In the performed research, the variability of sewage inflow to the Wastewater Treatment Plant in Bielany during dry and wet weather in different years and months in the period of 2008–2012 was analyzed. Particular attention was paid to the problem of accidental water which inflows to the sewage system in Bielany. Considering the period of observation, the hydraulic capacity of wastewater treatment plant was most frequently exceeded in 2010 (172 cases), least frequently in 2012 (54 cases). The probability of the appearance of daily sewage inflows, which exceed the hydraulic capacity of wastewater treatment plant in the period between 2008 and 2012 was 42%. The performed research has shown that, after eliminating the inflow of accidental water to the sewage system, the average-daily hydraulic load would not exceed 78.1% of the designed
hydraulic capacity.

In the paper the results of experimental research on the deterioration of drinking water quality after cement mortar lining were presented. The experiments were conducted in the renovated water pipeline section in Cracow. Based on the results, the expected degree of leaching of the pollutants from cement mortar to drinking water for specified lengths and diameters of renovated pipes, as well as water velocities, was estimated.

https://doi.org/10.4467/2353737XCT.16.198.5947The paper presents laboratory experiments on the influence of different hardness water samples collected from the municipal water supply system on the intensification of leaching pollutants from the internal cement mortar pipe lining to drinking water. The paper presents the analysis of water quality indices, such as pH, aluminum and selected heavy metals concentrations after contacting with cement coatings.
