Registered HydroTunnel.net for the soil filter water treatment product we will develop and promote

DC Dean Cameron Public Seen by 6

I have already gone ahead and registered HydroTunnel.net because it was available as a domain name in .NET ending and many others. It was only $18 and at least stops others from using that name and creating confusion. I don't envisage we will set up a website for the domain at this stage if ever. Mainly useful so we can communicate precisely which subproject we are talking about as a group and with the world

Dean, I'm unclear as to the labelling of the Tunnel project(s). You registered Eco-Tunnel and later Hydro-Tunnel. Are you proposing two different designs for different functions or is the name Hydro Tunnel replacing EcoTunnel for the same design?

Could you upload a diagram and description of the work-in-progress Tunnel design(s) onto this Loomio platform?

I'm prone to have an expectation that others are mind readers Richard! I have a draft design using the same tunnel elements to create a much cheaper water storage system than an above ground or below ground tank. The idea is that a geofabric protected landfill liner (a very robust plastic alloy of PP & PE ) lined trench, would have a trench arch chamber installed in the trench below a geofabric layer supporting an irrigated soil layer, with a garden planted in it. The concept is to filter both stormwater runoff and effluent from an EcoTunnel through a planted soil bed to remove nutrients and achieve potable reuse at the household scale. I will do up some CAD drawings as soon as I get a chance and post them here for comment. The theoretical basis is that stormwater runoff is typically more contaminated than the effluent from an Ecotunnel. The effluent will need nutrients removed possibly as high as 15 mg/L of total nitrogen mostly as Nitrate and up to 4 - 6 mg/Lof total P as Phosphate depending mostly on household detergents. Irrigating a food garden should remove these down to WHO acceptable levels for drinking standard. The most important benefit of this tandem treatment arrangement however is that of the about 30mm/day irrigation rate only 5mm max will be transpired or harvested as food/organic matter so 5/6th of the water from the house/building can be recycled meaning the required potable water storage volume is much smaller than would typically be required for a rainwater tank serviced facility. Once we get real data we can start to model the required storage sizes needed for different climates.
