Data Acquisition and Management

The Data Acquisition & Management team (DA&M) provides critical operation and control information to the Bureau’s Combined Sewer Overflow program. DA&M collects data from a citywide system of pump stations, flow monitors, and rain gauges, which is in turn used for monitoring and analyzing the operation, maintenance, repair, and design of the City’s wastewater and stormwater collection system, and for notification and compliance with Federal and State regulations. The team operates, maintains, designs and supports the bureau’s HYDRA system 24/7, facilitates public notification for the CSO control program, and conducts monitoring of City wastewater and stormwater collection systems.
