Cistern water level monitor

The cistern in front of Ban Mae has a steel lid 1.2 x 1.2 m approx. weight is about 10 kg. If we want to know water level in the cistern, we need to lift it every time. It would be better to have a water level monitor we could easily see every time we…


The composting toilet for the floating house is done

A few weeks ago, our team of construction workers finished building us a custom composting toilet for the BaanLoiNaam (the floating house). I am always impressed with their woodworking skills, and really complemented them on this one. The basic approach we are using here is based on the traditional “Loveable Loo” eco toilet as described…


Building a composting hacienda

The cages we built quite a while back for the compost piles we’ve had going for about two years have been almost perpetually overflowing, so I’ve been thinking for some time now that it is time to build something bigger and more permanent. In addition, it seems like a good idea to build a roof…


Composting toilet update: building some additional holding tanks

We’ve been using the composting toilet in BaanRimNaam since we moved in late in December last year, and I like it a lot. Call me weird (many of my friends have), but I really like understanding and implementing the full path of our food from growing to cooking to eating to … well processing it…


Using a siphon to control the water level in the planter box

In exploring the idea of using the cattails in the bathroom of BaanLoiNaam as a kind of constructed wetland water filter for the grey water coming out of the sink and shower, I was consulting with Bob Crosby of Biorealis and he mentioned something interesting about siphons. The idea is that in a wetland like…


Replanting the “green wall” in the floating house

Last week, we finally had the painter paint the floors in the bathroom of BaanLoiNaam. This is the same guy who did the amazing job on the blue water tank, painting it to blend in with the wooden walls. The floors are made from Shera board, which is meant to be a nice weather resistant…


Building the shower floor in the floating house

We designed a simple wooden structure to form the floor of the shower in BaanLoiNaam and the workers finished building it last week. I’m pretty surprised how nice the wood came out. The concept of this shower is a little unusual. Being a floating house that is designed to be mobile, there are no sewage…


Adding worms to the composting toilet in BaanRimNaam

Back in August before we started building the composting toilet in BaanRimNaam, I mentioned that the plans we bought were designed for vermicomposting (composting with worms). But when we moved in around New Year’s I decided to just start using the toilet without the worms. Best case is that it would compost, but more slowly….


Finalizing the composting toilet

One of the most interesting aspects of moving in to BaanRimNaam was getting the composting toilet ready for actual use. Unfortunately, I left this for after dark, so the mosquitoes were chewing me up, but the process was fairly straightforward (albeit somewhat improvised). For the tank down below the house where the composting will occur…


Using reclaimed water

Now that the rainy season is over, there isn’t very much rain water collected from the roof of BaanMae anymore. But we have a sewage processing system that first reduces the biological oxygen demand (BOD) using an aerobic treatment system, then runs it through a slow sand filter to fully sterilize it. The next step…
