Tour: How Hassalo on 8th Saved Money by Reusing Water

Meet: Near the elevators in the plaza of Hassalo on Eighth (1061 NE 9th Ave Portland OR 97232)

When: June 9th 2017 12:30-2pm

Presenters: Pete Muñoz of Biohabitats and Tom Puttman of Puttman Infrastructure

Portland’s latest paradigm shift development, Hassalo on Eighth, proves that a market driven development can achieve some of the highest water reuse standards in the nation.

This new development in Portland’s Lloyd District doesn’t flush to the sewer system, instead three new buildings treat all their wastewater on-site (60,000 gallons perday) and reuse it to flush toilets, cool mechanical systems and water plants in a central plaza.  This is the first project in the state of Oregon to allow a project served by a sewer system to do it all themselves on site, and may demonstrate that recycling wastewater can make financial sense for both the city and developers.

The project showcases the economic and ecological benefits of district scale onsite wastewater treatment and reuse. The new buildings add 657 apartments, 1,200 parking stalls, an outdoor plaza, and bike parking for 900 bicycles to the district. The project is LEED Platinum and its unique features has helped draw people to live in the Lloyd District.

In this presentation participants will be able to:

  • Understand building wastewater recycling systems and costs.
  • Identify developer risks and benefits of adding onsite wastewater recycling systems.
  • Learn about incentives and how to successfully negotiate designs with code and utility regulations.
  • Understand operations and maintenance concerns for post occupancy as well as regulatory water testing and reporting requirements.
  • Understand how the project’s water strategies reduce energy use


Organizer: Cascadia Green Building Council’s Portland Collaborative and Recode.

Cascadia Green Building Council’s Portland Collaborative is the pre-eminent forum for sustainable development advocacy in and around the Portland Metro Area.

Recode is a nonprofit working to ensure access to and accelerate adoption of sustainable building and development practices.  Recode is currently focused on performance based approaches to governance that will accelerate the use of innovative water and sanitation systems that are more efficient, affordable, and sustainable. Specifically, Recode seeks to break down both legal barriers (especially outdated codes) and informational barriers (such as outdated assumptions about feasibility) and inspire policies and systematic approaches that allow the use of affordable, eco-friendly, regenerative water and sanitation systems in new and remodeled commercial and residential buildings. Recode led the coalition that successfully legalized graywater reuse in Oregon and widened the legal options for composting toilets.
