The Problem

• United Nations Millennium Goal 7
• reduce by half the proportion of people without
  access to safe drinking water by 2015.

3
Address a component of the problem

• Write a software package that streamlines design
  of water supply distribution systems
• takes GPS survey data as input
• designs a water supply system from the water
  source to household taps
• allows the engineer to modify the design
• tested by Agua Para el Pueblo in Honduras and
  then released for free use by organizations
  working on the Millennium Goals.

4
Existing Software EPANet

• Can perform extended period simulations of
  hydraulic behavior
• GUI written in Delphi
• Hydraulics engine written in C
• Simulation output is graphical

5
EPANet (contd.)

• Screen shot

6
EPANet too limited

• GUI issues
• difficult to input large node set from file
• does not allow easy modification of properties
  for a specific set of nodes
• only 2-D view
• Engine issues
• assumes constant water demand throughout day
• need to be able to turn taps on and off at will

7
AguaRED

• Re-writing GUI and interface to EPANet hydraulics
  engine
• Using C
• object-oriented
• ease of Windows GUI development
• Visual Studio .NET makes group development easier
  by splitting main solution into projects
• still allows us to call existing C code
• Will allow user to generate output reports of
  simulation results

8
Data Flow (1 of 3)

• Engineer walks along paths from water source to
  each house entering (x,y,z) values at various
  locations where nodes (pipe junctions, tanks,
  etc.) will be

9
Data Flow (2 of 3)

• input node data into program and program
  automatically creates network from GPS points
• engineer can manually modify network if necessary

10
Data Flow (3 of 3)

• program calculates cheapest way to connect nodes
  with pipes based on pipe material and length
• simulates network using EPANET engine to check
  that the design works
• simulation will turn taps on and off at
  intermediate time steps based on sample daily
  water usage distributions
