City Plans Flow Monitoring Project

ADS® Environmental Services, a provider of networked flow monitoring and Underground Intelligence(r), has been awarded a four-month contract from the City and County of San Francisco Public Utilities Commission. This project includes the installation and operation of 100 ADS Model 1502(tm) temporary flow meters. The project objective is to collect sufficient and accurate flow information for the San Francisco Combined Sewer System to calibrate the City's hydraulic model.

"We selected ADS based on price and their track-record for successfully executing similar projects on schedule and with good results," said Andrew Lee, Infrastructure Development Program Engineer for the City and County of San Francisco Public Utilities Commission. "Accurate combined sewer flow monitoring data is required for the City's Clean Water Master Plan and ADS has the technology as well as the ability to meet our aggressive schedule."

The city is in the process of developing a 30-year Capital Improvement Program for its wastewater system, and it is important that good flow monitoring data be collected during a wet weather window in order to successfully calibrate the model. ADS was selected as the lowest priced proposal that met the project requirements, which included: + 5% accuracy as substantiated by third party verification; a minimum 90% uptime for all meter locations; CSO flow monitoring project experience; as well as service and equipment performance under quality control guidelines such as ISO 9001.
