A graduate of Environmental Engineering at the Poznań University of Technology, she has been involved in trenchless technologies since the beginning of her professional career. She gained experience at Terlan as a construction engineer, where she was responsible for the formal and legal aspects of investments involving sewerage network renovation technologies.
The next stage of her professional career is connected with the Investment Department of AQUANET, where since 2017 she has been managing projects related to the renovation of water supply and sewage systems, as well as large infrastructure projects in the city center, covering both of these systems.
For a year, he has been the leader of the team responsible for designing and implementing renovation tasks, investments in rainwater management, and projects carried out in cooperation with the City of Poznań and other municipal companies.

The presentation addresses an issue that an increasing number of designers and contractors involved in trenchless works are encountering in practice – the lack of space to apply available technologies. In conditions of dense urban development, narrow road lanes, extensive underground infrastructure, and limited access to wells, it is increasingly not the technical parameters of devices, but their dimensions that determine the feasibility of an investment.

The presentation will discuss why many commonly used trenchless technologies require space that is often unavailable in urban environments, and what consequences this has for the design and construction phases. Particular attention will be paid to situations where classic solutions are no longer possible, not for technological reasons, but purely for geometric ones.

Against this background, a technological approach based on maximum reduction of the dimensions of the device and working facilities will be presented, enabling work to be carried out directly from well to well. The presentation will show how compactness is becoming a key technical parameter influencing the ability to maintain precision, work safety, and compliance with design specifications.

Instead of comparing technologies in terms of power or performance, the presentation will focus on the actual field conditions in which the technology must fit—not the other way around. Examples will be presented of locations where limited working space determines the choice of a trenchless method or leads to the need to seek non-standard solutions.

The presentation is technical and problem-oriented. Its aim is to show that in modern infrastructure construction, innovation increasingly involves adapting technology to the site of implementation rather than increasing the scale and size of equipment. Kompaktowość została tu potraktowana nie jako cecha marketingowa, lecz jako konkretna odpowiedź na ograniczenia, z którymi branża mierzy się na co dzień.

The renovation of large-diameter collectors, characterized by large diameters or significant cross-sections in the case of non-circular profile channels, is one of the most demanding technical and technological challenges in the operation of sewage systems. This is due, among other things, to the limited availability of specialized trenchless technologies, the need to carry out work in difficult spatial conditions, and high health and safety requirements during work carried out on an active sewerage network.

Significant structural loads, often large foundation depths, and varying technical conditions of structures require an individual design approach, close supervision of the works, and precise quality control at every stage of the renovation process.

An additional challenge is the need to maintain continuity of sewage collection throughout the entire period of the works, which often involves the construction of complex bypasses or, if the technology used allows it, carrying out works “under flow.” Renovations of large-size collectors are usually carried out in dense urban areas, under streets and transport routes, often while maintaining active vehicle traffic, which significantly increases the complexity of the work and organizational requirements.

In the case of combined sewers, an additional aspect is ensuring reliable wastewater collection during rainfall, which requires taking into account variable and often very high flows throughout the entire renovation process.

Trenchless renovation of sanitary engineering facilities based on PREDL technology and methods provides modern, effective, and durable solutions to problems related to the technical degradation of sewerage networks and facilities. These methods allow for the rehabilitation of existing infrastructure without the need for excavation, which significantly reduces interference with existing infrastructure, lowers costs, and shortens the time needed to complete the investment.

The basic measure ensuring the efficient functioning of sewer pipes is their periodic cleaning. This allows for maintaining hydraulic efficiency and enables a proper assessment of the technical condition during inspections. The paper will present the results of research aimed at introducing a cleaning strategy based on operational experience and knowledge of the condition of the sewerage network. The optimization of cleaning intervals is aimed at reducing costs, as unnecessary sewer cleaning is eliminated.

Water supply connection failures are a growing challenge for operators – in many systems, their number already exceeds the failure rate of distribution networks, and water losses are difficult to locate and repair. The most common types of damage, such as internal and external corrosion or pipe breaks, result from both the quality of materials and workmanship, as well as processes occurring during operation. Accumulated deposits of iron, manganese, or calcium gradually reduce the diameter of the pipes, lowering their transmission capacity. At the same time, progressive corrosion processes lead to a weakening of the pipe structure and an increased risk of failure.
The paper will present current data on the technical condition of connections and the most common causes of their damage. The expert will discuss why, in many cases, it is more cost-effective and efficient to use trenchless technologies instead of traditional open trench replacement. Participants will learn about the key criteria for selecting the right method – from technical and economic to social and environmental – and how proper diagnostics and analysis of the condition of the connection influence further operational decisions.
The presentation will also provide an overview of the most important methods of renovation and trenchless replacement, including the installation of various types of linings. Their advantages will be discussed: reduced earthworks, lower risk of interference with accompanying infrastructure, favorable hydraulic properties, and shorter completion times.
The presentation is aimed at water supply infrastructure managers, designers, and contractors who want to make informed choices about connection renovation methods and minimize the risk of failures and water loss. It is a practical summary of knowledge that will help you make more accurate investment and operational decisions.

Wells are a very important part of sewage systems, and the condition of the entire system depends on their condition. There are hundreds of thousands of wells in a medium-sized city. It is worth knowing how to keep them in full working order. In recent years, new repair technologies have emerged, and previously known ones have been significantly modified. The materials used for renovation often have significantly better parameters than those used to construct the wells. Thanks to new materials and technologies, repair times can be significantly reduced. Thanks to the innovations introduced, the well repair process will become better, faster, and cheaper.

CIPP (Cured In Place Pipe) is currently one of the most commonly used methods of trenchless renovation of sewer and water pipes. Its dynamic growth is driven not only by technological advances, but above all by the measurable economic and environmental benefits compared to traditional open-pit mining methods. The paper will present a comprehensive analysis of these benefits, covering both the direct costs of the works and the indirect costs incurred by infrastructure managers and users of public space.

In terms of economic benefits, we’ll talk about how CIPP tech can cut down on project time, reduce the amount of earthworks needed, lower resurfacing costs, and minimize traffic and environmental disruption. Attention will also be drawn to the possibility of extending the service life of existing pipes at a relatively low investment cost and to the favorable cost balance over the entire life cycle of the facility (LCC).

The conclusions from the analyses confirm that CIPP technology is an effective solution both from the point of view of investment economics and environmental protection, especially in densely built-up urban areas and with growing requirements to limit the negative impact of construction works on the environment.
