Terminy remontów instalacji wodociągowych, kanalizacyjnych, centralnego ogrzewania są często przesuwane w czasie, co skutkuje awariami instalacji i większym zakresem prac remontowych w budynku. W artykule przedstawiono analizę skutków przesunięcia terminów remontów instalacji na zmianę stanu technicznego budynku. Uzyskane wyniki wskazują na konieczność terminowego prowadzenia prac remontowych również ze względu na zwiększającą się ilość odpadów budowlanych i wprowadzane ograniczanie ich ilości.

The repair deadlines for water, sewerage and central heating installations are often postponed, resulting in installation failures and more extensive repair work in the building. This paper presents an analysis of the effects of postponed installation repairs on changes in the technical condition of the building. The results obtained show the necessity of timely installation renovation works due to the increasing amount of construction waste and the introduced reduction of waste with increasing recycling rates.

The article presents the current state of knowledge in the field of estimating preliminary values of storm water subcatchment calibration parameters in the case of using the Storm Water Management Model (SWMM) for building a model of storm water drainage system. The key issue is estimating the runoff width in the case of reducing the network structure and storm water catchments due to the shortening of calculation time and simplification of the model calibration process. Correction of one of the recommended literature methods has been proposed. The assessment was based on the real catchment model with single and multi-family housing. It was found possible to apply the proposed method in the case of reducing systems connected in series.

The article presents issues related to modeling of the rainfall-runoff phenomenon. As factors influencing the simulation results, the velocity and direction of precipitation relative to the drainage basin were indicated. The possibility of underestimating the crosssections of rainwater channels as a result of overlapping rain wave directions and the dominant flow direction in the rainwater channel network was pointed out. The research results to date indicate a reduction in the symptoms of this phenomenon as the complexity of the channel network increases. The final verification was based on the actual catchment. Calculations were made using the Epa SWMM 5.1.013 software. The results are presented in a graphic form to illustrate the variability of stormwater outflow.

Water consumption is an amount characteristic to individual water sup-ply systems. It is described by values of the unitary consumption of water and unevenness coefficients. An analysis of consumption for the years 2009-2016 in two systems which are diverse in terms of the number of supplied recipients as well as the intended water use is presented. The values of unitary consumption indices as well as hourly and daily irregularity of consumption were calculated, and factors influencing the irregularity of consumption in different time frames indicated. Conclusions regarding the amount and irregularity of consumption were drawn and compared with guidelines and other analysed systems.
