The Problem l United Nations Millennium Goal #7: – reduce by half the proportion of people without access to safe drinking water by 2015.
Address a component of the problem l 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.
Existing Software: EPANet l l Can perform extended period simulations of hydraulic behavior GUI written in Delphi Hydraulics engine written in C Simulation output is graphical
EPANet (contd. ) l Screen shot: nodes pipes
EPANet too limited l GUI issues: – – – l 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 l need to be able to turn taps on and off at will
Agua. RED l l Re-writing GUI and interface to EPANet hydraulics engine Using C# – – l 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
Data Flow (1 of 3) l 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
Data Flow (2 of 3) l l input node data into program and program automatically creates network from GPS points engineer can manually modify network if necessary
Data Flow (3 of 3) l l 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
