The scope of services will vary according to WASD’s needs and will include but not limited to the following potential tasks: 1. Assist with estimating future water and sewer flows (demands) and the corresponding infrastructure requirements for specific geographic areas and/or Countywide. 2. Review WASD’s hydraulic models (water and wastewater), including processes and procedures. The selected consultant may be responsible for updating and maintaining WASD’s hydraulic models (Innovyze InfoWater and InfoWorks ICM). Representative inputs and tasks may include: a. Water consumption data from WASD’s Customer Care and Billing System; b. Data from WASD’s SCADA (Supervisory Control and Data Acquisition) system, including flow, pressure, level, and equipment operation; c. Developer agreements and corresponding flow demands/contributions; d. Hydraulic attributes of new infrastructure, including pump curves; e. Periodic validation and integration of WASD’s data streams to ensure accurate model outputs. These outputs will inform planning efforts to identify current and future capacity constraints and recommend upgrades for inclusion in WASD’s Capital Improvement Program. 3. Perform hydraulic modeling of the water transmission/distribution and wastewater collection/transmission systems, including: a. Evaluation of development projects to ensure adequate capacity and to define design conditions for new facilities; b. Flow projections; c. Model calibration and/or validation; d. Hydraulic analysis; e. Process modeling; f. Analysis of raw water transmission to treatment plants...
