Hrvatske vode

UWWT directive in Croatia implementation and data availabilityWest Balkan Regional Workshop on UWWTD and SoE Emissions to Water

Skopje, 18 19 June 20131Water sector responsibilities are shared among:Croatian Parliament with the National Water CouncilGovernment of Croatia - Ministry of Agriculture andHrvatske vode as the national agency for water management

ADMINISTRATIVE STATE ORGANIZATIONSCROATIAN PARLIAMENTGOVERNMENTHRVATSKE VODENATIONAL WATER COUNCILMINISTRY OF AGRICULTURESTANDING COMMITTEE FOR ECONOMYNATIONAL AGENCIES(owned by the Government, public services)MINISTRIESInstitutional framework for UWWTD: Ministry of Agriculture, Water Management Directorate - competent authority for managing water management system responsible for the administrative supervision over the implementation of the Water Act as well as implementation of water utility directives

Hrvatske vode (HV) - legal entity for water management, established under the Water act (its founding act) Public water utility companies - established by the units of local and regional self-government - responsible for water supply and collecting and treating of the waste waters

Other institutions involved:

Croatian Environmental Agency (CEA) - responsible for reporting to EU and other institutions

Central Buerau of Statistics (CBS) - national institution responsible for statistical reports, including reporting to Eurostat in cooperation with CEA

3Data required by UWWTD: source of data I: water utility companies (quantities, effluent quality, discharge points etc.) source of data II: Hrvatske vode (sensitivity of receiving areas, GIS spatial data) source of data III: Central Buerau of Statistics (general population data, tourism etc.)

all data will be collected and processed by Hrvatske vode on a national scale data base for collecting data directly from the source and preparing them for reporting does not exist in entirely appropriate form; it is planned to be adapted according to the information necessary for the water management as well as EU reporting as a new EU member upon receiving Q2013 on UWWTD it will be filled by Hrvatske vode and upload to CDR will be done by the Croatian Environmental Agency

Experience in UWWTD reporting:

Croatia was not obliged to report any data concerning UWWTD (exception statistical data reported by CBS, and some data delivered to ICPDR PM Group) Hrvatske vode has never participated in any EU reporting exercise on this issue- Web Dem Tool was not used so far, but HV and CEA have received passwords for the use of Tool for possible filling of Q20134Urban waste water - Data collection Ordinance on waste water emission limit values (OG 87/10) puts an obligationto water utility companies to send to Hrvatske vode on a regular basis:Data on the amount of discharged waste waterData on completed testing of quality of wastewater on discharge points

Hrvatske vode are required to verify the submitted data and process the data in the mannerrequired to report on the discharge of wastewater. - data base containing submitted data is filled internally - data flow is not yet automated through the Water information system (data are submitted to HV mostly as paper reports) plan is to develop web application with standardised entry forms to be filled directly by the data source

Data exchange:

- HV has a central data base but without possibility for data exchange with other institutions 5Urban waste water - Data collection Availability of data for this workshop according to questionairre sent by ETC:

Data block 1: Country information- available: number of inhabitants, municipalities, inhabitants connected to collecting system- not available: number of inhabitants connected to IASData block 2: Municipalities- Croatia have designated agglomerations, but data on municipalities could be available as well if neededData block 3: Agglomerations- available: spatial data, data on generated load, and % of connected population- not available: rate of generated load addressed through IAS, number of inhabitants without treatmentData block 4: Industrial facilities- E-PRTR is under the responsibility of Croatian Environmental Agency

6Urban waste water - Data collection Availability of data for this workshop according to questionairre sent by ETC:

Data block 5: Waste water treatment plants / collecting systems- available: spatial data; type of WWTP and organic design capacity; type of treatment- not available: incoming load data (Croatia is not obliged to report on performance of WWTPs because of the transitional periods for implementation aggreed with EU)Data block 6: Discharge points- available: spatial data; sensitivity and type of recipient; - not available: effluent load data (not reporting yet - transitional period for implementation)Data block 7: Receiving areas- available: spatial data; list of receiving areasGeneral note: - data which are not available at this moment can be divided to two groups: 1. not recognized and not collected (eg. IAS related data), and 2. data which are not systematically collected and interpreted in central data base of HV and can not be filled to this questionerrie for now7Urban waste water - Data collection

Within the existing internal application of HV following data are collected:Basic data about the collecting system (location, recipient of effluent, population, system manager),

Data about the settlements included in the collecting system (sewerage type, connected population),

Data about the existing and planned wastewater treatment plants and discharges,Further development and improvement include GIS models of spatial information.8Spatial distribution of population and agglomerations in Croatia

4.285 million total population (2011)56.594 km2 mainland surface75.7 inh/km2 average population density6.756 settlements634 inhabitants average settlement size

SETTLEMENTS WITH LESS THAN 500INHABITANTS82% of total number - 5.568 settlements 18% of total population

FOUR MAIN REGIONAL CENTRES:

Zagreb 688.163 inhabitantsSplit 167.121 inhabitantsRijeka 128.384 inhabitantsOsijek 84.104 inhabitants- representing ~30% of total population (together with near-by smaller settlements)

Agglomerations concept:one agglomeration is served by one collecting system, and by one WWTP;total number - 763 agglomerations of which 294 are > 2.000 PE

Agglomerations > 2.000 PE around 93% of the estimated maximum load representing 80% of population which should be connected to the sewarage system

Cost for the implementation in all 294 agglomerations is estimated aroundEUR 3.2 bil.12
