Port of Portland operations depend on waterways, so we must do our part to not only protect water quality, but also to reduce water usage to help conserve this natural resource.
In addition to landscaping that requires less frequent watering, we installed water delivery lines that use nonpotable water for irrigation purposes. We irrigate using drip systems versus spray irrigation, which reduced water use by up to 57 percent at one site. And at two of our industrial parks, we installed irrigation control systems that use real-time weather data to determine if watering is needed on a given day. This last effort has reduced water usage for irrigation by 30 percent.
Regular audits help keep us on track, and we continually look for ways in which we can further reduce water usage in our landscaping departments.
