Wanted: Key Documents for Re-Use Standards (Latin America and the Caribbean)

Dear experts,

I am looking for sectorial re-use standards for treated wastewater and greywater for multiple purposes (irrigation, industries such as oil refineries, and also drinking water). The region I am reasearching for is Latin America and the Caribbean, hence if anyone could point to region-specific standards, that would be even better!

Hoepfully I explained myself well enough, the question is rather broad but at this point any document / webpage would help.

Thank you all,
Alice

Re: Wanted: Key Documents for Re-Use Standards (Latin America and the Caribbean)

Hi, Alice,

Please have a look at the WE Stand international green code passed by IAPMO/ANSI in 2017.  Entitled Water Efficiency and Sanitation Standard for the Built Environment, this standard is now available for jurisdictions to adopt and apply. It provides minimum requirements for water use practices that maintain protection to public health, safety, and welfare. It applies to residential and commercial buildings, indoors and outdoors. It contains the first set of comprehensive codified requirements for composting and urine diversion toilets and progressive provisions for uses of grey water from clothes washers in landscape irrigation.  The link to purchase the study is here:

iapmomembership.org/index.php?page=shop....edirected=1&Itemid=3  

Portland, Oregon-based Recode released “Model Code for Composting and Urine Diverting Toilets” as a public domain document before submitting its draft to IAPMO. While some language was moved and changed, the underlying content and requirements match the essence of the code ultimately accepted. It is available on Recode’s website here: 

www.recodenow.org/wp-content/uploads/201...d-Draft-Document.pdf

 The active, community-managed,  container-based toilet system at Kailash Ecovillage in a populated neighborhood of Portland, Oregon is based on the WE Stand Code and is authorized by the City of Portland and the State of Oregon.  Information and operations manuals are available at links listed on the page "Changing Codes and Regulations"  below.

Good luck with your search for code that is ready to use in Latin America. I hope you'll share the most promising resources in this thread.

Toilet availability is a human right and well-designed sanitation systems restore health to our cities, our waters and our soils.

Hi Alice, 
For greywater re-use standards for Malawi, and our case study, please see:

Re: Wanted: Key Documents for Re-Use Standards for treated wastewater and greywater (Latin America and the Caribbean)

Hi Alice,
Have you already found what you're looking for? And why are you looking for those documents if you don't mind me asking?
It's a very broad field if you are researching all those different reuse applications (including oil refineries and drinking water). I think in most of the documents that we have shared here on the forum it's just about reuse in agriculture. And of course treated greywater reuse is very different to treated wastewater reuse (greywater much lower risk than wastewater).

You have probably already looked through the documents mentioned here:
forum.susana.org/40-greywater-blackwater...reuse-and-irrigation

Was this publication useful for you?:
WHO (2016). Sanitation safety planning. Manual for safe use and disposal of wastewater, greywater and excreta. World Health Organization (WHO), Geneva, Switzerland, ISBN 978 92 4 154924 0
www.susana.org/en/resources/library/details/2443

Sanitation Safety Planning is a tool to help sanitation system operators maximise health benefits and minimise health risk of their system. It guides operators to prioritize and target risk management efforts to where it will have the most impact and to improve over time. The outputs can be used to provide assurance to the public and authorities of the system performance based on sound risk based management.

We also have this sub-category, maybe some useful publications there:
forum.susana.org/174-safety-of-reuse-asp...-guidelines-policies

Do let us know what you find. Probably each country in Latin America has its own guidelines.

Hi Alice
My Master's dissertation was about greywateŕ reuse and I cited the main standards/guidelines and legislations of water reuse and greywater reuse in Brazil country and at state or city levels.
Please find here the publication derived from this research:
https://doi.org/10.1016/j.jclepro.2016.07.162
I also could indicate some additional sources and send you the pdf of the paper.

Best regards
