Business Chief USA – August 2019

towards what we’re trying to achieve

as a sustainable desert city.”

A big part of that sustainability

journey is a series of major projects

including the 91st Avenue wastewater

biogas project (the largest facility of

its kind in the US). “Our water depart-

ment is capturing methane from our

wastewater, putting it in a pipeline and

generating revenue by selling it to the

California green energy market. It’s a

great example of finding a use for the

methane from wastewater treatment.

In addition to the biogas, we actually

reuse nearly all of the wastewater.

carbon, zero waste,

clean air, maintaining

our 100-year supply

of water, and parks

and transit in every

neighbourhood will

really drive us towards

what we’re trying to

achieve as a city”
