Health Sanitation Systems

This page pertains to possibly the most important and basic system, and includes vital information not included in pages regarding other systems. 


Please scroll down to see the diagrams which are spread out throughout the message. 

         HEALTH Sanitation Systems is a project that began several years ago after Google advertised for ideas that would help the most people in our world, and therewith gave as an example of a special innovation, an easier way of transporting water.  In trying to find an innovation somewhat like that,  and something that could help many poor people, various innovations regarding both sanitation and composting sprung forth as extensively discussed and shown below.

         HEALTH Sanitation Systems are not only intended to provide better sanitation, but also to provide compost and fertilizer.  It is said that one third of our world lacks proper sanitation (being two billion persons), and said that four thousand children die daily because of a lack of proper sanitation.  Further many more die daily because of a lack of proper food.   If it were only one half that bad, proper sanitation, and enhancing soil and gardens, would still be a very important subject.  I believe many people would be glad to donate some funds, if they were assured that even a small donation could help spare the very poor of our world from needless pollution and disease, as well as famine because of depleted soil.  If a system that could easily and inexpensively help provide sanitation, as well as creating quality fertilizer, was taken on by some foreign aid groups, it would appear that people would donate to those aid groups.  I myself would be willing to donate several thousand dollars toward getting this project into production, and out to where it needs to be.  For some reason money seems to get many people's attention more than almost anything else, and is the reason money is spoken of here.  Yet may people's needs get our attention more than money.   If less pollution and more food would be worth as little as one dollar per person to a billion poor people in our world, that would already be one billion dollars.  I give credit to GoogleSketchUp, free software, which allowed me to create the below diagrams.

       The population of us humans is much higher than most any other living species, such as dogs, cats or cattle, thus human waste is not a small matter.  It is surprising how much waste the human family creates.  A village of 500 creates around 45 tons of solid waste and 90 tons of liquid waste annually (figuring eight ounces of solid waste, and 16 ounces of liquid waste per person per day).  That 135 tons of waste for every village of 500, can either result in much polluted water and health hazards, or could provide much needed compost and fertilizer, and thus nutrition and health.  That total of 135 tons of waste when combined with the additional soil used to sanitarily deal with the waste, after being composted would go a long ways toward providing safe and quality fertilizer for that village.  Regarding a city of one million people it creates 90,000 tons of solid waste and 180,000 tons of liquid waste annually, or 270,000 tons of waste each year.  Such is equal to 13,500 truck loads each year, or around 37 truck loads daily (20 tons per truck).  Yes, human waste, although often thought of as an insignificant thing, if dealt with carelessly can result in much pollution, or if dealt with rightly can result in much compost and fertilizer.  Further the world's population is equal to six thousand cities of one million each, and thus creating equal to 222,000 truckloads of waste daily. 

 Figure 121 


        The object of the sanitation system shown here is to help prevent pollution, and rather create compost fertilizer, and in a manner that even the poorest of the world can readily participate in.  Some important features of this sanitation system are as follows;

       Firstly very little effort should be required to use the system and while the system should be quite inexpensive.  Note, the least expensive system obviously could be much less elaborate than the systems shown here, while yet utilizing the same main features.  In this system the solid waste falls into a quite confined or narrow cell, while the liquid waste is intercepted by a unique urine tray and automatically drains back into the composting pile (see figures 141, 151).  Thus the liquid waste largely takes care of itself, while regarding the solid waste, since it falls into a quite narrow cell, little soil is required to cover it, while further this small cell traps and minimizes odor even before the waste is covered.  Waste entering a large open area simply creates much needless odor.  Note, an indoor system, largely using the same principles as spoken of here is being tried indoors, and is largely as odor free as a modern flush system, although using only several ounces of liquid to periodically flush the special urine tray that intercepts the liquid.  When the solid waste container gets full, the solid waste with the soil covering it (which mixture is normally quite dry) is emptied into the large soil-waste bin.  When the bin gets full, the small bathroom structure is simply moved ahead and follows a circular path as shown in figures 111 & 121.  Note, the emptied waste container without any cleaning, as well as the waste mound where it is dumped, has been found to be quite odorless and likely because of the soil involved, and because of the control and absence of liquid waste.  Although the mound of waste mixed with soil is basically odorless, yet for the sake of appearance and additional sanitation the waste most recently added to this mound is kept covered with a plastic or rubber sheet of some kind.  Further when the unit is pulled ahead, likely some additional soil should be thrown over the whole mound, so all waste remains covered.   Grass or something should also soon be growing on the mound.  It also appears that the composted soil and waste from the year before, could be used as covering material for the most recent waste (see figure 121).  This would further increase the system's ease of use, as little outside soil (and possibly none) would need to be found for the system, because the system would be creating it's own sanitary covering material.   


