Dubrovnik 2009. Conference Island of MLJET NEEDS & OPPORTUNITIES IN INFRASTRUCTURE KOMUNALNO MLJET D.O.O. FRANO HAZDOVAC, DIRECTOR
General information • Mljet is situated in the South Dalmatian Archipelago. The southernmost and easternmost of all our major islands • Area 100.4 km 2 with an average width of 3 km and length of 37 km (8.-largest island in Croatia). • Population: 1111 (according to the 2001 census.) • 21 villages, 13 coastal villages and 8 in the interior of the island
Observation Framework • Distance from the mainland (5 NM) and county center Dubrovnik (24 NM) • Dispersal and settlement total poor population (average: 11 inhabitants / m2 and 53 inhabitants / village) • Extremely long island (37 km air distance) • Outdated and inadequate municipal infrastructure • Variations in the number of users of public services and utilities (winter and summer conditions) • Low usage renewable energy sources
Local water supply system flow: 12 l/sec • Water supply is provided by brackish water desalination - reverse osmosis • Installed 3 independent RO Systems • RO Sobra capacity 800 m3/day • RO Blato capacity 250 m3/day • RO Kozarica capacity 50 m3/day • Water storage capacity of 1300 m3
Distribution of potable water is organizedwith tank cars Water supply system exists only in 3 villages Needs for drinking water are major features of the production and supply Costs Water transportation Electricity Maintenance, spare parts and raw materials Labor Force Inadequate position of the production units Water supply on island
Additional water flow of 10 l / sec (NPKLM / RO) Water network in the length of 50 km Water tanks with total capacity of 15000 m3 Additional sources of power for pumping water and producing Additional sources of power for lifting water level Needs in water supply
Opportunities in water supply • Installing PV panels on all water facilities approx: 5000 m2 • Use of PV panels on the surface of 5000 m2 gives a 1 MW installed capacity what is more than enough for the whole island needs • Use the resulting energy in places without the possibility of accession to the electrical grid • Potential water use in the raised geographic points (gravitational potential)
Drainage and sewage • In the phase of major projects and obtaining permits for building 8 drainage systems on the island
Drainage and sewage Energy needs • For 7 drainage systems in areas outside the National Park Mljet installed power will be 9.43 kW / system = 66.0 kW total • For the drainage system in the National Park Mljet installed power will be 161.83 kW • In the case of the power failure additional sources of electricity supply should be provided with diesel engines
Independent Municipal Power System – IMPS for Sutmiholjska bayexample
General information for Sutmiholjska bay • This is part of the village of Babino Polje, former fishing village but now formed as a new potentially interesting tourist destination. • Located on the south side of the island suitable for the use of renewable energy • The lack of communal infrastructure needs investments in the construction of water supply, sewerage, public lighting, etc., presents a challenge to think about forming an Independent Municipal PowerSystem (IMPS)
