2. 04/12/04 Environmental Protection Agency/Lithuania TABLE 4: National population connected to waste water treatment plants

3. 04/12/04 Environmental Protection Agency/Lithuania Table 4: data supplied before project National resident population1000’sYES % of national resident population connected to: Urban waste water treatment (44), of which (a): % of pop. NO - Primary treatment (47) % of pop. NO - Secondary treatment (48) % of pop. NO - Tertiary treatment (49) % of pop. NO Other waste water treatment (b) (45) % of pop. NO Urban waste water collecting system with treatment (c) % of pop. NO Urban waste water collecting system without treatment % of pop. NO Total urban waste water collecting system (41) % of pop. NO Independent waste water collecting system % of pop. NO of which with independent treatment (46), total % of pop. NO of which at least secondary treatment % of pop. NO

4. 04/12/04 Environmental Protection Agency/Lithuania Data sources Data used from: The Total Population Census, 2001 (SD) Waste water database (EPA) Data wasn’t included from: Regional Environmental Protection Departments Municipalities

5. 04/12/04 Environmental Protection Agency/Lithuania The Total Population Census’2001 Total population of Lithuania in 2001 – 3 487 000 In 2003 total population decreased by ~ 41 000, i.e. less than 1% Statistics includes data about ~1500 cities and settlements with population of > 200, this is ~ 85% of tot. pop. TPC’2001 Questionnaire includes question “Are you connected to a sewer?” Storage tanks are included in WWCS

6. 04/12/04 Environmental Protection Agency/Lithuania Population density in Lithuania

7. 04/12/04 Environmental Protection Agency/Lithuania Waste water database Database includes data on about 1069 WWTPs From DB 327 WWTPs were selected which: a. corresponds to JQ UWWTP and other WWTP, i.e. IWWTP definitions and b. have data on influent and effluent about: TSS, BOD (at least) + COD, N, P. No data about independent WWTP is supplied to DB.

8. 04/12/04 Environmental Protection Agency/Lithuania Settlements connected to WWCS

9. 04/12/04 Environmental Protection Agency/Lithuania Population excluded from WWT analysis  Rule: if settlement’s treatment plant could not be identified then this settlement is excluded, i.e. defined as not treated Data about population is excluded: in settlements < 200 pop. of all pop. – 516 465 (14.8% ) in settlements and towns which are connected to WWCS:  with < 1 000 pop. – 288 291 (8.3% of total pop.)  with 1 000 - 2 000 pop. – 36 352 (1.0% of total pop.)  with 2 000 - 10 000 pop. – 47 186 (1.4% of total pop.)

10. 04/12/04 Environmental Protection Agency/Lithuania Identification of WWT category For identification of a WWT category JQ treatment plants classification was used WWT category of a particular WWTP was identified according to requirements of UWWT Directive: i. was applied principle “and” for treatment efficiency for all indicated parameters ii. treatment efficiency of Coliforms has not been taken into account

11. 04/12/04 Environmental Protection Agency/Lithuania Table 4 (interim results for 2003): National resident population1000’s3445.7 % of national resident population connected to: Urban waste water treatment (44), of which (a): 1 % of pop. 59.0 - Primary treatment (47) % of pop. 31.5 - Secondary treatment (48) % of pop. 7.5 - Tertiary treatment (49) % of pop. 20.0 Other waste water treatment (b) (45)2 % of pop. 2.7 Urban waste water collecting system with treatment (c)1+2 % of pop. 61.7 Urban waste water collecting system without treatment3 % of pop. 10.7 Total urban waste water collecting system (41)1+2+3 % of pop. 72.4 Independent waste water collecting system: % of pop.

12. 04/12/04 Environmental Protection Agency/Lithuania Waste water treatment in Lithuania

13. 04/12/04 Environmental Protection Agency/Lithuania Problems (1) TPC’2001 data does not indicate WWCS type, i.e. system of conduits, storage tanks or combined system. There is no data about treatment on part of settlements which are connected to sewer. In case there is no data about WWTP in a settlement it’s impossible to indicate treatment category. Should this part of population be excluded from WWT, although they maybe are treated? Proposals (draft) of the Commission: Storage tanks are no collecting systems in the terminology of the UWWT Directive.

14. 04/12/04 Environmental Protection Agency/Lithuania Problems (2) There is no definition of individual treatment plant in Lithuania, so no data about independent treatment is available in Lithuania. Incomplete data on influents. WWTPs usually supply all required data on effluents, but not so eagerly on influents.

15. 04/12/04 Environmental Protection Agency/Lithuania Conclusions TPC’2001 data on population could not be used forever. So, more sophisticated methodology for assessment of population connected to WWT should be developed. Data collecting system in waste water field should be changed to fill gaps of JQ and to fulfill reporting obligations to the Commission.

16. 04/12/04 Environmental Protection Agency/Lithuania TABLE 6: Sewage sludge production and disposal

17. 04/12/04 Environmental Protection Agency/Lithuania Task: Collection of information on sewage sludge production and disposal Activities: Correction of existing order for collection of primary data. Done Analysis of collected primary data. Done Preparation of order for national statistical data collection. On the preparation

18. 04/12/04 Environmental Protection Agency/Lithuania Problems Collected primary data analysis has showed that: Significant amount of WWTPs has not supplied data Data supplied is not comprehensive Majority of WWTPs has not provided data about sewage sludge amount in dry solids and m 3 Outcome - there is no possibilities to fill Table 6 of JQ for 2003 Outcome - there is no possibilities to fill Table 6 of JQ for 2003

19. 04/12/04 Environmental Protection Agency/Lithuania Solutions Data collecting problems on sewage sludge in Lithuania could be and will be solved by legal means only. On July, 2004 will come into force package of new legal acts on statistical accounting of waste (in Lithuania sewage sludge is attributed to solid waste field): The Permits for Activity The Waste Treatment Rules The Rules on Sewage Sludge Use

20. 04/12/04 Environmental Protection Agency/Lithuania The Waste Treatment Rules EWC-Stat included Waste recovery [R] and disposal [D] definitions corresponds to EU legislation and JQ Mandatory primary data reporting for waste producers and treaters  We shall include sewer sludge reporting in dry solids and cubic meters

21. 04/12/04 Environmental Protection Agency/Lithuania The Rules on Sewage Sludge Use Reporting forms on sewage sludge use will be improved to fulfil reporting obligations (93/481/EC and 94/741/EC) to the Commission
