Project of the year – renovation

Aarsleff sp. z o. o.

As a General Contractor, Aarsleff Sp. z o.o. completed the job entitled “Rehabilitation of the Sewer System in the Zielona Góra Agglomeration” that was a part of the “Wastewater Management in the Zielona Góra Agglomeration Stage 5”.
The whole investment was made up of nine stages of implementation and the rehabilitation covered over 4,200 m of combined sewer system 100 wells and sewer chambers and almost 200 sewer laterals within the range of circular sewers of DN200mm – DN1600mm and egg-shape sewers featuring the following height/width dimensions: 900/600mm, 1200/800mm, as well as pear-shaped and bell-shaped sewers of the following dimensions: 1600/1200, 2100/1700mm.
Rehabilitation with CIPP liners was applied to complete the job. Subject to the pipe diameter and its functions, a relevant technology was selected to perform the rehabilitation job:
* Dimensions of > 800 mm, water-cured polyester resin liners were applied,
* Dimensions of < 800 mm, water-cured epoxy resin liners were applied,
* Laterals – steam-cured epoxy resin liners were applied.
The most exciting and, at the same time, the most challenging installations completed as a part of this job were as follows:
* Rehabilitation involving installation of CIPP polyester resin liner in the bell-shaped sewer featuring the diameter of 2100/1700 mm at the length of 68 m
* Rehabilitation involving installation of CIPP polyester resin liner in the bell-shaped sewer featuring the diameter of 2100/1700 mm with the change in the diameter (seam) into the diameter of 1700/1700 mm at the length of 70 m
* Rehabilitation involving installation of CIPP polyester resin liner to the egg-shaped sewer featuring the diameter of 1200/800mm in which a 300 m section was rehabilitated as one installation
* Parallel rehabilitation of two sections involving installation of CIPP polyester resin liner to the circular sewers featuring the diameters of 1400 mm and 1600mm, respectively, in the section of the combined sewer
* Construction of a by-pass to drain the sewers made up of two DN250 PE pipes featuring the total length of approximately 500 m with a flyover over the roads in the city. Realistic efficiency of the pumps in the by-pass was approximately 1000 cubic m/h. Pumping operation was performed in the construction site for about three months during rehabilitation of the largest pipes. The project site: old town and one of main roads in the city center
* Construction of a temporary roundabout with a by-pass to drain the sewers made up of two DN200 PE pipes featuring the total length of approximately 900 m. Project site: city center, commercial district

The project involved rehabilitation with a UV cured liner. What is noteworthy is, inter alia, a unique cross-section of the liner – alternative diameter min. DN1600 (maximum DN1730). Four sections (51 m, 66 m, 23 m, and 52 m) were installed making up the total of approximately 192 running meters. The project was implemented in Pl. Piastów, Gliwice.

Completion time: November 2021 – February 2022

Blejkan SA

Burakowski Sewer Collector build in 1960s using the mining technology discharges majority of effluent from the left-bank part of Warsaw. Intense operation of the collector partially damaged it, thus the demand for trenchless rehabilitation.
The project aimed at:
– Ensuring reliable operation of the sewer,
– Reduction of groundwater infiltration and effluent exfiltration,
– Improvement of design strength of the sewer,
– Improvement of hydraulic conditions of effluent flow.
All assumed goals were met as a result of the upgrading work.

The construction work was completed pursuant to the FICIC’s Conditions of Contract in the following formula: “Completion of Assembly Work Pursuant to the Project Documentation Contracted by the Contracting Entity”, so called “Red Book” as a part of the following project: “Water Supply and Wastewater Treatment in Warsaw – Stage 5” based on the “Operational Program Infrastructure and Environment 2014-2020” Project.

Record trenchless rehabilitation in Białystok – DN1800 fiberglass liner. Contracted by Wodociągi Białostockie sp. z o.o. [English: Białystok Water Supply Plant], F.H.U. INSTBUD completed the “Ul. Jana Pawła II – Sanitary Sewer Trenchless Rehabilitation” Project in Białystok.
Several sections of ferro-concrete pipes featuring the diameters of DN500 to the record DN1800:
• 3 x DN500 – 16 m each;
• 2 x DN1000 – 62 m each;
• 1 x DN1800 – rehabilitated in two sections – one 52 m and the other of 72 m,
located under a water course and a two-way road with heavy traffic. This project also involved the rehabilitation of five concrete sewer wells (S1 – 2.4*3.6; S2 – 2.4*3.5; S3 – 2.4*3.5; S4 – 2.5*3.5; S5 – 4.8*5.7).
The most spectacular, and the record event at the national level was installation of the DN1800 fiberglass liner. A liner featuring so large diameter has never been installed in Poland before. In fact one may say that this project broke a double record as a record liner was manufactured in Poland to complete the project. It is noteworthy that the in_liner Production Plant is the only one here that has a capacity to manufacture fiberglass liners featuring diameters of up to DN2000.
In case of this installation, apart from the diameter, the weight of both sections of the DN1800 liner was also considerable. The 52 m section weighed 13.5 tons and the largest and longest section (72 m) weighed as much as 18.5 tons. The operations of unloading and pulling the liner to the channel required additional operational capacity, precision and attention not only due to the weight, but also its dimensions. The size of the shaft through which the liner was pulled in and from which the high-pressure air was pumped into it accounted for an additional challenge.
36,000 Watts lamps were used to cure the DN1800 liner featuring the wall thickness of 19 mm. The lamps were the most powerful ever used in Poland to cure the fiberglass liner. This process was performed at the rate of 60 cm/min. Its progress was monitored and analyzed on an on-going basis by experts located in a special vehicle from which the whole process was controlled. When describing this project, comprehensive rehabilitation of five chambers that made up an important part of this task may not be forgotten. The work was performed simultaneously to the sewer rehabilitation.

InLiner

Renovation liner: in_liner 2.1 DN150-2000

The in_liner 2.1 ECR fiberglass liner is designed for trenchless rehabilitation and sealing circular and non-circular gravity and pressure sewers (DN150 – DN2000) featuring the inner perimeter of 6.2 m. It has a broad range of applications; it is used for rehabilitation of sewers made of concrete, ferroconcrete, clay, fibrous cement, glass reinforced plastic (GFK), PVC-U, PE-HD, cast iron, clinker bricks. The liner is 20 mm thick subject to the liner diameter (a custom-made higher thickness liner is available).
Liner design: reinforced external foil protecting against UV, external layer, resin-glass composite, abrasive layer, internal foil. The liner is resistant to inner pressure and chemicals attack.
Subject to the medium in the in_liner renovated pipe, the liner is saturated with polyester resin (UP) or vinyl-ester resin. It is pulled in and cured in place by means of UV or heat to install. A new structural and sealing layer is generated in the renovated section of the pipe. The curing process is performed by means of professional tools and UV lamp equipment. Upon completion of the rehabilitation project, the internal surface inspection is performed using the TV camera and the pipe water test is performed to check the throughput of the pipe after the rehabilitation.
The in_liner 2.1 is manufactured in the in_liner Production Plant in Gdów in the Małopolskie voivodeship opened in June 2019. t is an innovative factory, the first plant in Poland in terms of size that manufactures ECR fiberglass liners for trenchless rehabilitation of pipes featuring record diameters in the Polish market i.e. up to DN2000. The in_liner 2.1 DN1800 19 mm thick liner was manufactured and successfully installed to rehabilitate the sewer system in Białystok in 2022. It is noteworthy that it is the record liner featuring so large diameter, first to be manufactured and installed in Poland.
