1. Presentation of the Hungarian Grant Project
Improvement of the statistics on industrial water use
and wastewater discharges
Hungarian Central Statistical Office
Environment Statistics Section
by Pál AUJESZKY
Meeting of the Working Group Statistics of the Environment Sub-Group “Water”
(Luxembourg September 2006)

2. Hydrological Background
Hungary is situated in the Charpatian basin, and the 96% of our surface water comes from the upstream countries,
In Hungary the role of ground waters is very important, because,
66% of the groundwater is vulnerable against the pollution from the surface.

3. The industrial water use and waste water treatment in Hungary ---- The Hungarian data in the OECD/Eurostat Joint Questionnaire:

4. The water statistics is divided between HCSO and the Ministry of Environment and Water and their regional offices and authorities.
The yearly report of the Hungarian Central Statistical Office on the water supply, waste water collection and waste water treatment of settlements, which was revised in 2002 and 2003 to fulfil the EU/OECD requirements.
Full scope questionnaire!

5. The HCSO data collection:
This data collection covers the public water supply and waste water collecting branches of the waste water treatment Loading scheme according to the JQ. See on the next slide, red arrows.
quantitative and qualitative data on discharged waste water are collected
completed with a meta database
available on the web side (
WWT Investment data are collected by agglomerations

7. Statistical questionnaires of Ministry of Environment and Water :
1364 Report on pollution of surface water
1365 Report on pollution of public sewerage
1376 Report on the technical data of the public water works and waste water plants
1378 Report on the water use of industries (but there is a threshold: water use is more than 5m3/h and 80m3/day

8. Administrative data sources of Ministry of Environment and Water 1. :
Water resources fee statistics for water user with a water use licence, yearly updated
Legal base: Act on water management
contains the all water abstractions according to
NACE categories, geographical locations,
the type and quality of abstracted water
the aim of water uses

9. Administrative data sources of Ministry of Environment and Water 2.:
27/2005.(XII.6.)KvVM ministerial regulation on surface water quality (reference year 2004)
From this administrative data collection, could be determined
the quantity and quality of discharged waste water and sludge
the technology of waste water treatment
the quality of pollutants
according to NACE categories, and geographical locations.

10. – Remarks to the reports of MoEW
these questionnaires are not a full-scope questionnaires
main purpose is not to fulfil the statistical aims and requirements
OECD and Eurostat Joint Questionnaires are not based on EU Regulations directly
there is not a standard grossing-up methods to calculate a real national data
the non-response problem is also untreated
data suppliers are where and when the environmental inspectorates take a measure,
there is no standard process to calculation of the substance flows from measured data
self-control by accredited laboratories

11. – Remarks to the 1378 report of MoEW
The report on industrial water use contains and works up data of water abstraction and water treatment of industrial water users, which have a water use over 5 m3/h, respectively 80 m3/day.
Not full scope
non responses are not treated
there are not estimations methods
etc.

12. The existing report on industrial water use
The data sheets contain:
main data of data supplier (plant, work);
sources of water acquisition;
flow across and returned water uses;
quality and deposit method of plant leaving used and waste water;
capacity of used and waste water treatment plants and storage units;
data of peak period ;
general data.
Advantage of the informational system would be the data collection and registering by plants.

13. To fulfil EU requirements, we tried to solve the problems by using Eurostat Grant-project
Grant 2005: Industrial water use and waste water discharges (to improve also the water balance) in
We developed a new Questionnaire
introduced the technical elements of the statistical data collection system
this questionnaire will be a mandatory questionnaire
new method to determine the data suppliers
no thresholds for water use!
NAMEA- Water will be possible

14. The content of the new questionnaire
Water use plants of data supplier with NACE codes and geo-codes
Water use by sources, by quality in 1000m3/year
Returned water uses
Water losses
Discharged water, and treatment
Identification of water bodies
Water prises etc.

15. The guidelines, data flow, databases for the new questionnaire
There is also a guideline for this new questionnaire on industrial water use and waste water discharges
The questionnaires will be sent to the regional water authorities
Data entry,
non response, estimation etc.
The controlled data will be stored in a database in the Ministry of Env. and Water

16. Main results and conclusions of the Grant 2005
Goal: Improve the industrial water balance:
Partners: MoEW and its consultant – good co-operation
We elaborated a NEW questionnaire on Hungarian Industrial water use and waste water discharges
Data from this new questionnaire will be available from the reference year 2008 according to the National Statistical Programme
Full scope (100%) questionnaire

17. Further improvements on water statistics connected to grant project TF 2004 and Grant 2006? (QR on water stat.)
TF 2004 / Water:
We will elaborate an emissions register (more than EPER)
and an inventory for waste water treatment plants
We will also elaborate:
estimation methods for non-measures values by emission factors,
concrete statistical sampling methods for waste water discharges for non-response.

18. TF2004 project: we established a Working group from experts
Our partner were originally the MoEW, and the National Directorate of Environment, Nature and Water (NDENW)
The National Directorate of Environment, Nature and Water was ceased by the Gov. in 2006.
The legal successor is the VITUKI Pbc.
The change of the partner causes some delay and changes in the original time schedule.
So we started the work with the WWTP inventory from HCSO data.
The inventory will be made by MS-Access, to avoid the mystery of IT and the mystery of huge non transparent systems (e.g. Oracle)

19. Suggested Further Helps from Eurostat
Final Version of Water Statistics Manual 2.0
Water statistics regulation is very important like in the Waste statistics
More GRANTS!!!!!
Eurostat requirement to support the project team directly at least 30% of total costs (like in subcontracting 20%), to make interested the experts involved in the project
Workshops yearly, to keep the leading role of Eurostat on water statistics also, according to the old statistics (agriculture, waste etc.)
Study Visits
And after these steps the Water STATISTCAL regulation!!!

20. Thank you for your Attention!
