Mayor's Canal

from Wikipedia, the free encyclopedia

A mayor's canal is colloquially a public sewage system of older, informal origin for rainwater or treated sewage. In wastewater tax law called such investments part local sewer .

The term is used colloquially for canals that were generally used for drainage in rural areas and some of them are still used today (especially rural areas in Central Germany). It is mostly about sewage systems that z. B. manufactured as piping in sections and only later put together as a collection system. The canals then flowed into the next receiving water .

Transitionally, pre-treated wastewater from septic tanks was and is being introduced into the mayor's sewers . Today the term sub-urban sewerage is often used in this context. While these systems used to be seen as a temporary solution until they were connected to a central sewage treatment plant, they have established themselves as permanent solutions in some places since the 1990s. However, the aim is to replace the old septic tanks with modern, fully biological small sewage treatment plants.
