Water savings calculator

How much is that leak costing you? Work out the annual cost of a continuous water leak at your own water and sewer rate, in Canadian dollars.

This section will contain

  • Inputs (§G.1): leak rate (LPM) · hours/day · days/year · water + sewer rate ($/m³).
  • UX: simple first (2–3 inputs → estimate), then an optional Refine step.
  • The result is a data-viz moment, not form output: a §E widget with the money figure large and tabular.
  • Export as CSV. The on-page result stays free and crawlable — and it is the ONLY thing this deployment delivers: §G.1's emailed PDF report is not built, so nothing on this site offers one. [TOM-REVIEW] §K.2.

What a leak costs

A leak is the easiest number on this page to check: you already know your water and sewer rate, and a leak runs whether or not the plant does.
