Sewer System Inspection
The technologies used by Can-Explore enable it to detect, quantify and qualify anomalies (signs of deterioration) in sewer systems. A detailed report provides an accurate picture of the system’s condition, including cracks, deformations, obstructions, etc.
With good knowledge of the sewer system’s working order, it is easier to plan repairs or replacements, therefore limiting emergency work and associated costs. Our inspections are PACP/MACP certified in accordance with recommendations of the Guide d’élaboration d’un plan d’intervention pour le renouvellement des conduites d’eau potable, d’égouts et des chaussées1 issued by the Ministère des Affaires municipales et de l’Occupation du territoire (MAMOT).Contact us
The camera equipment we use to inspect and diagnose sanitary and storm water systems includes:
- Pan and tilt camera (diameter > 100 mm);
- Zoom camera;
- Drain camera (diameter from 50 mm to 200 mm).
Our engineering team proposes the best solutions to meet the project’s needs. The number one objective in all Can-Explore’s projects is to effectively collect data, process it accurately and promptly deliver the inspection report.
In addition, Can-Explore inspects sewer systems after installation or repair work. These inspections are certified according to the Pipeline Assessment and Certification Program (PACP) and therefore comply with standards established by the Bureau de normalisation du Québec (BNQ).
- BNQ 1809-300
- BNQ 3680-125
All reports produced by Can-Explore after the inspection work meet recognized standards. These reports give an accurate picture of the operational and structural conditions of the sewer system and serve to make recommendations for corrective work. Can-Explore uses CTSpec to prepare its reports and meet all industry standards.Contact us
Ovality Testing on Pipes
Can-Explore conducts ovality tests to make sure pipes are not deformed. The gauges used are specifically designed for each pipe diameter and can measure maximum allowable deflections, i.e. 5% after construction and 7.5% after one year.
Can-Explore is also able to conduct deformation tests using a laser profiler to identify any irregularities along a pipe.Contact us
Detection of Cross-Connections
he smoke test helps detect non-compliant connections. Non-toxic smoke is introduced downstream in the sanitary sewer system. By checking where the smoke comes out, we can establish if components of the storm water sewer are inadvertently connected to the sanitary sewer system.
The dye test also serves to detect non-compliant connections, but works a different way. A dye is added to the water evacuated by one of the components suspected of being connected to the wrong system. Using a camera, it is possible to see where the water drains and therefore ensure that pipes are configured properly.Contact us
Pipe Flow Measurement
Can-Explore has all the necessary equipment and expertise for measuring the flow in sanitary or storm water sewer systems. The types of flowmeters used are:
- The height-velocity flowmeter measures water height along with flow velocity to give the pipe flow
- The height flowmeter only measures the height and a theoretical velocity is used depending on the type of material of the pipe, its diameter and slope.
Review of Plans and Localization of Pipes
Can-Explore can accurately reproduce a sewer system plan and determine the exact location of all its components. In addition to providing surveying services for accurately implementing various elements of the system, we can also provide the precise layout of pipes and incorporate it into a plan.Contact us
