A new index for water quality at household scale.

A water-quality reading is useless to a household if it is not legible to one. We have built the Reserve Water Index — a single weekly number, derived from eleven parameters, that any member can read on the QR tag.

How the index is built

Each of the eleven parameters is normalised against published reserve-grade ranges. The composite is rescaled to a 0-100 index, weighted slightly towards dissolved oxygen and ammonia.

Why publish it

Because the household, not the regulator, is the customer of our standards. A reserve that publishes its weekly score is harder to lie to and easier to trust.

Key takeaways
  • Eleven parameters distilled to one weekly number.
  • A 0-100 scale; above 80 is reserve-grade.
  • Households read the score directly on the harvest QR tag.
