The Reinvented Toilet

  • Is desirable to use
  • Removes pathogens
  • Recovers energy, clean water

and nutrients in situ

  • Operates off the grid
  • Costs less than US$ 0.05 (5

cents) per user per day

The Engineering Field Testing (EFT) platform in Durban:

  • Real world testing, many users
  • Evaluates performance over an

extended period

  • Feedback from community on

suitability and impact

  • Uses the information and data

generated to improve sanitation for all

(A few of) the lessons learned…

slide-17
SLIDE 17

Testing on a platform = greater benefits than individual field tests

TECH DEVELOPERS CAN FOCUS MORE ON TECHNOLOGY, LESS ON LOGISTICS FASTER ESTABLISHMENT KNOWLEDGE SHARING COMBINE TECHNOLOGIES SHARED INFRASTRUCTURE REGULATOR SEES PERFORMANCE UNDER LOCAL CONDITIONS

slide-18
SLIDE 18
  • Accessibility
  • Space
  • Topography
  • Shared use
  • Illegal connections
  • No as-built drawings
  • Ground conditions
  • Speed vs. job creation
  • Lack of layout

flexibility

  • Unexpected issues

Site selection & preparation is challenging

slide-19
SLIDE 19
  • Political tensions
  • Security
  • Community Liaison Officers
  • Community can stop the project
  • Good community engagement

is key to success of EFT

Community support more important than technical suitability

slide-20
SLIDE 20

Managing expectations

  • Setting precedents
  • Testing has an end
  • Local employment
  • EFT can’t solve all problems
  • Timelines change a lot
  • Working hours
slide-21
SLIDE 21

Testing

  • Product standards (e.g.

recycled water quality) must be context-appropriate

  • New SOPs needed
  • Agree up front on timelines

Typical timelines

SITE PREPARATION & ESTABLISHMENT COMMISSIONING & TESTING DECOMMISSIONING

Community site

2 to 5 months

Household site

1 to 3 months Variable – a few months to

  • ne year

1 to 2 months

Note: community engagement, ethics, contracts & utilities can be lengthy!

slide-25
SLIDE 25

Recommendations

  • Don’t test on the EFT too early
  • Decide on primary aim: testing technology or testing suitability for

Durban

  • Community engagement can make or break project
  • Communicate early about design (visits are valuable)
  • Flexibility
  • Local regulations
  • Security/vandalism
  • Local procurement
  • Align expectations early (timeline, working hours, staffing…)
  • Exit strategy

…for technology developers

slide-26
SLIDE 26

Recommendations

  • Strength of municipality – private company – university partnership
  • State minimum readiness level for technologies
  • Resource planning is difficult!
  • Get communication right (internal + external)
  • Who is driving the programme?
  • Establish how EFT host city will benefit:
  • Monitoring requirements
  • Structured knowledge sharing
  • Partner with local technologies

…for setting up an EFT
