When analysing new types of sewage systems, knowledge is needed on
the composition of the different wastewater fractions. The computer model
URWARE, developed from the model ORWARE, is intended to analyse and
compare different wastewater system structures, e.g. to compare wastewater
systems where urine and/or faeces are source separated with conventional
wastewater systems, where the different wastewater fractions are mixed
with each other. To use URWARE for this purpose, knowledge was needed
on the composition of the wastewater fractions urine, faeces and household
greywater. Sometimes the compostable household waste is mixed into the
wastewater by use of a food waste disposer and thus also the composition
of the solid compostable household waste is needed. Thus, the objective of
the present report was to collect the knowledge on the mass and composition
of urine, faeces, greywater and compostable household waste in Sweden.
