Tirana River is one of the main branches of Ishmi river and serves as collector for wastewater discharge, for the capital city and its surrounding rural areas. This river created  the north administrative border of Tirana and it’s formed from mountainouse conflux in Zall-Dajt area. Besides increasing the amount of sewage discharge into the river, as a result of population growth, it is a fact that in Tirana river solid waste from non-responsible businesses and different urban wastes are being deposited. The purpose of this study is to assess the microbiological quality of Tirana river by collecting reliable information about conditions in different area wherever the river course outside and inside the Tirana city. Samples were taken at four different points during year 2012-2013. The river is tested for indicators of pollution such as Streptoccocus faecali  and Escherichia coli as well as the presence of actinomycetes. Microbiological contamination tests show relatively large water contamination, especially in three areas where the river passes in residential area. Bacteria are transported to the River via storm water, catch basins, sediment, runoff, discharges, and spills. Larger amounts of bacteria reach the river when surrounding lands are more highly developed or "urbanized." The high level presence of these microorganisms indicates that the water quality of the river is very bad according to standards, presenting a risk to health of all the organisms that inhabit the sweet waters. River areas in considerable distance from residential areas, show microbiological level lower than in those close to residential areas. It is noticed also, a growth of temperature and TDS. This growth was more evident during raining days for TDS and temperature during drought periods of monitoring.
