Judges'' comments
Thank you for participating in the 2015 Climate CoLab Urban Energy Efficiency contest, and for the time you spent in creating and revising your entry.
The Judges have strongly considered your proposal in this second round of evaluation, and have chosen to not advance it as a Finalist for this contest.
We, the Judges and contest Fellows, are truly grateful for your contribution to the Climate CoLab and for your commitment to address climate change.
We encourage you to keep developing your work. Transfer it to the Proposal Workspace to re-open it, make edits, add collaborators, and even submit it into a future contest. You can do so by logging into your account, opening your proposal, selecting the Admin tab, and clicking “Move proposal”.
We hope you will stay involved in the Climate CoLab community. Please support and comment on proposals that have been named Finalists and vote for which proposal you would like to be nominated as the contest’s Popular Choice Winner.
If you have questions, please contact the Climate CoLab staff at admin@climatecolab.org
Keep up the great work. And thank you again for being a part of this mission to harness the world’s collective efforts to develop and share innovative climate change solutions.

1)The WHO has set the standard water consumption per person to 50 litres per person per day (l/p/d)yet the developed world consumes 305 l/p/d and the developing world 34 - 65 l/p/d. https://improveinternational.wordpress.com/2014/04/27/how-much-water-is-enough-determining-realistic-water-use-in-developing-countries/ Fortunately the developed world has developed ways to achieve an urban lifestyle without an equal requirement of water consumption per capita. Unfortunately this technologies such as aerating tapes, low water volume toilets and grey water recycling are still being denied the developed world. Statistics have shown that with increased supply of water there is a corresponding increase in the consumption. A family that had to get water from a communal bore hole would have a marked increase in consumption when they where served with single tap within their compound. As much as you are looking to bring water closer to the people you need to look at how to mitigate against the expected increase in consumption.
2)This proposal has merit if the situation on the ground has been described correctly. If water use is unmetered until post-metered, it is likely to be wasted. Moving to pre-paid clarifies the feedback and will definitely result in less water use. And I agree it might be more useful in finding leaks. While the carbon savings from more limited electric pump use is certain, the benefit might be small as compared with the value of preservation of possible scarce water.

No clear linkage between replacement of gasoline with renewable energy and the Prepaid Water Metering System. Team STIC to focus the action on piloting in a smaller community to access the impact before deployment to the rest of Tanzania and for that matter Africa. No clear feasibility. Presentation does not give a clear picture and focus.
The project name is misleading as it mentions Desalination System which are not mentioned in the body of the proposal.
A need to move from post paid to prepaid has very little to do with wastage or even identification of leakages in the lines but more to reduce the cash problems that they cause the supply companies.
To detect leakage what is needed is intelligent bulk meters that can be polled centrally so as to reconcile water volumes. After the bulk level if resolved you can then move closer to the retail consumer.
Most well designed community water supply systems are 100% gravity fed, if pumps are involved the main issue is how to reduce dependency of the pumps, unfortunately this will become a political issue as the person who supplies the diesel and services the pumps is influential enough to kill the discussion at source.
