As you might have seen, we run a RSS feed news aggregator at https://news.watsan.eu/ that collects all sort of updates from WASH related websites. Sadly not all websites have a syndication (RSS/Atom) feed, but many still do and we are working on implementing a feed bridge.
For now check the list of already collected feeds in the link above (left side, click to unfold the categories). Is there any interesting WASH related website that we missed? Please share links here
