Every household in Metro Vancouver eventually faces this question: should you get bottled water delivered to your door, or install a home water filter? Both solve the same problem — getting better-tasting, cleaner water — but in very different ways. This guide breaks down the real costs, pros, and cons of each option so you can make an informed decision.
The Core Difference
Water delivery means a company brings pre-purified water to your home in 5-gallon jugs on a regular schedule. You store the jugs and use them as needed.
A home water filter — whether under-sink, countertop, or whole-home — filters your tap water in real time at the point of use. You pay upfront for the system, then ongoing costs for filter replacements.
Cost Comparison: Real Numbers for Metro Vancouver
| Cost Factor | Water Delivery | RO Filter (Under-Sink) | Countertop Filter |
|---|---|---|---|
| Upfront cost | $0 | $400–$800 installed | $60–$300 |
| Annual filter cost | $0 | $100–$200/yr | $50–$150/yr |
| Annual water cost (family of 4) | $312–$624/yr* | $0 | $0 |
| 5-year total cost | $1,560–$3,120 | $900–$1,800 | $310–$1,050 |
| Cost per litre | $0.34–$0.48 | $0.02–$0.05 | $0.08–$0.20 |
| Installation required | None | Plumber recommended | No |
| Maintenance required | None | Filter changes 1–2×/yr | Filter changes 2–4×/yr |
*Based on 2–4 jugs/month at TajWater subscription pricing ($6.49–$8.99/jug). Family of 4 typically uses 2–4 five-gallon jugs per month for drinking water.
On a strict per-litre basis, a reverse osmosis filter is significantly cheaper over 5 years. However, cost per litre is not the whole story.
Where Water Delivery Wins
Zero upfront cost
No installation, no equipment purchase. You start receiving premium water immediately with no capital outlay. For renters, this is often the only practical option — you cannot install an under-sink filter in a rented unit without landlord approval.
Multiple water types available
With delivery, you can choose spring, alkaline, or distilled water — and even get different types for different uses (e.g., distilled for your CPAP, spring for drinking). A single home filter produces one type of filtered water.
Distilled water for CPAP and medical use
No home filter produces truly distilled water. CPAP machines, baby formula, and medical equipment require distilled water — a need that only water delivery can meet from your home tap.
Portability and convenience
Stored 5-gallon jugs are available even during tap water disruptions (boil advisories, infrastructure failures). Metro Vancouver has experienced occasional boil advisories — your delivery water is unaffected.
No maintenance or filter changes
Water delivery requires no maintenance whatsoever. RO systems need filter changes every 6–12 months; if you forget, water quality degrades. Delivery water is consistent batch to batch.
Where Home Filters Win
Lower long-term cost per litre
If you drink a lot of water and plan to stay in your home for 3–5+ years, an RO system can cost significantly less per litre than delivery. The payback period for an installed RO system is typically 3–5 years compared to delivery costs.
Unlimited supply on demand
A filter produces water on demand — no waiting for a delivery, no running out between deliveries. You always have as much as you need directly from the tap.
Less plastic usage
Although TajWater reuses and sanitizes all jugs, home filters have no ongoing plastic waste at all. If reducing plastic is a priority, a filter has a smaller ongoing footprint.
Good for high-volume cooking
For households that use filtered water for cooking, soup stocks, pasta, and other high-volume uses, running a faucet filter is far more practical than cycling through 5-gallon jugs.
Which is Right for You? A Decision Guide
Choose Water Delivery if you...
Choose a Home Filter if you...
Many Metro Vancouver Households Do Both
A common setup is to have a countertop filter for high-volume uses (cooking, coffee, everyday tap drinking) and a water delivery subscription for premium drinking water, CPAP machines, or specific water types. This gives you the best of both worlds without the high cost of using delivered jugs for everything.
TajWater also offers water filter installation services for under-sink reverse osmosis and whole-home filtration — so whether you choose delivery, a filter, or both, we can help.
Bottom Line
Water delivery costs more per litre than a home filter, but it offers convenience, flexibility, multiple water types, zero upfront cost, and zero maintenance. It is the better choice for renters, households with specific water needs (CPAP, infants), and anyone who values simplicity over cost optimization.
A home filter is the better long-term value for homeowners with high water usage and no specialized needs — but only if you stay on top of filter maintenance.
