The slow sand filter projects documented on this website have taken place in the pacific northwest area of Washington state, USA. The first filter project (filter one) was started in early 2007. All of the projects are ongoing and will continue as long as the author is able. The water quality tests that have been(…)
Build your own STAINLESS STEEL water filter / purifier. Easy to follow instructions. All you need is a drill and a pair of tin snips. A water purifier is a must have for a wilderness cabin, off grid living or survival during power outages and SHTF situations.
Garden towers are an easy and fun way of growing food in limited space, while composting your food scraps and using them to fertilize the soil. The idea is that the plans are put in special slots cut on the side of the barrel, while food scraps are put in the perforated tube mounted inside the barrel. Then a couple of earthworms are also inserted in the tube and while they munch their way through the food scraps, they also fertilize and constantly improve the soil in the barrel.
After the treatment of the household wastewater in an Anaerobic Baffled Reactor, which will remove most of the solids and will greatly improve the quality of the effluent, the issue with the odor and with the presence of certain amount organic materials will remain and can be resolved by a small scale constructed wetland.
This article points to the results from a study of the processes involved in treating wastewater in an Anaerobic Baffled Reactor and collecting methane as a byproduct. An ABR is essentially a combination between a septic tank and a biogas reactor, whose design aims to increase the contact time with the active biomass (sludge), which in term results in improved treatment. ABRs are often used for the primary treatement of wastewater in DEWATS (DEcentralized WAstewater Treatment Systems), while a constructed wetland is used for the secondary treatement.
This article describes the heating, cooling and domestic hot water solution that I plan to implement in my small shelter. It uses solar panels to heat or preheat a closed loop antifreeze system, a wood stove with water jacket for the cold winter days, a thermal bank for heat storage and a ventilation radiator.
Getting water out from a deep well is not as simple as one would hope. This article scratches the surface on the various difficulties that one would face when trying to extract water from a well that is more than 10 meters deep and will explain how the can be easily avoided by using a rope pump.
