{"id":"drainage-permits-greater-victoria","title":"Perimeter drainage permits and inspections in the thirteen Greater Victoria municipalities","description":"For all thirteen Greater Victoria local governments: whether the municipality publishes anything specific to perimeter drainage, whether the drain is inspected before the trench is backfilled, what needs a permit, and who may connect to the municipal system. Read from each municipality's own page, form or bylaw. Three of the thirteen inspect before backfill — that is the column worth having, and no municipality publishes it as a comparison because each states only its own answer. Where a municipality publishes nothing drainage-specific the cell says so; that is a finding, not a missing value.","publisher":"Greater Victoria Drainage","url":"https://greatervictoriadrainage.com/data/drainage-permits-greater-victoria","license":"CC BY 4.0 — reuse with attribution to Greater Victoria Drainage and a link to /perimeter-drain-permit-victoria","verified":"2026-09-22","recheck_by":"2027-03-22","sources":["victoria-inspections","victoria-plumbing","victoria-opendata-storm","saanich-plumbing","saanich-stormwater","oakbay-plumbing","northsaanich-bylaw1150","centralsaanich-permits","viewroyal-drainage","highlands-inspections","sooke-permits","metchosin-plumbing","esquimalt-plumbing","sidney-permits","colwood-permits","langford-permits"],"columns":["municipality","publishes_drainage_rules","inspected_before_backfill","permit_rule","connection_to_municipal_system","what_is_true_only_here"],"rows":[{"municipality":"the City of Victoria","publishes_drainage_rules":"specific","inspected_before_backfill":"yes","permit_rule":"Perimeter drain tile and dampproofing must be inspected before the installation is concealed and before backfilling","connection_to_municipal_system":"A plumbing permit is required to install or alter a connection to the stormwater utility.","what_is_true_only_here":"Victoria is one of only three municipalities in the region that will not let the drain be buried before someone has looked at it, and it is the only one that publishes where your storm lateral runs."},{"municipality":"the District of Saanich","publishes_drainage_rules":"specific","inspected_before_backfill":"not published","permit_rule":"Anyone may install perimeter foundation drainage, but storm laterals, sanitary sewer lines, rainwater leader systems and water lines may only be done by a certified plumber, a supervised indentured apprentice, or the registered owner-occupant with approved drawings","connection_to_municipal_system":"The storm lateral, the sanitary line, rainwater leader systems and water lines are restricted;
