G&D is experienced in the development and application of computer hydraulic models, using a variety of software tools, to evaluate sanitary sewer collection systems for the purposes of capacity analysis, guiding I/I control programs, and capital planning. The scope of work often involves:
- Model selection;
- Establishing modeling baseline;
- Temporary flow metering to support model calibration;
- Model calibration to observed flow under both dry and wet weather conditions;
- Flow projections;
- Model evaluation of system performance under existing and future conditions; and
- Model documentation.
