Simple supply-demand water planning

Summary: 

Build an open-source supply-demand planning tool that chooses the least-cost long-term schedule of supply-demand investments that allow meeting projected demand.

   The Supply-demand model suggests:
  • which supply-demand options to choose
  • the extent of their implementation
  • their start date
 The model minimizes the capital, operating (fixed & variable), social and environmental costs and chooses the least cost portfolio of measures and their annual implementation schedule. For more information, see our slideshow presented to the Water Hackathon London judging panel.

Why we are working on this problem: 
  • Imagine it's your job to design a 25 to 50 year water supply plan for region X or country Y
  • Economists and engineers have helped you estimate the capital, operating, social and environmental costs of the different options
  • What new supplies and what demand management (conservation) measures should be put in place?, when? at what capacity? to ensure future supply > demand 
  • There is no easy tool out there for water planners, particularly in developing countries, to use

What we accomplished during the event: 

Built the model as a GAMS code and HydroPlatform add-in.

Hi,

 

Really interesting and promising project. I try to do that myself within my basic household realm with a small network of water butts ! Have started building an Arduino platform to collect info for sharing and do some forecasting.

Your projest is showing the path:

- What info do we need to manage supply-demand at regional level ? (sensors)

- What model works best if we want to do some forecasting ? (sustainability)

But also, it enables some thinking about two other aspects:

- Actuator, how can we translate the decision outcome into effective actions ?

- Social decision making, does the model take all interest groups into account ?

Being skilled in MCDA and MCDS based on outranking method, I may bring some other views unless you have already the expert available.

By the way, have been working in Mongolia where water is becoming a major issue. As they say over there: "He who brings rain, brings luck".
