Our three-year collaboration with the International Living Future Institute will develop solutions pathways that enable early adopters and practitioners to better navigate the range of cultural, financial, and legal challenges to adoption of sustainable wastewater treatment systems.  Solutions will be for Washington, Oregon and California; however during the first year, we investigated barriers and solutions from across the country. These could be at any scale of development, from single family residential to district scale.

Ultimately, our solutions will be created by working directly with jurisdictions and pilot projects that showcase sustainable wastewater treatment systems or by confronting barriers unclear or blocked by legal barriers. We recognize that widespread adoption of water reuse and decentralized sewage will only occur as a partnership with permitting agents and policymakers and that our collective knowledge will enable this progress for everyone.

This page highlights our work products and some of our successes to date.

Water Summit of the Living Future 2017 unConference

Many people are seated at round tables as Paula Kehoe addresses the room.

Recode sponsored Paul Kehoe of the San Francisco Public Utilities Commission to address the 2017 Water Summit participants regarding the groundbreaking water reuse work she and other partners are doing in California and nationally. A few months after the conference, Seattle adopted a rainwater harvesting regulation based on San Francisco’s water reuse code.

The International Living Future Institute and Recode teamed up to host the 2017 Water Summit one day before the start of the Living Future 2017 unConference. Over 80 attendees provided feedback on next generation water barriers and potential solutions pathways the informed our white paper above.

If you are looking for precedents of innovative approaches to next generation water and wastewater infrastructure check out the Code Innovations Database. Recode, Molly Winter, has contributed several case studies including one on a composting toilet pilot project in Cape Cod and a more successful one in Arizona.

Ever wondered about ATAC? They’re the all volunteer committee that has helped projects seek appeals for innovative green building practices from the high tech, like an air admittance valve to the low tech, like light straw clay. Come learn what ATAC does to help innovative projects get permits. This is part of a monthly series by the Portland Collaborative.

Join Molly in a facilitated discussion with Terry Whitehill of Portland’s Bureau of Development Services about ATAC.

When:   Wednesday, October 27, 5:30-7:30pm
Where:  Brightworks Sustainability, 412 NW Couch St #202, Portland, OR 97209

This is part of a monthly series the Portland Collaborative puts on to have fun network, and learn about green building initiatives, policies and techniques being deployed locally. The Portland Collaborative is a branch of both the Cascadia Green Building Council and the International Living Future Institute (ILFI).

The Alternative Technology Advisory Committee, authorized under Portland City Code 24.10.087, assists the Bureau of Development Services in reviewing innovate sustainable building technologies and methods for compliance with the Building Code requirements. The Committee reviews requests submitted by applicants to determine if emerging technologies can be found to meet the building code, as well as promote a positive impact to the earth’s natural systems. The Committee makes non-binding recommendations to the Director (or designee) of the Bureau of Development Services that can be considered as part of a building code appeal.

The town of Falmouth, Massachusetts near Cape Cod, authorized funding for a pilot project to evaluate the efficacy, installation cost and public acceptance of both composting and urine-diverting toilets (called the Eco-toilet Demonstration Program). Check out Recode’s case study in the Code Innovations Database.

Homeowners were given rebates and other incentives to encourage them to use eco-toilets.  Massachusetts is the first state to give a variance to allow urine-diverting fixtures and site-built composting toilets, which do not have ‘product acceptance’ in Massachusetts.

Arizona recently completed a two-year pilot project of 24 site-built composting toilets. Check out Recode’s case study in the Code Innovations Database.

 

This will help us know when and where to have more graywater workshops.

Intro to Policy Level Activism was held in October 2014. Our 2016 training focused on key stakeholders in regulatory agencies effected by composting toilets.

Thank you to the amazing participants of our October 2014 training where we introduced our methods and strategies. Thanks also to Kari Koch of Rise Communications for her sessions on Community Organizing and Facilitation/Presentation Skills.

The 2014 training covered:

  • Recode’s approach and strategies for effectively changing codes.
  • Performance based codes (an introduction, their benefits and implications).
  • How to give presentations on performance based codes. Don’t know what performance based codes are? That’s okay! You will after the training!
  • Honing your facilitation skills: Difficult people, difficult questions and holding space for truth.
  • The Mechanics of Successful Community Organizing with Kari Koch of Rise Communications. It’s more than just fliers and Facebook. Learn how to organize low stress, high impact events with up front strategizing, turn out mechanisms, and outreach planning for groups.

