Riverside Sewage Routed Through Bozeman Plant

Wastewater infrastructure is the kind of story most people ignore until it starts failing. That is basically what happened in Riverside, a neighborhood and country club area on Bozeman’s edge that had been relying on an old lagoon system with documented problems for years. Now the fix is real — as of May 1, 2026, Riverside’s sewage is being pumped to Bozeman’s Water Reclamation Facility through a newly completed lift station. That matters because this is not just a pipe reroute. It is a public-health and water-quality upgrade tied to annexation, billing changes, and the end of a long local standoff.

Instead of wastewater flowing into Riverside’s old treatment setup, sewage now collects in an underground tank, gets pumped through the lift station, and heads to Bozeman’s main treatment plant. The city finished construction recently, and local coverage pegged May 1 as the switchover date. (kbzk.com) ### Why was Riverside’s old system a problem? Riverside had been using a lagoon-based wastewater system built in the 1970s. That kind of setup can work, but this one had been in trouble for a long time. Montana DEQ flagged deficiencies back in 2011, and city documents say the lagoons were leaking. Once that happens, the issue stops being abstract engineering and becomes a groundwater and river-protection problem. (kbzk.com) ### Why send it to Bozeman? Because Bozeman already has the higher-end plant. The city’s Water Reclamation Facility uses mechanical treatment rather than the older lagoon approach, and utilities director Shawn Kohtz described it as one of the best treatment systems in Montana. The plant is already processing roughly 7.5 million to(kbzk.com)ve a failing standalone one. (kbzk.com) ### How long has this been brewing? A long time — more than a decade, really. City records show discussions about connecting Riverside to Bozeman’s wastewater system go back at least to 2014, with a formal annexation framework adopted in 2019. Property-owner petitions were acknowledged in December 2021, and the city provisionally (kbzk.com)ing through engineering, financing, and local government steps for years.

The annexation brought Riverside properties into the city’s sewer system and turned residents into city sewer customers. That also means billing changes — first a flat sewer rate, then a metered system as individual water meters are installed over roughly a two-year rollout that started in early 2026. (bozeman.net) ### Are residents done paying for changes? Not quite. The city says homeowners are responsible for meter installation costs, and some properties may face charges tied to sump pumps discharging into the sanitary sewer until those connections are removed. Residents still get potable water service from the Riverside Water & Sewer District for now, so the(bozeman.net)osts and rules attached. (bozeman.net) ### Why does the river keep coming up? Because treated water does not disappear — it goes back into the watershed. In this case, Bozeman’s treated effluent flows to the East Gallatin River, which people use for recreation and which also matters to downstream communities. That is why city officials keep framing this as a water-quality story, not just a neighborhood utility upgrade. Better treatment upstream means less risk carried downstream. (kbzk.com) ### So what is the real takeaway? This is what boring infrastructure wins look like. Riverside’s failing lagoon system is effectively being retired, Bozeman’s plant takes over the treatment job, and a years-long annexation fight finally turns into something physical and operational. The catch is that the cleanup comes with new cit(kbzk.com)system now goes through a much stronger one. (kbzk.com)
