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.

Open health authority onsite-wastewater page →

Onsite system confirmed

Find the parcel’s system approvals and verify current rules with the responsible local authority before work.

Start with provincial guidance →

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. Open provincial / regional onsite-wastewater authority →
Two approvals can be involved. City sewer-service rules and records tell you whether a municipal connection is required or available; provincial/health-authority rules govern any lawful onsite system. Check the actual address with the appropriate authority before excavation, alteration or purchase.

Who approves septic work around Langley?

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.

Verified local route: The named municipal source above supplies a distinct service, sewer mapping or property-record step. It does not independently verify whether an individual parcel uses sewer or septic.

City-specific service and records route — City of Langley — not Township of Langley

This page describes the CITY OF LANGLEY only. City Sanitary Sewer and Storm Sewer Regulation Bylaw No. 3210, section 4.2, states that septic tanks/systems are not permitted in the City. Sections 4.3 and 4.10 govern approvals and sewer connections, including City Engineer inspection steps. Before assuming the property is in Langley City, confirm its municipal boundary: the separate Township of Langley has different land-use and servicing requirements. This bylaw is not a blanket septic prohibition in the Township.
