How can we improve sanitation and better manage human waste in low-income urban communities? Read the challenge brief

Concept

Group buying toilets

In the same way that microfinance has leveraged group lending to ensure accountability and repayment, NGOs or even for-profit organizations can engage communities in "group buys" of toilets. Communities would pool together resources to apply for a 'toilet loan' and collectively repay that loan. If the group defaulted or didn't maintain the toilet correctly, everyone would lose free access to the toilet (the NGO or company could take over and turn the toilet into a regular public latrine).
A group of neighbors would band together and apply for toilet funding to build a toilet. They would receive detailed plans and assistance in building a hygienic latrine from a NGO or for-profit company and pay off their latrine over time (weekly or monthly payments). The latrine would only be available for use by that group of neighbors (although they collectively could decide to allow paying "non-members"). By using a group model for building / funding there is some peer pressure to keep the resource well-maintained and to repay the loan (since the toilet access will be revoked for all if they don't do so).


Benefits of this program include:
+ Unlimited access for community members means less incentive to use "flying toilets" or other unhygienic methods
+ Makes toilets affordable - while a single family might not be able to afford a good toilet, a community can
+ Sustainable funding model - community members pay for their toilets over time. Could be a for-profit model which would allow fast scaling.
+ Peer pressure for maintenance


Challenges:
- Need significant local team to distribute and monitor toilet "loans" and building
- Need to identify a good technology / building plans for the basic toilet itself

Who could implement this?

  1. Local entrepreneur
  2. Large NGO

1

How well does it meet the needs of the developing world?

It fulfills really well on the need its chosen to serve
It will help but other solutions might serve the needs better
It doesn't really address any of the needs of the developing world
2

How innovative is this concept?

It's completely new to the world
It's a good reinterpretation of an existing idea
There are some similar ideas
It's not innovative at all
3

How feasible is this concept to implement?

very high potential
It's good but need a lot of work
Its got too many open questions right now to say either way

I posted this on another post also, but orangi pilot project may have some useful implementation lessons for you to build on http://www.oppinstitutions.org/Low%20cost%20sanitation%20program%20in%20orangi.htm

Thanks Dominique! I like this concept. Not only does it help to solve the issue of financing from the buyer perspective in that the cost could be shared by a group of people but it also solves the issue of expertise. Meaning that some families may be interested in installing a toilet but have no idea how that might be accomplished. To have an organization that publicizes their local knowledge and availability to assist in directing how a toilet would be installed might be the incentive a family needs to go ahead and initiate the steps required to get a toilet installed. Very good stuff. Thanks again!

I propose teaming up with existing projects such as : www.energyincommon.org so the choices/potential are more and wider for lenders/investors.
For making administrative fees and transfer costs as low as possible.

Potential is there also for individual families to get microcredits to install a modern toilet inside their house. (Perhaps to start to gain some small income on it for letting neighbours use it)

Nice combination of group buying community responsibility and microfinance funding! More loans could be made and paid back faster if we can find a good way to generate income from fertilizer/energy creation

I like how something like this could motivate self-goveranance of a sanitation facility. Highly relevant when considering the Potty Project key insight that having a clear identity over who owns a toilet drives responsible use: http://bit.ly/fAhIet

Great idea to use analogous industry models for sanitation. Also, with so many people living in compounds, group buying is already a behavior for many when it comes to water for example.
