Position Summary:


Under limited supervision of the Director of Engineering & Construction, the Hydraulic Modeling Engineer (HME) utilizes specialized technical skills in design, data capture/data conversion and maintenance, spatial analysis, system implementation, training, and application development to build, operate, maintain, and analyze high-accuracy base models for water distribution and wastewater collection systems hydraulics.  The HME also provides engineering support for the New Development Program and oversees final review and approval of submitted development projects while maintaining the company’s standard construction details and Minimum Standards.  This position is complex in nature, mostly unstructured, with some routine work and requires use of independent discretion and judgment in performing the assigned duties.    


Essential Functions:

  • Prepare and perform various static and extended period hydraulic model simulations for water and wastewater systems as required by CWS engineering and operations staff.  Many times this involves piecing together vague and incomplete data to form reasonable, educated conclusions. Prepare and evaluate various models for engineering application of hydraulics, water quality, and fluid dynamics in water and wastewater systems and make recommendations for their implementation.  Identify and document model data gaps and troubleshoot real world operational issues by developing innovative alternative solutions and evaluating the advantages and disadvantages of those alternatives. Provide written hydraulic model reports with recommendations to engineering and operations staff. Support hydraulic modeling needs of CWS Master Plans, Major Capital Improvement Projects, New Development Program, and requests of CWS upper management. Work with in-house and contract field technicians to collect and verify field data, including calibration measurements and SCADA data, and develop techniques to improve the overall production thereof and integrate such data into hydraulic models. Interface model geometry with the company’s G.I.S. database to ensure hydraulic model geometries are comprehensive and inclusive of new system additions and modifications. Work with Information Technology Department (IT) to create and develop customized programs for obtaining model related water/wastewater usage data from other CWS database compatible applications. Produce working AutoCAD drawings and draft finished drawings as required to support engineering staff. Includes accurate hard copy maps for field use as well as maps for presentational purposes. Conducts final review and approval of New Development plans submitted for SCDHEC construction permitting under CWS’ Delegated Review Program (DRP) and ensures designs are in conformance with CWS Minimum Standards for the Design and Construction of Water and Wastewater Systems (Minimum Standards). Assists in determining availability and non-availability of water and wastewater service for New Development project requests. Manages, updates, and maintains CWS Minimum Standards and all associated water and wastewater standard construction details as necessary and in accordance with regulatory requirements. Perform all drafting activities associated with maintaining CWS standard construction details using AutoCAD software. Conducts written and verbal communication with developers and developer engineers regarding issues with New Development projects as required. Provide technical assistance as it relates to hydraulic modeling and the New Development Program to other engineers, surveyors, technicians, developers and others involved in CWS business.
