Implementation of the Water Framework Directive and other ...

Wastewater treatment and WFD 1 st December 2005
implementation in CEE Danube countries Bratislava, Slovakia
The concerned region comprises the river basin of the Isar upstream of Munich. 9 treatment
plants with together about 300 000 p. e. are now equipped with UV-radiation installations
operating since 2003 during the summer period (15 th April to 30 th September). The
municipalities participate voluntarily. State subventions were given.
The waste water treatment plant of Bad Tölz (82 000 p. e.) in the Alpine region was the first
plant with the disinfection of the waste water. The costs for the disinfection installation were
654 000 €, the yearly operation costs are about 20 000 € (1,2 cent/m 3 ).
The success of the “Upper Isar” programme stimulated the city of Munich and 5 towns in the
North of Munich to equip their treatment plants also with UV-radiation installations. Thus in
total 16 treatment plants including Munich II with about 1 730 000 p. e. dispose now of UVradiation
installations. The river quality control showed that in summer time the limit values
of the bathing water directive are nearly always complied with. Only during or shortly after
heavy rainfalls the river quality deteriorates.
Today other regions in Bavaria consider the possibility to disinfect their waste waters, too.
7 SENSITIVE AREAS DEFINED IN THE NATIONAL LEGISLATION AND
MEASURES APPLIED
In Germany all areas draining into the North Sea and the Baltic Sea are sensitive areas. The
German Danube river basin is not a sensitive area with the exception that the following parts
of the German Danube river basin are designated as sensitive areas:
- Catchment basins of the larger South Bavarian lakes.
- Catchment basin upstream of the Danube infiltration
In these areas, organic and nutrient pollution are eliminated following at least the
requirements of the UWWD.
In Germany no area has been designated as less sensitive area.
8 WATER PRICING AND ECONOMIC REGULATIONS
Article 9 WFD requests the recovery of the costs of water services (i. e. waste water disposal
and treatment services). Article 9 also requests that environmental and resource costs are
taken into account. This is partly done by imposing conditions on the discharge of treated
waste water and compensation measures. Member States are also asked to ensure by 2010 that
water pricing policies provide adequate incentives for users to use water resources efficiently.
8.1 Waste water disposal costs
Costs for wastewater disposal are made up as follows:
- Investment costs
- Operating costs (staff, plant equipment, maintenance)
- Reserves for replacements – amortisation
- Taxes and charges
The following average values can be given for Bavaria
Investment costs
Collecting system
Urban areas 1500-2500 EUR/inhabitant
Rural areas 2000-5000 EUR/ inhabitant
Sewage purification
Large plants (> 100 000) approx. 400 EUR/ inhabitant
Smaller plants (< 5000) approx. 800 EUR/ inhabitant
