Surface material: paving
Concerns regarding pH: Groundwater table located approximately 4.8 m above the main pipeline
The Context
Major upgrade of the sewer and water system in an urban area
The City of Joliette has undertaken a vast project to upgrade its sewer and water systems in an urbanized area with several physical and technical constraints.
This second phase aimed to replace a segment of the stormwater drainage system, while maintaining traffic, access to surrounding buildings, and active municipal services.
The main objective: to integrate a durable, waterproof solution that is perfectly suited to complex construction site conditions, including unstable clay soil and a large burial depth.
The Challenges
Deep installation with tight spaces required large HDPE pipe
The project involved a deep pipe installation of up to 4 meters, requiring a 2,400 mm diameter large HDPE pipe as the main conduit. Construction took place in a densely populated urban area, surrounded by schools and commercial buildings, leaving minimal room for staging and maneuvering.
The unstable clay soil conditions further complicated excavation and backfilling, demanding a solution that could adapt to poor ground stability. Adding to the complexity, the work had to be carried out while maintaining full operation of active municipal services, including the aqueduct and sanitary sewer lines.
Additionally, a secondary network located above the main system required careful coordination to ensure both networks remained functional throughout construction.
The Solution
KUSTOMFLO HDPE pipes, custom-made.
The city opted for KUSTOMFLO large HDPE pipes, custom-made with KRAH technology. This solution offered precise customization, making it possible to meet diameter, strength and assembly requirements under extreme conditions.
Soleno also provided custom-made manholes, designed in a virtually monolithic manner to simplify their installation at the desired height.
“What I like most about the KUSTOMFLO product is how easy it is to handle. It’s a huge advantage in conditions like the ones we had here. –

The Benefits of KUSTOMFLO large HDPE pipe
"The manholes are as easy to install as a standard hose, and above all, very light."
A solution for the future for cities in transition. This project demonstrates how KUSTOMFLO pipes are a sustainable, adaptable and cost-effective solution for municipalities, combining structural performance, ease of installation and environmental resilience.
Accelerated installation despite depth and soil conditions, thanks to the lightness and maneuverability of HDPE pipes.
Maintaining access to surrounding buildings throughout the project.
Reduced handling and safety risks on site.
Flexibility of adjustment during the project, thanks to the responsiveness of the Soleno technical team.
Avoidance of delays: Soleno quickly presents itself on site to adapt certain elements and ensure the continuity of the work.
Excellent urban integration at the end of the project with the complete redevelopment of the street: bike paths, sidewalks, tree planting.
