KAMNIŠKA RIVER BASIN
• 9 municipalities, 298 settlements,
77.668 inhabitants• industry: chemical, metal, food
production, textile, leather

WATER QUALITY ASSESMENT
• surface water quality: class 1 for the spring and class 3-4 at the outflow to the Sava River
• no data on impact of two major cities on water quality
• ground water quality monitored on 7 observation stations

WATER QUALITY MONITORING
• ground water quality monitored on 7 observation stations
• ground water level monitored at 5 stations, onls to at the same point
• drinking water quality monitored regullary (not best quality)
![Page 12: Ministry of Environment and Spatial Planning, Slovenia KAMNIKA BISTRICA river basin management plan Lille, March 2002](https://reader035.vdocument.in/reader035/viewer/2022062909/5a4d1bb27f8b9ab0599cd012/html5/thumbnails/12.jpg)
WATER SUPPLY
• 9 sources of water from groundwater, no treatment of drinking water
• 2 water supply systems (operated by 2 public service companies); 17.000 connections
• length of public networks: 420 km• 98 % inhabitants served with drinking water• no data on water use by agriculture
![Page 13: Ministry of Environment and Spatial Planning, Slovenia KAMNIKA BISTRICA river basin management plan Lille, March 2002](https://reader035.vdocument.in/reader035/viewer/2022062909/5a4d1bb27f8b9ab0599cd012/html5/thumbnails/13.jpg)
SEWAGE NETWORK
• length of sewage systems: 220 km• in 4 municipalities 85% population
connected, in others very poor infrastructure,
• obsolete network
![Page 14: Ministry of Environment and Spatial Planning, Slovenia KAMNIKA BISTRICA river basin management plan Lille, March 2002](https://reader035.vdocument.in/reader035/viewer/2022062909/5a4d1bb27f8b9ab0599cd012/html5/thumbnails/14.jpg)
WATER TREATMENT
• in 4 municipalities 85% wastewater treated (highest rate in Slovenia)
• in others no treatment• dispersed pollution very high; pig farm
discarges directly to the river
![Page 15: Ministry of Environment and Spatial Planning, Slovenia KAMNIKA BISTRICA river basin management plan Lille, March 2002](https://reader035.vdocument.in/reader035/viewer/2022062909/5a4d1bb27f8b9ab0599cd012/html5/thumbnails/15.jpg)
WATER USE
• not all uses of water identified; only households and industry
• households use 40% of water amounts, industry 60 %
• industry use in decline, threat of illegal abstraction directly from ground water
• agriculture use substantial (irrigation, 12 fish farms, 10 fish ponds), no payment for water use
![Page 16: Ministry of Environment and Spatial Planning, Slovenia KAMNIKA BISTRICA river basin management plan Lille, March 2002](https://reader035.vdocument.in/reader035/viewer/2022062909/5a4d1bb27f8b9ab0599cd012/html5/thumbnails/16.jpg)
FLOODS
• frequent flood accurance = high costs of damages
• due to unproper spatial planning (responsibility of municipalities)
• policy to involve assurance companies in damage covering not developed yet
![Page 17: Ministry of Environment and Spatial Planning, Slovenia KAMNIKA BISTRICA river basin management plan Lille, March 2002](https://reader035.vdocument.in/reader035/viewer/2022062909/5a4d1bb27f8b9ab0599cd012/html5/thumbnails/17.jpg)
LESSONS LEARNED
• poor and obsolite infrastructure network, high investmet needs
• assets depreciated; no room for capital costs incl. in price
• high requirements following the implementation of EU legislation - to cover the gap in a limited time frame
![Page 18: Ministry of Environment and Spatial Planning, Slovenia KAMNIKA BISTRICA river basin management plan Lille, March 2002](https://reader035.vdocument.in/reader035/viewer/2022062909/5a4d1bb27f8b9ab0599cd012/html5/thumbnails/18.jpg)
LESSONS LEARNED
• not all water uses identified• no tradition in proper pricing (only
operating costs of water services included)
• due to social reasons prices for water services were kept low for too long
• absence of common appoach in solving problems related to river basin, municipality by municipality approach