Since 2011 Recode has researched how other jurisdictions are creating codes that protect water resources while allowing for innovative solutions to our sanitation problem. Performance-based codes require that any sanitation system reduces pollution to an acceptable amount before the product of the sanitation system interacts with the environment. Current prescriptive codes don’t address a sanitation systems ability to protect the environment from pollution.

This training was specifically designed to increase the effectiveness of our current campaign to legalize all sustainable sanitation strategies in Oregon, but the approach can be applied to a range of strategic code changes (bees, fruit trees, zoning). We asked that attendees commit to giving one or more presentations in their local communities about the benefits of performance based codes.

Septic Demystified

How might our systems of governance be designed for learning — for both innovation and impact? In planning and development, one promising approach is called performance based: the use of regulations and codes that define desired outcomes, but not how such outcomes might be achieved.

Performance Standards in Onsite Sanitation Codes:

Performance codes start with setting a baseline reference for a pollutant outside the context of any specific technological solution, defining what needs to happen such that those pollutants are transformed into something acceptable for release into the environment, creating general guidelines for designing systems to make this happen, verifying that pollution is removed in the real world, and releasing performance data to the public.

Pollution Standard:
Pollution is defined as “daily loadings” that an average person will put on a sanitation system through their excrement and washwater, defining quantities of feces, urine, and other sanitation concerns that a typical household generates, as well as concentrations of pollutants such as nitrogen and phosphorus.

Performance Standard:
Performance is defined by logarithmic reductions of diseases and percent reductions in the discharge of nitrogen, phosphorus, and other concentrated pollutants in comparison to the baseline pollution standard with no treatment.

Design Standard:
All new systems could be designed for testability. For septic systems this means accessible ports in the tank and testing wells in the leach field or sand filter. In the event of an environmental concern, all systems can be tested if needed.

Verification System:
There’s a number of different ways to verify performance of different technologies, using existing standards, state test site results, etc.

Accessible System Data:
The testing and verification methodology is openly available, as is all testing data as well as average installed costs. This data assists homeowners in making choices, and policy makers in decisions.

Performance Based Codes in Sweden and Finland

The five points above are summarized from the codes in Finland and Sweden. Both countries passed legislation modeled after the USA’s Clean Water Act in the 1970′s, and created EPA departments modeled on the US EPA.

The Finnish rules are the Government Decree on Treating Domestic Wastewater in Areas Outside Sewer Networks (542/2003) [english]. The Swedish guidelines are Swedish EPA NFS 2006:7 [Swedish with English summary].

Performance Based Codes in the US

The National Onsite Wastewater Recycling Association has created a model code process supported by the US EPA. NOWRA’s model code provides excellent guidance on implementing Design Standards and a Verification regime.

Maryland has implemented a Verification system and testing standards independent of NOWRA but similar in its aims.

Goal

Our goal was to educate communities & regulators in Oregon about the benefits of creating “waste” treatment rules for Oregon that judge alternatives to septic and sewer systems on their performance and let alternatives compete on cost.  Our goal was to lay the groundwork for a positive, effective, apolitical sanitation rules process.

Achieved

We involved and educated over 200 citizens in our public presentations on ecological sanitation. Our largest presentation was to over 100 people at City Repair’s annual Village Building Convergence in Portland. Recode hosted public presentations & discussions with Department of Environmental Quality staff in Bend, Medford, Coquille, Ashland, Hood River, Pendleton, Portland, Eugene, Salem, and Gresham.

Recode discussion in Coquille, Oregon.

Recode’s Goal: legalize graywater re-use internally and externally for both owner-built and professional systems across the state.

Achieved: Recode led the coalition that successfully legalized external graywater re-use year round within greenhouses and seasonally for outdoor plants. Recode also collaborated early on with the team that legalized internal graywater reuse (for flushing toilets and cooling mechanical systems).

Recode organized the first public forum on graywater reuse in April 2008, co-sponsored by the Office of Sustainable Development. We invited collaborators including architects, builders, and advocates from the Portland community to discuss their desire for gray water reuse and their values around water.

