The calculation model and selection of the strength parameters of the CIPP liner – guidelines DWA-A 143-2
Speech deals with the issues of selection suitable boundary conditions for a technical condition of the pipeline. Properly set output parameters determine the course of the design process and the relevance of the solution – in this case the appropriate CIPP liner. The leading issue is to analyze the process of determining the strength characteristics which is basis on the guidelines DWA-A 143-2. The main stage of the design process is to analyze the stability of the pipeline-lining CIPP. The basic condition which allow appropriate selection of parameters is proper assessment of the pipe technical condition. Properly executed project should ensure optimization of both the economic and construction of the proposed solution.

PAPER 1.: Sewerage rehabilitation with UV-cured lining. Equipment evolution in the last decade
The recent decade has seen an intense progress in the development of the equipment for installation of UV-cured lining materials. It is also in line with the expectations of customers and investors who are increasingly turning to this technology. In 2006, the largest diameters of UF-cured sleeves offered by suppliers as a standard were up to 1,200 mm,while now installations of 1,800 mm in diameter are known. What else has changed in the recent years?

The water supply and sewerage company as a non- commercial contractor of sewer repairs in the CIPP technology using the liners impregnated with epoxy resins
The author of this paper will present insights on their own and non-commercial contracting for sewersrenovation works in the CIPP technology, realized by the native water supply and sewerage companies. The study covers technological and organizational aspects of installing the liners impregnated with epoxy resins, carried out independently by the Polish water companies.

CIPP in Poland and Europe
CIPP is the most important rehabilitation technology for sewer systems worldwide. This is due to the flexibility of the half-fabricated product, which is finished on site while using different hardening methods.
The market situation in European countries differs. The technology is highly used in central, western and eastern Europe; highly developed markets are Germany, France, BENELUX, Poland and Czechoslovakia.
Approximately 2 000 000 km of public sewers are laid in the grounds of Europe. And with an estimated damage rate of minimum 20% about 400 000 km have to be renewed.
Let’s have a closer look on some markets like Germany, France, Poland, Czech Republic and Slovakia.

The main differences in terms of liners’ dimensioning according to the guidelines ATV-M 127-2, 2000 and DWA-A 143-2, 2015
After 15 years after the releases guidelines ATV-M 127-2, a German technical organization DWA decided to replace it with the new study, designated as a guideline DWA-A 143-2. Keeping the main principles of the computational approach, the new guidelines have a number of differences, which are worth to discuss due to the high popularity of the older studies. The conversance of the previous guidelines may help to solve the cases previously. Or it can give the effect in more precise calculation results, leading ultimately to make savings, e.g. due to the thickness of the liner.
