Collection Systems Modelers are responsible for designing, developing, and maintaining mathematical models of collection systems. These models are used to simulate the behavior of the system and to identify potential problems. Collection Systems Modelers typically work in a team environment with other engineers and scientists.

1. Data Collection and Analysis

Collection Systems Modelers begin by collecting data on the collection system. This data includes information on the physical characteristics of the system, such as the size and shape of the pipes, the location of the pumps and valves, and the topography of the area. The data also includes information on the flow rates and pressures in the system.

• Collecting data from a variety of sources, including field measurements, historical records, and GIS data.
• Analyzing data to identify trends and patterns.

2. Model Development

Once the data has been collected, Collection Systems Modelers develop a mathematical model of the system. The model is typically created using computer software. The model simulates the behavior of the system by solving a set of equations that represent the physical laws governing the flow of water.

• Developing mathematical models of collection systems using software such as SWMM or InfoWorks.
• Calibrating and validating models to ensure accuracy.

3. Model Application

Once the model has been developed, Collection Systems Modelers use it to simulate the behavior of the system under different conditions. This information can be used to identify potential problems, such as flooding or backups. The model can also be used to evaluate the effectiveness of different solutions, such as new pumps or pipes.

• Using models to simulate the behavior of collection systems under different conditions.
• Identifying potential problems and evaluating solutions.

4. Report Writing

Collection Systems Modelers typically write reports to document their findings. These reports may be used by engineers, scientists, and decision-makers to make informed decisions about the collection system.

• Writing reports to document findings and recommendations.
• Presenting findings to stakeholders.
