Gallery: Wastewater Treatment Plant In San Francisco Is a Gorgeous Indo...


When you think of a wastewater treatment plant, you probable picture a vast, unsightly pool surrounded by a concrete facility. You probably do not picture a serene wetland in the lobby of an office building, but that’s exactly how sewage will be treated in the new building of the San Francisco Public Utilities Commission. Design by Worrell Water Technologies, the constructed wetland, called Living Machine, will clean the building’s wastewater to make it suitable for reused in toilets, irrigation, and maintenance.

    These images are all different projects in Worrell Water Technologies’ portfolio and I believe none are actually the SFPUC building.

    I don’t really understand former comments. How do you know this garden doens’t work technically? It’s an idea that has been developed for half a century. Even living machine has practiced for 10 years already. Constructed wetland has been involved in industrial scale waste water treatment plant already. Here, living machine tried to present a different idea, treating waste water locally in a more natural way. It’s a LOCAL water solution reducing the stress on city infrastructure. That’s what LEED aims for. Membrane bio-readors or thermal de-polymerization are available only in industrial scale. It’s different concept. Also, it’s actually an energy solution, not for water.

    This is just a gimmick with no technical (scientific), environmental or economical benefit. The vegetation would look beautiful, no doubt. But if that’s what you are after why not just plant them without running the risk of exposing the public to sewage! There are other methods for treating sewage on a small scale that are far more efficient and economical.

    Real Utilities have to deal with hundreds of billions of gallons a year, pardon the pun but these devices are just a drop in the bucket. I agree it’s interesting if applied to every commercial building in the city. But this is more aesthetically pleasing than it is useful.

    Other devices like membrane bio-reactors and thermal de-polymerization offer useful industrial scale applications to deal with wastewater.
