  1. Review inventory of the networks and ground features from available BSWB records and maps of the towns.
  2. Establish the network and appurtenances (ground-truthing) and come up with an updated network of the metropolis (GIS mapping).
  3. Determine distances and elevations of key nodal points in the network as well as location and elevation of key system components and to also determine roughness factors and losses associated with each.
  4. Determine the demand for supply service for each area or sub-areas of the network and compare with what is currently available.
  5. Identify and propose suitable software(s) for the modeling and analysis of the networks and deployment and installation of same. The software to be deployed should meet the requirement/characteristics including but not limited to effectively carry out hydraulic modeling for a minimum of 10,000 pipes and 10,000 nodes, handle all network control elements like check valves, shutoff valves, pressure release valves, pressure sustaining valves, different shapes of storage tanks (circular, rectangular,….), elevated and ground reservoirs; elements like fixed and variable speed pumps, ability to calculate energy consumption, color coding of the network based on available pressures and flow velocity. The software should be able to carry out water quality modeling for some chemicals like Chlorine residual, Aluminum residual, Sulphate residual, etc. The software should be flexible enough to interface with some GIS/CAD softwares. As well as deployment of appropriate hardware (one desktop computer), among others.
