Emergency Sewer Repair

Provide the site address, sewer type, affected buildings or operations, first observed time, visible flooding or settlement, maintenance-hole locations, known pipe size and material, and any CCTV or drawings. Tell us about access limits, production discharges, confined areas, traffic, and whether municipal staff or environmental authorities have been notified.

Yes, when incoming flow can be safely intercepted and conveyed to an authorized downstream point. We size and arrange bypass pumping around the sewer type, expected peak flow, downstream capacity, crossings, and consequence of interruption. Some facilities also reduce or schedule discharge while the permanent pipe repair is completed.

We combine maintenance-hole inspection, cleaning response, CCTV distance, surface measurement, pipe alignment, invert information, and available drawings. If a camera cannot pass the defect, observations from the opposite direction can narrow the station. Utility locates and controlled daylighting then verify nearby infrastructure before the main excavation proceeds.

Open cut is preferred when the pipe has collapsed, line and grade have shifted, the surrounding soil has washed out, a connection or structure has failed, or the host pipe cannot support a liner. Trenchless repair suits defects that remain accessible and have enough structural and geometric integrity for the specified system.

The owner’s incident procedure identifies reporting authority, while the party with control of a pollutant has duties under Ontario law. Harrowgate contains the release, protects drains and watercourses, separates affected liquids and material, supports cleanup and disposal, and documents field actions. Reportable events are communicated promptly to the municipality and MECP as required.

We verify pipe material, diameter, slope, invert continuity, joint engagement, coupling position, service connections, bedding, haunch support, and interfaces with structures. The specified leakage, deflection, CCTV, survey, or municipal inspection follows where applicable. Only accepted concealed work is covered, then embedment is placed evenly to avoid moving the pipe.

Settlement follows when saturated spoil is reused, soft trench bottom remains, bedding is not worked beneath pipe haunches, backfill lifts are too thick, or compaction cannot reach beside structures and services. We correct the foundation, use approved materials, control lift thickness and moisture, and complete density testing when the restoration specification requires it.

Yes. We phase barriers, traffic control, equipment access, bypass lines, excavation, and surface restoration around the required truck, pedestrian, and emergency routes. Work in a public right of way also requires the applicable road authority coordination. The repair plan identifies closures and operational windows before disruptive work begins.
