Vancouver RaincatchersIs It Illegal to Collect Rainwater in Vancouver?
No — and with Stage 3 watering restrictions now in effect across Metro Vancouver, a rainwater harvesting system is the single best way to keep your garden legally watered all summer.
The Short Answer
Collecting rainwater is completely legal in Vancouver and all of British Columbia. The City of Vancouver actually requires on-site rainwater management for most new buildings. Metro Vancouver's watering restrictions apply only to treated municipal drinking water — not to rainwater you capture from your own roof.

FAQ
Common Questions About Rainwater Legality
Is it illegal to collect rainwater in Vancouver, BC?
No. Collecting rainwater is completely legal in Vancouver and across British Columbia. In fact, the City of Vancouver requires on-site rainwater management for most new buildings, and the Vancouver Building By-law includes specific provisions for non-potable water systems under Section 2.7.
Do Metro Vancouver water restrictions apply to rainwater I've collected?
No. Metro Vancouver's watering restrictions apply only to treated drinking water supplied by the municipality. Water you collect from your own roof in a rain barrel or cistern is your property and is exempt from all watering restrictions, including Stage 2 and Stage 3 bans.
What are Metro Vancouver's Stage 3 water restrictions?
Starting June 8, 2026, Metro Vancouver is in Stage 3 restrictions. Lawn watering remains banned. Trees, shrubs, and flower gardens may only be watered by hand or with drip irrigation. Sprinklers, sprinkler systems, and soaker hoses are prohibited for all properties.
Can I use collected rainwater on my garden during a watering ban?
Yes. Because rainwater harvesting systems capture water that has not been treated by Metro Vancouver, the resulting supply is not subject to municipal watering restrictions. You may legally water your lawn, garden, trees, and shrubs with harvested rainwater at any stage of restriction.
Are there building code requirements for rainwater systems in Vancouver?
Yes. The Vancouver Building By-law 2019 adopts the BC Building Code, which includes Section 2.7 governing non-potable water systems. A key requirement is that non-potable systems must never be physically connected to the potable (drinking) water supply. Professional installers ensure all work meets these code requirements.
Can I drink the rainwater I collect?
Rainwater collected for drinking requires treatment and filtration to meet BC's drinking water standards. The BC Ministry of Health publishes guidance on treating harvested rainwater for potable use. Most residential systems we install are for irrigation only, which requires no treatment and carries no drinking-water regulations.
Will a rainwater tank increase my property value?
Yes. With recurring summer droughts and tightening water restrictions, homes with established rainwater harvesting systems are increasingly attractive to buyers. A system signals lower water bills, garden resilience, and compliance independence — all valuable in Metro Vancouver's climate.
