Lake to tap.

How a winter storm over the Sooke Hills ends up in a glass of water in Victoria.

Seven stops, one drop. Follow the water from the rain gauge to the kitchen tap, with the real numbers from the region's own reports.

Stop 01 · Rain

It starts as a Pacific storm

Wet winter systems roll in off the ocean and stall over the hills northwest of Victoria. Most of the rain arrives between fall and spring, and the reservoir has to carry the region through the dry summer.

Stop 02 · Watershed

A forest that works as a filter

The rain lands in a protected watershed of old forest, moss and creeks. Public access is restricted, and the Capital Regional District owns nearly all the land around it, so the water stays clean at the source.

That protection is the first barrier in a multi-barrier system.

Stop 03 · Sooke Lake Reservoir

The lake that holds the region's water

About 30 km northwest of downtown, Sooke Lake Reservoir has supplied Victoria since 1915. Its dam was rebuilt in 1970 and raised again in 2002–03 to store more of each winter's rain.

In 2024 it supplied all of the region's source water.

Stop 04 · Kapoor Tunnel

Straight through the mountain

Water leaves the lake through two 1,200 mm pipelines to a head tank, then enters the Kapoor Tunnel: a concrete-lined bore, finished in 1970, that runs through the rock to the Goldstream valley.

Stop 05 · Goldstream Water Treatment Plant

Light, then chlorine

At the plant in Japan Gulch, ultraviolet light disables microorganisms. Chlorine is added next, then ammonia, which forms chloramine to keep the water safe on its long trip through the pipes.

The water is not filtered. Its turbidity is low enough that the system qualifies for a filtration exemption from the province.

Stop 06 · Distribution

Under every street

Large transmission mains carry the treated water to storage reservoirs on high ground, like the one on Mount Tolmie, which hold supply ready for peaks and emergencies. From there, each municipality's network takes over.

Stop 07 · Your tap

Into the glass

A drop that may have fallen on the Sooke Hills months earlier comes out of a kitchen tap, tested along the way by thousands of samples a year.

Process

Directed by a designer, built with AI

I wanted to turn public infrastructure data into a story people would actually scroll through. I researched the system in the Capital Regional District's own reports, wrote the narrative as seven stops and set the art direction: one painterly opening image, then a calm series of technical models where water is the only colour, so the eye always follows the drop.

Magnific generated the opening paper-cut landscape from my prompts. The seven stops are schematic isometric figures built in code with Claude, each one a small real object that explains its step: a rain gauge, a contour model, a dam, a tunnel section, a treatment line, a city block and a kitchen tap. I chose every scene, checked every number against its source and finished the images in Adobe Creative Cloud.
