Abstract: Pollution of surface (rain) wastewater forming in the production territory of a pig-breeding enterprise was investigated in the period 2007–2011. The surface water is collected from the production territory from yards with a hard covering and from roofs, enters the rain sewerage, and is released untreated into the natural environment. The aim of this work is to find out what influence on the environment is exerted by surface wastewater released into the natural environment from the production territory of pig-breeding enterprises. Surface wastewater pollution indices and the research frequency were identified according to the requirement to carry out surface water monitoring: surface wastewater samples are collected three times per year. Because of the uneven rainfall distribution during the year, less surface wastewater runoff occurred during the cold period; however, concentrations of indices were higher compared to the end of the warm period (TSS – 18 %, BOD7 – 39 %, Ntotal – was unchanging, oil products – 12.5 %). Only Ptotal concentrations were higher in the end of the warm period in 14 %. The organic pollution in surface wastewater was increased by total suspended solids. The increased concentrations of TSS and biochemical oxygen demand (BOD7) were related to a higher precipitation level. The indices’ TSS, BOD7, Ntotal, Ptotal and oil products concentrations in the surface wastewater runoff from the pigbreeding enterprise‘s production territory complied with the requirements for surface water which is collected from this area and released into the environment
