the images and video below!

February 28, 2019 - We recently completed two infrastructure project designed to reduce flooding and improve water quality. Check out a few images of the work below!

December 7, 2018 - Stormwater is in the news! The Montana Section of the American Society of Civil Engineers (ASCE) recently released their 2018 Report Card for Montana's Infrastructure. Overall, Montana received a C for its infrastructures, which include schools, bridges, energy lines, railroads, and water systems. Montana ASCE graded stormwater systems for the first time, giving the infrastructure a score of D. The low rating is because most cities across the state have failed to invest or attend to the extensive networks of stormwater pipes, inlets, and utility holes buried beneath their local streets. Fortunately, the City of Bozeman has established itself as one of the leaders in Montana over the last few years by developing a sustainable program and implementing solutions to maintain thousands of assets and improve local water quality. Please visit the following link to read the full report:

September 17, 2018 - We are pleased to announce that Altitude Training Associates, LLC plans to host a BMP 201R SWPPP Administrator/Preparer Re-certification on October 19, 2018.  Please click the following link for more information - Contractor Training Announcement.


July 16. 2018 - We are pleased to announce that Clean Water Technologies plans to host an MPDES SWPPP Administrator and SWPPP Preparer Course on September 5th and 6th.  Please click the following link to access a flyer for more information. Contractor Training Announcement


July 12, 2018 - Ever wonder what cleaning out an underground stormwater pipe looks like? The video below shows a quick view of one of many activities performed by our hard-working field crews. We are responsible for inspecting, maintaining, and repairing a network of over 65 miles of underground pipe, in addition to thousands of other infrastructure assets. The work is necessary to protect public safety, prevent flooding, and keep our waterways clean. Please help them out and install appropriate controls during construction, sweep up debris in your yard and driveway, and wash your vehicles at designated car washes. Also, please slow down the next time you see city crews, give them space to work, and pass on a wave. They are working to keep Bozeman residents safe and the environment healthy.

June 26, 2018 - In partnership with the Montana Department of Natural Resources and Conservation (DNRC), we recently installed a stream gauge on Bozeman Creek. The gauge collects real-time flow and temperature information, and uploads it to a publicly accessible website. We will use the data to monitor long-term trends, improve operations, and track the effectiveness of program investments. Further, we plan to add additional instrumentation to the gauge in the future, allowing us to monitor water quality. Please click the following link to see the data: Bozeman Creek at Bozeman, MT (ID: 41H 08990)

May 29, 2018 - The City’s Midtown Urban Renewal District and Economic Development Division recently completed the first of a multi-phase streetscape project intended to improve North 7th Avenue. The designers integrated various green infrastructure components into the project, including permeable pavers, street trees, and underground soil vaults. These components will collect and absorb stormwater runoff, resulting in fewer pollutants headed to the East Gallatin. Check out the images below, and keep an eye out for future phases!

May 15, 2018 - We recently installed three stormwater treatment units downtown.  Combined, the units will treat stormwater runoff from 180 acres and collect close to 30 tons of pollutants per year that would have otherwise dumped into Bozeman Creek.  With completion of this project, the City now has ten treatment units in the ground working to protect local waterways, and plans to install more in the coming years.  Please click HERE for more information regarding this and future stormwater projects.

January 28, 2018 - We recently updated the City's  Stormwater Management Plan, including the addition of a Sampling and Evaluation section. Members of the public can view the document and provide comments to City Staff by clicking the following links:


November 11, 2017 - We recently completed the City’s first Sediment Management Facility! Moving forward, Stormwater Operations Staff will use the Facility to dump and filter turbid water, sediment and other pollutants collected during inlet, pipe, and treatment system cleaning. The Facility will facilitate the accumulation, drying, and eventual landfill disposal of over 100 tons of debris annually, saving it from ending up in local rivers. Central Excavation, the City's contractor, prepared the video below, which gives a great overview of the project.


October 15, 2017 – In partnership with the Water Conservation Division, we recently completed a permeable paver patio area outside City Hall. Permeable pavers absorb and infiltrate rain and snowmelt rather than shedding the water and producing stormwater runoff. Permeable pavers work in patio, parking lot, and alleyway applications. We designed and constructed the project to pilot innovative techniques for stormwater control and drought tolerance and to inspire others to think outside the 'typical design toolbox' on their next project.

October 1, 2017 - We are always looking for new and innovative approaches for educating residents on important issues. We recommend you scroll through the application below to learn some interesting information regarding dog waste and its impact in Bozeman. A big thank you to the City's GIS Division for developing the viewer.
