ABSTRACT. –Assessment of water demands in the rural settlements of the Someşan Plateau. Through this paper we have evaluated four different water demand calculations, which would allow the development of water supply strategies on a short, medium and long term. Judging by the second variant of calculation the total water needs of the localities, from the Someşean Plateau, ranges from 40,9 l/s, for the first variant, to 199,4 l/s, in case of the second variant. Water demand was estimated at administrative level (district, commune and localities), for the main river basins and their related sub-basins, and also on a geographical sub-units level. Regardless of the variant we used when calculating the weight of units or analyzed subunits, this remains the same. For example, the Cluj County holds 66.5% of the necessary water in the Someşean Plateau, followed by the counties of Sălaj and Maramureş with 28.8% and 5.7%. The river basins of Someş and Someşul Mic represent approximately equal weights (48.3% and 48.6%), while the basin of Lăpuş is defined by a very small percentage. The share that defines different administrative subunits, either geographical or hydrographical, depends on the area, density and size of the related localities. The share of water that belongs to each geographic subunit from the Someşean Plateau ranges between 33.8% (in the Cluj Hills) and 6.3% (in the Sălătruc Hills). The water volumes required annually by the Someşean Plateau localities oscillates between 1288 m3, in the first case scenario and 6281 m3 in the fourth case. So, the evaluated water volumes should be decreased, on average, by about 30%, depending on the specific circumstances of the territories studied by taking into account the unfavorable position of some towns to the main hydrographical course, the size of settlements, as well as the opportunities of their future development.

Key words: water necessity, specific water consumption, Someşean Plateau, rural settlements
