The article presents an analysis of an existing water supply system. Water consumption in various time frames, i.e. a year, week and 24 hours, is shown. A hydraulic model was developed and, using the EPANET programme, calculations simulating its parameters carried out, accounting particularly for water age, which reflective of the water quality supplied to the recipients. The obtained results are the basis for assessing the operation of the system.

Network Status

Under the existing technical and financial conditions, we can not do real-time monitoring of the water supply network in each point. The hydraulic model establishment has created favorable conditions for simulating pipe network hydraulic model.According to the information from pressure monitoring point of water supply pipe network , we can use batch adjustment principle to analyze the calculated variables’ value. With limited resources to simulate real-time network status, build pipe water conservancy network model and simulate network real-time operating conditions. Hydraulic model provides the basis for the water supply network security evaluation, scheduling scheme, pumps and piping renewal.

This paper presents an analysis of the operation of the water supply system. The analysed network provides water to six small towns. The water supply network covers rural areas of approximately 50 square kilometres with a total of 6130 inhabitants (2020). The area is characterised by relatively large differences in elevation. The water-pipe network supplies water mostly to family housing, public utility buildings, recreational buildings, service and craft entities, religious buildings, and commercial facilities and farms, including breeding farms. The network is supplied from one deep water well and a centrally located water supply tank. A hydraulic model was used for the analysis. The model was developed using the Epanet program, based on numerical and operational data. After validation, selected measurement points were used to calibrate the model. Furthermore, a series of simulations were performed to illustrate the network operation for variable water supply and demand conditions. Single-period analysis was used for modelling due to the type of data obtained. The model allowed for the determination of the head of pressure in the network points and flows in particular sections for the operation parameters studied. The analysis showed that at present, the network is not operating stably. In the case of average demand, water is supplied to all users, but there are areas in the network characterised by high pressure. On the other hand, during maximum water demand, due to the limited water supply to the water reservoir, from which most of the network is supplied, there are water deficiencies that cannot be compensated for by the operating pumping system.

Comprehensive Study

Some forms of organic matter existing in the water have direct or indirect effects on microbial growth. By the investigation data over drinking water and reclaimed water, we summarized organic limiting factors that may affect the growth of microorganisms and factors affecting these water qualities in the reclaimed water supply network, such as a variety of treatment process and the residual disinfectants. Through its comprehensive study, we want to make a contribution of opinion to control the growth of microorganisms in reclaimed water supply network.
