SPAM (Sistem Pengolahan Air Minum or Drinking Water Treatment System) UNS was established in 2015 to meet the drinking water needs of the UNS academic community by providing 129 dispensers and water tap machines spread across buildings at UNS. A survey conducted by UNS students in 2017 showed that 54 % of students were not sure of the quality of UNS SPAM water. So the service quality questionnaire was distributed to 160 UNS students randomly and it was found that only 3 % of respondents stated that they used SPAM UNS water dispenser very often. Processing results shown the highest gap value is in the reliability dimension, with CTS namely cleanliness and flow of water. From the survey regarding the cleanliness and flow of the water carried out the DPMO value of the process was 332,589 (1, 930 sigma) . Recommendations for improvement are in the form of several SOPs to improve the cleanliness and quality of SPAM UNS water dispenser services.

The possibilities of using natural granular glauconite in standard water treatment schemes have been investigated. Resource tests of the studied material were carried out in dynamics, simulating possible conditions of use. As a result of the experiments, it was established: during the filtration process, alkalization of water occurs, but the result does not exceed pH = 6÷9, which are the norm for drinking water; the use of a sorbent based on natural glauconite does not impair the hardness indicator of the treated water. The dynamic exchange capacity was: for iron – 3.09 mg/g of absorbent, copper – 19.15 mg/g of absorbent, zinc – 4.82 mg/g of absorbent. The resource of the filter was determined with the loading of granulate with a volume of 1 dm3: for iron – 2918 dm3, for copper – 5425 dm3, for zinc – 273 dm3. The mechanical strength acquired by the sorbent as a result of granulation made it possible to wash the load by the countercurrent method, freeing intergranular pores from the sediment accumulated in them. The revealed capabilities of granular glauconite will allow its use in drinking water treatment schemes for purifying natural waters from heavy metals: iron, zinc, copper.

Safe source of drinking water is always considered as an essential factor in water supply for cities and urban areas. As a part of this issue, drinking water quality is monitored via a useful scheme: developing drinking water quality index DWQI. DWQI is preferably used as it summarizes the whole physicochemical and bacteriological properties of a drinking water sample into a single and simple term. In this study, an evaluation was made for three drinking water treatment plants DWTPs named: Efraz 1, Efraz 2 and Efraz 3 that supply drinking water to Erbil City. The assessment was made by testing thirteen physicochemical and two bacteriological parameters during a long period of (2003 – 2017). It has been found that turbidity, electrical conductivity EC, total alkalinity, total hardness, total coliform and fecal coliform have more influence on drinking water quality. DWQI results showed that the quality of drinking water supplied by the three DWTPs in Erbil City fallen within good level. Except various occasional periods where the quality was varying from good to fair. The quality of the drinking water supply never reached the level of marginal or poor over the time investigated. The applied hierarchical clustering analysis HCA classifies the drinking water dataset into three major clusters, reflecting diverse sources of the physicochemical and bacteriological parameter: natural, agriculture and urban discharges.

To guarantee drinking water of high quality not only the drinking water treatment must be of high standards but also the quality of water resources should be the best possible. Therefore, pollution control and pollution risk management in the catchment areas of water resources are important parts of an overall water management concept. This includes the assessment of physical and chemical parameters as well as bacteriological parameters, especially hygienic parameters. A concept for an integrative consideration of drinking water treatment and quality management of water resources is presented.