From that forum two groups mobilized, one that focused on graywater reuse for internal use for flushing toilets (after treatment) and one that focused on external reuse for taking advantage of graywater for fertigating orchards and plants. A small group, including then co-chair of the Oregon State Plumbing Board Jon Gray advocated to create an Oregon Alternate Method to allow for interior use of rainwater and interior reuse of graywater within the plumbing code. The second group formed a legislative team on external graywater reuse co-charied by Recode founder Brenna Bell.

  • Brenna Bell and other Recode volunteers helped draft House Bill 2080
  • Met with key legislators including Jackie Dingfelder and Ben Cannon to gather support for the bill,
  • Attended every legislative session and hearing on the bill, and
  • Organized over 60 organizations to support the bill.
  • In order to keep the process science based and keep people informed of the process Bell provided regular updates to organizations and individuals about the bill.
  • In 2009 the Governor invited Recode to the signing of the HB2080 into law.

 

HB2080 legalized the reuse or graywater for external use, but specific codes needed to be created to outline how graywater reuse would be permitted and overseen by Department of Environmental Quality(DEQ) which oversees where water goes once it leaves bulidings. Bell was appointed to the Graywater Advisory Committee which worked with the DEQ to create the graywater rules. Recode volunteers Melora Golden and David Osborn created educational materials for that committee during the decision making process. Recode organized people to provide public comment at every meeting of the Advisory Committee and provide comment on the draft graywater rules.

To Do

Legalize disposal of graywater within “graywater reuse and disposal systems.”  The DEQ has chosen to interpret “reuse and disposal system” as a system with a valve to switch between reuse and disposal.  These goals have been incorporated into the Ecological Sanitation Campaign.

Background

In Oregon graywater for internal reuse was legalized in 2008 led by Jon Gray and other. Graywater external reuse was set in motion with HB 2080 in 2008 and the DEQ began accepting graywater reuse permits in April 2012. Check out  DEQ’s webpage on how to get a permitted graywater system for everything you need to know about the permitting process and recommendations for construction.

Tier 1 permit costs $50 for application fee + $40 annual compliance fee –fee waived if you renew online).

Includes <300 gallons per day of graywater used for

•Subsurface (2″) irrigation of gardens, lawns, and landscape plants, green roofs, compost, food crops (except root crops or crops that have edible portions that contact graywater)
• Subsurface (2″) drip into soil, mulch or compost
• Graywater must be used within 24 hours
• Graywater must not surface, pond, or runoff.

*Graywater can be used year round in a greenhouse.

Application for Tier 1 permit.

Tier 2 costs $534 for new application fee + $50 annual fee. Tier 2 is for systems expecting less than 1,200 gallons per day and graywater can be used for drip irrigation, ponds, or year round subsurface irrigation for a greenhouse.

Tier 3 permit fees depend on the project and are designed for over 1,200 gallons per day or reusing graywater for sprinklers or dust control. They’re expected to range from $545 – $2,723 for new application fee. Annual fees may range from $341 -817.  Tier 3 permitted graywater systems can treat the graywater of multiple households.

If 30 households shared a graywater system that cost $1,500 to be permitted, the cost per household for the permit would be $50 per household, the same as a Tier 1 application fee.  The annual renewal costs for 20 households to share a Tier 3 system (imagining their annual fee was on the high end– $800) would be $40/household, equivalent of the Tier 1 annual fee.  Recode encourages communities to think creatively about how to reuse their graywater. Imagine a shared treatment system for a neighborhood block that connects to one treatment system that nourishes a neighborhood greenhouse, pond and shared cistern for watering individual gardens.

Check out the fact sheets from the DEQ explaining the graywater permitting process and homeowners guide to graywater reuse.

 

Recode successfully legalized site-built (i.e. built custom to the location or nonproprietary) composting toilets & non-NSF certified composting toilets through the Reach Code in 2011.  The Reach Code Amendment submitted by Recode, includes performance testing standards requiring a moisture test (<75% moisture) and fecal coliform test (<200 fecal coliforms/gram) after the first batch of treatment is complete, the same tests required by NSF certification.
