Abstract: The water is one of the major components for the sustainable development of biggest companies even though its impact in the industry of cement in Sharrcem-Hani Elezit-Kosovo is relatively small compared to the other sectors. The priority of water management efficiency emerged at the World Business Council for Sustainable Development Initiative (WBCSD/CSI). The Sharrcem cement plant in Hani Elezit, Kosova except other investment on environmental improvement recently has installed Waste Water Treatment Plant (WWTP) which have been in service, since, the beginning of 2016 a serious investment whose purpose was to improve the quality of the polluted waters prior to discharge into the Lepenc River to prevent potential water pollution to protect the environment and the health of the employees of Sharrcem and of the local community. The waste water treatment plant operates with the latest technology according to serial reactors (Sequencing Batch Reactors-SBR) with a fully automatic system and a capacity of 500 equivalent residents where a number of local residents of the city Hani i Elezit are connected. The application of new technologies in WWTP is showing high results in the quality of treated water, compared to the previous state of the plant where the wastewater was unloaded directly untreated in the Lepenc River flow. The polluted water quality analysis in industrial operators is estimated through the main parameters of pollution such as: potassium bacteria with fecal origin, Biological Oxygen Demand for 5 days-BOD5, Chemical Oxygen Demand-COD, Suspended Solids-TSS and pH value as well as other physico-chemical accompanying parameters such as, the presence of various metals, sulfate groups, nitrate groups, etc. From the monitoring results for 2016 and 2017, it appears that the pH value is within the allowed values while solid suspended chips TSS, after treatment are able to drop threefold below the allowed values for the flow of waters. The Chemical Oxygen Demand-COD and the Biological Demand for 5 days Oxygen-BOD5, after treatment reaches tenfold below the allowed values according to the required standards. Positive encouraging results were also demonstrated in the monitoring of other physical and chemical parameters which after treatment fell below the limit values, before discharging polluted waters in the Lepenci River. The water quality monitoring results at the plant show that, the water which comes out of the Waste Water Treatment Plant (WWTP) and is discharged into the Lepenci river meets and exceeds multiple quality requirements in accordance with EU and national standards for wastewater discharge values. (Kosovo Water Law No 04/L-147 and Administrative Instruction No. 30/2014 on the conditions, methods, parameters and limit values for the discharge of waste water into the public sewage network).
