How are diffuse loads
derived? Emission

information missing
None. Loads are used
directly based on the
data
Applied
workaround
Domestic loads
No measured loads
available  Emission
factors used
Values for TN, TP,
SS, BOD. Other
Priority (hazardous)
substance are missing
Geo reference

No issues
Industrial loads
No measured loads

Most needed:
•
Industrial loads

RBE and measures

Measures
•
•
•
Measures have to be defined in relation to
ecological key factors
Three types of measures:
• point sources
• diffuse sources
• ecological measures

Definition of measures in RBE
Top left: general characteristics:
•
ID (user defined)
•
Name (user defined)
•
Type (point source, diffuse
source, ecological measure)
•
Objects (automatically)
•
Variables (automatically)
Top right: detailed information:
•
Type of emission source
(agriculture/WWTP/...)
•
Substance affected by
measure
Lower half: measures are
assigned to nodes by table
or map

Cost module in RBE
In the cost module the following data can be specified:
•
Investment: costs for financing the measure or measure
collection
•
Depreciation period: this is the life span over which the
value of the measure or measure collection is reduced to 0
and should be equal to the time period needed to pay back
the investment.
•
Maintenance: costs to maintain the measure or measure
collection. The assumption is made that maintenance is
perpetual.
•
Land costs: for some measures or measure collections
acquisition of land is necessary.
•
Depreciation period of land: normally these costs are very
low, but it is included for the sake of transparency
•
Data about costs must still be gathered. Homework!

Starting point: long list of measures in Draft
Büyük Menderes RBMP
Check on completeness of existing long list
In two groups we’ll make a matrix with the
measures and additional information about the
measures
Plenary presentation of the results

Matrix with measures
settlements without WWTP
COD, N, P,
Priority substances
constuction of WWTP for
settlements above 2000 inhabitants
appropriate treatment for settlements
smaller then 2000 inhabitants
reuse of treated waste water in
agriculture
training of local staff of WWTP
