Maintaining and expanding Mainz’s approximately 800-kilometer sewer network and ensuring the safe operation of the largest municipal wastewater treatment plant in Rhineland-Palatinate costs money—and, unfortunately, that cost is rising. The consequences of the COVID-19 pandemic, the war in Ukraine, and high inflation have thrown a wrench into long-term projections in virtually all sectors of the economy in recent years. And yet, when it comes to wastewater fees, Mainz is still in good shape even in 2025.

Starting January 1, the fee for wastewater will be €2.04 per cubic meter. The fee for stormwater will then be €0.78 per square meter. That’s 42 and 3 cents more, respectively, than before—amounting to about €1.58 per month for a single-person household in the wastewater category.

That’s not exactly a small amount, but it’s still on the lower end compared to other cities in Germany. “A small consolation, as some will understandably say. And yet the comparison shows that we’re really doing everything we can to operate as cost-effectively as possible,” explains Jeanette Wetterling, CEO of Wirtschaftsbetrieb Mainz.
