First, confirm this property’s wastewater service

A city-area guide cannot tell whether a specific parcel is connected to sewer or has an onsite system.

Health authority / onsite records route

Use the health authority route below for onsite-system guidance, filings or records. Confirm sewer connection separately with the municipality or utility.

Service unknown

Check utility bills and permit records; ask the local authority to confirm current service before planning an onsite inspection or repair.

How to confirm service →
Provincial rule: British Columbia’s Sewerage System Regulation requires an authorized person to plan, construct or supervise most onsite sewerage-system work covered by the regulation, with filings made to the health authority before construction and certification after completion.

Coquitlam: verified service and approval steps (October 2026)

QtheMap has address search and sanitary utility layers with links to as-built records. The City also directs owners to Engineering and Public Works for sanitary, storm or water service records at the property line; these do not establish the building’s actual connection or onsite permission.

Next step: Check the city map and request property-line sewer records through Coquitlam Engineering and Public Works; for an onsite system ask Fraser Health for any filing/certification and consult an Authorized Person.

Verification boundary: Mapped sanitary lines and available as-builts are not an onsite approval. This page provides a defensible local research route, not approval of an individual system.

Who approves septic work around Coquitlam?

British Columbia’s Sewerage System Regulation uses an Authorized Person model. For typical residential systems, an Authorized Person files the required system information with the regional health authority and later files certification after construction.

For records, ask for the filing/record of sewerage system, site plan or as-built information, and any letter/certification on file. The municipality may control building or zoning issues, but the regional health authority is the key onsite-sewerage records route.
