Abstract:

Introduction. The practical operation of water supply networks, made of steel and gray cast iron, has proven that deposits accumulate on the inner surface of pipes under certain conditions. Deposition depends on the quality of transported water and the water flow regime, same as in gravity sewerage networks. A sediment layer accumulates in the flume of pipes if the actual flow rate is smaller than the minimum standard one. A layer of deposits in metal water pipes changes the value of the actual inner diameter of pipes and rises the pressure loss due to resistance along the pipeline length, whi

Groundwater seepage through cracks in the sewerage pipeline is a major maintenance issue in most cities’ sewer networks. The more the sewer pipes crack – and the wider these cracks are – the worse the rainfall seepage problem becomes. The total volume of rainwater seepage into the sewer pipes for a catchment is correlated with deterioration and can therefore be used to estimate the rate of deterioration. This paper describes a monitoring system that can be used to identify significant trends in sewer deterioration. Effective monitoring by asset managers can highlight the need for early mainten

Abstract:

Urban areas exercise numerous and strong pressures on water bodies, implying that different external anthropogenic factors also stress groundwater. Sewerage networks play an important role, being the place of wastewater flow. When sewerage deterioration conditions occur, aquifers can be contaminated by contaminants contained within wastewater. The study aims to verify the impact of sewerage leaks in urban semi-confined aquifers through a multidisciplinary approach. Geological, hydrogeological, hydrochemical, microbiological, and biomolecular investigations are carried out in a test site close

Abstract:

Problem statement. The most expensive and vulnerable part of the city's engineering infrastructure are pipeline systems that divert wastewater from the settlement. The state of the environment, the efficient operation of the city's enterprises, and the comfort of the citizens living directly depend on their uninterrupted operation and the level of reliability. Thus, the primary task of utilities is to ensure the reliable performance of sewer networks. When repairing and restoring large-diameter sewer pipelines that transport wastewater by gravity, the actual task is the choice of materials tha

Abstract:

Modelling of stormwater networks and the related object (combined sewer overflows, diversion chambers, retention tanks) is a complex task requiring colleting of data with appropriate time and spatial resolution as well as application of adequate models. Often there is a need to find balance between the costs of conducting measurement (period, resolution) and the uncertainty of the model results. This paper presents an overview of simulation tools for sewerage networks modelling, related objects, as well as low-impact development (LID) systems in relation to the hydrodynamic and statistical mod

Abstract:

In recent years, stormwater drainage systems have not been able to cope with the volumes of surface runoff that are formed in settlements. This leads to significant flooding of urbanized areas. An effective solution can be the inclusion of rainwater control structures in the stormwater drainage systems. But this solution requires clarification in hydraulic calculations. The method of temporary interception stormwater at places of their precipitation with infiltration basins is reviewed. Infiltration basins are used to reduce the peak load on existing stormwater sewerage facilities, prevent the

Storm water management in urbanized areas is currently a global issue. In order to verify the correct functioning of the sewer networks and their objects, it is necessary to regularly assess their hydraulic capacity. Key of assessing the capacity of single and rainwater sewer networks is the calculation of the amount of surface runoff and the selection of a suitable design rainfall model. This article deals with the issue of effective decision making in the choice of the design rainfall for the hydraulic assessment of the sewer systems.

The article explores the mechanism for implementing Public-Private Partnership (PPP) in the water supply and sewerage sector in Ukraine. Reliable and uninterrupted water supply and sewerage services are critical components of any country’s infrastructure. However, Ukraine faces significant challenges in this sector, including outdated infrastructure, high operational costs, and insufficient investment. The study highlights the urgent need for modernization and identifies PPP as a key instrument for attracting private investments and innovative technologies to improve infrastructure efficiency.

Introduction. It is widely known that the operation of sewage treatment facilities requires a significant amount of energy, consumed by the pumping equipment, the automated control system, lighting, heating, ventilation, etc. To ensure the reliable operation of pressure sewerage pipelines, it is necessary to analyze the flow parameters and adequately protect these structures from pressure surges (fluid shocks), that demonstrate unique features in the process of wastewater discharge. The proposed method of analyzing principal hydrodynamic parameters in case of a fluid shock takes into account t

Abstract:

Managing sewerage systems is a highly complex task due to the dynamic nature of the facilities. Their performance strongly depends on the know-how applied by the operators. In order to define optimal operational settings, two decision support tools based on mathematical models have been developed. Moreover, easy-to-use interfaces have been created as well, aiding operators who presumably do not have the necessary skills to use modelling software. The two developed programs simulate the behaviour of both wastewater treatment plants (WWTP) and sewer network systems, respectively. They have essen
