Lead Prohibition in Drinking Water Installations Effective January 12, 2026
Starting January 12, 2026, it is no longer permissible in Germany to have drinking water pipes, fittings, or installations containing lead. This regulatory change comes through an amendment to the German Drinking Water Ordinance (Trinkwasserverordnung), which aims to eliminate the toxic heavy metal from contact with drinking water due to its harmful health effects. Property owners must replace or deactivate any lead-containing water installations and notify the responsible district authority upon completion of these measures. This ban applies irrespective of current lead concentration in the drinking water; even pipes coated internally with epoxy resins must be replaced or taken out of service by this date. Installers discovering lead materials during their work are required to report this to local health authorities without delay unless already commissioned to undertake renovation work [Source 1][Source 3][Source 7][Seed Article].
Implications for Expats, Tenants, and Property Owners in Germany
The lead ban carries significant practical relevance for expats, international students, and foreign workers residing in Germany, especially those living in older buildings. Many properties, particularly in northern and eastern regions, still have original water supply lines made of lead, often dating back to the early 1970s or earlier. According to the Environment Agency and reports from water utilities, around 15,000 lead water mains were still reported as recently as 2021, and some public facilities including schools and kindergartens have tested above legal lead limits in water samples. Residents are advised not to drink or cook with water that has stagnated longer than usual in such pipes and to seek advice from health authorities or qualified sanitation professionals when lead contamination is suspected. Tenants whose water supply exceeds lead limits have the right to involve local health offices and can hold landlords accountable for compliance. Landlords who fail to remove lead pipes risk legal consequences because providing safe drinking water is a legal obligation [Source 2][Source 5][Source 6][Source 8][Seed Article].
The regulation also anticipates stricter limits from 2028, lowering the permissible lead concentration in drinking water from 10 micrograms per liter to 5 micrograms per liter, thereby reinforcing the gradual phase-out and continued vigilance against lead exposure [Source 5][Source 7].
Reporting and Compliance Obligations for Installers and Water Suppliers
Under the revised Drinking Water Ordinance, both water suppliers and installation companies must inform health authorities immediately if they detect lead-containing pipes or fittings during their operations. This transparency facilitates timely intervention and protects public health. Additionally, water providers are mandated to notify consumers promptly if lead components are found in supply systems managed by them. From January 12, 2026, repairs involving lead pipes are not permitted even as temporary fixes, emphasizing the finality of the ban. These regulatory changes place a clear responsibility on building owners and service providers to ensure drinking water safety and legal compliance [Source 1][Source 3][Source 7][Seed Article].
For expats and other residents, knowing these obligations is crucial for proactive health protection and legal compliance. If lead pipes are identified, arrangements for replacement should begin as soon as possible to meet the 2026 deadline and avoid any disruptions or legal issues [Source 3][Source 8].
