
Central Area largely served by
combined sewers.
Leakage from old sewers
causing pollution.
Western area served by
combination of septic tanks and
direct discharge to land.
Eastern area largely served by
septic tanks.
No wastewater treatment
facilities.




Centralna zona uglavnom se
sastoji od kombinovane
kanalizacione mreže.
Curenja iz starih kanalizacionih
odvoda što uzrokuje zagađenje.
Zapadna zona se sastoji od
kombinacije septičkih jama i
direktnog ispusta na zemljište.
Istočna zona uglavnom se služi
septičkim jamama.
Ne postoje postrojenja za
tretman otpadnih voda.
