context
Major upgrade of the storm and sanitary sewer system in a dense urban area.
The City of Joliette undertook a large-scale upgrade of its storm and sanitary sewer networks in a built-up sector with several physical and technical constraints.
This second phase aimed to replace a section of the stormwater drainage network, all while maintaining traffic flow, access to surrounding buildings, and uninterrupted operation of active municipal services.
The main objective: to integrate a durable, watertight solution that could be perfectly adapted to the complex site conditions, including unstable clay soils and deep burial depth.
First Phase
The Challenges
Deep installation in confined urban conditions
- Deep excavation requirements: Installation at depths of up to 4 meters, involving a 2400 mm diameter main pipe.
- Demanding soil conditions: Unstable clay soil complicated both excavation and backfilling operations.
- Space limitations: The work zone was in a densely built urban area, with schools and commercial buildings in close proximity.
- Active municipal services had to remain fully operational throughout the construction (water supply and sanitary sewer).
- Dual network configuration: A secondary network was located above the main pipe alignment.
The Solution
Custom-manufactured KUSTOMFLO HDPE pipes
The city selected KUSTOMFLO HDPE pipes, custom-manufactured using KRAH technology. This solution offered precise customization capabilities—diameter, wall thickness, stiffness—to meet the specific needs of the site under extreme conditions.
Soleno also supplied custom-made manholes, designed to be nearly monolithic, making them easy to install at the desired elevations.

The Benefits
« The manholes are as easy to install as standard pipes—and most importantly, they’re very lightweight.. »
A forward-looking solution for cities in transition
This project illustrates how KUSTOMFLO pipes offer a sustainable, adaptable, and cost-effective solution for municipalities, combining structural performance with ease of installation and environmental resilience.
- Accelerated installation, despite challenging soil and depth, thanks to the lightweight and manoeuvrability of HDPE.
- Maintained access to surrounding buildings throughout the duration of the work.
- Reduced handling and on-site safety risks.
- Flexibility to adapt mid-project, supported by Soleno’s responsive technical team.
- No downtime: Soleno’s fast on-site response enabled real-time adjustments to keep the project moving forward.
- Strong urban integration at project completion, with full-street revitalization: new bike lanes, sidewalks, and tree planting.
