Abstract

Crpilište Velimirovac predstavlja zdenački zahvat podzemnih voda, te je najvažniji faktor u vodoopskrbi grada Našica i okolnih naselja. Crpilište se sastoji od četiri bušena zdenca, pojedinačnog kapaciteta od 40 l/s. Podzemna voda crpi se iz dravskog aluvijalnog vodonosnika koji je izgrađen od sitno i srednjezrnatog pijeska i nešto šljunka. Napajanje podzemnih voda u ovim predjelima je pod dominantnim utjecajem vertikalnih čimbenika vodne bilance. Naime, infiltracija oborina je jedini izvor stvarnoga obnavljanja vodonosnog sustava koji je zahvaćen na crpilištu Velimirovac. Visina srednjih godišnjih oborina se kreće oko 800 mm. Vrijednosti hidrogeoloških parametara vodonosnika na crpilištu Velimirovac istraživani su u sklopu izvješća o rezultatima izvedbe pojedinih zdenaca. Kemijske analize pokazale su da su vode pretežito kalcijsko-hidrokarbonatnoga facijesa, no uz mjestimice povećanu nazočnost iona magnezija.

Abstract: The well field Velimirovac represents the main source of water supply system for the municipality of Našice and its surroundings. The well field includes four wells with a 40 l/s capacity. The water is extracted from the alluvial aquifer, composed mostly of fine and middle grained sand and some gravel. Vertical water balance factors are dominant in the aquifer supply. Infiltration is the only source actually restoring the aquifer. The average annual rainfall is approximately 800 mm. The hydraulic parameters values were investigated as part of the report regarding wells performance. Water chemical analysis revealed Ca(HCO3)2 facies with occasional magnesium presence.
