Campaign: Towards a Safer More Abundant Water Supply (#TASMAWS)

Recode and International Living Future Institute invite you to participate in a letter-writing/email campaign to encourage the State of Washington to adopt and implement a statewide on-site non-potable water permit program. Washington has already invested significantly towards this effort by lending the expertise of two Washington State Department of Health representatives — Stephen Deem, Regional Engineer and Mamdouh El-Aarag, Wastewater Management Section — to serve on the National Blue Ribbon Commission for Onsite Non-potable Water Systems. These commissioners, along with agency experts from 10 other states, created a series of documents to help states and/or local jurisdictions undertake this work. The state now just needs to hear from external stakeholders to move forward.

The National Blue Ribbon Commission for Onsite Non-potable Water Systems

The National Blue Ribbon Commission for Onsite Non-potable Water Systems “advances best management practices to support the use of onsite non-potable water systems within individual buildings or at the local scale. We are committed to protecting public health and the environment, and sustainably managing water—now and for future generations.”

To that end, the commission has provided a variety of tools and resources to help governmental agencies implement a permit program for onsite non-potable water systems that is more protective of public health than regulatory requirements for centralized systems. This “Risk-Based Framework for the Development of Public Health Guidance for Decentralized Non-Potable Water Systems” defines the reduction targets (called “log reduction targets” or LRTs) for a variety of different on-site waters (as well as municipal wastewater) based on the risk to human health caused by the presence of pathogens (i.e. viruses, bacteria, and protozoa).
