Thanks. That is helpful way to look at it. The challenge in the area I am planting this is communication and then quality control. I’ve written a complete guide with photos on how to build, start, and maintain the system. It is being translated into other local languages now. Without the backing of a university or foundation or NGO, the availability of equipment to precisely control the sand is really not feasible. If this system is going to be really appropriate, it must be replicable locally by the people here with what they have available. Those are my personal constraints I’m working with.
I’ll try to keep tabs on the flow rates, but that is a challenge due to locations and the people monitoring it.
