Your data

The site survey form asks only for what a survey needs and a way to reply. Its spam check is Cloudflare Turnstile, which looks at your browser to tell a person from a bot. There are no analytics, no advertising cookies and no tracking. The typefaces are served with the site, and the animation library loads from a public CDN.

The water

The water on the home page is a live simulation that runs on your graphics card. If you prefer reduced motion, or your browser has no WebGL, a still version takes its place.

This site

Designed and built by Neviox. Tarn, its plant and its pilots are a design study: the treatment stages, the drawing conventions and the instruments are real practice in water reuse, and the figures are not measurements.
