Czech municipal wastewater upgrades

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.
