EXHIBIT #1 Work Order Number Water Distribution System Modeling Support PROJECT UNDERSTANDING Indian River County Utilities (IRCU) desires to update their water system hydraulic model to reflect current GIS (Geographical Information System) data and better represent their current water distribution system configuration. The existing water system model is in an older version of WaterCAD format, but is outdated and does not reflect current system configuration. In order to integrate the GIS data into a water system hydraulic model, GIS shapefiles will need to be imported into WaterGEMS in order to provide a basis for water system hydraulic modeling and planning. Consultant will prepare a working water system model in WaterGEMS due to its more robust capabilities in developing new models, but will provide a duplicate running model that is compatible with WaterCAD v8. The scope of services detailed below will consist of using WaterGEMS Version V8i (64-bit version), developing a working water distribution model with limited demand data and major nodes and pipe system. The scope will also consist of defining system demands based on monthly operating reports (MOR's), pump station flows and capacities, fire flow requirements, and system design criteria. SCOPE OF SERVICES Task 1 Collect Information and Import GIS Shapefiles into WaterGEMS • Consultant will attend up to three (3) coordination meetings with IRCU staff to discuss the information related to shape files, and information relevant to the development of the new hydraulic model. • Consultant will identify the service area to be studied and prepare a map with its boundaries based on information and discussions with IRCU staff. • Using the ModelBuilder feature of WaterGEMS, Consultant will create a hydraulic model network of the existing water distribution system from the latest GIS shape file provided by IRCU. The new physical alternative of the hydraulic model will consist of o Existing pipes that are 6 -inch in diameter and larger. o Junctions associated with pipes and GIS shapefiles o Tanks (WTP and remote elevated reservoirs — Roseland, Oslo, 58th Ave) o Valves and hydrants • Consultant will use ModelBuilder to provide connectivity of pipe system and nodes. Consultant will work with IRCU staff (IRCU staff to update GIS files if necessary) should pipe connectivity not be possible based on the assumption pipe ends (nodes) to be within 0.1 ft. Up to 20 hours of effort is designated for this task, assuming that the pipes ends are within 0.1 ft and significant effort beyond this amount should be considered additional services KXWPB CiviaC3eneral\Milier\indian River CountyVVRCU Water System Modeling Preparation KHA Scope rev3.doc PAGE - 1 -
