Urine Diversion System (UDS)

Overview

Urine is by far the biggest volume filler as an individual urinates ten times more per annum (approximately 500 liters per person per annum) than what he excretes (approximately 50 Liters per person per annum). Urine is sterile and not a threat to mankind.

In a low water table area, an unsealed 1.5 cubic meter lined pit size for a family of 5 to 6  without removing any of the excreta will give the same life span as a 3 cubic meter wet pit.  Importantly the household members should be educated in the sound management of their toilet and no foreign objects and or grey water should be used in the pit.

In a high water table area, a sealed 3 cubic meter wet pit for a family of 5 to 6 people without any evaporation, will not last more than 12 to 15 months.  This calculation excludes additional grey water that will enter the pit if the household is not educated by the municipality’s sanitation task team or by private enterprise.

It is highly important to note that should a dry pit become wet due to abuse it can be turned into a dry pit again by making use of an effective separating system that will channel all fluids out of the pit.

Amalooloo simplifies the Urine Diversion System through the original UDS appearing as an ordinary toilet pot, but with the key difference to collect the urine at the bottom of the pot while the solid faeces falls through to the pit. The user does not have to do anything to assist the process. The main purpose of the UDS is to create a holistic sanitation system that operates only on natural environment conditions and to significantly expand the lifespan of sealed and open pits.

This project has enabled Amalooloo together with DWAF to make a breakthrough in technology.

The user feedback is very positive on hygiene, smell and free of flies. This is also a closed system that protects the individuals from sanitation related diseases.

This is not the end of this project. The next step is to present this results and outcomes of this investigation to the Minister of the Department of Water Affairs and Forestry for her recommendation. Thereafter it will be advertised and implemented in the municipalities of South Africa.

This is not only a breakthrough for South Africa, but can also be implemented in countries all over the world. (J.R. Herselman)

Unique Design Technologies and Features of the Amalooloo Pedestal in conjunction with the Ecological System

  • A toilet pedestal having:
    • an upper opening over which a person may be seated for use;
    • a lower opening substantially aligned with the upper opening; and
    • an upwardly open channel peripherally around the lower opening, the channel having an outlet opening.
  • A toilet pedestal in which inner sides or a side wall of the toilet pedestal below the upper opening leads into the open channel so as to guide liquid running down the sides or side wall into the open channel.
  • A toilet pedestal in which the channel is integral with the side wall, the channel extending along the inner periphery of the side wall.
  • A toilet pedestal in which the channel is separate from the side wall, a lower end of the toilet pedestal being aligned with the channel.
  • A toilet pedestal in which the channel is formed in a collar rotatably receivable around the lower opening to adjust the orientation of the outlet opening
  • A toilet pedestal in which the channel has a grid or sieve over it, the grid or sieve allowing liquid to pass through, but not solids.
  • A toilet pedestal in which the channel is inclined relative to the horizontal having the outlet opening at a lower portion thereof.
  • A pit latrine which includes a toilet pedestal inclusive, the toilet pedestal being mounted over a pit such that the lower opening of the toilet pedestal is in communication with the pit.
  • A pit latrine in which the outlet opening of the channel is oriented to direct urine to an ecologically acceptable or friendly disposal zone in the form of a planted area for use as a growing medium and fertiliser by plants.
  • A pit latrine in which the outlet opening is in fluid flow communication with a manifold having a plurality of branches, the branches having outlets proximate the ecologically acceptable disposal zone.
  • A pit latrine which includes a distributor for distributing liquid in predetermined ratios, for example equally, to the respective branches.
  • A pit latrine as claimed which includes a liquid receptacle for receiving grey water and which is in flow communication with the manifold.
  • A pit latrine as claimed in inclusive, which includes a hand wash basin having an outlet in flow communication with a side wall of the toilet pedestal leading to the channel.
  • A pit latrine as claimed in said flow communication is via a reservoir immediately downstream of the hand wash basin outlet for accumulating hand wash water, and having an outlet which is selectively open-able and close-able.
  • A method of disposal of human excreta using a toilet pedestal, the method including the steps of:
    • directing solid excreta through a lower opening of the toilet pedestal;
    • guiding liquid excreta into an upwardly open channel peripherally around the lower opening; and
    • directing the liquid excreta out of an outlet opening in the channel.
  • A method which includes the step of directing the liquid excreta away from the toilet pedestal to an ecologically acceptable or friendly disposal zone, for example to a planted area for use as fertiliser by plants (Ecological System)
