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 is to send it in to a lab to test the exact state of cleanliness of the final water. If necessary, we can add an additional UV filter for further sterilization

But whether we are using captured rain water or sterilized sewage water, we want to be able to use this water for watering non-edible plants like trees and flowers. The problem we had is that the urn that had the water often times wasn’t the closest one to the plant we wished to water.

So last week we added a system of underground water pipes connecting all of the urns together. Rain water or any other water we wish to use can be pumped into any urn and it will fill up all of the urns (or a subset if we turn off the correct valves).

Here are some pictures:

You can see the quick release hose connection on the left and the valve on the right. The valve on the right goes to the underground pipes.

Here are pictures of the other urns:

Each urn has the valve to the pipe system and the faucet for the hose. Hopefully this will make it easier to get the water to the area around the house that needs it.
