The Invisible Shield, a four-part documentary series from RadicalMedia made possible by Bloomberg Philanthropies, reveals how the field of public health has saved countless lives in the U.S., protecting people from the constant threat of disease and increasing lifespans. The series explores the hidden public health infrastructure that makes modern life possible. It highlights the thousands of unsung heroes — physicians, nurses, scientists, activists, reformers, engineers, and government officials — who work together to improve health outcomes, from the days of cholera and smallpox through the most recent battle with COVID-19.
The Invisible Shield premieres Tuesday, March 26, 2024, 10-11 p.m. ET (check local listings) on PBS, with all four episodes available for streaming on PBS.org and the PBS App.
Recording Available When: Feb 5, 2024 10:00 AM Hawaii Topic: Eco-friendly sewage options; including treatment wetlands; willow system options and source separation technologies.
Féidhlim Harty is an environmental consultant and writer. His company, FH Wetland Systems, established in 1996, offers designs and guidance on waterway repair and rewilding, eco-friendly wastewater treatment training and education, and holistic landuse management for catchment protection and regeneration.
As we increasingly recognise the role of our species and society in shaping our landscapes, we see the impacts of past decisions on the ecosystems and other species with whom we share this beautiful planet. We know at a deep level that simply sustaining our current cultural norms is no longer desirable. Thus we need to look beyond sustainability (simply not dying) and towards regenerative solutions in every area of our lives and culture. The solutions offered on this website are among the best regenerative tools and techniques for addressing water and waterway management, as well as farm-scale and catchment scale solutions for cultivating a world that works with nature rather than against.
A question was asked during the session – “In terms of reduction of TSS, NH3, NO3, TP, BOD etc. I’d propose that a standard sized domestic scale system, whether constructed wetland, gravel reed bed or vertical flow reed bed, will achieve secondary treatment standard if sized appropriately. In the Irish context I propose that the EPA recommended size of 5m2/pe be increased to about 8m2/pe to achieve this standard, but the general principle applies nonetheless.
A much more thorough breakdown of figures is presented in Kadlec and Wallace’s Treatment Wetlands.
I hope that helps to answer that question raised at the end of the talk.
Kind regards and thanks again,

I forgot to mention that Septic Tank Options and Alternatives was written as an overview of options available for sanitation which may be of use to the people preparing Codes for their areas. It is written mainly in the Irish context, but applicable anywhere where flush toilets are the norm. My working title was “The unofficial EPA Guide to Wastewater Treatment”; to include a greater overview of dry toilet options and source separation options than our official EPA Code gives.
I’m also offering training this spring, looking at wastewater treatment (much of which we already covered yesterday) and water flows in the wider landscape (what I was beginning to look at in the closing part of yesterday’s talk) and EcoVisioning, which looks more at our attitudes around the various planetary challenges, and how to hold a clear coherent vision for a positive future. http://www.wetlandsystems.ie/Next%20Workshop.html “
A reminder to all that January 24-27, 2024 is the Water and Wastewater Education Transport and Training Expo in Indianapolis. We will be providing information about all the education sessions we are hosting on the 24th and 25th shortly.
But in the meantime here is a Registration discount code. Do stop by and visit our Booth!
WATER IS WATER – NOT WASTE! International Options for Smart Wastewater Treatment Decisions
WasteWater Education 501(c)3
For many small communities in Hawaii, the US, and overseas, the central wastewater infra-structure is not always affordable, geologically impossible to construct, and financially unsustainable with local resources. WasteWater Education 501(c)3, with 21 years of operation, provides access to education and resources that increase public awareness of the link between appropriate wastewater systems and (1) clean drinking water, (2) safe recreational waters, (3) environmentally sustainable surface, and (4) groundwater with watershed-based best management practices. WasteWater Education emphasizes water resource management and reuse strategies given the increasing impacts of climate change. Extreme weather events impact maintenance, operations and water availability and use. Resource recovery and building ‘smart’ should be prevalent in the design process. Webinar attendees will hear from our Board of Directors, who are international professionals, on how issues affecting Hawaii have been addressed worldwide and how the lessons learned can be put into practice here. Speakers: Ben Kele: Board Chair. Director at Arris Water, Rockhampton, Australia Director and co-founder of Arris Water. Oliver Grievson: Vice Chair. Associate Director at AtkinsRéalis and a Royal Academy of Engineering Visiting Professor at the University of Exeter. Lesley Desjardins: Board Secretary. Executive Director Western Canada Onsite Wastewater Management Association. Richard Flynn: Board Member. Past Chairman at Irish Onsite Wastewater Association (IOWA). Vice President CABEVice President CABE. Dendra J. Best: Executive Director, Wastewater Education 501(c)3. HWEA, ASTM D-19, NEHA, CCH Board.
Welcome! You are invited to join a webinar: On-site & Decentralised Wastewater: International Perspectives. After registering, you will receive a confirmation email.
Speakers: Ben Kele, Sara Heger, Anish Jantria, Jerry Hanna, Lawrence Gill.
