Analyze existing GIS data and compare to the existing model to identify areas with discrepancies and locations. The selected consultant will be required to coordinate with City GIS personnel to review existing relevant data. After a comprehensive review, work with city personnel to identify any discrepancies between the data and the model, and update the model. • The city has the following data available for updating and calibrating the model: ▪ SCADA system records from flow meters on entry points from contributing communities. ▪ SCADA system records from intake at Wastewater Treatment Plant. ▪ SCADA system records from all lift stations. Lift station data includes wet well level and outflows. ▪ Data from five ‘SmartCover’ devices that recorded depth at various locations. ▪ Data from four Flo-Dar meters in the island area. Two of these can be relocated as needed. ▪ Water meter usage data within Logan City. • The consultant will be required to analyze the data and if necessary coordinate with contributing communities about flow data into the City system as well as projected growth in those communities. The consultant will recommend improvements to meet projected growth and existing flows at those entry points. • The consultant will review system and identify areas to meter in order to determine inflow & infiltration in specific areas and diurnal curves for specific land uses. Coordinate of land use types with those used in the Drinking Water Master Plan and the General Plan. At a minimum include detached residential, mixed residential, commercial, and industrial land use types. Provide a recommended number of anticipated metering locations and associated costs.
