Methodology
Greater Victoria Drainage publishes two kinds of number and keeps them apart: figures quoted from the body that issues them, and estimates we calculate ourselves and label as ours. No page states a figure that is not one of those two.
One fact layer
Every figure is a record carrying its source, jurisdiction, effective date, the day a person last checked it, and how dangerous it would be to be wrong about it. Pages do not contain numbers; they contain references to those records, which is why the same figure is identical everywhere it appears, including in the phone and text assistants. The whole set is published at /api/facts.
What happens when a figure goes out of date
Each figure has a date by which it must be re-checked, and what happens after that date depends on what kind of figure it is. Programme amounts, eligibility rules and deadlines cannot be published at all once their check is overdue — the site fails to build rather than show you a stale one. Regulated limits and published prices are withheld and shown as “not currently verified”. Our own market estimates keep showing, flagged. Physical facts and definitions do not expire.
Right now the site holds 50 figures: 0 where being wrong costs money or a deadline, 39 regulated or published, 11 market observations and our own estimates, and 0 that do not expire.
The tools
Each tool is deterministic: the same answers always produce the same result, and every one of them publishes what it reads, how it calculates and what it is not, on its own page. None of them is a model guessing.
- Drain problem assessment — Your symptoms, your house and the weather, turned into the likely causes in order — and whether a camera is worth paying for yet.
- Scope, clean, repair or replace — Which of the four is the right next step for your house, what each one buys, and what it costs here.
- Compare drainage quotes — Two or three quotes in one table: where they differ on discharge, pipe, stone, camera and reinstatement — and whether the totals are comparable at all.
What the numbers are not
Code and municipal requirements are quoted from the sources above; price ranges are what named local companies publish, and the companies that publish them sell the work. Nothing here is a diagnosis of a particular house: only a camera in your own drain can tell you what is wrong with it.
