What our Design Intended to Address
Provide a modification of current methods
Put waste out of human contact
Neutralize the fecal waste for safety
Design Components
Gas Exhaust
Scent control
Prevent dissolution of gasses to
kill bacteria
Concrete Toilet Seat and Bowl
Stable
Water Resistant
Longevity
Fluid Outflow
Tank
Contain waste without overflow, this is
buried underground
Pressure from the fluid within
the tank will passively leach into
the surrounding soil.
Product Components
Gas Exhaust
Concrete Toilet Seat and Bowl
Carbon filtration handled the
scent issues, however there
were concerns of replacement
options.
Concrete molding process
needs refinement, coating
proved to be a viable solution
to keeping the material clean.
Fluid Outflow
Design was changed to address
Pascal’s Law. Potential for
another bend to prevent
gravitational clogs.
Tank
Material strength handled the
necessary mass of fluid expected.
Previous Test Results
Confirmation that
- Waterproofing concrete is possible
- The tank will not fill over half full given any intake of fluid volume
- It is possible to induce bacterial metabolization underground
Testing Stage 2
Goals:
- Create a version of product above ground
- Mold our seat in actual size and coat it
- Test the wear resistance of the coating
- Determine that the waste will be processed before release into the
environment
Concrete Molding Issues
Concrete Particle size must be small
Needs higher moisture content during cure
Silicon or Plasticine mold to create smooth surface
Crumbling results in premature wear on coating
Waste Processing Within Tank
Issues Raised
This solution seems very simple, does that inherently mean it has an invisible
flaw?
Why is this better than just a septic tank? What sets this apart from an average
septic tank?
Is this truly viable?
