A sewer-line problem can look simple from a basement cleanout, but the buried pipe may run under a finished floor, driveway, lawn, easement or public road before reaching the municipal sewer. That route determines the approvals, safety controls and restoration involved. This guide answers the permit question for Ottawa homeowners without pretending that every address follows one identical process. It also explains when a camera inspection is useful, how repair and replacement differ, and what your contractor should document. For general plumbing emergencies, see our [Ottawa plumbing guide](gui...

A sewer lateral can include a private section on the lot and a connection toward the municipal system. Interior drain work, private excavation and work in the road allowance may have different requirements. The safe answer is to have a licensed plumbing or excavation professional identify the work limits, then confirm the City of Ottawa process before digging. A verbal “no permit needed” is not enough when the work changes the connection, affects a public right-of-way, or requires road, sidewalk...
The property owner is usually most directly involved with the private portion, but responsibility and maintenance obligations can vary with the service arrangement and location. Your contractor should mark the property line, easement, cleanouts and proposed excavation. If the line runs under a share...
A camera inspection can show roots, collapsed sections, offsets, grease, standing water and bellies. It cannot confirm the ownership boundary or authorize excavation. Request a video or still images with the distance counter, cleanout location and a written interpretation. That record is useful when...
Start with the City of Ottawa’s [building-permit information](https://ottawa.ca/en/planning-development-and-construction/building-permits) and confirm the address-specific rules with the contractor or permit office. Before excavation, submit an [Ontario One Call locate request](https://ontarioonecall.ca/) and arrange private locates where the public service does not cover homeowner-owned lines. Ask who obtains any road-occupancy, sidewalk or traffic-control approval.
Collect the camera report, a site sketch, photos of cleanouts and basement symptoms, any prior sewer invoices, a survey or easement information if available, and the age of the home. Homes in older Ottawa neighbourhoods may contain clay, cast-iron or vitrified-clay sections, while newer subdivisions...
Ask whether the work is a repair, replacement, new connection, disconnection or alteration; whether plumbing, building, road or environmental approvals apply; which inspection occurs before backfill; whether a municipal representative must observe a connection; and how the contractor will respond if...
A spot repair can make sense when a short section has failed and the rest of the line is sound and accessible. Full replacement is more likely when the pipe has repeated breaks, severe root intrusion, a collapse, poor grade, multiple offsets or a long deteriorated run. Trenchless methods may reduce surface disturbance but are not suitable for every alignment, diameter, access condition or structural problem. A trustworthy recommendation explains why a method fits the evidence.
Request a camera-only or diagnostic scope, a targeted repair scope and a full replacement or trenchless scope when each is technically feasible. Compare the length, depth, pipe material, cleanouts, access, permits, testing, backfill and restoration. Do not compare one quote that includes a finished ...
Repeated backups, sewage odours, slow drainage across several fixtures, wet or sunken ground, a new depression over the line, and sewage surfacing outdoors deserve prompt professional assessment. Avoid chemical drain cleaners as a substitute for diagnosis. Keep children and pets away from contaminat...
Sewer excavation is not just a digging job. The crew must protect the trench, locate utilities, control groundwater, keep excavated soil away from the edge, and provide safe access. Never enter an unsupported excavation. The contractor should explain how the house will remain connected or temporarily protected, how open pipe ends will be capped overnight, and how rain or spring melt will be managed.
A private sewer can pass below mature roots, decks, asphalt, concrete, gardens or an addition. Ask whether the proposal includes removal and replacement of each surface, not just “backfill.” Ottawa frost and spring settlement make compaction and final grading important. If a temporary repair is made...
Confirm shoring, fencing, lighting, dust control and dewatering. Keep a photo record before demolition. If a foundation wall or slab is opened, the scope should state how it will be sealed against water and radon pathways where relevant, and how concrete, insulation and finishes will be restored.
Do not let the crew backfill until the required inspection has happened. Photograph the new pipe, joints, cleanouts, bedding, sleeves and crossings. Keep the permit, inspection result, camera video, invoices, product information and restoration warranty. Ask for an as-built sketch showing the route from the cleanout to the municipal direction. Future owners and future contractors will benefit from that record.
The written proposal should identify the diagnosis, method, excavation limits, pipe material and size, permits, locates, inspections, temporary protection, disposal, groundwater, backfill, compaction, testing, basement restoration and surface restoration. It should also explain change orders. Our [g...
Verify insurance, experience with sewer laterals and references for similar access conditions. Ask who will actually perform the plumbing connection and who is responsible for excavation safety. A very low quote that excludes permits, inspection or restoration is not a fair comparison. Use our [Otta...
The requirement depends on the exact work and location. Private excavation, a connection alteration and work in a public right-of-way can follow different approval paths. Confirm the scope with the City and have the contractor identify the inspection before backfill.
Yes, utility locates are important even on private property. Public locates may not identify every privately owned service, so ask whether a private locate is also needed.
Usually, because it can show the location and type of failure before excavation. Request the recording and a written interpretation, and remember that the camera does not replace a permit or locate.
Sometimes. Spot repair or trenchless options may reduce surface disturbance, but suitability depends on access, alignment, pipe condition, grade and the type of failure.
