Water Supply Network

In this study, we investigated the modelling and optimization of drinking water supply system reliability in the village of Zaben, Czech Republic. An in depth overview of the water supply network in the municipality, passport processing and accident and malfunction recording is provided based on data provided by the owner and operator of the water mains as well as the data collected by our own field survey. Using the data processed from accident and failure reports in addition to water main documentation, the water supply network in Zaben was evaluated according to the failure modes and effects analysis methods. Subsequently, individual water supply lines were classified based on their structural condition. In addition, a proposed plan for financing the reconstruction of the water supply mains in Zaben was created. As such, this study provides an overall assessment of the water supply network in Zaben alongside a proposed plan for the structural restoration of the water supply system, which accounts for the theoretical service life of the system and the financial resources of the owner.

In this paper,the assimilable organic carbon (AOC) and the total number of colonies were deterimined for studying the effect of Ultraviolet (UV) disinfection of drinking water at Dianliu Pressure Station, Jinan City. The result showed that the total number of colonies on average decreased 28.7% campared with the initial values. However, the value of AOC increased 47.6%, 83.8 % and 181.9 % after UV disinfection power strengthened. Therefore, the application of UV disinfection of drinking water still need further study to evaluate the disinfection effect.

Quality changes of drinking water in the water supply network (case study from Lithuania) The purpose of this research was to examine water quality changes by distributing in to the water supply network. Water samples were collected from Varena town (Lithuania) drinking water distribution system fed by groundwater from well field. Parameters related to undesirable increasing of nitrites and nitrates concentrations have been measured considering these samples: pH, conductivity, concentration of total iron, manganese, ammonium, nitrates and nitrites. Results showed that groundwater from well field were extremely susceptible to favor bacterial growth in the pipelines. The occurrence of nitrites and nitrates in drinking water samples correlated positively with the lengths of old iron pipelines and negatively with the content of newly laid pipelines. The obtained results also showed that the potential nitrates increasing induced by the distribution of treated water could be reduced if: nitrates levels were below detection limits at the outlet of the water treatment plant; biological ammonium removal treatment implementation should reduce the levels of the nitrates and nitrites of the treated supplied water. Although the nitrates concentration increase in drinking water distribution systems, the issues with nitrites accumulation are rare in Lithuania. However, such processes still need to be proved in more extensive investigation, but these research results could be applied as a basic scenario.

Švihov dam, the largest drinking water source in the Czech Republic and Central Europe, has problems with eutrophication. The Švihov dam catchment spreads over 1200 km<sup>2</sup> and supplies over 1.5 million people in the capital of Prague and the Central Bohemian region with drinking water. Due to intensive agricultural activities and a lack of wastewater treatment plants in small settlements, the water quality is deteriorating. As a result, corrective measures need to be taken. Technological Agency of the Czech Republic supported this research which proposes different scenarios for a reduction of water quality degradation in the dam. The Trnávka dam watershed was chosen for study purposes as it occupies one quarter of the Švihov dam watershed. Hydrological balance was established using measured data. Point and non-point sources of nutrients were determined by field research and included in a Soil and Water Assessment Tool (SWAT) model. This study aims to propose complex watershed management to improve the state of the environment in the entire area and to reduce eutrophication. Different management practices would reduce nutrient loads of streams and increase water quality which is the critical factor in dam eutrophication. This research brings methodology and systematic approach to integrated management, and can be applied not only for the Švihov dam, but also for other watersheds, including those which function as drinking water supply.
