The construction of the replacement well Z-15/3 in the Vinogradi well field, Osijek : master's thesis

Zdenac Z-15/3 na crpilištu Vinogradi, Osijek izveden je kao zamjenski zdenac zdenca Z-15 nakon što revitalizacija više nije bila učinkovita. Radovi na izvedbi zdenca provedeni su početkom 2020. godine, a izvođač je Vodovod – Hidrogeološki radovi d.o.o. Osijek. Starenje zdenaca na crpilištu Vinogradi uzrokuju oštećenja izazvana karbonatnim inkrustatima, ''navlačenje'' glinovito-siltoznih frakcija tijekom eksploatacije te organski talozi nastali djelovanjem željezovitih bakterija. U ovom diplomskom radu su prikazane osnovne značajke vodocrpilišta Vinogradi, koraci izvedbe zdenca Z-15/3 te su izračunati parametri zdenca iz podataka dobivenim pokusnim crpljenjem s promjenom crpne količine tijekom crpljenja.The well Z-15/3 in the Vinogradi well field, Osijek was constructed as a replacement well after rehabiliation was no longer effective. Works on the construction of the well were carried out in early 2020 and the contractor was Vodovod - Hidrogeološki radovi d.o.o. Osijek. Deterioration of wells in the Vinogradi well field is caused by damage created by carbonate incrustates, mobilization of fine fractions during pumping and organic precipitates created through the action of iron bacteria. In this thesis the basic characteristics of the Vinogradi well field and the steps of the construction of the well Z-15/3 are shown. Also, the parameters of the well are calculated from the data obtained during a pumping test