Figure 131

        In some systems the solid waste receptacle beneath the stool is like a four cell bucket, which has capacity of around 30 solid waste uses, (see figure 141).  In other models it might be a smaller one cell container set on a arm or tract that can be emptied by pulling a rope, or if automated possibly by simply pressing a button. This system largely and simply follows the principle of Deuteronomy 23:13 (yet in a very convenient manner), and which reads, " And thou shalt have a paddle upon thy weapon; and it shall be, when thou wilt ease thyself abroad, thou shalt dig therewith, and shalt turn back and cover that which cometh from thee:".    Sanitation Systems that use soil to cover the waste, possibly should be called "Deuteronomy Sanitations Systems".  Regarding many of the very poor in our world, they seem to not be able to fix anything mechanical when it breaks, while also being too poor to have anything more than the very basics.  Thus one of the most simple sanitation systems would likely be best for them.

        In many situations, to simply deposit human waste into water and then use water to flush it away is very unsanitary as it ends up spreading the harmful pollution or pathogens around, unless that water is carefully regulated and disposed of.  When human waste is deposited into water, instead of only needing to deal with only a small amount of waste, now much liquid waste needs to be regulated and rightly disposed of.  Even in America, septic systems too often cannot get rid of all the polluted water and thus raw sewer water ends up running into ditches, streams, ponds, and lakes.  Further in many places in our world, water often is simply far too scarce and precious to use it for depositing waste into.  Thus in many situations the Deuteronomy 23:13 system needs to be used, and it works.  Obviously systems as shown in figures 111&121, should be kept on higher ground, to prevent flooding or running water from contacting the waste and water being contaminated.

        Another feature of Health Sanitation Systems (HSS) is their commodes are designed with a special gate that fully isolates the solid waste area, and which gate can and should remain closed even when the commode is being used for liquid waste (see figure 151).  Thus the solid waste area is most always fully isolated.  This gate could be made to automatically close whenever the commode lid is closed, and then remain closed until the side lever is lifted (see figure 151).  Regarding sanitation for commodes when used for liquid waste, it has been found that the urine tray remains largely odorless simply by flushing it periodically using a squeeze bulb and squirting just a little vinegar mixed with water over the urine tray area.  An automatically filling squeeze bulb on a hose could be used for flushing (see figures 131 & 161).  Other sanitizers could also be added to the water.  HSS does not promote large or separate urinals, for the sake of simplicity and because the more surface or apparatus,waste makes contact with, the more potential for odor and more area that needs flushed or cleaned.   The extra height of HHS commodes makes them work even better for men's urinals, resulting in less need for separate urinals.  HSS commodes have a dual use, and have only a small urine tray that needs to be flushed, and which tray, both intercepts the liquid waste, as well as isolating the solid waste area. 


       Figure 151

          Although HSS has numerous new features, actually commodes that used soil to cover waste were already in use in various places years ago, and soil was well known for it's great ability to eliminate odor.  In the past soil commodes (also called earth closets) were even competing with flush commodes (water closets) in the USA.  Yet none of those commodes intercepted the liquid waste, to thus keep the solid waste container quite dry, making it easy to empty, and more sanitary (while also conserving all the space under the seat for solid waste), as the HSS commodes do.  Nor did the solid waste fall into a smaller cell to thereby allow very little soil to sanitarily cover the waste. Nor did they have a four cell container that simply could be turned when each cell was full, resulting in it being similar to the container having capacity to be filled four times, before needing to be emptied. Nor did they have a sliding gate that isolated the solid waste cell, and that would and could remain closed even when the commode was being used for liquid waste.  Nor did they incorporate an outdoor system where the liquid waste would automatically drain into the compost mound, while the solid waste easily could also be emptied onto the adjoining mound.  Nor did they incorporate the method of simply moving the structure away or ahead when the front of the mound was full, and around a circle as do the systems show here.  All these newer features and methods appear could be very helpful, especially among some peoples and places in our world, and not only for sanitation, but also for providing fertilizer.  Below are some photos of soil commodes (earth closets) as in the past.

          To provide more space for waste under the commode seat, HSS commodes (like some other commodes) set higher than standard American commodes, thus requiring a raised platform or step in front of the commode.  Although this height and step is a slight inconvenience for some uses, yet this height is a much better height when the commode is used as a men's urinal.  The unique raised platform of HSS has slots in it allowing the platform to easily be evaded when used as a men's urinal (see figure 131).

         Many details are not spoken of here.  Further many designs and possibilities have been considered which are not spoken of here. Further, various systems that do not use soil for sanitation, but rather use bagging and isolating for sanitation, and which yet basically do not use any water, are also being considered.  It appears some features of HHS could improve present day Port-A-Johns as well as other indoor systems.  Yet most of all may we remember thousands of children die daily because of a lack of sanitation while many more die because of a lack of food, while an inexpensive system based on God's Deuteronomy sanitation plan could help eliminate much of this pain and difficulty.  Billions of people need both sanitation and better soil.  May foreign aid groups also remember that the foreign aid group, who would efficiently help prevent both filth and famine, would likely get more donations.  Although HSS sees many good possibilities, HSS also knows that without outside help and interest, this project will get nowhere.  The designer's efforts and few thousand dollars will simply get nowhere without the proper contacts, and help, and interest of others.  Thus the designer is simply setting this project forth to those who might help further it.  Thus if you see this as a worthy project, your help in finding the right contacts, or providing thoughtful suggestions, or what ever you might have to contribute, if it is as simple as an encouragement, all would be much appreciated.
