The towers were never about water
When the spheres rose over the bay in 1976, the engineers measured volume. The city measured something else entirely — a promise it could finally see from the road.
I spent three afternoons last spring on the access road below the main tower, watching the light move across its painted bands. The contractor's drawings call them "cladding zones." Everyone in the neighbourhood calls them the stripes, and the stripes are the point. A reservoir does not need to be blue and white. It needs to be sealed.
A reservoir that wanted to be a sign
The brief that crossed the planning desk in 1968 asked for storage capacity and reliable pressure. What got built, eight years later, also asked the harbour to read it as a headline. The ovoid head, tapering shaft, and daylight palette borrowed from oil-company signage were load-bearing in another sense.
"We were pouring concrete for a utility and casting a portrait of the decade at the same time."
That double duty is why the towers outlasted the optimism that built them. The reinforced bases sit in warm desert stucco; the heads catch the sky. It is a modernism that refused to apologise for being legible from a moving car.
