Filter 1 is still working, and is in the process of being tested again. We are running water through it and hope to be able to have a professional testing done soon. Another pond filter will be put together this year. This will filter pond water supporting 5 medium sized fish. As we get information we will post it here on this blog.
As of June 18, 2021 we have the donation page working. Its title is “Slow sand water filter construction and operation (a summary from this blog) PDF: $7.50”. There’s a link in the header of every page. All our pages are secure, and the donation is via PayPal. We still don’t have ads on this blog, and the content of this blog is not dictated by advertisers. We are paying for all the hosting and computer expenses from our retirement income. These costs have gone up exponentially. At some point in time we will either need to have ads on this blog, obtain enough donations to pay for expenses, or simply shut it down. All our experience and discoveries will then not be available.
The weather here has been “normal”. Precipitation, and temperatures have been “normal”. We are currently starting a dry spell. Hopefully no fires will start.
I appreciate your doing this; just bought your guide. I intend to change my roof type in a future remodel (when costs go back down enough), but meanwhile I’m searching for ways to clean the ample winter rain that falls on my asphalt roof so I can consume less in our summer drought which is the new normal here in the Pacific Northwest. I will give this a try, in addition to setting up a gray water diversion system. I have about a third of an acre where I grow most of my food.
I also like your simple style, encouraging me to get my new blog up and running rather than getting stalled on choosing bells and whistles first.
Thank you for your donation, toesinthedirt. We have a composition roof surface here. We specified no embedded moss poison when it was installed. Filter 1 takes out (among other toxins) petroleum hydrocarbons leached from the roof shingles.
