PROJECT PORTFOLIO

under the Sector for Investment and Development, ViK prepares and implements many projects.

There are 3 main groups of them:

1. ViK’s investments (financed mostly from develoment fee)2. EU-financed smaller projects; financed out of: INTERREG (4 research projects); RURAL DEVELOMENT (2 smaller infrastructure

projects) and CEF (financed out of INEA)3. Projects of agglomerations KAŠTELA-TROGIR and SPLIT-SOLIN

(EC-Cohesion fund)4. Drinking water conditioning plant (in preparation).

VODOVOD I KANALIZACIJA d.o.o. SPLITCHALLENGES - WATER SUPPLY

DRINKING WATER SOURCES TRANSMISSION EXISTING WASTER SUPPLY NETWORK

STATUS: Sensibility of Jadro and Žrnovnica; over-exploitation of water

source Jadro

STATUS: Losses in water delivery at Jadro, pollution risk, overflow at PS

Ravne Njive

STATUS: High apparent losses in distrubution system, high real losses

in system, low system autonomy

TARGET: Subterranean water protection, rationalisation of water

catchment at Jadro source.

TARGET: To improve water-body of Jadro, to minimize potential risk

pollution, to minimize the overflow losses.

TARGET: Reduction of apparent losses due to unappropriate

watermeters and unauthorised water consumption, progressive reduction

of real losses (short-term at app. 35% i long term at max. 25%.), leackage

reduction in network, improvement of operational stability, increase of

capacity of water tanks.


CHALLENGES - WASTE WATER

SEWERAGE IMPROVEMENT OF EXISTING SEWERAGE SYSTEMS

WASTEWATER TREATMENT

STATUS: Connection at WW system not compliant with Council Directive

91/271/EEC.

STATUS: Bad condition of part of existing network (14 km),

improvement of existing wastewater system aiming to reduce the

infiltration of subterranean waters and sea and discharge of WW in

underground.

STATUS: Existing WWT not compliant with Council Directive

91/271/EEC

TARGET: To achieve the compliance with 91/271/EEC by increase of

connection to public sewerage at 97%.

TARGET: To improve the existing network in order to minimize the a.m.

pollution risks.

TARGET: To achieve compliance with 91/271/EEC by upgrade of WWTP at II

grade.

Systematic construction of sewerage system Split- Solin started

1997. with puting in function following facilities:

Part of plant Katalinića Brig with crude and fine grid and

undersea discharge (L= 1.300 m; DN 800 mm);

Part of WWTP Stupe with mechanical pre-treatment (crude

and fine grid, aerated sand- and grease catcher, and undersea

discharge (dužine L= 2.750m; DN 1000 mm);

Hydrotechnical tunnel Stupe, (L= 2.512 m , 2 pipes: DN 1200

mm).

Main PS wastewater systems within this agglomeration are:

o Dujmovača (kapaciteta Qmax= 595,0 l/s)

o Šine (kapaciteta Qmax= 240,0 l/s)

o Solin (Qmax= 280,0 l/s).

Entire wastewater system od Split-Solin agglomeration consists of

8 catchment areas.
