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.

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

Who approves septic work around Delta?

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.

Delta local-route status: The strongest verified regulatory anchor for this page is the British Columbia provincial/regional onsite-wastewater framework. The municipal website remains useful for sewer-service, zoning, building and property-record questions, but this guide does not label a generic city homepage as a septic permit authority unless the official material clearly says it is.

Delta: municipal sewer and septic record checks

Local municipal sewer information is used to check service availability, not to invent a separate municipal septic permit. Confirm servicing for the exact parcel. The health-authority filing route remains governed by the BC Sewerage System Regulation.

  • Delta publishes a sanitary sewer and drainage service page, including engineering contacts for questions about the City network. The existence of a nearby main or service line does not by itself prove a particular property is connected.
  • Delta Sanitary Sewer Use Regulation and Connection Charge Bylaw No. 5783 governs municipal sewer use and connection charges. This is distinct from provincial authorization for an onsite system.
  • If the parcel uses onsite wastewater disposal rather than the municipal system, Fraser Health and the BC Sewerage System Regulation govern the onsite filing and certification route. Confirm the parcel's system records first.

If sewage is backing up or surfacing, stop using affected fixtures and contact a qualified professional or the responsible authority. Never enter a septic tank.
