Kurzbeschreibung
(Englisch)
In Switzerland, only about 2.7% of the population are currently not connected to public sewer networks. The 2.7 % can be further classified as i) farms which collect their sewage together with animal manure and ii) residential buildings with on-site and decentralised sanitation solutions such as small-scale wastewater treatment plants (SSWWTPs) or septic tanks. To date, the inventories of greenhouse gas (GHG) emissions from wastewater management in Switzerland have taken into account the public systems only, i.e., the municipal and industrial sewerage, wastewater treatment and sludge management systems. So far, on-site and decentralised wastewater management systems have not been considered. This is based on the assumption that the 2.7% of wastewater managed on-site does not contribute significantly to the GHG emissions due to low water temperatures which prevent the generation of methane (CH4). This assumption is, however, questionable, as temperatures are not constantly low, especially during summer months and in lower-lying areas.
