POVZETEK

V članku primerjamo tri variante preskrbe obalnega območja in Krasa s pitno vodo, in sicer:

I. Regionalni primorski vodovod z vključitvijo vodnih virov Rižana, Malni in po potrebi akumulacije Padež.

II. Vodovod z vključitvijo izvira Rižane in akumulacij na Notranjski Reki.

III. Ojačitev kraškega vodovoda z zgraditvijo akumulacij nad obstoječim izvirom Rižane.

Po izčrpni, posebno hidrološki predstavitvi vseh variant smo prišli do sklepa, da je za realizacijo najprimernejša I. varianta z zajetjem izvira Malni pri Planini.

SUMMARY

The article compares three variants of water supplies of the coast and the Karst region with the drinking water, namely:

I. Regional littoral waterworks with the inclusion of the water sources Rižana, Malni and, when needed, water retention Padež.

II. Waterworks with the inclusion of water source Rižana and the water retentions of the river Notranjska Reka.

III. Strengthening the waterworks of Rižana with additional retentions above the existing water source Rižana.

The exhaustive, specially hydrological presentation of all variants, led us to a conclusion, that the most appropriate for realisation, is the I. variant, with the inclusion of the water source Malni at Planina.
