OpenStats picks for Surrey — everyday tap water
Surrey's 22 mg/L supply is relatively soft — filtration is mostly about chlorine taste. A certified pitcher or compact under-sink unit is enough for most homes.

Supply and treatment
How Surrey draws, treats, and distributes drinking water, from municipal and utility publications. Chemistry grades above come from separate parameter records; this section does not invent plant lab figures.
Source type
Surface water
Research confidence: high
Source waters
- Capilano Reservoir
- Seymour Reservoir
- Coquitlam Reservoir
Treatment plants
Seymour Capilano Filtration Plant
Regional Metro Vancouver treatment for Capilano/Seymour sources.
Coquitlam Water Treatment Plant
Regional Metro Vancouver treatment for Coquitlam source; Surrey reports receiving a large share of supply via Coquitlam and Seymour crossings (Annacis, Port Mann, Barnston).
Distribution
Surrey buys all potable water from the Greater Vancouver Water District and operates one of BC’s longest municipal distribution networks, with many pressure zones and pump stations. Secondary chlorination is applied before water enters city mains; no further municipal treatment.
Health parameters meet Health Canada limits; turbidity above the 1 NTU typical target.
Health parameters meet Health Canada limits; turbidity exceeds the typical 1 NTU aesthetic target.
