Developments: 2. In late July 2026 Czech municipalities began a series of upgrades to improve wastewater treatment and reduce environmental impacts. Sedlec started a 350,800‑CZK refurbishment of its plant’s aeration system, replacing all 32 aeration elements installed in 2004. Nearby Litovel launched a month‑long pilot of a dry‑steam odor‑reduction device at its solar sludge dryer, aiming to curb resident complaints and increase the use of dried sludge as fuel for a local cement plant. A week later, Jihlava approved a 26 million‑CZK investment to replace its mechanical aeration system with bubble‑injection technology, projected to cut energy consumption by about 60 %. An additional 11 million CZK will fund a study on boosting biogas production from sludge and exploring food‑waste feedstock. In České Budějovice, authorities allocated 98 million CZK for extensive renovations of several kindergartens, including insulation, new photovoltaic panels, and upgraded utilities, to lower energy use and operating costs. Together, these actions illustrate a coordinated push by Czech towns to modernize wastewater infrastructure, adopt energy‑saving technologies, and explore renewable energy opportunities. ## Timeline ### 2026-08-04: Jihlava and Budějovice start major energy‑saving infrastructure upgrades Jihlava invests CZK 26 M in a new bubble‑aeration system and biogas study for its wastewater plant, while České Budějovice spends CZK 98 M on energy‑saving renovations of local schools. 2 sources. https://clstr.news/cluster/jihlava-and-budjovice-start-major-energysaving-infrastructure-upgrades ### 2026-07-25: Czech towns modernize wastewater treatment facilities Sedlec refurbishes its wastewater plant’s aeration system and Litovel tests a new dry‑steam odor‑control device at its solar sludge dryer, both aiming to improve treatment efficiency and reduce nuisances. 2 sources. https://clstr.news/cluster/czech-towns-modernize-wastewater-treatment-facilities --- Cite as: Czech municipal wastewater upgrades.
