In July 2026, Polish municipalities began large-scale upgrades to water supply and storm-water networks, including new intakes, storage tanks, expanded mains, and a modernized sewage-treatment plant in Brzezinach. The national “Mikroretencja” scheme continued to support households without public sewers, covering up to 70% of costs (capped at 11,000 zł). On 26 July 2026, the government detailed typical investment costs—15-25k zł for a treatment plant and 6-12k zł for a septic tank—noting that many gminas publish local grant calls. The nationwide rain-water-collection subsidy launched on 22 June 2026 with a 173 million zł budget saw strong uptake: by the end of July 2026, 5,379 applications requested 36.7 million zł, prompting the National Fund for Environmental Protection and Water Management to warn the programme could close in Q4 2026. A parallel local initiative, AQUAgustów in Augustów, runs until 10 November 2026, offering up to 60% reimbursement (max 2,000 zł). In the Silesian Voivodeship, the regional micro-retention programme received 1,000 applications between 22 June and 27 July, requesting approximately 6.93 million zł of the 20.6 million zł allocated. The city of Siemianowice Śląskie launched the “Siemianowicka Kropelka” scheme on 10 July, granting up to 10,000 zł (covering 50% of costs) for rain gardens and underground tanks. Regional efforts for sewage infrastructure expanded in the Łódź Voivodeship, where the Provincial Fund for Environmental Protection and Water Management (WFOŚiGW) launched a program to support up to 2,316 installations across 50 municipalities. This initiative provides up to 8,000 zł per household for private sewage treatment plants, with a total budget of 61.8 million zł. In August 2026, the WFOŚiGW prepared a specific program for the installation of 625 new biological sewage treatment plants. Concurrently, municipalities have launched nationwide inspections to ensure compliance with wastewater management laws. ## Timeline ### 2026-08-20: Wody Polskie increases inspections of groundwater wells Wody Polskie is increasing inspections of groundwater wells due to rising illegal extraction.
